Abstract: A reverse flow hydro electric turbine electrical generating system is present. It is labeled “reverse flow” in that the flow of the water driving the turbine is flowing against the force of gravity or, essentially up hill. The turbine system is comprised of a penstock for the intake of a flow of water current (as in a river or ocean stream) disposed at a depth equaling from about one atmosphere of pressure to as much as eight or more atmospheres. An amount of air is injected into the stream entering the penstock to about saturate to slightly supersaturate the solution, from which it enters a venturi-type reducer and then is piped upwardly to the turbine assembly. Attached to the top of the turbine assembly is a stand of relief pipes to carry the exhausting water to the surface for discharge.
