Green Noise Bluetooth Headset is a step in the right direction, although I think it can do with some refinements. For a first draft in the idea of having headsets that soak in the high decibels and convert them to usable energy, it is a fantastic take. Imagine cancelling all the screaming fans in a football stadium and at the same time harnessing their energy! Sounds excellent!
