Hi coverman, I tell you, really this invention don´t pass the prototype era. I´ve read several papers of Dr. Purves and there were many improvements designed for the vehicle, (closed cabin, a periscope system to improve visibility, better gearbox, etc) but this man didn´t have enough time (and money, I suposse
) to develop. This vehicle wasn ´t really a road runner. Like hovercraft, another British invention, have in free and open lands its better place, beaches, dusty roads, fields, etc. It could overpass holes more than a quarter of the diameter of the wheel long and sands weren´t a problem. A funny development of somebody who dare to imagine an alternative to traditional ways to transport. I must give you the right if you say this invention isn´t the best solution, of course, but I love when people think and put their hands at work and create something, it´s part of the engineering history and have all of my respects
. I like crazy inventions, many times are the base of the scientifical research.
Thanks and regards, Rafael
