Platform for generating electricity from flowing fluid using generally prolate turbine

摘要

A platform-like device for generating electricity from moving fluids has at least two fluid turbines coupled to one another through a frame. The fluid turbines are adapted to rotate in opposite directions. The fluid turbines also provide buoyancy for the platform so that the platform is self supporting in the water. The fluid turbines preferably have helicoid flights (screw-like threads) mounted to generally prolate casings. The fluid turbines preferably connect to electric generators through belt, chain-drive, or other transmission systems. The platform may additional support a wind turbine.

1. An electricity-generating platform having a buoyancy to at least partially submerge when placed in a stream of water, comprising:
a fluid turbine configured to rotate about an axis when placed in a stream of flowing water; an electric generator adapted to generate electricity in response to rotation of the turbine; first and second buoyant lateral side supports, a central longitudinal axis of the turbine extending between the side supports; and a support frame coupling the first and second lateral support to the turbine; wherein the buoyancy of the platform is such that the turbine is at least partially submerged when the platform is placed in the stream of water; the support frame being configured to vertically raise and lower the turbine to adjust a distance between the turbine and the first and second lateral side supports.
