          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?

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