Abstract: A trinity hydro-pneumatic power source preferably includes a turbine, three hydro-pneumatic pressure tanks, a pneumatic pressure tank, a vacuum pump, a compression pump and a valve controller. The turbine is optimized to receive a flow of pressurized water through a water nozzle. The water nozzle receives pressurized water from one of the three hydro-pneumatic pressure tanks. The pneumatic pressure tank is used to force water out of the three hydro-pneumatic pressure tanks. The vacuum pump is used to form a vacuum in the hydro-pneumatic pressure tank, before being filled with water. A compression pump receives pressurized air from one of the three hydro-pneumatic pressure tanks to build pressure for input into the pneumatic pressure tank. The valve controller actuates a plurality of valves for operating the trinity hydro-pneumatic power source.
