Pumping
Pliant Energy Systems
Irrigation or Filtration Pump
This application of Pliant Energy's core technology, currently funded by the US Dept. of Energy, may have its greatest impact in developing regions of the world. Pliant Energy's TWH Pump harnesses the energy of any flowing water source to pump water out of that source. No electricity or fuel required so long as the water is flowing along a river, a channel or even a shallow stream. The non-rotating action and streamlined profile of the pump makes it highly resistant to debris or heavy object impact. The soft undulating fins are harmless to people in and around the water performing daily activities like swimming, washing clothes, bathing or fishing. Potential applications include crop irrigation and pushing water at pressure through a filtration system for clean drinking water.
