Aqua Power

Three teams of engineers are locked in a race to harness what may be the most powerful form of green energy swift tidal currents and battering waves, the power of the oceans. Each team believes it can solve a portion of the worlds energy needs. They're testing out three different machines designed to be placed in the water and convert ocean energy into electricity. But getting the machine from the design stage to implementation has been a difficult challenge and now each team is ready to install their systems and turn them on for the first time. If they succeed, they could radically change the way we power our planet.
