There's a new option for powering developing areas, and Isaac Newton would be proud. The GravityLight costs just $5, and uses a slowly lowering bag of sand to power the device. With one lift of the 22-pound weight, the lights are on for 30 minutes. A little elbow grease proves to be cheaper than kerosene.
In other news, Monopoly gets stripped down to game essentials, and if you think your neighbor's holiday lights are ridiculous, just wait 'til you see this lawn. See the headlines after the jump.

Nomade Express Slee...
Ugh, I hate that Monopoly game. Actually, I hate all weird iterations of Monopoly.
And that Santa army is creepy
I could see that light being useful in an attic or storage area, a place you go in to do something fairly quick. Yank the bag into place, do what you need to do, then the light turns itself off. It'd be a pain in the rear any place you needed to have light for a while, though.
Terry, the light is being developed for use in developing nations in places where electricity is unavailable or not particularly safe. For this use it is brilliant, as is the soda bottle light.
But I'd still love some for my house, so that I don't have to run behind my family members flipping off switches and muttering questions about who thinks we own the electric company.
Monopoly (ONOPO) for illiterates?
I could see a bunch of them in my hurricane kit.
