Photovoltaics added value to homes in six markets, according to a new report. They engaged a team of seven appraisers from across the six states to determine the value that solar photovoltaic systems added to single-family homes using the industry-standard paired-sales valuation technique, which compares recent sales of comparable homes to estimate the premium buyers would pay for PV.
Traditional light bulbs, thought to be well on their way to oblivion, may receive a reprieve thanks to a technological breakthrough.
Researchers will study the vibrations of wind turbines at a large Chilean wind farm along with health impacts on nearby residents. The goal is to make wind turbines more acceptable. Currently, scientists lack sufficient understanding of wind turbines’ noise and best ways to mitigate the effects, they say.
Graphene, the ultra-thin, ultra-strong material made from a single layer of carbon atoms, just got a little more extreme. Physicists have been able to create the first ever superconducting graphene sample by coating it with lithium atoms.
A detailed nano-mechanical study of mechanical degradation processes in silicon structures containing varying levels of lithium ions offers good news for researchers attempting to develop reliable next-generation rechargeable batteries using silicon-based electrodes.
A newly designed material, which mimics the wing structure of owls, 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.
Over time, the electrodes inside a rechargeable battery cell can grow tiny, branch-like filaments called dendrites, causing short circuits that kill the battery or even ignite it in flames. But thanks to new experiments and computer simulations, researchers have explored in detail how higher temperatures can break down these dendrites — and possibly extend battery lifetimes.
