    I don't fully understand the physics behind the notion of perpetual motion, nor can I declare that this man's invention is scientifically legitimate. But one tinker-er to another, I thought a lot of you guys would be interested in this complicated contraption:

    The machine has some sort of monoshock running down the core of it, so, yeah, its motorcycle related!

    Interesting for sure, but I'm dubious.

    I suspect it may run for an exceedingly long time, but not endlessly. Three days of monitoring is hardly a long enough time to provide sufficient data to claim that it will run forever.

    What this machine seems to be really, really good at is conservation of energy.

    Friction would be a factor in time.

    Wonder is there was an outer space condition where much less friction was applied to the track but it was used more as a guide? When things touch & then move on, there us usually friction.

    The only thing close to perpetual motion is a woman's mouth.

    That is beautiful!
    But it's art.

    The power probably comes up the central post, that's why he has it bolted down and locked up.
    I always like to see what these guys come up with.

    Scientific sculpture - I like it, as long as no one tries to claim anything stupid.

    Well it is certainly more believable with that accent. He seems like a really cool guy, but I'm not buying any claims of perpetual motion machines without some fundamentally new and different technologies. And even then, I'm going to be skeptical.

    The concept is simple. Perpetual motion means that the machine produces at least as much energy as it uses.

    And, unless this guy has found a way to disprove Newtonian physics, it is impossible.

    Neat looking machine, but I guarantee there is an external power source that makes it move.

    If you believe this, you probably also believe the magician really did float in air, etc.

    There is a power source hidden in there, lots of places to hide it.

    Does it make sound?

    If so, that means it can't run forever (unless it also somehow harnesses the sound that it makes ... and with 100% efficiency).

    Google Second Law of Thermo.

    Cool gizmo, though.

    that one piece jump suit zipped down to the belly button kinda creeps me out...:huh

    What kind of shoes does a pedophle wear?

    White Vans...

    Any physics moran has heard of how the spin of the earth will make a pendulum move. He's getting energy from the spinning mass below it. Wouldn't work in a zero g environment.

    Nice trinket, but not a perpetual motion machine.

    Where a lot of people get tripped up by this sort of concept is that it may indeed operate for a VERY long time on the initial energy that got it started, which simply makes it an efficient machine, not perpetual motion.

    In reality his machine is similar to an orbit.

    Because springs in reality are not efficient (a vibrating spring eventually stops) just having the spring flexing is absorbing and returning energy in an imperfect way. But given enough input the ball may keep rolling for long enough to be neat sculpture.

    Harnessing that energy to do any work? No.

    Gaining more energy than it is absorbing (even if it is just absorbing energy from the vibration of people walking through a museum) = not perpetual.

    Physics just ain't broke.


    But for serious, this guy makes some great tits. Bravaaaaa :clap

    I bet if you had x-ray vision, and could see inside the center pillar, you'd see a great big one of these:

    IF it were possible to build a perpetual motion machine it would be useless except as a novelty display. BECAUSE as soon as you hooked a PTO to it it would slow down/stop.

    We need an accelerating machine.

    This^

    Even the scientist in the interview says that it isn't 100% efficient. Meaning it can't run forever. As soon as you add the mechanics to create power the efficiency would drop from the extremely high percentage it's at to something closer to the machines we already have. Also someone has to start the ball rolling right? It doesn't mean that he has a power source, it just means he has to push the ball and it can run for a ridiculous amount of time.

    That being said every machine we have now was created through an evolution of ideas. So if one man can come up with an idea that's more efficient than previously thought, maybe someone else can take that idea and improve on it. We don't necessarily need perpetual motion, but an efficiency of 80-90% could certainly change the way the world works.

    On a side note, does it seem like most of his art is just 3D porn?

    I'm embarrassed to ask now that no one else has but...wtf are those? I see pine cones/tiny grenades...then I see the image title of cuckoo clock weights...then I think, so what? Why would simple weights (given, shaped fancy like pine cones) within the pillar discredit what the video says the contraption does?

    its more than possible, its been done, i've seen it with my own eyes. ... rare earth magnets are really magnificent,, and thats all i will say about it.

    I think the Bishop is alluding that hidden behind the curtain is a cuckoo clock mechanism with the weights slowy lowering. When they reach the bottom the machine stops unless rewound.

    What? Magnetic bearings? Yeah, they do a beautiful job at reducing friction from a rotating shaft, but unless the shaft is enclosed in a vacuum, there is still friction in the system.

    Perpetual motion is a nice dream, but its a practical impossibility - even if you could harness the motion to drive power supply that kept the system up, bumping that output up to provide any useful energy will degrade the system.
