Renderings of Handwavium pt. 2
More on antigravity ... I decided the basic shape of a lift generator will be a torus. The torus holds the unobtainium you spin to generate the lift force. This force is generally directed at a right angles to the torus. Obviously other systems modify that (I'm calling the craft hoppers as opposed to calling everything a lifter. I'm sure hopper pilots hear people make that mistake all the time. It's like calling a Cessna a prop or an F-15 a ... nevermind!) Otherwise the hopper would never go anywhere. The secondary systems keep the force directed downward for starters and the airfoils make sure the thrust is directed under the center of mass (for the most part it moves a bit back and forth to facilitate climbs and dives.) The foils direct thrust for movement. The torus' power is related to its surface area. What if we double the dimensions of the hopper? Poor little motor looks overworked. Especially since the craft's mass is now eight times the originals
