Eco Factor: Life preserver keeps the user warm using solar energy. A Taiwanese student has developed a high-tech life preserver that looks like an ordinary plastic life preserver but has been designed to be charged using solar energy to keep its user warm even in freezing water. Dubbed LIFEON, the life preserver features a chlorophyll solar cell that is automatically charged within 10 seconds after coming in contact with water

Comments Off on Carbon nanotubes cuffs could tap waste heat from exhaust pipes for electricity

Eco Factor: Thermocell to generate electricity from waste heat. Apart from developing technology to harvest abundant solar and wind energy, there are a few researchers who are concentrating on waste materials, such as heat, which can be tapped to generate renewable electricity. Researchers at the University of Texas at Dallas have come up with a concept that could generate electricity from waste heat coming out of exhaust pipes.
