Evaporation Powered Engines and Generators

Evaporation Powered Engines and Generators

Eva, the first evaporation-powered car, rolls along, thanks to a moisture mill — a turbine engine driven by water evaporating from wet paper strips lining its walls. Eva is one of the many devices created by Columbia University’s Sahin Laboratory to harness evaporation energy. The project was led by Ozgur Sahin, Ph.D., an associate professor of biological sciences andphysics at Columbia University. http://www.extremebio.org/
