This Video shows the build of a Solar Evacuated Thermal Vacuum Water Pump works by harnessing the energy of the sun in the day time and then uses the cold of night to create a vacuum in the system that is used to pump water. This is a working prototype of an idea on how to pump water from stagnant water sources cheaply using no moving part.By using the sun’s energy to generate both a pressure and a vacuum cycle we create a very efficient water pump, that has only two simple moving parts. 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.
