I have seen a story on the Gyro-copter and the video of the working prototype, I liked the idea until they said the selling price would be about...$100,000
They are also making a dune buggy that has a hang glider on it and the car motor turns the fan in the back...$$$
Then there is a guy in Germany, who made a pedal bike that I believe could go 60mph, just by pedaling faster, kind of a gear box motor boaster set up... you would need no fuel to travel freeway speeds on your pedal bike... bottom line he wants $44,000 for one bike... I am guessing that you can ride a non-motorized bike on the freeways in Germany.
I guess if I wanted the speed bike, the Gyro-copter or the hang glider, I would have to wait until China makes a cheap copy...
I have no need for them, because I am getting a Elio...
