A Pacific Northwest National Laboratory team found commercial buildings could cut their heating and cooling electricity use by an average of 57% with advanced energy-efficiency controls. The team built the results with a year-long trial of the controls at malls, grocery stores and other buildings across the country. The real world study demonstrated higher energy […]

Linda Larsson recently defended her doctoral thesis at Chalmers University of Technology, where she has been studying two promising aircraft engine concepts. Of the two, the propeller or dual propeller open rotor can save up to 15% and the geared turbofan up to 4%. Over the past 40 years the average annual increase in passenger […]

Scientists researching superconductors at the U.S. Department of Energy’s Argonne National Laboratory (ANL) have discovered a previously unknown phase in a class of superconductors called iron arsenides. The discovery offers new information on a debate over the interactions between atoms and electrons that are responsible for their unusual superconductivity. Ray Osborn, an Argonne physicist and […]

Researchers at MIT and Stanford University have found a new alternative for low-temperature waste-heat conversion into electricity. The conditions needed are where temperature differences exist at less than 100º C (180ºF). Vast amounts of excess heat are generated by industrial processes and by electric power plants simply to be lost into the atmosphere and out […]

Vanderbilt University researchers are imagining a future in which our electrical gadgets are no longer limited by plugs and external power sources. The intriguing prospect is one of the reasons for the current interest in building the capacity to store electrical energy directly into a wide range of products, such as a laptop computer casing […]
