Gravity generator, perpetual motion

Well, if we could harness gravity it would be as close to perpetual as you can get.

How we could do that, however, is left to the imagination, and I'm pretty sure that these guys don't have a clue, either.

A satellite, maybe? (if you count the potential energy in the earth's gravity well)
 
"A Brazilian-based agribusiness company says its plant in the Iroquois town of Gilman will be home this coming fall to the first generator powered exclusively by gravity."

Surely any agribusiness plant would be powered by sunlight?
 
And when we have tapped this planet of all its gravity we will float off into space to find another planet deflate. I suggest Pandora. :mad:
 
The article pulls quotes from an interview with Peter Sauer. I can sort of imagine how this interview actually went and was edited:

Interviewer: "Tell me about this technology."

"This sounds like a perpetual motion machine, which is impossible according to the laws of physics. These people are probably crackpots and should be ignored. These days, mostly you hear about perpetual motion from some sort of penny-stock swindler. Or maybe from amateurs who have misdiagnosed their own garage inventions. Like, some moron builds a wheel that spins for a long time, and thinks it's powering itself, but when you get into the details, you find out there’s a constant injection of energy at certain levels. Maybe they’re small, but over time, they’re not zero."

Interviewer: "But they say they're making 30 kW of electricity. Doesn't that change the world?"

"They're probably lying and you should say so in your article."

Interviewer. "Suppose it was real. What would it mean for global warming?"

"Not much. 30 kilowatts is down in the almost noise level of production."

Interviewer. "Really? If someone offered you a no-cost 30kW generator, how could that not be a good thing?"

"I really hope your article will make clear that these are probably scammers."

Interviewer: "I just need one quote on this, please."

"Fine, whatever. Forgetting about this Brazilian scam for a moment; energy is all about economics these days. If someone can demonstrate 30 kilowatts for free, that sounds like an interesting concept that we should hear about. Like, if you had an organic solar panel that was as cheap as a sheet of paper, that'd be interesting."

Oh, please don't say that. I am not looking forward to hearing kooks rant about "peak gravity," the coming cataclysm, and how it is all being covered up by Big Gravity.
 
Okay, let's see, if you utilize the potential energy of a gravity field, you can produce work, thereby reducing the potential energy of whatever you're utilizing it from.

This works up to a point. But at some point, you need to inject potential energy into the field in order to continue harvesting it.

So however the supposed machine works, all it does is convert some other form of energy into gravitational potential energy which is then harvested.

Am I missing anything?
 
No.
It's the cuckoo clock principle.

If they are using falling asteroids, that would be cool.
Then very hot.
Then cool again.
 
Does anyone managed to find any information on how it's actually supposed to work? "By gravity" isn't much to go on.

It's strange that they'd take out a half-page newspaper ad to announce it, but in the local newspaper only, and not even bother to mention it on their website.

We're already past peak gravity. It's all uphill from here.
 
If the people who claim to gain weight just by looking at a cinnamon bun are telling the truth, a perpetual gravity free energy machine should be quite simple. All I'd need would be two dozen of those people, a small ferris wheel, an opaque screen, a cinnamon bun, and a generator.

Using tidal water to generate power is certainly possible. The problem is the high cost of capital needed relative to the kwh produced. that's about as close as it gets to "gravity" based generator. Not quite perpetual though.

Sounds a lot like this one:

Stick around to the end, you'll be glad you did.

My reading of the transcript was that the guy was saying exactly what you suggest he might have been. Essentially, every gravity driven machine has some outside energy input, so "quotation."

Oooh, they've applied for a patent, it must be legit.

There actually are special classes in the International Patent Classifications system IPC for alleged perpetua mobilia. Class F03B 17/04 covers mechanical perpetua mobilia, H02K 53/00 covers electromagnetic ones.

Don't know if the link will work, these are the results for the mechanical ones at espacenet: F03B 17/04.

There is some nice crazy to be found there, if one is into that kind of thing... :D
