Wave power is defined as being “the transport of energy by surface ocean waves.”The earliest recorded attempted use of wave power was in 1799, when a patent was filed by a man named Girard. This was the first example of an Oscillating Wave Column.
The “wave farm” was built in Agoucadura Wave Farm, Portugal, and consists of three 750 Kilowatt devices. The machines used in Portugal work by having different sections that bend as they are hit by waves, and this flex is slowed down by hydraulic rams, which pushes oil into a hydraulic motors, which ends up turning an electrical turbine. In total, the wave farm can produce 2.25 Mega Watts of electricity, which is estimated to be enough to power 1500 homes.
