Cohen Home in Lenado, Colorado, is located on altitude of 2,636 meters (8650 feet) where there are only 4 and a half hours of sun per day in the dead of winter, manages to generate more power than needed. The off-grid Cohen Home is one of the most energy-efficient homes in the state with HERS… »

A team of researchers from University of Connecticut (UConn) perfected a method for creating quick-changing, variable colors in films and displays. They managed to make them less expensive and less wasteful to manufacture compared to any previous method. The technology could be used for displays, solar cells, OLEDs, transistors, vanity glasses, or glasses used by… »

Delft University of Technology (TU Delft) is currently testing an intelligent street lighting system on their campus. Compared with the street-lighting system in use, the proposed intelligent system can reduce energy consumption and CO2 emission by up to 80%, it is cheaper and easier to maintain, and it could lessen the problem of light pollution… »

last year we wrote about a group of researchers at the California Institute of Technology (Caltech) who have been conducting a field study at an experimental two-acre wind farm in northern Los Angeles County. In their new findings, the researchers  came up with a way to increase the power output of wind farms simply by… »

Virginia Tech’s Robotics and Mechanisms Laboratory team dominated the international robot soccer competition known as RoboCup 2011 which was hosted this past weekend in Istanbul, Turkey. Team CHARLI took first place at the Louis Vuitton Humanoid Cup, the Adult Size class with the humanoid robot CHARLI-2, and the Kid Size class with the miniature-humanoid-robot DARwIn-OP…. »

Almost as cheaply and easily as printing a photo on your inkjet, an inexpensive, simple solar cell can be created by special “inks” deposited on the paper. The researchers from MIT came with a process essentially the same as the one used to make the silvery lining on packages you see in everyday groceries –… »

The Crosby Street Hotel has been awarded LEED Gold certification and it is verified by the Green Building Certification Institute (GBCI). The 11-story hotel has nearly 7,900 square meters (85,000 square feet) with 86 guest suites, a 99-seat screening room, meeting rooms, a guest library, drawing rooms and a lounge, as well as a lobby… »

Automated helpers in industry today are usually enclosed by protective barriers. Industrial safety regulations permit contact between people and robots only under certain conditions, since the risk of injury to humans is too great. In order to allow safer collaboration, researchers at Fraunhofer-Gesellschaf are developing a projection and camera-based system able to prevent potential collisions… »
