Converting your existing car into a Prius like
hybrid just got a lot easier and cheaper thanks to an interesting start
up company out of Connecticut by the name of Poulson.
For about 4 thousand dollars they will install a new type of external
electric motor to each of your wheels that don't get driven by the car's
transmission. The motors are used to keep you going once the gas engine
has done most of the hard work. This can increase a car that normally
get 30 mpg to 55 or better.
They don't sell the motor to do it yourselfers yet due to some legal
issues, so you'll have to take your car to Connecticut or a
participating dealer if you want to be one of the first to take
advantage of this new technology.
