It would only work if you manage to keep the car at an extremely precise distance from the car in front. If you’re off by tiny tiny amounts, you’ll either lose the magnetic attraction, and stop, or you’d started getting closer fast until you’d be stuck to the car in front of you

What’s funny is this would actually work if you just pointed the magnet at other people’s cars.

Being stuck to the car in front of you is more efficient for traffic anyways

Maybe we could make a really long car
Feathercrown@lemmy.world 1 month ago
We could chain them together and make the front car really powerful. The other cars wouldn’t even need engines!
It would get kinda hard to control though. Maybe some sort of track system could keep it steady?

Use to magnets of opposing polarity, the stronger magnet should be on the bumper to push the boom forward, and drag the truck with it. /s

“this would work if you did something completely different” lmao

Am I wrong? ;)

Curses, you’ve got a point…!!

Depends on what we consider wrong. Could you pull a car that way? Theoretically, yes. Could you save energy that way? No, because the car driving in front would have to do extra work to overcome the magnet pulling it towards the car behind. You can’t cheat the first law of thermodynamics.

But that’s not my energy, the guy in front now has to pay for me to be his trailer.
Also unmeme for a second, wasn’t there news that we were able to harvest energy from brownian motion about a year ago? What happened with that?
