<p>A sea-wave power plant comprises one or more channels, each externally defined by a hollow column (24a-24j), which internally can be supplied with water from below through at least one opening (26), and where, within the hollow column or each hollow column (24a-24j), a piston is disposed, preferably a float piston (32), adapted to rise upon water influx from below and sink upon outgoing water flow from the respective hollow column (24a-24j). The upward and downward displacement movement of the piston or each piston (32), respectively, can be converted into a rotational movement in one and the same direction, and this mechanical rotation energy may, possibly, be converted into electric energy through a generator. Said hollow column(s) (24a-24j) are mounted in upright positions on a submersible, moorable, ballastable/unballastable buoyancy body (10), the hollow column(s) (24a-24j) thereof having at least one first, through-going port (26) communicating with the hollow column cavity and lying at a level below the underside of the piston (32) when the piston (32) occupies the lowermost position thereof.</p> |
