“Thermodynamic Vacuum/Pressure Water Pump”, pumps 8 feet high with no electricity.


This is my invention called a “Thermodynamic Ram Pump (TRP’s)” that functions on the same principle as the Stirling Engine, using the sun’s energy to generate both a pressure and a vacuum cycle water pump. I use a 60″ Fresnel lens to heat the pump cylinder up to a high enough temp that we can create a vacuum even during day time temperatures once the system is shaded from the sun. This pump was able to move one gallon every cycle to 8 feet high, by creating artificial day/night cycles the pump could move about 1 gallon every 30 minutes of sunlight, or about 12 to 20 gallons a day.
