Researchers from the Hong Kong University of Science and Technology, China (HKST) have devised an ultra-thin liquid crystal displays (LCDs) screen that operates without a power source. The compact, energy-efficient display technology of visual information may one day have applications in products such as e-book readers, flexible displays or as a security measure on credit [...]

A sponge-like plastic that sops up the greenhouse gas carbon dioxide was presented at a meeting of the American Chemical Society by chemists from the University of Liverpool. The material, a relative of the plastics used in food containers could be integrated into power plant smokestacks in the future. The report on the material is [...]

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 [...]
