    I think devices like these always capture the imagination. Cold fusion and room temperature superconductivity are two others that come to mind. The second law of thermodynamics prohibits perpetual motion or 100% efficiency.

    One of the tenants of science is being able to reproduce or duplicate an experiment or device. That is how cold fusion and room temperature superconductivity were found to be non existent (up to now). If this fellow is legitimate, he can provide plans or instructions to make a similar device. Getting a patent for such a device is difficult because patent officers will not allow perpetual motion devices (because of the second law of thermodynamics).

    Magnets and magnetic fields have long been a 'source' for such devices, including the earth's magnetic field. However, none have 'panned out' to create a new era of scientific knowledge and discovery. There is a reason some scientific principles are declared 'laws', that is because they are true 100% of the time (i.e. cannot be violated). I wish him luck and can appreciate his enthusiasm and creativity.

    I think we can all agree on one thing: That guy is better at molding shapely tits than he is making legitimate perpetual motioin.

    Um, because if its continued motion depended upon someone adding energy (by lifting up a cuckoo clock weight once a week), it wouldn't exactly be what your thread title claims it is.

    Would any of you believers be interested in a bridge? :evil:rofl

    The ideal almost perpetual motion machine would be something like a flywheel on magnetic bearings in a vacuum. Even then, no perfect vacuum exists and it will eventually slow down.

    So why are these supposed perpetual motion machines always such complicated mechanisms; full of components which must have friction and slow things down?

    Simple - to obfuscate how they feed energy into the system and to fascinate the audience.

    No one would believe a simple flywheel because they can see it is not special. They need to see an Escher-esque ramp system or other plausible looking mechanism to believe in.

    The thing is, a successful perpetual motion machine would still only be a curiosity.

    The difference between a very low loss bearing and a no loss bearing would save some energy in machines, but it won't generate any energy. It might let you save 30% on your fuel costs in your truck, but it won't make the truck run for free.

    What you want is not a machine which is 100% efficient (breaking the second law of thermodynamics, you can't break even), but one which is 150% efficient, or even just 100.001% efficient (breaking the first law of thermodynamics, there's no such thing as a free lunch).

    You doubters are really messing up a good idea here.

    Our scepticism is keeping the entry price cheaper for canny investors like yourself.

    I like how there are springs. The minute there is a spring flexing you can say that the flexing of the spring creates heat (bend a paper clip back and forth till it snaps and feel the edge (warm yes). Since the spring flexes, heat is made, heat dissipates, hence there is loss energy and non-perpetual motion.


    The windmill with the magnets is kinda close to what this guy has rigged up, ONLY, the magnets are not connected to the windmill, they are on a separate disc that moves in such a manner that it times the approach of the magnet to the track so that it is propelling the ball around the ring. Which is similar to using a sensor and electromagnets that are switched, in fact an electromagnet with a switch mechanism would probably be better even as you could feed power in to accelerate/decelerate the windmill. And since the windmill is on a shaft horizontally and balanced you could take power off that shaft to do work. Of course because feeding the power into the magnets isn't fully efficient, and there will be heat from electric current to dissipate, there will be losses, but it can do work.

    Oh wait....

    That's an electric motor.



    SOOOOO this device is essentially a mechanically activated very balanced motor with a smooth track and the repullsion set by the harmonics of a vibrating rod in the column. That will eventually stop. Perhaps if the sculpture is really clever the deflection of the persons walking around the gallery bending the floor can accelerate the device.. for more perpetual motion, like a kinetic watch.

    My first read through your post I was starting to think to myself "I wonder if he knows he's describing a basic electric motor..."

    This is NOT CS&M

    It IS a technical forum.

    Is this enough of a warning?
