Eco Factor: Solar-powered radio uses hand crank as an alternate.
Ensuring that solar-powered gadgets function when there is no sun, has been a headache for most designers for whom it’s hard to integrate an alternate charging mechanism which is as green as the solar panels. Why try to figure out a way to integrate expensive fuel cells in gadgets when a simple and inexpensive hand crank can do the job? That’s what the Solar Powered AM/FM radio does – a simple hand crank is integrated in the system to do the charging job in a green way during nighttime or an overcast day. Turn it for just one minute and the radio will play back for about thirty minutes. The Solar Radio measures just 3.25″ x 3″ x 2.25″ which makes it extremely portable. The radio can be purchased from the UsefulThings store for just $24.95.
