Saw this on the net. Very interesting.
Hybrid kit for any car or truck.
"Prof. Perry's design takes a lot of the confusion out of hybrid technology, making it more realistic and accessible to car owners. The kit attaches to the rear wheels of just about any car or truck, and is powered by a lithium ion battery in the trunk. Sure, not everyone could install it themselves, but Perry insists that if you can change your brakes, you can install the kit.
When it comes to market he hopes to retail the kit for around $3,000, with battery costs as the main factor in determining the price."
