The energy is better put to use blasting ice balls because of astronomical higher
Exhaust speed fission heating cannot compete with. The static thrust higher than
Ionic motors but well below one G. More than sufficient for orbital to interplanetary
And back to orbital. The biggest problem is food supply. The Astronauts need food
At their destination hence bases to go to.
My last wheel was too crude. This upgrade explains a little further.
The flying saucer I drew will work based on existing technology and Corona Motor experiments. It’s irrelevant wether Aliens have visited this planet in the recent or distant past with regard to the workability of that saucer. Moreover the turbine can be driven by combustion gases and shift to internal storage by reason the NASA Space Shuttle Rocket of Werner Von Brawn vintage converts only 3 per cent burn into useful thrust. The Turbine is from 60 to 80 per cent effecient and direct shaft vibration to piezo-electric power over 90 per cent Effecient. The Corona Motor 90 per cent Effecient. 60 per cent times 90 per cent times 90 per cent has three per cent beat by a large margin. Even more it gets a substantial height and speed from atmospheric gases it does not have to carry internally Hense lighter. Nuclear power is for past orbital as an option.
One ampere is one coulomb charge passing a designated point in one second across a resistance of one ohm with a voltage potential of one volt and the energy of one Newton. As for Gravity, if one gram of matter transformed to light in a perfectly reflective sphere so long as no light escapes The sphere weighs the same. There is no reflective spheres around the stars but because light travels faster than matter then there is a lot of light at the perimeter of the Universe with the gravity it has taken with it, hence the material universe is expanding. But that’s not the whole story. A lot of weird things science hasn’t discovered yet. I have to wait for the silicone glue to dry before connecting the wires.
