I am trying to find the name of a man (possibly American) who invented a manpowered running machine. This machine allows a man to reach speeds up to 60 Kilometres/hour. This machine is possibly 5 years old, there was an article in New Scientist when it was invented and has also been seen on TV. This machine is like a set of stilts with a spring pack. I was wondering if you could tell me the inventors name and if he has a website or contact address.
Is it possible you are referring to Californai-based Gardner Martin - a HPV (human powered vehicle) designer? He has been designing them for a quarter of the century and won the Dupont prize for the first HPV to break 65 mph. His 'Easy Racer' still holds the World Speed Record for a multi-rider vehicle.
