At first glance it might look a bit like an elongated pedal car for kids, but its designers are convinced the HumanCar Imagine PS is a serious player in the search for cleaner, greener ways to get around. The vehicle converts the rowing motion of the driver and any passengers into rotational thrust to charge a battery and power the vehicle in conjunction with an electric motor. So not only is it healthy for the planet – it is healthy for the occupants too. And as an added bonus the vehicle can also be used store energy and act as a backup power generator to provide electricity to the home.
The HumanCar is the brainchild of Chief Scientist/Engineer Charles Samuel Greenwood P.E., who first hit upon the idea for a human powered car some 40 years ago. Sitting in a traffic jam in Silicon Valley in 1968 Greenwood noticed the many overweight commuters sitting in their cars breathing in noxious exhaust fumes. He was inspired to create a modest modification to vehicles that would reduce the need for conventional fuel, while at the same time providing exercise.
Searching for a full-body workout Greenwood eschewed a bicycle-type mechanism in favor of the rowing-like mechanism and developed the forerunner to the Impulse PS, the FM-4 (Fully Manual – 4 people). This was a research “skeleton” car that was built to test the concept of a human powered vehicle and the lessons it provided eventually led to the development of the Impulse PS (Power Station).
