Before I go into this to far, I have never seen a motor cooled by imersion in a fluid. H2 cooling seems perfectly sane, as does air. As does running cooling fluids through the stator. I have heard of rotors having slip rings and cooling water too.squeakygeek posted:When conductivity is the problem I think they use mineral oil. Which looses the benefits of waters high specific heat. helno posted:Pureified water is a very poor conductor. Water inside a motor casing, interacting with commutators, brushes, and windings, isn't going to stay pure long. And "poor" at 3kv is still "holyshitlotsofpower." Running cooling water through the stator seems perfectly sane to me. You're not depending on the water being an insulator, so go for it.

Frozen Horse posted:Look on the bright side, it's not a graphite-moderated reactor. My pet favourite nuclear reactor design (not yet implemented AFAIK), remains the sub-critical accelerator-driven energy amplifier. Chernobyl. That design was (is... as it's still running in some places in the eastern bloc...) at least partially moderated by graphite. CP1 was graphite moderated. http://en.wikipedia.org/wiki/Chicago_Pile-1 So were most of the air cooled reactors. http://en.wikipedia.org/wiki/X-10_Graphite_Reactor Graphite as a moderator is scary. http://en.wikipedia.org/wiki/Windscale_fire

rainwulf posted:Believe it or not, some gasoline pumps in cars are cooled by the actual fuel flowing through them. They are, they are also typically reciprocating pumps, so the same action that actually pumps the fuel is not wasted on "moving the armature" through the fluid. It's a clever set of design choices!

that's utter nonsense. That's like using trying to break down an electroplated coin to extract the energy. .... people need to take more chemistry courses.

grover posted:There may be some way to recapture some of the thermal energy from the smelting process, but nowhere near what was consumed in the first place. Yes, scrape aluminum into a powder, combine with iorn oxide and expose to high heat. Use energy released to produce power. But that's not exactly easy to do.

I would expect there is. A combination of good thermal barriers and say... letting the cooling piles generate steam ;-)

Those orange mats are there as insulation. It stops linesman from being the jumper between circuits.

The Proc posted:Yep! Better question: How the gently caress is that guy alive? He does commercial power installs for a living. Working with high power electrical systems is literally what he does. He flipped out and deleted his old videos because people didn't understand that he IS THE EXPERT and knows what he's doing. He even understands where what he's doing will cause things like say.. spontaneous x-ray generation and the like. Most of what he does involves very, very high currents, more than very, very high voltages. Which mitigates the risk somewhat. Unless you're going out of your way to provide low resistance paths to either side of your heart, you're not going to have a heart stopping experience around a couple volts. Big sparks, lots of fun magnetics, hot things, sure. But nothing worse than working around an engine. VVVV_____ Ooops Nerobro fucked around with this message at 22:26 on Nov 6, 2012 |
