Energy retrieval from sea waves

Szelangiewicz T., Żelazny K.

Zeszyty Naukowe Akademii Morskiej w Szczecinie

2015

nr 41 (113)

30--34

Seas and oceans occupy approx. 71% of the Earth. On their surface wave action of stronger or weaker magnitude can be observed throughout a major part of the year. Wind-generated wave action contains energy, which can be retrieved and used for electrical current production. The paper shows what energy is contained in wind-generated waves on various ocean areas, presents dynamics of water movement in a wave as well as several examples of calculation results of the velocity of water particles and hydrodynamic pressures occurring in a wave.
