Traveling Wave Hydrokinetic (TWH) Pump
Pliant Energy Systems has taken a completely new approach to harvesting the vast un-tapped energy coursing through the world's streams and rivers without the need for expensive and environmentally damaging dams. Key features of the company's TWH generator technology are: Deflects heavy objects, resists entanglement High survivability and resilience Low secondary structure costs Low installation costs Easy retrieval and re-deployment for lower maintenance costs Animal and human safety Effective in shallow or slow-moving water
