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.

Abstract: A very efficient direct current mobile air conditioning unit suitable for use with vehicles and capable of extended periods of operation while powered by a 12 volt battery is described. The direct current mobile air conditioning unit comprises at least one oil-less compressor and condenser coils and evaporator coils wrapped in metal gauze, where air is moved across the evaporator coil and condenser unit by highly efficient axial fans.
