Take this pic as a basic model... Would this work if there were two magnets (on the bottom) that alternate and push away from a stronger magnet (on the top) if they moved like pistons somehow fastened to the axle and thereby spinning it?

Also, could the top magnet be stronger by converting the crankshaft (or whatever its called) to some kind of generator that is wrapped in copper or some shit thereby powering the top magnet?

Try pulling your own hair until you lift yourself from off the ground.

I did and just got hurt.

Does that mean I didn't pull hard enough?

yes, pull harder. with enough force you can achieve liftoff

I've the real solution:
Replace the car with a donkey and magnet with carrot.

This obviously works, therefore magnet scenario must work.

i've always wondered why car manufacturers don't put small dynamos in the wheels of cars. connect them to rechargeable car battery, viola

same reason why the dynamos on push bikes only power the lights rather than a drive eletrical motor

well excuuuuuse me princess.

it might not keep the battery charged up, but it'd keep it going that little bit longer. gotta save the environment, man.

Sure is highschool dropouts in here, because I cannot fucking understand how people dont get Newton laws.

Wow, not a single magnet joke yet. I don't know if I'm impressed or disappointed.

they do it, but not in the wheels, they connect it directly to the engine, and it recharges the battery. its the reason you don't have to exchange car batteries every week

OP: an internal force can never change the basic direction of an object's travel.
Sit in a car and try to push it forward. Never gonna get anywhere.

>> No.952157

Jesus christ what is it with those fucking magnets.

It is just a force like any other force. Try pushing a car while sitting on the backseat, retard.

>> No.952165

That isn't saving energy, it's converting gas to electricity for the sake of not replacing the battery.

If you added dynamos to the axles of cars, due to friction it would take more power to spin them than you would get out of them.

Even if you had some elaborate generator that was only engaged when the car is coasting downhill, it would slow down the car slightly and you would have to burn slightly more gas to power the car back up the hill.

>>951704
they've been doing that for years....

>> No.952193

No.

>> No.952204

no this wouldn't work, there's no way to slow it down... it would constrantly acccelerate until you went past the sound barrier etc but you'd crash before even hitting that speed... such a bad idea seriously there is a reason people get degrees in engineering.

>> No.952453

maybe if you made the road magnetized(s) and your car was(n) and it would constantly speed up at a measurable rate. the gas pedals would make your magnetic move away from the ground or closer to decrease or increase speed and for a break have a piece of metal of the same magnetic as the ground to slowly magnetize so it would slow down your car.

>> No.952874

wouldn't work cause the magnet at the back would also be pushed away. with both magnets pushing away from each other, well there would be equal force in both directions, and since the car is heavy that's a lot of weight to push it would just end up going backwards learn to newtom

All re-tards. pronounced <reh - tard>

There is no net force on the car, only on the armatures of the magnets.
