Researchers at the Rensselaer Polytechnic Institute have created a nano-engineered coating for photovoltaic (PV) cells that increases sunlight absorption to 96.21 percent. Reported in “New nano coating boosts solar efficiency” on CNN.com, this new technology may improve performance of PV by enabling greater energy capture. Importantly, this coating also improves energy absorption for non-direct angles between the sun and PV collector.
Solar reflectivity is only one parameter among a complex array of variables impacting PV performance. Nonetheless, the CNN article suggests that efficient solar energy absorption at high angles may eliminate sun tracking systems, which have parasitic power draws.
The first Tacoma Narrows Bridge was a Washington State suspension bridge that opened in 1940 and spanned the Tacoma Narrows strait of Puget Sound between Tacoma and the Kitsap Peninsula. It opened to traffic on July 1, 1940, and dramatically collapsed into Puget Sound on November 7, just four months after it opened.
Noting that we now live in an era of “confusion and ill-conceived stuff,” Ammunition design studio founder Robert Brunner, speaking at Gigaom Roadmap, said that by adding connectivity to everything and its mother, we aren't necessarily doing ourselves any favors, with many ‘things’ just fine in their unconnected state.
