Pull-Out Solar Power in a Handy Carrying Case

March 18th, 2011 by  

OS – a Japanese company that makes retractable screens for projectors – has invented this very handy portable solar power-on-the-go device, that sells for ¥60,000 – or about $730.

The GSR-110B solar generator uses flexible solar cells developed by Fuji Electric Systems, and it is a mini solar setup that is completely off-grid, since it includes its own small rechargeable battery right in the case.

Each case contains a pull-out solar panel. To set it up, you simply pull it out, like pulling saran wrap from a box. Since it is thinfilm, it is reasonably lightweight at 3 kilograms, so one person can hand carry two of them long distances, and thinfilm is more sensitive to light than traditional solar – so full sun is not essential.

On the other hand, thinfilm doesn’t pack as many electrons per square inch. Each case has a potential output of 40 Watts, 16 Watts directly and 24 Watts of storage in the battery. The company says that it is enough to be able to keep the laptop charged for two hours or a little TV, for four hours.

To charge devices, simply plug in at the end of the case; there is a standard usb port for electronic devices and a socket to plug in electric appliances. To get 80 Watts, carry two of these portable generators.

Great for campers and for situations where people need to be able to hand carry their own supplies. You can rely on always being able to text or tweet for help.

Ironically, the Japanese salesman is seen in January introducing the product at a tradeshow, saying that he expects the big market will be outside of Japan.

But this would be especially useful in a disaster relief situation, like after earthquakes and tsunamis and nuclear meltdowns.  It looks sturdy and well made enough for massive orders from governments bringing in outside help.
