As it stands, there's not a whole lot we know about pain. Where a tissue or blood sample can be drawn and studied, our nervous system comprising different kinds of cells running signals through complex piping around the body presents a difficult task for scientific research. But a new study details a technique that turns blood cells into different nerve cells, promising to improve our understanding of why things itch or burn. By extension, it is hoped that it could lead to new forms of pain relief that do away with unwanted side effects such as sleepiness or loss of concentration.

Back in 2010, stem cell researcher at Canada's McMaster University Mick Bhatia caught our attention with a novel approach to creating blood stem cells from human skin stem cells. The technique streamlined this process, advancing efforts to create blood for surgery and treat leukaemia and other cancers.

His latest work continues in this same vein, but demonstrates a method of converting somebody's blood sample into a variety of their nerve cells. This includes both the central nervous system of the brain and spinal chord, along with the peripheral nervous system in the rest of the body. The thinking is that this will allow unprecedented access to study a patient's specific neural system and address questions like why different stimuli trigger different sensations in different people.

"Now we can take easy to obtain blood samples and make the main cell types of neurological systems - the central nervous system and the peripheral nervous system - in a dish that is specialized for each patient," says Bhatia. "Nobody has ever done this with adult blood. Ever."

The patented technology could lead to new kinds of drugs that rather than create the perception of pain relief in the central nervous system, actually target the neurons in the peripheral nervous system. The hope is that this could lessen the side effects of pain relief drugs.

"You don’t want to feel sleepy or unaware, you just want your pain to go away," says Bhatia. "But, up until now, no one’s had the ability and required technology to actually test different drugs to find something that targets the peripheral nervous system and not the central nervous system in a patient specific, or personalized manner."

The research was published in the journal Cell Reports.

We've seen retro arcade-style video gaming consoles that are tiny, as well as ones that utilize an iPad and that even serve beer. The Pixelkabinett 42 has its own unique feature, however, in that it looks like a vintage industrial wooden cabinet when not in use.

The 2-player Pixelkabinett 42 is made by Swedish designer Love Hultén, the same craftsman who brought us the stylish wooden R-Kaid-42 and R-Kaid-R arcade-inspired consoles.

Its 4:3 19-inch LCD screen is contained within its lid, which folds down against the ash/American walnut cabinet body to keep dust off the controls between gaming sessions. Those controls include dual joysticks which can be switched between 4-way and 8-way modes, button controls, and a speaker that's styled to look like the planet Saturn. That speaker is helped out by a bass-blasting subwoofer.

The Pixelkabinett 42 comes standard with a JAMMA board containing a selection of classic games, although buyers can also opt for a version with an included PC that has a MAME interface, allowing for the downloading of games via USB.

If you want one, however, you'd better hurry – Hultén is only making 50 of the consoles. Prices start at €3,699 (about US$4,060).

KTM's 1290 Super Duke R falls mercifully short of expectations

The KTM 1290 Super Duke R is so close to being the perfect motorcycle

KTM's marketing team scared us a bit with its buildup for the 1290 Super Duke R, nicknaming it "The Beast" and pointing at a truly frightening spec sheet: 1,301 cc, 180 raging horsepower, 144 throbbing Newton-meters of torque, in a low-geared streetbike with a nasty attitude. Everything about it screamed "widowmaker," the next in a long line of motorcycles that were too big, too bad and too damn much for a normal rider to handle. But a funny thing happened when I took it out to test it – it didn't kill me. In fact, despite its tarmac-ripping torque and insane power levels, it proved to be a friendly, even encouraging, bike to ride, even when you switch the traction control and ABS off. What kind of black magic is this?

There are some motorcycles that scare me. The entire category of two-strokes for starters, after a brutalizing and formative early experience I had on a KL500 dirt bike. The Aprilia RSV4 Factory is another, with its terrifying launch control feature, in which you hold the throttle wide open at a standstill and then force yourself to dump the clutch.

Others sneak up on me. The BMW S1000R is a great example of a bike whose modest spec sheet hides a truly frightening level of aggression on the road. After riding that thing, the thought of KTM's 1290 Super Duke R genuinely filled me with fear.

I've always enjoyed the Super Duke series. The old 990 was a comfy, fast and torquey hooligan bike with excellent suspension. I wouldn't buy one due to its very limited tank range and boutique price tag, but I've had a lot of fun on them.

The new 1290, though, has all the hallmarks of a widowmaker. Try these numbers on for size: 1,301 cubic centimeters of bored and stroked LC8 V-twin anger, 180 peak horsepower (134 kW) – that's three-year-old superbike levels of top end performance – and 144 Nm (106 ft-lb) of torque, which is more than anything in the superbike class has ever made. In fact, the 1290 beats the 990 Super Duke's peak torque of 100 Nm (74 ft-lb) from just 2,500 rpm and upwards.

But it doesn't stop there. Most 180-plus horsepower motorcycles become manageable on the road due to racetrack-high gearing. Some of them will take you as high as 160 km/h (99 mph) in first gear, so you're only really ever experiencing half of what they can do if you ride them under the speed limit.

The KTM 1290 throws this kind of thinking out the window. First gear only takes you up to about 85 km/h (53 mph), making it short-geared even by roadbike standards. So what you've got is a historically overpowered and overtorqued engine running through extremely low gearing, in a package that weighs just 189 kg (417 lb) dry. You can see how a humble road tester with a young family might approach this thing with caution.

The spec sheet can only tell you so much, though, and within a few minutes of throwing a leg over the 1290, I had an entirely different picture of this bike.

