Could the ocean become a source of renewable energy? The company Wave Swell Energy is hoping for exactly that with its UniWave 200. The structure, with a large concrete base, has an opening for waves to enter through a hollow central chamber. As water rises and falls within the chamber, air gets pushed through a turbine, which spins and in turn generates electricity.
