Wave hello to new power supply

Funding from the Air Force Office of Scientific Research, and the National Science Foundation could lead to thermopower wave devices that could pave the way to environmentally friendly energy production using fuel cells. Wonjoon Choi of MIT and colleagues believe the waves may form the basis of new types of fuel cells that convert condensed liquid fuel into electrical energy in a continuous manner. The technology is already generating attention because it is non-toxic, saves energy and can create a significant amount of power in much smaller batteries.
