Abstract
Abstract An ocean and river water power generator has a plurality of water wheel power generators. Said water wheel power generator includes a common concrete base, a water wheel having a main shaft thereof and a plurality of water wheel impellers fixedly and radially attached to said main shaft for transforming potential energy of water in the ocean or a river to rotational energy thereof, a speed-up gear means having an input shaft thereof connected with one end of said main shaft for increasing the number of RPM of the main shaft for increasing said rotational energy.

Independent Claim
216 words
An ocean and river water power generator composed of a plurality of water wheel power generators, said water wheel power generator comprising: (a) a common concrete base having an upstream inlet end and a downstream concave arched portion, said inlet end being inclined downwwardly toward said arched portion, (b) a water wheel disposed above said inlet end and said concave arched portion, said water wheel including a main shaft and a plurality of water wheel impellers fixedly and radially attached to said main shaft for transforming potential energy of water in the ocean or a river to rotation energy thereof, said concave arched portion of the conrete base disposed beneath the main shaft of said water wheel, said water wheel having a plurality of radially extending plate frames connected to side edges of said water wheel impellers and at spaced apart intervals therebetween, said plate frames and said water wheel impellers being substantially radially coextensive, (c) a speed-up gear means having an input shaft thereof connected with one end of said main shaft for increasing the number of RPM of the main shaft for increasing said rotation energy, said speed-up gear means having an output shaft, and (d) a plurality of power generators connected with the output shaft of said speed-up gear means for generating electricity.
