Really cool was that ground tetherted flying machine. Years ago, I proposed something similar in the Invent the Future contest. I called it, The Biyou Skimmer, as it was proposed to travel over the Lousiana biyou to Texas. Mine had electric propellers with the track having a dual purpose of tethering the vehicle and delivering electricity. Each "station" had acatapult system for efficiency. The beauty of the system was it was aerodynamic allevoation supported, so the track was only for guodance .