The tire-destroying, earth-shattering power and torque are most certainly there. From anywhere on the tacho, you can unleash absolutely explosive acceleration with a firm twist of the wrist. In fact, I'd go so far as to say that I've never ridden anything that accelerates faster on the road. The sheer flexibility of that massive engine is so extraordinary you've got your choice of about three gears at any speed, and that includes standstill, as the bike will happily launch in third with a bit of a clutch slip.

It's big-twin power that'll let you overtake at the speed of thought, and if you turn off the traction control, this bike will wheelie in first, second, third and fourth gears. For all I know, it'll wheelie in fifth and sixth as well, I wouldn't be surprised at all. If you absolutely, positively need to be able to wheelie at any time, this would be the bike for you, if it wasn't for the fact that the traction control is on by default, and you have to stop the bike and play around in the menus to disable it, an annoying process which takes around 10 seconds.

But even though it has the capacity to unleash absolute hell, it's remarkably well behaved. The throttle mapping is so sweetly designed that I never bothered taking it out of Sport mode. In fact, most of the two weeks I've had this bike for, the weather has been absolutely atrocious and I've been riding it around in Sport mode with traction control off.

Ride normally, and the 1290 feels like a completely normal motorcycle. It's only when you drop your right wrist with a fair bit of aggression that the beast shows its colours.

I feel like we can gloss over handling a little. The 1290 uses KTM's in-house WP suspension at either end and this has always been top-notch gear. I found the standard settings underdamped, so I used the hand-adjusters on the forks to dial in four clicks of extra rebound, and used a screwdriver to do the same at the back. I'd have liked to add a bit of preload on the shock to quicken the steering a little, but some wag had pinched the underseat tool kit, and I was splitting hairs. Being a tall bike with a nice low centre of gravity, it handles beautifully – although I almost thought I felt a bit of frame flex hitting bumps when leaned over.

In terms of comfort, dare I say it's almost plush. The riding position strikes a great balance between elbows-out aggression and all-day touring comfort. The seat is super comfy, with lots of room to move, although there are a couple of points near the back that start poking ever so slightly into your butt cheeks after an hour or two on the road. The footpegs are slippery, so I'd almost take a file to them and hatch in a bit more grip. The mirrors are only good for elbow gazing, and the gear lever is too short, but that's about where my complaints end on the ergonomics.

Brakes are absolute top-shelf Brembo monoblocs with Bosch ABS. They bite quickly and they bite hard. For all the 1290's vaunted acceleration it almost feels like you can stop harder than you can go, although the ABS does seem to intervene earlier than on other bikes.

Fuel consumption is another nice surprise. We never recorded worse than 6.5 liters/100km (36.2 mpg) on a tank, whether commuting or going hard in the twisties. The final tank range hovered around 280 km (174 mi), which is twice what the early Superdukes would deliver under duress, and more than enough to recommend this thing as a tourer.

In fact, for all my apprehension going into this test, I've come out with precious few bad things to say about the Super Duke 1290. You'd never call it a learner's bike, but on the other hand I think just about any rider could enjoy it. It's equally happy on a wet commute or a dry set of balls-out twisties. You'd have to call it the highest performance streetfighter on the market, and yet it's a genuinely friendly machine that makes such performance astonishingly accessible.

In fact, I think it's so easy to ride that KTM might have stuffed this up a bit. This isn't supposed to be a bike with mass market appeal. This is supposed to be The Beast, the bike that strikes fear into the beige. The kind of bike that makes the Captain Sensibles of the world look at you and shake their heads. The kind of bike you give your mate a ride on, and he comes back looking pale and defeated. I put a mate on this thing, and he came back looking downright empowered. That's not good enough.

My real worry here is that with a bike like this, your riding buddies will think you're only fast because your bike is awesome. What you want is for them to take it for a ride, come back and say "Christ knows how the hell you ride that thing, I'm not man enough." For $25,000 AUD (US$17,000), you want it to be a bike they'll talk about in hushed tones decades from now.

It'd be easy enough to fix. I think KTM's design team should use the current Sport mode settings as Street mode, and get rid of the completely unnecessary rain mode. They should concoct a Sport mode throttle map fit to make strong men weep, which wouldn't be hard given what the engine can do. While they're at it, get rid of the clunky menu system and give us dedicated traction control and ABS buttons that we can switch on and off easily, on the fly. Then knock sixth gear down a few notches so you can actually use it at 100 km/h (62 mph) without feeling like you're abusing the engine, and for Pete's sake fix the speedo, as it over-reads by more than 10 percent.

Give us access to the stomach-twisting fear we secretly desire, and then give us an easy way to flick back to this magnificently rideable all-rounder for the 95 percent of the time when we actually want an excellent real-world motorcycle like you've delivered us here.

Do that, and this would be damn near the perfect motorbike. As it is, it's only brilliant.

In pictures: Rubber, metal and mud at Overland Expo West 2015

Overland Expo West 2015

Overland Expo West 2015 (Credit: C.C. Weiss/Gizmag)

Gizmag traveled to last week's Overland Expo West in Northern Arizona to explore the latest in 4x4s and adventure campers. In contrast to last year's warm, beautiful weather, this year was cold and rainy with a touch of snow, creating tire-swallowing, ego-crushing mud that left many a vehicle grinding its gears fruitlessly. It wasn't ideal weather for a camping trip, but it proved the perfect backdrop for showcasing rugged four-wheelers with specialized chassis and powertrain components.

