Xtreme Energetics’ ultra-efficient, pretty solar systems catch HP’s eye
Hewlett-Packard, tapping into its IP back catalog, recently announced that it would license its thin film transparent transistor technology to Livermore, Calif.-based Xtreme Energetics (XE) to develop advanced concentrating photovoltaic (CPV) solar arrays for rooftops and utilities.
HP’s thin, flat transistors, which are made of cheap, plentiful zinc and tin, will create a tracking system that directly focuses sunlight on XE’s proprietary solar concentrators. These will allow XE’s concentrators to achieve double the conversion efficiency of… Continue Reading
Sunrgi claims bargain-basement power prices from new solar concentrator design
When looking at next-generation renewable technologies, you’ll hear a lot of claims about how cheaply they can create electricity. Usually the figures hover around 10 cents per kilowatt-hour, which is about low enough to compete with the mix of coal, oil and nuclear power most utilities use.
No such small ambitions, for a new startup called Sunrgi, which is unveiling its technology today at the annual National Energy Marketers Association convention. Sunrgi claims it can provide… Continue Reading
