Floating blue paddles dance on the waves that lap a dock in the Port of Los Angeles, silently converting the power of the sea into useable electricity.

Looking a little like piano keys, the floaters rise and fall with each wave.

They are connected to hydraulic pistons that push a biodegradable fluid through pipes to a container filled with accumulators, which resemble large red scuba tanks.

When the pressure is released, it spins a turbine that generates electrical current.
