The idea of unconventional energy has been around for ages and comes in many different forms. One example, in particular, is the gyro bus invented by Swiss engineers in the 1940s. The gyro bus is a bus that is powered by a flywheel. The flywheel is "charged" by spinning a large flywheel storing energy in the form of potential energy.
