<p>Vacuum-pump generating system has water-tank, vertical suction-tube split at top and merged downward into discharge-tube and turbine electric-generator. Water in suction-tube is held by atmospheric pressure at water-tank level and upward up to closed valves. Split-tubes have two valves each which alternate, and valve at merge simultaneously driven by driving-belt. When first valve is closed, second is open and freefalling water-column is creating vacuum in tube behind. By opening first and closing second valve, water from suction-tube rapidly flows to fill vacuum causing "water-hammer". Second valves have "water-hammer" driven motors which alternate to drive driving-belt. Closed second valves accommodate air-flow from air-tube which connects them. Freefalling water-columns are further guided into discharge-tube by valve at merge. Freefalling water-columns in split-tubes are alternating in order to form steady freefall flow in discharge-tube which drives turbine electric-generator.</p> |
