Workout produces energy: How cool is that?
We all know that some of the most athletic people can be found in the college students population. So why not to use all that sweat into clean energy? The Drexel University Recreation Center is finally doing so. The process involves three steps: people use the elliptical machine, producing mechanical energy, which is ultimately transformed into electrical energy. So far, they managed to provide enough energy to power a sign that says “I am a dragon”, but their ambitious goal is to provide enough electricity to power the entire building. How cool is that?
