you can see some draws... try it
High Lifter Gravity Pump ... Use water to pump water (no other power required). These pumps can provide up to 1200 gallons per day and lift water over 1000' straight up. A piston uses the pressure of water flowing downhill to pump a portion of the water up higher than the original water source. No priming needed. When there's water, the High Lifter starts itself. Easy to install
Inventor Sam Barzanji’s amazing gravity pump is nearest thing ever to a perpetual motion machine. Powered solely by the weight of water inside it, it can raise 9,000 litres of water a day, day in, year out, to a height of 60 metres, even out of a sludgy river. Sam was a top irrigation engineer in Iraq until, for being a Kurd, his house was shelled to bits in l997. Fleeing to this country, but unable to bring his family with him, he lived on benefits for the six months it took for his refugee status to be confirmed, then got a job delivering pizzas.
“Faced with an empty life,” he said, “I had to try to do something useful.” With some help from Business Link Wessex and a DTI Smart grant, field trials of Sam’s pump were recently completed at the Southampton Institute, Sir Christopher “Hovercraft” Cockerell’s old alma mater. At around £150, Sam’s invention would not only be two-thirds cheaper than the standard aid-agency hand-pump. Thanks to an un-named zillionaire philanthropist, it now looks to have a life-saving future in the world’s irrigation-barren regions.
Not that Sam ever stops. His latest invention, a so-called “edge-driven” pump has a cleverly suspended rotor with hole at the centre instead of an axle. The beauty of it is that it’s completely clog-proof, with any kind of waste being blown through the hole. Applications include sewage pumping, bow-thruster units for yachts, an intravenous micro-pump for people with slow blood circulation, and even as a motor for surfboarders who want to get out there fast and catch the wave. Following the Iraq war, Sam was able to speak on the telephone to his family for the first time in six years. “Now,” he says, “I have a very full life once more.”
