University of Wisconsin-Madison engineers and a collaborator from China have developed a nanogenerator that harvests energy from a car tire’s rolling friction. Xudong Wang, the Harvey D. Spangler fellow and an associate professor of materials science and engineering at UW-Madison, and his PhD student Yanchao Mao have been working on this device for about a […]






University of Cambridge researchers have devised a new material that mimics the wing structure of owls which could help make wind turbines, computer fans and even planes much quieter. Early wind tunnel tests of the coating have shown a substantial reduction in noise without any noticeable effect on aerodynamics. Because wind turbines are heavily braked […]






A Boston College team of researchers has achieved the first ‘unassisted’ solar water splitting using the abundant rust-like mineral hematite and silicon to capture and store solar energy into hydrogen gas. So far finding an efficient solar water splitting method to mine electron-rich hydrogen for clean power has been thwarted by the poor performance of […]






UCLA chemists are developing photovoltaic cells that store the electrical energy. The work is a major improvement for capturing and retaining energy from sunlight, where the stored energy can last dramatically longer than current solar technology allows. The storage can last up to several weeks, instead of the microseconds found in today’s rooftop solar panels. […]






Researchers at the University of Twente, the Netherlands (UT), aim to build a self-regulating, mobile pilot plant for the pyrolysis of paper sludge. Paper sludge, the largest waste stream, is a nasty waste stream from paper factories made of organic molecules that are not useful and minerals. Gerrit Brem, professor in Energy Technology at the […]