As we prepared to venture off to Overland Expo West, we were really excited for a repeat of last year's escape to balmy Arizona weather and stories of far-flung adventure. The weather had other ideas, however. Mother Nature smothered Southern Utah and Northern Arizona in wet, bone-chilling gray during both of our travel days. The first two nights of camping were spent hiding out under the tailgate, slogging through ankle-high mud and fighting to keep the fire going in the face of a steady onslaught of rain showers. And on both nights, the rain transformed rather abruptly into dumping, mid-winter-like snow, sticking to the ground just enough to create light coverage – and more mud.

We made it to Overland Expo on Saturday morning to find that two days (and counting) of rain and snow had left a cold, muddy stew bowl in place of the field parking lot. An untimely 4WD operator error left us boating around the swamp with only two driven wheels, sending us to a screaming, sinking stop. Thankfully, a quick restart of the ignition reset the 4WD system and gave us the traction we needed to escape the tire-sucking field for the dry, hard dependability of roadside parking – an extra 10 minutes of walking was well worth the peace of mind that comes with knowing you'd definitely be able to leave at day's end. We later heard that dozens of vehicles got stuck in the mud at what could be described as both the best (plenty of rugged 4x4 and 6x6 vehicles to tow you out) and worst (kind of embarrassing to be that guy or gal at a gathering of off-road aficionados) place in the world to be spinning your tires in the slop.

The rough weather didn't do much for anyone's camping plans or overall comfort level, but it did set the perfect stage on which oversized, mud tire-equipped jeeps, trailers and expedition vehicles could strut their stuff. As one 4x4 camper van retailer told us, the mud was bad for attendees but great for business – he was selling six-figure camper vans like they were being liquidated. It didn't hurt the photography, either. Our Overland Expo West photo gallery shows the world's most extreme off-road machines in their natural element, battling it out with the mud and grime.

Ricoh develops energy-generating rubber

Ricoh's new polymer converts mechanical strain into electricity with high efficiency

Ricoh's new polymer converts mechanical strain into electricity with high efficiency

As digital technology becomes more ubiquitous and the Internet of Things takes shape, the question of how to power it all becomes more pressing. Japanese technology firm Ricoh is looking at its new "energy-generating rubber" as one solution. According the company, the new piezoelectric polymer converts pressure and vibration into electric energy with high efficiency, yet is extremely flexible and durable.

Piezoelectric materials come in two major forms; ceramics and polymers. Both are based on the principle of using mechanical strain to generate electricity and are used in electronics to provide power in specialized applications, such as vibration and pressure sensors. Unfortunately, both have their downsides. Ceramics convert vibration to energy with high efficiency, but they’re heavy, fragile, and often include toxic lead, while polymers are lighter, more flexible, and more durable, but not very efficient.

According to Ricoh, its new energy-generating rubber combines flexibility and high energy output. It's not only less fragile than ceramics, but it's also more flexible and durable than other polymers; surviving several million uses in testing. In addition, it's sensitive to light loads, yet generates high output under heavier ones.

Ricoh isn't giving much away about how the new rubber works, its composition, or specifications, but it does say that it's engaged in further research to produce a commercially viable version of the polymer for both sensors and energy applications.

Radian 2 offers Bluetooth-controlled motion time-lapse photography

The Radian 2 time-lapse motion-controller can be wirelesslyprogrammed

The Radian 2 is a time-lapse motion-controller which improves on its predecessor with the addition of wireless Bluetooth programming from iOS or Android devices, and camera control via USB. Multiple devices can be used together for multi-axis motion shots, while brackets and adapter kits allow for tilting and linear movement. The Radian 2 is currently on Kickstarter, where it has already met its funding target with 14 days left.

When Alpine Labs launched its original Radian time-lapse motion-controller on Kickstarter, it aimed to bring quality features to videographers on a budget. However, since then we've seen a selection of rival devices (such as the TurnsPro) which have tried to offer even more features or appeal to even more budget-conscious buyers. As such, the firm is back with a time-lapse ante-upping follow-up.

As is to be expected of a time-lapse motion-controller, the core ability of the Radian 2 is that it can rotate a camera as a time-lapse movie is shot. In this case it moves across 20,000 discrete positions within a 360-degree rotation, for very smooth motion, and has a standard mounting stud allowing it to easily be used with cameras from smartphones to full frame DSLRs. Battery life if said to be good for 100 hours of panning on a single charge.

In addition to panning motion, the Radian 2 can be used with an L-bracket for vertical tilting, and linear adapter kits mean it can also be used with either the Rhino Slider or StudioFX slider systems. Up to three Radian 2's can also be used together to create multi-axis motion shots, with the devices all moving in synchronization, so the connected camera is still when taking photos.

While the original Radian could be programmed via a smartphone, it had to be physically connected via the headphone jack while this was done. This time around, the Radian 2 features Bluetooth connectivity for wireless programming from the iOS or Android apps with setting options including the number of shots to be taken, angle of rotation and time duration. As well as consistent movement, advanced features include speed ramping, for changing the speed of motion within a time-lapse.

USB or trigger port connectivity between the Radian 2 and a camera also allows advanced wireless camera control from the smartphone app, with users of many camera brands able to adjust aperture, shutter speed and ISO without touching their camera. ISO and shutter speed bulb ramping is possible for creating time-lapse videos in changing light conditions. Users of some cameras will also be able to preview thumbnails of images on their phone in real time, so you'll want to check which features your camera is compatible with in the FAQ section of the Radian 2 Kickstarter page.

The Radian 2 has already reached its US$153,471 goal on Kickstarter, and the project will run to June 5th. A pledge of $220 is currently enough to get you a Radian 2, while a bundle with a linear adapter kit will set you back $320. There are other pledge levels for those wanting multiple devices, and backers should start receiving their Radian 2's in September.

