frog Future or Fiction: Revolver Turbine Prototype
By Core Jr - Feb 13, 2012
A few months ago, we invited Core77 readers to weigh-in on frog's internal design competition, frog Future or Fiction. In the inaugural edition of Future or Fiction, the design firm called on their pool of 1600 people spread across 10 studios and 15 locations around the globe to find innovative ways and unexpected solutions for rethinking how wind power could be harnessed through leveraging existing infrastructure or incorporating it into new infrastructure. The Core77 reader favorite, a portable wind turbine, was created for outdoor activity and can be easily transported and used to power electronics in remote locations.
Now after having a designer and engineer take a closer look at the idea, frog shares their rough prototype for the Revolver—a small, portable, consumer-grade wind turbine for charging mobile devices and other personal electronics when you're off the grid.
Transported in a discreet tube, Revolver is easily set up. It can generate up to 35 watts of power from just a pleasant breeze—enough to keep a laptop charged, light up a lantern, or recharge a phone, camera, and other mobile devices—simultaneously.
Watch the prototype in action after the jump and see more information about the Revolver setup and construction. Any feedback? Would you use the Revolver on a remote expedition?

Make it stackable with a central shaft interlink and guywire connection links for a permanent installation. Also, include an option for longer legs attachments for stability.!Report as spam

An Ascent solar panel currently in production generates a real 45 watts and only weighs 3 lbs. Cost $279 and it rolls up.
This wind turbine has no engineering data to support the design. Testing should should have been done BEFORE it was made to look pretty. Otherwise this is just a waste of people's time and gives YET ANOTHER bad rap to wind turbines.!Report as spam -
I love the design, it is beautiful. My comment relates to weight. If I take it hiking, even 1 or 2 extra ounces can add a lot (given everything one has to backpack in), so it should be as light as possible.!Report as spam

Oh wow, I guess the real problem or questions to be asked is the power output and the structural stability of the device.
I can image it being smaller than shown in the video and still have a relatively high output depending on the electronics within it.!Report as spam -
I've got some experience with small windturbines. The model shown in the video is unlikely to produce more than 1-2 watts. By contrast, it was sunny in those locations. A 3 square foot solar panel would easily do 5-10 watts. Much cheaper. Much more portable. Just better.!Report as spam

There are slots for pegs guys, and if you made the base too big it would increase the size of the product. I agree that magnesium seems excessive for the application...if it needs to be pegged into the ground, why not just aluminium, or GF Polypropelene? Recharging station, cool, how about spark ignition for a campfire, actually become a torch, retractable spike (or screw) for securing the product integrated at the centre of the base...handy ice pick!?! :)!Report as spam

Considering the high center of gravity, I think the base is insufficiently wide. How about a version that can be hammered/screwed into the ground..since this is for camping? Also, why magnesium? Not exactly the cheapest material...
It's a very elegant and sleek design though.!Report as spam -

Possibly useful, and certainly a clean implementation. But I wonder about two things- at 10 mph a 1 square meter ideal turbine generates 35 W, but these spiral Darrieus mode turbines tend to only achieve a third of this amount. True, power output depends on the wind velocity cubed, but it would be nice to have actual numbers here. Also, the base has to be much larger or it will tip over in even modest winds.!Report as spam

hell, i'd use it every day in my office....!Report as spam

SpareOne Phone by NextOfKin Creatives
Sustainability notwithstanding, the disposable mobile phone is certainly a practical solution for emergencies, travel, children and disaster relief. Insofar as these are the applications of any disposable phone, they're listed as "Use Cases" on SpareOne's website; the true innovation behind the device lies in its shelf life of 15 years,...

Li-Fi Could Transform Both Public and Private Spaces (If It Doesn't Give You a Splitting Headache)
We all know fluorescent bulbs flicker; wave your hand in front of one and you see the stroboscopic effect. And even though the lights can flicker faster than the human eye can detect, it can still cause problems: "Although humans cannot see fluorescent lights flicker, the sensory system in some...

Visualplanet's Touchfoil Turns Virtually Any Surface into a Virtual One (i.e. a Touchscreen)
Touchfoil is a proprietary technology that is designed to turn any large area of glass—a retail display window was their inspiration—into a "huge interactive surface that behaves just like the latest tablet devices." The transparent film can be fitted (or retrofitted) to the inside or underside of any nonmetallic surface...

TRAIL$: A Modern Parable, by Dot Samsen
Architect-turned-interaction-designer Nitipak "Dot" Samsen first caught our attention a couple years ago, when he'd just completed his MA in Design Interactions at the Royal College of Art. For the 2009 thesis show, he exhibited series of coin flippers, a diverting exercise in iteration and probability if nothing else.For his latest...
