Where will lithium take us next? Hint: 500 mile batteries. Fletcher explores the future of lithium-air batteries in this excerpted chapter.

On a Two'fr Tuesday, here's an interesting development in solar cells:
http://gigaom.com/cleantech/the-story-behind-solar-startup-alta-devices-innovation/

"An Alta cell is about 1 micron thick compared with 150-200 microns for silicon cells and roughly 15 microns for cadmium-telluride, Norris said. Making thinner cells is a goal for all cell developers because it cuts costs.

At 28.2 percent, the cells are far more efficient than the most efficient silicon solar cells available on the market today. SunPower is making solar cells with 22.4 percent efficiency and panels at roughly 20 percent efficiency, the company announced earlier this month. First Solar, the world’s largest cadmium telluride cell maker, is making panels at 11.7 percent efficiency. Panel efficiencies tend to be 10-12 percent less than cell efficiencies."

So we can look forward to more improvements in Volt battery tech, as well as solar power sources to charge them.

This book is a great read. Very thorough and very accesible to the non-tech reader. The Volt is extensively discussed and many other electric cars are mentioned. A comprehensive review of the bidding to date to develop battery powered automobiles. It is worth reading.

Too bad it doesn't help me advance the lithium ion battery technology. There is nothing new in there that would help me develop better batteries for the future.
