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.
When you think of the DARPA Robotics Challenge, you may imagine complex humanoid contraptions made of metal and wires that move like a Terminator Series T-90. But what actually happened at the much-vaunted event was something just a bit different.
Traditional dev kits are based on a manufacturer’s microcontroller, radio module, or sensor device. The idea is to aid the design engineer in developing his or her own IoT prototype as quickly as possible. A not-so-traditional IoT development kit released by Bosch aims to simplify IoT prototyping even further.
