/sci/ give me one good reason why this would't work.

Because the only force is between the magnets and the blades, pulling them together, nothing interacting with anything else. It's the same reason you can't make your car move by pushing on the steering wheel.

Not sure I understand this. What if I just push harder, what if I hulk?

>>7647264
But in theory you can. Like how you can move in a chair without your feet on the floor by rapidly scooting your bidy

You'd only be pushing against the interior of the car though.

>>7647294
so? the engine is inside the car too

>> No.7647332

>>7647322
Yes but it turns the wheels to push against the road (which is the reaction mass). The force produced by the engine has to leave the car and interact with something outside of it.

Nice try. I almost believed you, then I remembered this time that I had sex in a car and all our shaking and bouncing around caused it to roll.

If that's true, couldn't you propel a spacecraft using the same principle? I think all that was happening there was that the car was on uneven ground and you were moving the center of gravity around.

>> No.7647366

>>7647358
Don't be absurd, do you realize how many people would need to have an orgy for the spacecraft to reach escape velocity? It would never scale up!

>> No.7647370

>>7647366
You don't need to reach escape velocities, you could use rockets to put it into orbit and proceed from there to Mars or wherever. And you wouldn't need an orgy, you could use some sort of mechanical device hooked up to a nuclear reactor to generate the force.

but there are no wheels or transmissions in space, so how do you move at all?

also what is science?

Could you do the same thing laser and solar sails?

I mean if the laser that shined on the sails was initially launched connected to the same ship, then detached and fired at the sails once separated

By throwing something out the back to push against.

>> No.7647500

>>7647460
Unless the laser stage was more massive than everything above it, wouldn't it move back more than the ship would move forward?

>> No.7647506

>>7647489
Still wouldn't work. The force would just pull the magnet and the blade towards each other.
