Saltwater and sludge could give us an inexhaustible supply of energy

Splitting water into hydrogen and oxygen is generally considered a fantastic way to get a renewable power source. The problem is how exactly you go about splitting the water. Current methods require some power input in order to kickstart the reaction, reducing its effectiveness as a sustainable power source, since… » 9/23/11 6:40am 9/23/11 6:40am

As a result, one of the big questions for alternative energy researchers is how we can pull biofuel from protein. Especially because proteins… » 3/08/11 7:20am 3/08/11 7:20am

The Next Alternative Energy Solution? Human Hair

Milan Karki, an 18 year-old from a rural village in Nepal, has invented a type of solar panel that replaces expensive silicon with cheap, easily replenished human hair. Melanin, the pigment in human hair acts as a conductor for solar energy, and hair, unlike silicon, can be easily replaced, giving the panels a longer… » 9/10/09 9:30am 9/10/09 9:30am

Whales have given us a reliable source of energy for centuries: oil for our lamps, wax for our candles, and of course margarine. All that's required to harvest these lovely fuels is wholesale slaughter of the harmless creatures, and that's starting to go out of fashion, mostly because the whales were starting to go… » 7/14/08 9:37am 7/14/08 9:37am
