The net-zero energy test house at the National Institute of Standards and Technology (NIST) in suburban Washington, D.C., absorbed a cold winter and produced a positive energy balance when it closed its one-year anniversary on July 1st. The surplus energy is said to about equal to powering an electric car rated at 2.94 miles per [...]

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 [...]

There is a fuel mileage revolution under way in over the road trucking.  Aerodynamic drag accounts for approximately 65% of the fuel consumed by semi tractor trailer rigs. There are four major areas of aerodynamic drag on a tractor-trailer, at the front of the tractor 25%, at the rear of the trailer 25%, at the [...]

The Esser-Kahn group from the University of California, Irvine led by Aaron P. Esser-Kahn, Ph.D. envisions using the amazingly efficient lungs of birds and the swim bladders of fish as inspiration for a new filtering system to remove carbon dioxide from electric power station smokestacks. The effort to capture CO2 comes from the major concern [...]

University of Washington (UW) engineers have created a new wireless communication system that allows devices to interact with each other without relying on batteries or wires for power. The new communication technique, which the researchers call “ambient backscatter,” takes advantage of the TV and cellular transmissions that already surround us around the clock. Two devices [...]
