When you come to a fork in the road, take it.  Yogi Berra Technology and new products continue to enhance the development and realization of electric and solar aircraft.  Two approaches to batteries, both of which explore roads less taken, have some promise for aircraft use. Shine Some Light on It What if your battery could be recharged just by exposing it to light?  A team of South Korean researchers, affiliated with UNIST (Ulsan National Institute of Science and Technology) has developed a single-unit, photo-rechargeable portable power source based on high-efficiency silicon solar cells and lithium-ion batteries (LIBs).  Rechargeable under solar or artificial light, the unit could power other electronic devices, “even in the absence of light.” Professor Sang-Young Lee and …

Dr. Yi Cui is a Stanford University associate professor of materials science and engineering and a member of the Stanford Institute for Materials and Energy Sciences, a joint institute with SLAC, the National Acceleration Laboratory.  He has spoken at three Electric Aircraft Symposiums, and has worked for at least the last decade on various technologies and tactics to bring battery science to a high level. His latest effort involves “a low-cost, long-life battery that could enable solar and wind energy to become major suppliers to the electrical grid,” according to a press release from SLAC.  Dr. Cui says, “We believe our new battery may be the best yet designed to regulate the natural fluctuations of these alternative energies.” Of concern …
