need two separate vehicles and two magnets, one weaker then the other

so the weaker one will repell the other and it will kick forward moving the other forward and rinse and repeat at a sonic speed

thats gotta generate some kinda motion

This is basically how a ~~rail cannon~~ coil gun works, just with electromagnets that can reverse their polarity.

It's a powerful way to accelerate anything — I think it's most famously used in those types of metal roller coasters that start you at a flat-with-the-ground angle, and then just fuckin launch you up a ramp to 45° with electromagnets. The issue is that you need a fuckton of energy to do that.

What we need for true perpetual energy is to just capture that guy Blanka from Street Fighter.

That's not how a railgun works, that's how a coilgun works. Railguns create a loop of electric current that flows into one "wire" (the rail), through the projectile into the other wire, and back down to the starting point again, this configuration creates a force that pushes the projectile down the rails

Ah, I appreciate the correction. I'm not an engineer but the youngest cousin of a clan of them, so I just got the highlights of the true evil genius shit. :p
