Tapered Channel – this is a tapering collector which funnels incoming
waves into a shoreline reservoir, which is set at a small height above mean sea
level. The shape of the collector is such that, as it narrows, the wave travelling
down it increases in height until it overtops the channel and flows into the
reservoir. The water trapped in the reservoir flows back to the sea through
a conventional low-head hydroelectric generator. The largest plant of this size
was 350 kWe but there are currently plans for a 1Л MWe scheme in Java
(Tjugen, 1995).
