A team at Columbia University hope to employ the energy produced by bacteria when they expand and contractA small Lego device on the shelf of professor Ozgur Sahin’s office at Columbia University could open up the opportunity of another form of renewable energy,and one that is much cheaper than solar and wind. Sahin has used the simple gadget to prove that evaporating water can be used to generate power, which could eventually lead to energy being generated from still reservoirs. At the centre of the research by Sahin and his team in New York are spores of common soil bacteria that expand, or much like a muscle,when there is moisture in the atmosphere, and contract in drier conditions.
