'Liberator' generates power from low-grade heat
Renewable energy company PowerVerde has successfully tested its 50-kilowatt electric power renewable waste heat recovery system — the “Liberator” — and expects to ship the first of five planned systems this week.
The shipments will go to Newton Investments BV, a renewable energy investment company in the Netherlands. The firm plans to offer green renewable energy products in the European Union using available credits and incentives.
“We believe the Liberator may be the most efficient waste heat recovery system ever demonstrated,” said Rick Davis, director of PowerVerde.
Davis added that Newton Green Power BV is in final negotiations with PowerVerde to offer the Liberator technology to private factories, farms, greenhouses, biomass plants, geothermal and government-funded programs in Europe.
“We have been evaluating renewable power systems over the past 12 years, and finally have an opportunity to offer continuous green power to our European clients utilizing newly created government incentives for this type of technology,” said Piet van der Hoop, Newton’s president. “After reviewing hundreds of renewable power companies, we believe PowerVerde has the best ability to deliver an industrial style non-intermittent continuous power product capable of creating distributed energy solutions. With several European governments mandating the eventual closure of all nuclear power plants in the aftermath of the Japanese tsunami disaster we hope to replace much of this lost capacity with megawatts of totally green power.”
PowerVerde’s technology features a gas expansion motor driven by a fluid that expands into a high-pressure gas when heated to the relatively low temperature of 160 degrees F. The system can generate energy by using waste heat or heat from low-temperature solar panels, low-grade geothermal sources or biomass burning.
