Revolution Revolving Door

What a smart eco-friendly idea. The Revolution Door’s concept is similar to a turbine spinning somewhere deep inside a hydroelectric dam or within wind turbine to generate renewable electricity. New York designers Fluxxlab’s Revolution puts otherwise-wasted kinetic energy from a revolving office door to good use—generating power. People exert a chunk of their own energy when pushing a revolving door around anyway, so it may as well be captured via gears and an electricity generator. Think about the thousands of revolving doors across the world spinning around all the time.