You can check out the Radian 2 Kickstarter video below.

LG Watch Urbane vs. Moto 360: Quick look

Gizmag goes hands-on to compare the LG Watch Urbane (left) and Moto 360

We might see some new Android Wear gear next week at Google I/O. But until then, the LG Watch Urbane and Moto 360 are two of your best Wear smartwatches. We have both in house, so let's take a quick look.

Both the LG Watch Urbane and Moto 360 are beautiful smartwatches. Both are also big smartwatches. Put either of these next to an Apple Watch (as we did here and here) and they're both going to look enormous.

The Urbane is 13 percent taller, and both watches have the same width. The Moto is 6 percent thicker – and both look noticeably thicker than standard men's watches.

The Moto 360's big screen is still the most striking we've seen on any wearable. It's about 39 percent bigger than the LG Watch Urbane's 1.3-in display.

The Urbane's screen, however, is fully round. The Moto 360 has that "flat tire" thing going on, with a little chunk cut out at the bottom. That doesn't bother us much, as it fits the horizontal borders of the Android Wear cards that slide up from the bottom – but we also get why some folks think it looks a little odd.

Performance is a little smoother on the Urbane. The Moto doesn't have bad performance, but when you use one watch after the other, it does feel a bit choppier and laggier.

Software should be identical before long, but at the time of publication our Moto 360 hasn't yet received the Android Wear 5.1.1 update. It's Wear's biggest step forward yet, adding Wi-Fi connections, easier access to apps and touch-free scrolling gestures. The Urbane was the launch device for this update.

Battery life is the Urbane's biggest advantage: it can last close to two days with its always-on screen turned on.

If you turn on the "ambient" mode on the Moto 360 (not always on, but showing a dimmed clock more often than when the setting is turned off), it might not last a full day. With the setting turned off, it more safely keeps chugging for a day.

Right now pricing is the biggest reason to consider a Moto 360. Some retailers have dropped the leather band version to US$180 – a $70 discount over its launch price. The steel band version (seen in this article) can be had for $240 or so right now (it was originally $300).

The Watch Urbane, only available with a leather band right now, costs $350. You can, however, swap either watch's band with a default 22 mm one.

So which do you buy? Well, we recommend waiting for Google I/O before making a decision. It's just a week away, and if Google announces some Android Wear watches with big improvements there, you might regret snagging one of these right now (for what it's worth, last year two of the watches announced at I/O were shipping to customers a couple of weeks later).

It's possible we'll even see a 2nd-generation Moto 360 next week – that could help to explain the price drops we've seen on this first-gen model (though the Apple Watch could have something to do with that too).

For more, you can read Gizmag's full reviews of the LG Watch Urbane and Moto 360. And stay tuned for our Google I/O coverage next week, where we'll be on the ground.

Ecocapsule promises independent off-grid micro-living

Ecocapsule will be unveiled at the Pioneers festival in Vienna on May 28 and made available for sale at the end of this year

Bratislava's Nice Architects has revealed some renders and preliminary details concerning its Ecocapsule: a micro-shelter that operates off-grid and promises impressive sustainable technology including solar power, rainwater collection and filtration, and wind power. The firm will unveil a prototype later this month and plans to make it available for sale later this year.

Resembling the similarly-shaped Exbury Egg, Ecocapsule measures 446.8 x 240.7 x 248.7 cm (175.9 x 94.7 x 97.9 in), and comprises a total usable floorspace of 8 sq m (86 sq ft). The micro-home can be easily transported by trailer and the firm says it can serve as a tiny house, additional bedroom, office, or even as a charging point for an electric vehicle.

The snug interior includes a toilet and shower, kitchenette, work and dining area, folding bed, and both internal and externally-accessed storage. Access to the home is gained via one sole door and it sports two operable windows.

The big draw with this micro-home is the impressive sustainable technology that it promises. Packing a 2.6 sq m (28 sq ft) solar array on the roof, and an integrated battery system, Ecocapsule also sports a silent 750 W wind turbine that's set on a retractable pole. The bathroom includes a composting toilet and a shower, and a rainwater collection and filtration system offers clean drinking water.

However, when pressed on how this would work, the firm preferred to remain tight-lipped – indeed, at present, the Ecocapsule is big on promise, but the finer details are yet to be revealed.

That said, a company rep told us that a prototype will be unveiled at the Pioneers festival in Vienna on May 28 and we can expect more details to emerge then. Availability is slated for later this year and while price hasn't been revealed yet either, the firm says it will be competitive

B-Unstoppable combines a mini tank and a drone

B-Unstoppable takes to the air when it can't climb over what's on the ground

A couple of years ago, UK-based product designer Witek Mielniczek turned to Kickstarter to fund B – a combination radio-controlled car and quadcopter. Its ability to both fly through the air and drive along the ground was certainly intriguing, although its ability to traverse rough terrain wasn't necessarily phenomenal. That's why he's now created B-Unstoppable, which swaps wheels for neoprene tank-like treads.

As with the original B, the idea with this model is that users can drive it along the ground until the going gets too tough, and then just fly it over the impassable stuff. Unlike the wheeled version, however, it can turn 360 degrees on the spot – plus it has a lot more traction.

Tread tension is maintained by arms at either end, which flex in and out by up to 4 mm as the vehicle goes over obstacles. The propellers sit in line with the treads when in "ground mode," and are located so that they're not thrusting air down into the main body of the vehicle when in flight.

Power is delivered by a 900-mAh lithium-polymer battery, providing approximately 9 minutes of flight or 18 minutes of driving time.

