U.S. Department of Energy’s National Renewable Energy Laboratory (NREL) researchers make their case that millions of U.S. households would benefit from heat pumps. But the cost of installing the technology needs to come down to make their use a more attractive proposition. The findings, detailed in the journal Joule, quantify the costs and benefits of […]

The BMW Group’s Efficient Dynamics strategy is hunting for reductions in fuel consumption and CO2 emissions.  The targets are out there; BMW is looking at the battery electric vehicles, the full plug-ins, and the hybrids.  The goal is to increase performance in the typical BMW fashion.  The performance this time is range – distance traveled […]

From out of Norway comes a new take on the heat pump.  Scientists at the University of Stavanger in Norway (USN) are testing an entirely new kind of heat pump. While heat pumps used today typically last 10 to 20 years, the Norwegian scientists are testing an entirely new kind of heat pump. Today’s heat […]

Starting with the Ericsson Cycle idea, Purdue University researchers have developed a new type of heat pump that could allow residents in cold climates to cut their heating bills in half. Eckhard Groll, a professor of mechanical engineering who is working on the project with James Braun professor of mechanical engineering and W. Travis Horton, […]
