Low speed hydro powered electric generating system
First Claim
1. A low speed hydro powered electric generating system for use in rivers, ocean currents, and tidal flows comprising:
- a power generating section including a radial turbine mounted inside a central water passage attached to a downstream exit cowling of expanding area towards the downstream side wherein the turbine is constructed and arranged to cause DC power to be produced; and
a power conversion section wherein the DC power is converted to AC power.

Abstract
A low speed hydro powered electric generating system capable of harnessing the flow of rivers, ocean currents, and tides that meets the requirements of electric power companies for base load generating equipment considering availability of rated power on demand, quality of power, safety, and overall capital cost. Water will be sucked across a parallel axis radial turbine spinning inside a central water tube by a downstream exit cowling of larger cross sectional area than the turbine. The suction created from the downstream exit cowling applied back upstream through converging plates sufficiently accelerates the velocity of the water to economically produce renewable electric energy.

9. An electric generating system wherein a parallel axis radial turbine assembly spins inside of a central water passage and wherein the turbine is mounted within opposing rectangular magnetic bearings of sufficient strength so that the inconstancies of a rectangular magnet mounted on a curved surface are of no consequence.
- 10. An electric generating system wherein a DC power source of any kind is connected to a bank of solid state DC to AC inverters wherein the exact phase angle of each inverter may be communicated to and adjusted by a control computer for the purpose of coordinating the sine wave output of the several inverters so that they are all on phase together and further coordinating the sine wave output of the inverter bank to match the phase angle of the grid and where the condition of the inverters, the phase angle and other critical parameters are reported to a remote operator.