While front and rear LED running lights are standard, a camera is extra. Buyers can install a camera of their own on the basic model, they can opt for a version with a built-in 720p DVR camera module that records footage for subsequent viewing, or they can go with a 720p FPV (first person view) package.

Mielniczek has returned to Kickstarter to fund production of B-Unstoppable, where a pledge of £55 (about US$85) will currently get you the basic version – when and if it's ready to go. A pledge of £79 ($123) is required for the DVR version, while the FPV package is going for £89 ($138). The wheeled B, incidentally, is now in production.

B-Unstoppable can be seen in flight/on the ground, in the video below.

Pole Position pickup rides the rail for tweakable tone

The single humbucker block can be moved back and forth along the rail with a just light touch

The single humbucker block can be moved back and forth along the rail with a just light touch

Mike Canavan is on a mission to bring guitarists the "greatest possible range and control over their tone" on a single instrument. The patented Pole Position Sliding Pickup System allows players to change the position of a guitar's pickup relative to the strings on the fly. This means a string-picker can opt for a bright bridge tone or a fat, warm neck tone, or anything inbetween – all with just a light touch from the picking hand.

Canavan reports that the Pole Position guitar has been two years in development, with several prototypes being created, including mechanisms with wood sliders and metal poles, before the current single rail setup was installed in the carved out pickup cavity of a Strat-shaped guitar. He says that the single humbucker block can be moved back and forth with a just light touch and players can look forward to wide changes in tone and subtle accents. When not sliding along the rail, the pickup block will stay put at a desired position until moved again.

For the final production model, Canavan intends to use maple or ash for the body, and a maple neck topped by a maple fingerboard. He's aiming for an overall weight of under 5 lb (just over 2 kg). Future plans include tremolo system options, the introduction of a model which allows a player to switch the humbucker to single coil operation and a hollow body version.

The Pole Position system is certainly an interesting idea, but that cavity looks like a bit of a dust trap that could prove awkward to clean. It's still in development though, and perhaps that open design will change ahead of the projected consumer release in the (northern) summer of 2016. Before that, Canavan is raising funds on Kickstarter for the push to market availability.

To get one of the first Pole Position guitars out of the shop, backers will need to pledge at least US$350. If all goes to plan, delivery is set to begin in July of next year. The video below shows Canavan demonstrating the system.

Hydrogen-powered Hycopter quadcopter could fly for 4 hours at a time

Horizon hopes to set a new endurance record, with its long-flying Hycopter drone

When people suggest possible uses for electric multicopter drones, it frequently seems like they're forgetting something – presently, most such aircraft can only fly for a maximum of around 25 minutes per battery charge. Horizon Energy Systems, however, is developing a quadcopter that should do a lot better. Known as the Hycopter, the fuel cell-powered drone is hoped to be capable of 4-hour flight times once completed.

In a clever design feature, the Hycopter stores 120 g (4.2 oz) of hydrogen gas at 350 bar (5,076 psi) in its existing structural tubing – no separate canister is required.

Although those refillable tubes are made of clear acrylic in the pictured display model, they'll be constructed from polymer-lined 5 mm-thick carbon fiber tubing in the functional prototype. According to Horizon, that amount of hydrogen should provide the same amount of energy as 3 kg (6.6 lb) of lithium batteries.

The gas is converted into electricity by a lightweight lithium polymer hybrid fuel cell. Altogether, the complete drone should weigh a total of 5 kg (11 lb), and be capable of carrying a payload of up to 1 kg (2.2 lb) – although when it's carrying that much of a load, its endurance will be more around the 2.5-hour mark. Additionally, the location of the payload can be adjusted, in order to keep the weight distributed evenly.

Taras Wankewycz, Horizon's Group Chief Executive Officer, tells us that the flying prototype is almost ready to go, and should be making its first flight later this year. In the meantime, the company is taking preorders for the Hycopter from interested parties. Final pricing has yet to be determined.

Vortex bladeless turbines wobble to generate energy

Groups of Vortex units can be placed close together as the disruption of the wind stream is not as critical to operation as it is for traditional, blade-driven wind turbines

Looking somewhat like a giant reed gently swaying in the wind, the new Vortex bladeless wind-driven generator prototype produces electricity with very few moving parts, on a very small footprint, and in almost complete silence. Designed to reduce the visual and aural impact of traditional spinning-blade turbines, this new device takes advantages of the power contained in swirling vortices of air.

Many opponents of spinning wind turbines point to their supposed danger to birds and other flying animals, as well as their rather noisy operation and – particularly in commercial installations – their enormous size. Though these may well be excuses by those who prefer to stay with older electricity generating technologies that they know and trust, standard wind-driven turbines do have these issues and this tends to hold back their universal acceptance and use.

This is where the creators of the Vortex bladeless believe that their device has the advantage. A relatively compact unit, it relies on the oscillation of its reed-like mast in reaction to air vortices to move a series of magnets located in the joint near its base to generate electricity.

Though obviously not as efficient as a high-speed, directly wind-driven turbine, this is offset by the fact that the Vortex has fewer moving parts and is, according to the creators, up to 80 percent more cost effective to maintain. Coupled to the notion that it supposedly has a greater than 50 percent manufacturing cost advantage and a 40 percent reduction in its carbon footprint compared to standard wind turbines, the system also seems to offer direct economic advantages.

We've explored a number of bladeless wind-turbines before – the Solar Aero turbine being one (though, by definition, not really bladeless as it merely covered the spinning blades with a housing) and the Saphonian being another. The latter being more of a true bladeless "turbine," it still required hydraulic actuation of pistons to generate electricity, so its efficiency was probably not all that great (and, to be perfectly frank, it was not strictly a turbine either as it had no spinning parts).

