WebIt promises to increase the efficiency of wave energy to grid-compatible electricity conversion by 70 to 80 %, to reduce capital expenditure by 50 %, and to increase PTO lifetime to 20 years. Finally, it can be adapted to different types of wave energy converters (WECs). WebWave power is the capture of energy of wind waves to do useful work – for example, electricity generation, water desalination, or pumping water. A machine that exploits wave power is a wave energy converter (WEC).. Waves are generated by wind passing over the sea's surface. As long as the waves propagate slower than the wind speed just above, …
