Perpetual motion machine
 
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.

Neat Factor
 
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.

Beezer 11-16-2012 12:06 PM

sorry, the physics of this universe say no.

rapidoxidationman 11-16-2012 01:21 PM

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.

P B G 11-16-2012 05:56 PM

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.
