There is a close relationship between energy and water. Producing energy uses water, and providing freshwater uses energy. Keeping U.S. power on each day requires the electric sector to withdraw approximately 200 billion gallons of freshwater per day to cool the nation’s nuclear, coal and natural gas power plants. On the flip side, energy is used to treat and pump approximately 400 billion gallons per day of freshwater to our homes, farms and businesses. California alone uses 19 percent of its electricity for water applications while nationwide treating and distributing drinking water and wastewater together account for 3 percent of energy use.
Bourne Energy, a renewable energy company, sees a major opportunity in the energy-water connection to develop a new source of renewable power. 600 billion gallons of moving water a day holds significant amounts of potential hydrokinetic power. In response, Bourne Energy has developed the RiverStar-Regenerator (RS-RE) system to capture this energy and convert it to useful electricity.
The Regenerator is a self-contained device highly scalable for each power site with units ranging from 3 to 20 feet and power outputs from 600W to 50 kW. The unit is composed of generator turbines, micro-electronics, controllers and stabilizers. The RS-RE is stealthy with a low profile, zero emissions and silent operation. It is designed to be placed in multiple power arrays in the cooling system outflow canals of many of the nation’s 5,400 power plants as well as the outflow areas of many of the 16,000 water treatment plants. It can also harness the moving water in thousands of miles of water aqueduct canals.
The Regenerator can be placed in the outfall areas of the 2,500 established hydropower dams to capture waste energy. The unit increases dam power output without requiring construction to increase reservoir or dam size. The RS-RE can also be used to produce power from many of the 80,000 non-hydropower dams in the world.
Bourne’s Regenerator is a fast track, low profile approach to providing much needed clean energy utilizing established power construction and transmission assets. Bourne Energy will have an exhibit at CleanTech Focus, Los Angeles, November 3-5, 2010.
