ABSTRACT:
A combined solar-wind energy conversion system in which the combined effects of solar and wind energy are utilized in raising water from a lower to an upper water storage tank to increase its potential energy for generation of electricity. Incoming solar energy heats water to form steam which is temporarily stored. The stored steam is vented to one of first and second steam storage tanks from which it is coupled to first and second water pumping tanks. When the water enters one of the water pumping tanks, it forces the water temporarily stored therein to flow upwards the first steam storage tank. As soon as the water pumping tank is emptied, the steam condenses forming a partial vacuum in the tank. The vacuum causes water to be drawn from the lower water storage tank into the corresponding water pumping tank and the process repeated. The second water pumping tank is filled while the first water storage tank is emptied. Water flowing from the first water storage tank turns an electrical generator. Wind energy is also used to raise water from the second water storage tank to the first water storage tank to increase the available energy. When excess electrical energy is available, it is used to electrolyze water into hydrogen and oxygen which are stored for later burning during periods when insufficient wind and solar energy are available.
