Check out this awesome DIY that shows you how to make a green water pump that can pressurize water upto 28psi without use of any electricity or gas, just water. I can see this thing saving local farmers a LOT of money, great DIY!
The one I built has a few novelties that make it more reliable, cheaper and easier to operate than most of the plans you find on the Internet. It developed a steady 28psi pressure at the pump and delivered about 1,000 gallons per day where we wanted it.
last season, it hammered over 145,600 gallons of pond water up to our garden over 700 feet away and over 100 feet higher than the pond! In the process, it saved us over 485 liters of diesel fuel we would have normally used to drive our diesel tractor to pump and tow the water around our farm.
