At the University of Utah, Orest Symko and a few of his students are trying to make an alternative energy with sound! It works like this: you heat an enclosed area where the air will expand and increase the pressure. Then, the air will move through a filter making an unfaltering constant sound. These sound waves pass through piezoelectric devices which changes the sound into electricity. It's still a work in progress, but let's hope that they can get some good results out of it.
