As the buoy moves up and down on the waves, that mechanical energy is turned into electrical energy.
The Chevy Volt, however, is never powered by mechanical energy--it has no transmission.
They have long been employed in devices like mobile phones to filter electric signals (which can be done by converting electrical into mechanical energy and back again).
Until this new system was developed, capturing kinetic energy required converting mechanical energy into electricity, which would then be converted into chemical energy for long- or short-term storage.
All that was needed to make a mechanical energy-storage system was a good enough rotational seal, so the flywheel could spin freely inside a vacuum chamber with no air resistance.
In another exciting development, researchers at Georgia Tech have developed a self-charging power cell that's able to directly convert mechanical energy into chemical energy, making it possible to harvest up to five times more energy from footsteps.
More exotic solutions include flywheel energy storage (converting mechanical to electrical energy, and vice versa).

But Dr Tim Fox, head of energy and environment at the Institution of Mechanical Engineers, warned of a potential shortage of skilled engineers needed to build the plant.
Since the energy for driving the rear wheels is electrical rather than mechanical, this is referred to as "propshaft by wire".
