    This guy apparently doesn’t understand the first and second laws of thermodynamics. However, in his defense, this is sorta how regenerative braking works, but with less complexity.

      As someone who sucks at physics, I’m convinced that Trollface has proposed so many solutions around the internet to provide free energy, but the capitalists are conspiring to sabotage him, just as they did to N.Tesla.

        The other one being to shine a light on a solar panel. For bonus points you include a mirror and a vampire.

          I remember the one where he uses two magnets, and the one where he wraps his head with and puts a plant inside it, so he can swim with infinite O2 supply.

      It’s a good idea, even if it can be ruled out. That person should offer more ideas. All of those Newtonian physics people never seem to offer up ideas.

        They can understand some basic concepts before you get into the math. Especially potential energy turning into heat, which children experience firsthand frequently. IMHO kids these days seem to understand energy more easily than we did; I think it’s because of video games.

    Either he’s lying about being a mechanical engineer or the barrier to entry to become a mechanical engineer is embarrassingly low.

    It this guy seriously proposing a perpetual motion machine for the purposes of EV charging? Also not that it really matters but who the hell has range anxiety on an electric bicycle. You get 30 miles out of those things easily, what sort of bike rides is he doing where you have to recharge that more than once a month?

    He should try recharging a solar panel with a light powered by the solar panel. Just achieving infinite power.

      I’ve gone as far as 55 miles in one bike ride, and hope to do a full century ride someday. 30 miles is not at all out of the ordinary for bicyclists.

      30 miles is laughably low. A single ride would drain it for me. To go to store it would take 10 miles, not counting anything else.

        A 10 mile round trip would probably take about 3 hours, it probably isn’t as far as you think it is.

          3 hours? How slow do you bike? I average 25 to 30mph on a non powered mountain bike. I could walk that in 3 hours.

          I work 18 kilometres away from where I live, that takes me 45 minutes on my acoustic bike. That’s just a little longer than 10 miles. The round trip is ~an hour and a half

      My distance to work is 12 km one way, so your battery would be empty afer two days…

      He’s probably lying. While the bar is pretty low for entry level M.E.s, it’s not quite that low yet.

      As an old Toolmaker, I have made my share of intern wannabe MEs cry after crushing their idiot ideas. I swear, the older engineers would send those clowns to me just so I would beat them about the head and neck with a stick.

      (I have a Daughter that has a PhD in ME. I warned her to turn down the free lobotomy offer upon finishing her degree. She listened and is now a happy and very, very smart Dr. of Engineering working with EV and HVAC systems)

      Tbf it wouldn’t be a perpetual motion machine because batteries – even rechargeable ones – have a limited capacity that reduces over time because they are a chemical reaction, the components of which degrade over time.

      Mechanical engineering student huh?

      1 week

      This is a normal trajectory for college freshmen. Get introduced to a bunch of basic ideas. Spitball and try to see how you can apply them. Start running into all kinds of caveats and engineering hurdles. Go back to class. Bother the RA. Maybe actually learn more about what you’re trying to accomplish. Become a better engineer.

        Knowing you can’t invent a perpetual motion machine is like high school level science, so being a first year college student isn’t an excuse.

          Hearing that you can’t and understanding exactly why are two very different states of understanding.

          One is simple recitation of a fact.

      Not believing you can create a perpetual motion machine should practically be an entry requirement. If you think you can you need to go back and do high school science again.

        Nah, engineering students often forget and design perpetual motion machines. Usually, they remember why that is stupid and impossible before they post it publicly where I can haunt them forever.

        It should be a graduation requirement. It really should be…

      Either that, or he’s not very smart, had a thought, poppet it into ChatGPT, and ChatGPT as it tends to do, affirmed his dumb idea, and he ended up asking it to make a Linkedin post for him on the idea.

      I’ve seen similar stuff from students who think they’ve cracked how something works, only to be incredibly wrong, because they only know half of what they need to, but don’t know enough to understand how little they know. It’s part of the journey of getting sorta-good at something though.
