Blimps float on air and if they turn off their engines they float wherever the wind takes them. Recently in Albuquerque I saw what happens when you depend on Mother Nature to guide the direction of your endeavors in this way. I saw a beautiful and very expensive hot air balloon that got tangles up in a telephone pole and some wires. The Balloon was a total loss and everyone thank god was okay. One person was skinned up pretty good, but now one was seriously injured.
It maybe possible to build a Blimp propulsion system, which runs on a perpetual motion principal and will not need fuel of any kind to move about. I propose building a Perpetual motion motor using heat and radio waves. The radio waves will be fired into specific areas within the interior of the blimp based on a grid pattern to cause a whirlwind or Hurricane like effect. This will be done by insuring that the acoustic transducers spin slightly; the acoustic transducer panel on the inside will spin from the forward airflow with a spinner propeller on the outside hooked to a shaft and gears made of very strong but light carbon nanotubes. Inside the blimp the air will heat up from the vibrational sound waves, which will assist in keeping the blimp aloft. The interior of the blimp will be contoured in such a way to promote the Hurricane Effect. In the centerline of the interior of the blimp will be a set of sandwich sheet constructed fan propeller blade system. Inside the sand which sheets will be small crystals between copper lined patricians, these will collect electromagnetic energy from both the static of the propeller blades, as well as the acoustical vibrations. These fan blades on the inside will be inside the eye wall of the Hurricane effect and extending into the most powerful convection airflows. The shaft will continue to the back of the blimp and outside to be used for the propulsion of the blimp. If the blimp needs more power it can dive down and this will spin the acoustic transducers and provide them more energy to excite the gas molecules. Think it won