The Vortex, on the other hand, is purported to take advantage of the swirling motion of wind and not direct force like the aforementioned units. This means that it can generate energy from the repeating pattern of vortices (known as the Kármán vortex street), which are generated as the air separates to pass by a blunt body, such as the Vortex structure itself.

This also means that groups of Vortex units can be huddled closer together as the disruption of air movement in the wind stream is nowhere near as critical as it is when positioning standard, blade-driven wind turbines. This will also help ameliorate the inherent efficiencies in each unit as they can be grouped much closer together than their standard turbine counterparts and, therefore, potentially generate more power per square meter.

The first model to be made available commercially will be known as the Mini: a 4 kW, 12.5 meter (41 ft) high unit intended for residential and small-scale commercial application. A larger model, dubbed the Gran, is also being designed and is a unit with a greater than one-megawatt output intended for use in large-scale power generation for industry and electricity companies.

To get their creations to production, the team at Vortex will be launching a crowdfunding campaign on June 1, with details to become available via email alerts on the company's website.

The short video below shows a Vortex prototype in action and provides some background information from its creators.

The Yazdani Studio of international design firm CannonDesign recently revealed its new living unit, dubbed Sleeping Pod, that will serve as diminutive digs for students at the University of Utah's Lassonde Studios. Featuring everything you'd expect to see in a dorm room shoehorned into a small package, Sleeping Pod could also prove a good fit for temporary housing, or serve as an additional bedroom or office space.

Currently in the prototype stage, a total of 80 Sleeping Pods will eventually serve a hacker space in the Lassonde Institute – which supports student-led businesses and entrepreneurs – and offer students a place to sleep nearby while they hang out together and try to come up with the next big idea. Additional spaces like bathrooms and kitchen will be shared between the residents.

The Sleeping Pods are built from interlocking CNC-cut plywood, with a fiberglass outer shell, and sport hookups which plug into air conditioning, electricity, and water connections. The units can be moved around if required with a pallet jack or container dolly.

The standard layout offers everything found in a typical dorm room. This includes easily-dismantled book shelves, a full-sized bed (with storage space underneath), nightstand, closet, medicine cabinet, a space for a TV, and a full length mirror – all within a total floorspace of just 5 sq m (55 sq ft). Large floor-to-ceiling windows offer plenty of light, and opening skylights are also installed. A large curtain adds privacy and integrated acoustic panels should help reduce noise.

Work on the Sleeping Pods is still ongoing, but Yazdani Studio of CannonDesign has developed an interactive experience using Oculus Rift, which the firm used to offer virtual tours of the tiny housing pod, enabling them to get feedback and develop the prototype further.

Sleeping Pod is due for completion in late 2016.

2016 Chevrolet Camaro set to tackle Ford Mustang

The Camaro's more modern styling follows a similar path to that taken by the new Mustang

The Camaro's more modern styling follows a similar path to that taken by the new Mustang

The modern muscle arena has hotted-up once again, with Chevrolet taking the wraps off its sixth-generation Camaro. With eyes set on tackling Ford's venerable Mustang, Chevrolet's new muscle car hero shares only its badges with the car it replaces.

While muscle cars of the past were powered by massive, thirsty engines, the latest of the breed can boast decent fuel economy and relatively low emissions. Chevrolet has followed Ford's lead in offering a four-cylinder turbocharged motor, although the Camaro's 275 hp (205 kW) mill produces 30 hp less than the 2.3-liter EcoBoost motor under the Mustang's hood. Chevrolet's four-cylinder challenger is also down on torque compared to Ford's Mustang, with the engine's 400 Nm falling 33 Nm short of the EcoBoost's peak.

But that doesn't stop the Camaro from going from 0-60 mph (98 km/h) in under six seconds, while Chevrolet's economy tests have returned more than 30 mpg (7.85 l/100km) on the highway.

Unthinkable though it may once have been, the entry-level turbocharged motor produces 15 Nm more torque than the V6 sitting above it in the range, although the 3.6-liter V6 does boast an extra 60 hp (45 kW) over the turbo. For the first time, the Camaro's V6 is also fitted with cylinder deactivation technology, that sees two cylinders shut off under light throttle, essentially turning the car into a four cylinder for better economy.

Topping the range is the Camaro SS, which us powered by a modified version of the 6.2-liter LT1 V8 introduced on the Corvette Stingray. However, 20 percent of the engine's components are specific to the Camaro, including new exhaust manifolds that contribute to the car's 455 hp (339 kW) power peak, up 20 hp (15 kW) on the Mustang GT. The SS also comfortably outdoes the Mustang GT's torque figure, with its 617 Nm enough to win any top-trumps contest between rival owners. All cars are available with either a six-speed manual or eight-speed automatic gearbox.

A distinctive roar is an important aspect of any muscle car, so Chevrolet's engineers have put plenty of time and effort into tuning the sound on all three engines. Owners can even get in on the act, with all 2.0-liter turbo models coming with active noise cancellation to reduce cabin noise, while the inclusion of the optional Bose audio system allows the native sounds of the engine to be amplified if so desired.

Meanwhile, the 3.6-liter V6 and 6.2-liter V8 are fitted with a mechanical sound enhancers that pipe induction noise from the engine bay directly into the cabin, while an optional dual-mode exhaust lets owners choose between "stealth" or "track" exhaust sound modes.

