Of course... the villagers will probably fill the bag with kerosene.

BKITU: MayoBoy: WTF is a Coocoo?

It's a repository for small, spherical, brown edible objects.

Which are later dried and colored to make Trix.

BKITU: "Kerosene lamps are problematic in three ways: they release pollutants which can contribute to respiratory disease; they pose a fire risk; and, thanks to the ongoing need to buy kerosene fuel, they are expensive to run."

Perhaps kerosene quality is erratic between different producers, leaving the consumers at risk of buying low-quality product. If only some young, enthusiastic entrepreneur could come up with a way of minimizing the risk of fire, maybe by creating a top-quality standard oil for home kerosene use... why he'd be richer than Rockefeller in no time!

He should be aware of this pesky by-product of the kerosene refining process, though. It's far too volatile to be used by the average consumer, but I bet he could find a use for it in running his refinery's machinery....

Threadjack away from cool gravity powered light, potentially starting a fossil fuel argument in just 2 posts. Not a record, but admirable.

Strik3r: This seems like the next logical step in the evolution of the "hand-crank generators". There have been lights and radios that run on hand cranked electricity for a while now. This is basically just adding a clock type mechanism to let gravity do the cranking.

Simple ideas are usually the best.

OK.... just playing devil's advocate here....

The light is really being powered by a biological engine, which converts chemical energy (ATP) to mechanical energy via the light owner's musculoskeletal system, which hoists the weight to a certain height to create the potential energy that is converted to mechanical energy that is converted to electrical energy to power the LED.

So the light is actually powered by food.

In Africa.

MadCat221: Screwed kerosene vendors + Hired thugs targeting families that buy this = Not awesome.

Yeah, who can forget the bloody Icebox Wars of the early 20th century, with hundreds of hapless refrigerator owners chopped into frozen cubes?

Don't be ridiculous. They will burn it for witchcraft.
