Re: GravityLight: lighting for developing countries.
We have a few storm lights around the house. The have no batteries and use LED bulbs.
You just shake them and you get light for a few minutes/hours depending onhow long you are willing to shake them.
Then we also have a crank powered emergency radio:
A real pain in the ass to use, as it takes a while to build up enough of a charge to power the unit.
The use of a weight to generate the power, is pretty nifty as it frees you up for other things.
Is a person a failure for doing nothing? Or is he a failure for trying, and not succeeding at what he is attempting to do? What did you fail at today?.