Chevrolet has fitted the Camaro with a new multi-link MacPherson strut setup designed to reduce squat under acceleration and provide predictable, controllable handling. Magnetic Ride Control is also optional on the range-topping Camaro SS. Helping to contain the Camaro SS' extra power are Brembo brakes measuring 13.6 in (345 mm) at the front and 13.3 in (338 mm) at the rear, with four-piston fixed calipers at all four corners.

On the outside, there's no doubting that Chevrolet's designers have done a good job. While the car is still unmistakably a Camaro, it's also grown some extra muscles. Chevy says the shapely body was subjected to 350 hours of aerodynamic testing for improved cooling and reduced lift at high speeds. Up front, an aerodynamic curtain is designed to channel air around the front wheelarches and works in tandem with functional brake ducts on the Camaro SS.

Inside, the Camaro's designers have integrated the heating and air-conditioning controls into the vent surrounds – something we've seen before on the Audi TT. Chevrolet's MyLink system is operated by an eight-inch display in the middle of the dashboard, and owners can configure the system to display information about the car's performance as well as navigation and infotainment.

The new Camaro will be put together in Lansing, Michigan, and is set to go on sale later this year. There's no official word on pricing as yet.

25 teams prepare for 2015 DARPA Robotics Challenge Finals

The robots will compete on a special obstacle course designed to simulate a disaster zone

On June 5 and 6, the 2015 DARPA Robotic Challenge (DRC) Finals will take place at Fairplex in Pomona, California. Open to the public, it will see 25 international teams compete for US$3.5 million in prizes as part of an effort to develop robots for disaster relief. Here's what to expect.

The DARPA Robotics Challenge was inspired by the Fukushima nuclear disaster following the Japanese tsunami of 2011, when the general devastation prevented workers from reaching and operating the valves that could have prevented the gas explosion that damaged the reactors. Though robots were eventually brought to the site, they were slow to go into action because of the challenging learning curve and the degraded communications infrastructure.

This led DARPA to start a competition designed to spur development of semiautonomous robots capable of acting as teammates for disaster workers rather than tools. A virtual challenge with 26 teams using simulated robots kicked things off in June of 2013. This was followed in December 2013 by a physical challenge with 16 teams using real robots kept upright by safety tethers as they negotiated obstacle courses and carried out tasks using the tools at hand rather than specialized attachments.

This year's challenge will see 25 teams competing. Half of the teams are from the United States, five are from Japan, three from Korea, two from Germany, one from Italy, one from Hong Kong, and one from the People’s Republic of China. They will be vying for a US$3.5 million total of prizes; including a $2 million first prize, a $1 million second prize, and a $500,000 third prize. The robots will be of a wide variety with some humanoid, some four-legged, and some tracked, but all will need to operate free of external power, mechanical support, and limited communications with their controllers.

The basic idea behind DRC 2015 is to make things much harder for the robots than previously.

"A substantial fraction of them will have difficulty during the challenge. We do that on purpose," says DRC program manager, Dr. Gill Pratt. "DARPA takes high risks for high rewards, and that means that we also have a lot of challenges that we expect our performers to have. So, the challenge is quite hard."

During the two-day contest, the robots will be given one hour for eight tasks; one of which will not be revealed beforehand. Each robot will need to drive to the simulated disaster zone, make its way to a building, open a door, work a valve, and cut a hole in the wall. During this, communications will be deliberately degraded, so the robots need to operate with a high degree of autonomy instead of step-by-step remote control – all while dealing with obstacles

A major difference from the 2013 competition is that the robots won't be hooked to safety tethers, so If they fall down they have to get up on their own. If they can't, the team can simulate another robot helping it up and take a ten minute penalty. All of this requires improved interfaces, sensors, and software – they even use a boosted computer system designed to simulate capabilities of field gear projected five years into the future. In addition, the robots will use improved batteries, but this is may not be enough to offset the new rule disallowing recharges during the run.

DARPA is inviting the public to attend the event to show the difference between science fiction robots and the real thing, as well as dispelling fears about "killer" robots.

Gizmag will be on the ground reporting on the action – stay tuned.

Review: Polaroid Zip portable printer

Gizmag reviews Polaroid's modern take on instant printing, the Zip portable printer

Gizmag reviews Polaroid's modern take on instant printing, the Zip portable printer

Earlier this year, Polaroid unveiled its pocket-sized Zip (Zink Instant Photoprinter) designed for linking to a smartphone to crank out full-color images on demand. Gizmag recently had a chance to put one through its paces as Polaroid goes back to its instant pictures roots.

One less obvious effect of the digital revolution is how it's changed the public's attitudes towards photography. When taking pictures meant digging out "the" camera and loading it with expensive film, family photography was a special effort that was used to preserve the memory of special moments, such as birthdays and weddings.

The rise of the small digital camera has changed all that. Look around an average room and it isn't unusual to pick out at least half a dozen cameras set in computer monitors, mobile phones, and other devices. In addition, the lack of film means that these cameras are used more socially with people snapping pictures of their lunch, cats, and the ubiquitous selfie.

For the traditional camera companies, this change caught many of them wrong footed with disastrous results – Polaroid among them. However, being able to capture an image on a phone isn't universally satisfying. Some people, for example, want a hard copy to stick in their wallet or swap around at parties, and then there's grandma for who wants a "real" picture to keep.

It's to fulfill this niche that the Zip is apparently aimed by combining a compact build, ease of use and fast printing.

Polaroid certainly got the compact part right. Measuring 2.91 x 4.72 in (7.39 x 11.98 cm) and weighing 186 g (6.7 oz), the Zip isn't much thicker than a smartphone in a heavy case and doesn't weigh much more. It rests easily in the hand with a reassuring heft and fits neatly in a jacket pocket or purse. The only obvious drawback is that the lid for loading the photo paper comes off a bit too easily with a press of the thumb.

