NREL Researchers identify battery second use strategies.
2015-06-25 14:31:07| Industrial Newsroom - All News for Today
Researchers at NREL are playing crucial role in identifying battery second use strategies capable of offsetting plug-in electric vehicle expenses. Second-use options support broad spectrum of sustainable energy strategies, as they increase potential for widespread PEV adoption by eliminating end-of-life automotive service costs. NREL research confirms that after being used to power car, Li-ion battery retains approximately 70% of its initial capacity—making reuse a valuable energy storage option.

Researchers Look to Design of Owl Wings to Make Quieter Wind Turbines
2015-06-22 19:02:00| Climate Ark Climate Change & Global Warming Newsfeed
Yale Environment 360: A new type of coating for wind turbines inspired by the shape of owl wings may dramatically cut noise associated with onshore wind farms, according to research from the University of Cambridge. The scientists found that an owl's flight feathers have a microscopic down-like covering and numerous other intricate design details that smooth the passage of air over the wing, scattering sound as the owl flies. To replicate the structure, the researchers looked at designing a covering that would scatter...
