Toyota only recently joined up with electric car maker Tesla, in order to share alternative battery  technology. Some of the outcomes of this include the RAV4 electric, and now the Tesla laptop battery idea. At first, Tesla Motors building powerplants by connecting thousands of laptop batteries seems nuts, but in the end it is absolutely brilliant.

Toyota, along with several other high end car makers, is turning to laptop batteries as a quick, cheap way to power electric cars, according to Bloomberg News.

Tesla has had many of its electric vehicles on the road for more than year, running on similar powerplants, and are all doing fine. No reports of hot spots in batteries packs. That's 6,831 individual cells bound together, and so far no fires or other problems have been recorded.

The solution costs less than the sophisticated lithium-ion battery packs developed by competing auto makers for their electric vehicles.

"This will more than triple sales to $60 billion in a decade," according to Sanyo Electric, the world's biggest laptop battery producer. The economies of scale might even drop prices.

Toyota will use Tesla's laptop packs in an electric RAV4 in 2012.
