perpetual motion

Impossible - in reality or in theory?

A bloke I work with honestly thought that it was possible to run a hydro-electric powers station to provide electricity to towns and cities whilst simultaneously pumping the used water back into the reservoir.

There's a power station in Wales somewhere which does that.
Except they pump it back at night I think.

i was going to post this thread next..

and besides, the only reason you posted it is to show that you can spell 'simultaneously'

Anyway, i set myself a challenge in my teens to try to create a PM machine... i still have many strange diagrams in my mum's loft.

I did some work for somebody a few weeks ago - he is convinced he's created such a machine too. It seems to be a mental aberration.
I asked him how he defeated friction, but he couldn't say.

I have no doubt of that

I think one of martian's "diagrams" shows a method of lubrication

The bloke you work with is right, they do exist. There is one in North Wales that does exactly that.

I think it's this one. Elan valley

Also, I think Carol Vordman was an engineer on the project.

lube? of course !!! essential for PM !!!

The Welsh one is called electric mountain iirc.

Pumping the water back up isn't an example of perpetual motion If it was possible then we wouldn't need any other form of power station.

You have just answered your own question.... But keep thinking....

It's impossible in theory. That's the first law of thermodynamics.

And in practice? Well, as I said in a different thread, there are no proofs, only counter-examples. You formulate a theory then you try to disprove it. That first law has survived many attempts to disprove it so it's a pretty reliable theory but that's all we can say. Nevertheless, it's so reliable that only the most determined inventor (or idiot) would try to build a perpetual motion machine today.

A perpetual motion machine or device is the only invention not allowed under patent laws,,, simply because such a machine/invention cannot possibly work.

With the one exception of the Inland Revenue tax collection "machine". That never ceases and seems to both accelerate and expand ad infinitum
