CEO Tim Hassett said his Hybrid Plugin Electric Vehicle has patents on a technique for using heat pipes to turn engine waste heat into electricity, which can then help power the vehicle. The electric motor acts as a “load assist,” meaning the main engine doesn't work as hard and uses less fuel. It all gets attached to your rear axle.
Hassett, who turned around a company called Hawk Motors after working for GE, is working with a vehicle control company called Inverom in Chicago on the retrofits, focusing on vehicles the size of the Ford F350-550 or Dodge RAM 5500, which presently have mileage ratings in the single digits. (The company says it can turn around a vehicle in a single day.)
