Plates spinning when they move down and are still when they move up; the plates would have higher mass when moving down then moving up. Should work.
Okay, then here is what will happen:Sariaht said:They are spun up by an engine and stopped by a brake.
Highly unlikely. Since neutrinos only interact lightly with whole atoms and molecules, you wouldn't be able to apply the right thrust. After all, they could pass through a bar of lead that leads from Earth to Saturn and the neutrinos would barely effect it. The same goes for gamma rays, when trying to manipulate them for a rocket.Sariaht said:Perhaps you're right.
Neutrino propulsion then, NP?
