As soon as ya figure out pulling yourself up by your boot straps you'll have all the free energy hacks.

Switch the magnet for a carrot and the truck for a donkey, it’s way simpler than you tech bros are making it out to be.

The real reason is because the magnet is trying to pull the car. Have you ever tried to pull a car? You'll find it impossible even in neutral. But you'll find out pushing it is much easier.

You should instead magnetise the shell of the car, then hook to its back a magnet with the same pole as the car's back.

But how would you stop the car? If you lifted the magnet up, the car goes along with, and then you'd be going through the atmosphere.

My tax preparer randomly started telling me about how he's invested money in a guy that is developing a "reactionless space drive" that works basically like this drawing. I was fighting the eye-roll when he added that the guy solved all the problems he was having with the design by asking ChatGPT. I started to explain how ChatGPT works then thought better of it. Easier to just find a new tax preparer.

There was a kid at the summer camp I went to who had this idea. I knew it wouldn't work, but I wasn't able to explain why.

This metal arm compression device would work just fine, that metal arm would experience various stresses. Mission Accomplished. Good design.

It's the right idea. The trick is to also use an electromagnet. A few of them. Put them in a circle. Switch on one of them at a time so the magnet moves to the electro magnet. Then switch of the one electromagnet and switch on the next. Now you have a magnet spinning. Use that to mine the wheels.

Alternatively have a road full of electromagnetic in a linear fashion. That works too.

I think the reason is that the magnet is also attracted to the metal so the attraction force directions add to be net neutral

I think it's newtons first law. The force attracting the metal to the magnet is equal but opposite to the magnet on the metal.

Magnet would pull the car backwards and the metal forwards

Really? No one's posted it yet? Y'all are spending too much time in the mainstreams if this doesn't trigger your anti corpo reflex. ;p

Stand the truck up on end. It's trying to pick itself up.

Try to pick yourself up. Good luck.

It's because of those damn nonmagnetic aluminum chassis

Just need to add a hill.

Mumble, something. Magnets do no work. Mumble, mumble.

I love that apparently additional metal has to be added because the truck itself is made out of so much plastic and other nonsense that it wouldn't work with a magnet on its own.

you will get a blindspot, so accidents will happen quite often.

I'm more of an EDM guy, myself

Clearly the magnet would be attracted to the metal block, pushing the truck backwards.

The boom is actually a device which attaches the magnets to the ground. The front plate is also a powerful electromagnet which can adjust its own field to be attracted to and then repelled by the spiked, stationary magnets.

That's clearly an Acme design. It's meant to break.

Magnets don't do work

i never understand this meme, it does work, exactly as the laws of magnetism dictate, it's why it doesn't move.

It's like showing a picture of a rock with a saddle and asking why doesn't this work... well, if you mean why doesn't this move?,, you just need a steeper decline :)

If you give the arm legs, and it runs by itself, then bam! It works.

Replace the metal arm with a drone, and were getting somewhere. Like, literally.
