Here in Western Australia 10 knot winds and above are the norm. There does not appear to be any LOW speed generators (100 to 400 rpm) on the market, also no two blade self starting foils with lots of torque. The design of the foils is also intended for aircraft wings, having much greater lift and lower drag than conventional wings.
The intended market for these inventions are domestic and for caravans which often are parked under trees for shade from our searing summer sun.
Another market for the foils is pumping water on farms, a big departure from the conventional fan type.
I have no intention of seeking any financial benefit from these projects, I simply appreciate the opportunity to keep my hands busy with interesting and widely varying projects, from electronic to mechanical to electro/mechanical, to wood and metal. Trevor's mind never relaxes, I met him and his family the day after arriving in Australia in October 1964, he was then a thirteen year old with a passion for things technical. I taught him the resistor colour code and Ohms law and have followed his progress over all these years and witnessed his knowledge overtake mine many years ago. He is currently an electronics technician at our leading university, he is responsible for repairing equipment that he can't even pronounce the name of, has no circuit information for, but once he has a professor explain what it's supposed to do, he has the natural ability to sort out the problem. He also designs some specialised equipment from basic details given to him from the teaching staff. In summary, my friend Trevor is one very clever cookie and together we have a great time.
