Ohio State University researchers have come up with a two-in-one solar cell/battery combination that promises great efficiency and low costs.  What’s not to like? Unfortunately for readers of the blog, it’s initially only a stationary system that will make energy storage a viable circumstance for large power plants, but it seems that the technology could be adapted to lighter, portable applications, such as electric vehicles. Ohio State is keeping somewhat mum about the patent-pending device, which they are developing as a commercial entity under the auspices of their spin-off, Kair (K for potassium, plus air and pronounced “care”).  We’ve heard a great deal about upcoming lithium-air batteries, but potassium-air is unique.  Even more unique, this battery stores energy from its …