Polaroid also aimed to make the Zip easy to set up, and it is. Paradoxically, it's so easy that it almost made setting up seem more difficult because we were expecting more steps. Setting up consists of downloading and installing the associated Zip app on a smartphone, charging and switching the unit on, then linking to the phone using Bluetooth and NFC. The app is necessary: without it the printer can't be controlled. Loading the paper is also a cinch, with the main task being to remember to put the stack in the right way up, with the small bar code card on the bottom, so it can automatically complete the setup when the first image is printed.

It has a lithium-ion battery, and you charge the Zip with an included USB to microUSB cable. The only physical control is the power button set flush in the side. It's about as simple as a printer can be.

Another reason why Zip is so simple and compact is because it uses the Zero Ink Printing (ZINK) system. Instead of ink and toner, the paper uses heat-sensitive cyan, yellow and magenta dye crystals sealed with a protective polymer overcoat. The printer selectively heats the crystals to form the 2 x 3 in (5 x 7.6 cm) images in under a minute.

The paper is not the cheapest at US$14.99 for a pack of 30, but the images are clean and smudge-free, though of low resolution and prints a bit darker than expected. You don't buy the Zip for top-notch print quality; you buy it if you want a quick and smooth process.

In addition, the paper has a peel-off sticky back, so the images can be used as instant stickers.

The Zip app that controls the printer has an intuitive interface, but too many "helpful" pop-up screens that start to annoy the second time one shows up. The app allows printing of images captured by the phone's camera or any that are in its memory, so shared or downloaded images can be used. The app also can do basic editing, so it can compensate some for the darker printing, as well as things like rotating images, resizing and applying color filters.

Since it can print any image in the phone's memory, though, you could always edit and save in a preferred image editor.

The app can also produce collages of up to nine images, though on such small printouts, it isn't much use. It can also paint and add frames, stickers, emojis and the like, which could appeal to younger users. It can even add "secret" messages by embedding a QR code that can be scanned to release site links, audio messages, and others. For the more professionally minded, the app can also use templates to create instant personalized business cards. However, the latter doesn't allow for much control of font details for the text input.

Not so much a professional tool as a casual device for friends and family fun, the Polaroid Zip may lack size, but it does ably target a neglected niche for memorabilia images or just fast hard copies of reasonable quality.

The Polaroid Niche is available for US$129.99.

Golf GTE Sport peels back the curtain on VW's performance future

The car's gullwing doors are very similar to those on the XL1

The car's gullwing doors are very similar to those on the XL1

Volkswagen has used the annual GTi festival at Worthersee to reveal the carbon-bodied and hybrid-powered Golf GTE Sport. With a history of outlandish concepts at Worthersee, the sharply-styled concept presents a more likely look at the future direction VW is taking with its GT performance brand.

Under the GTE's square-edged bonnet lies a motorsport-derived powertrain, with 220 kW (295 hp) and 400 Nm of petrol power supplied by the front mounted 1.6-liter turbocharged motor from Volkswagen's Polo R WRC. This is supplemented by two electric motors, the first of which is mounted inside the six-speed gearbox housing and produces 80 kW (107 hp) and 330 Nm of torque. The second is mounted on the rear axle, and produces the same 80 kW (107 hp) as the front motor, with 60 Nm less torque.

Unlike many performance hybrids, Volkswagen's GTE Sport doesn't just treat the electric motors as boost for the petrol engine – instead, the car is set up to use electric power at every opportunity for lower emissions and lower fuel consumption, which is put at 2.0 l/100km (118 mpg). In GTE Mode the car does take advantage of all three motors for maximum performance, hitting 100 km/h (62 mph) in 4.3 seconds on its way to a top speed of 280 km/h (174 mph).

There are three drive modes available, each offering a different combination of electric and petrol power. E-Mode is, as you'd expect, made up of only electric power, and offers 50 km (31 miles) of range without firing the rally motor. GTE Mode is the sportiest option, and takes advantage of all three motors for maximum acceleration. Hybrid mode automatically decides where the power comes from.

The Golf GTE's interior also showcases Volkswagen's vision for the driver-focused cabin of the future. It borrows the XL1's gullwing doors for easy entry, and the driver and passenger sit in separate areas, each adorned by race buckets with five point harnesses, with carbon fiber and microfiber the dominant materials throughout.

To effectively deliver information about the hybrid powertrain, speed and racetrack to the driver, the GTE Sport's instrument cluster is set up in three tiers. The closest display to the driver is the smallest and shows infrequently checked information about gear position and energy recuperation, while the middle tier shows more complex information about energy recuperation and boost intensity. The third display is the largest, and shows information about speed or, if the car is in GTE Mode, the ideal racing line.

Ergonomically, the cabin has been designed so everything falls easily to hand, including the drive mode switch which is roof-mounted for a fighter-jet feel.

On the outside, VW has taken the Golf's famous profile and made it much more aggressive, with carbon fiber bodywork that includes lovely details like integrated vents in the c-pillars. Up front, the blue grille from the production Golf GTE has been adapted to fit the concept's striking styling, while an aggressive double splitter gives the car a proper motorsport look. At the rear, a massive diffuser is the dominant feature, although the car's "floating" rear wing also does a good job of grabbing your attention.

The Golf GTE Sport is only a concept, but it almost certainly provides a clear indication of where VW plans on taking its incredibly successful GTi nameplate next.
