Business Wire tells us that A123 (what a catchy name) just bought out Hymotion, the company it had been working with to develop a plug-in kit for the Prius. The kits may be available next year for about $10,000, allowing you to go about 30 miles on a four-hour charge.
Don’t get too excited just yet. Putting one on your car will void the manufacturer’s warranty and Hymotion presently plans to guarantee the kit for only two years, until they are confident it will last longer than that. At some point we enviros will need to step in to expose whatever environmental downsides are associated with nano technology, lithium mines, and the like. Get ready.
