Windbelt

I think that this is a fantastic idea – basically, it’s just a micro-generator in a similar vein to a wind-turbine, but far simpler. It’s not going to power a city, but it’ll power small appliances, such as replacements for kerosene-lamps and the like. It could even be used to charge laptops, phones etc.

More importantly, it’s simple, easy to maintain, and doesn’t have all the extra necessary maintenance and infrastructure that a wind-turbine farm would require.

Absolutely brilliant.
