Exotic motor solutions and interesting coincidences.
The way how to see things makes artists.
When we are looking at the image, we have the right to use imagination. And sometimes in the well-known things like maps of the shopping centers have similar details with some exotic space engines. The thing is that those details might be only coincidence, but they are opening fascinating ideas in the mind of the people. The image that is on the wall of the shopping center would seem like a thing, that NASA and DARPA created during their research and study project what is handling the use of Casimir-effect (1) for interplanetary flight. The engine is known as the "Quantum vacuum thruster" (2).
The motor that doesn't need extra propellant is the dream of the engineers. The question is, "does it work" or can it create thrust, what is enough power to create the levitation (3).
There is made many tests with those types of motors, which are using radio waves or photons, but the problem is that the thrust of those motors is very weak. And by using the radiowaves the acceleration to the speed of light would take even millenniums. But there have been plans to use things like pushing the free ions by using the magnetic field to backward.
The problem with modern long-term operating drones is the corroding of the moving parts.
This kind of system is the most modern innovation. The use of a Casimir-effect is also a very interesting thing, but there are found many technical problems with that kind of engine. So this kind of very exotic propulsions are only at the theoretical level, but if the researchers can create that kind of thing, what has enough thrust the aircraft can fly forever.
Of course, we could make things like drones, what is flying by using laser light and solar panels. But the problem with those drones is that things like bearings and moving parts are corroding, and that will limit the operational time of the drones. So this makes many research plants and researchers to find the solution, what replaces the moving parts of the motor, by using the stable parts.
