This is more general, regarding my old ideas.
Even as a child, it seemed primitive to me that a car was being pushed off the ground, that planes were taking off from the air and ships from the water.
All of these devices should have an independent drive, so the car would not be dependent on icy roads, the plane from turbulence and the ship from the waves ... even spaceships would be easily propelled in empty space.
The basis for such a drive would be an electric motor and a mechanical device, or two, to counteract the backlash.
The thrust would be so large that the device would no longer be used not only in space but also on earth in all means of transportation.
For a start, I would protect the device with a provisional patent, and after one year with a real patent, if something needed to be changed.
I know a few companies are dealing with this, my approach is more out of the box, I think more mechanically and in the direction of great utility of the device, I see it practically in the vehicles of the future that will float in the air without the help of propellers or wings.
If anyone else was willing to start this affair with small stakes and some effort put into it, we can talk a little.
