Tidal stream generator
Type of tidal power generation technology / From Wikipedia, the free encyclopedia
A tidal stream generator, often referred to as a tidal energy converter (TEC), is a machine that extracts energy from moving masses of water, in particular tides, although the term is often used in reference to machines designed to extract energy from the run of a river or tidal estuarine sites. Certain types of these machines function very much like underwater wind turbines and are thus often referred to as tidal turbines. They were first conceived in the 1970s during the oil crisis.[1]
Tidal stream generators are the cheapest and least ecologically damaging among the four main forms of tidal power generation.[2]
