Which power supply for this system?

[Disturbedguy]

I've watched the videos - using a candle as a heat source (some 600C and a cold junction at zero, the poster is generating very little power.

However, rather than watch videos showing experiments with little scientific method, you might want to read this paper https://www.google.co.uk/url?sa=t&rc...MbYkZtnyXmrGfw

which measures the efficiency of a thermoelectric generator, and the output at varying temperature gradients under laboratory conditions. Then perhaps you will understand why the proposal is of little practical benefit.

But that would mean reading something factual!

Surely he / she can't do that!

[Disturbedguy]

cheap PSU`s and efficiency and badges, its not hard to make a circuit with a cheap peltier if you look around to power fans or your water block using heat from your CPU

if a company actually made a thermoelectric cooler for the retail market, it would probably cost around £200

More dross being spouted. You spout all this stuff, but don't actually back it up.

Careful with all those facts you're throwing around, might put someone's eye out !

I felt this mad after listening to Rick Astley. Nothing there either.

That's not true. He's never gonna give you up. He'll keep on trying to make that square peltier peg fit in that round hole of physical limitations to the bitter end.

its backed up in the youtube video`s and the photo`s of peltiers generating power from CPU heat

if you have a 650 watts PSU that is single rail at 53a * 12v gives you 632 watts so thats a gold rated PSU

200 watt peltiers cost £30 each that generate power at 13 amp`s, companie`s would have to buy peltiers in massive bulk to reduce the cost, as any other watt peltier would probably be seen as useless for server`s and office desktop`s if thermoelectric coolers hit the retail market, which then would need inteligent PSU`s to plug the thermoelectric cooler back into the PSU loop

You need to watch that video again and read the paper I linked to. Non of the devices are delivering 13 amps, yet alone 200 watts of power, even using an open flame as the heat source.

Anyway, I've had enough of this. It has been explained to you, but you don't seem to understand the physics involved, and the information you are posting is incorrect.

Thread closed, as this has now gone well off the original topic.

When the cause of the closure has been addressed, and although Taz (the OP) hasn't posted here since it went off track, he may want to come back and tell us what he bought - and why.

The headline in this morning's metro was "terminated". When you say addressed...

Thread resurrection time. Just to vindicate everyone who plumped for the laws of thermodynamics in this thread - someone has released a TEC cooler and it doesn't fair very well. Good review out-lining the problems and analysing the performance available on anandtech: http://www.anandtech.com/show/10695/...-cooler-review
