making operating with liquid nitrogen at that temperature (i.e. the b.p.) a preferable one.
I know that in many steam condensors, the water is subcooled a little below the boiling point on purpose, because pumping a saturated liquid is a PITA. If you take a saturated liquid into the suction side of a pump, the lower pressure will cause unwanted boiling (caviation) and really takes a toll on the pump impeller.
So from a practical pumping standpoint, you would want the fluid you are pumping to be at least a few degrees below the boiling point.
There's a lot of issues involved and no easy answers.
In my mind, the best answer is to change the business model. The modern recording industry is a historical accident based on a scarcity of publishing and distribution resources. This scarcity no longer exists, so trying to make that model work is doomed to eventually fail.
Music is a performance art. A business model based on a experience that is inherently uncopyable stands a much better chance of surviving.
At least a few musicians hate it that Weird Al can get away with making parodies of their songs. So should the law enable prosecution of parody or satire if it offends the original author?
It's about the fact that I don't want other people to take something that I worked hard to create and exploit it for personal gain without taking my efforts or desires into consideration.
So you want the right to control the actions of anyone who (reads your book, looks at your painting, listens to your song) forever? I agree with this poster. You don't have any natural right to control other peoples' reactions to your actions. Putting intellectual property in the same category leads to ludicrous situations:
Person A builds a house
Person B walks down the sidewalk and sees person A's house.
Person B: "I like how that house looks. I think I'll build one like that."
Person A sees Person B's new house.
Person A: "You can't build a house like that, the design is my intellectual property!"
I would love to read about that. Can you point me to where you read that? I knew that it's possible to re-use nuclear waste, but only one time, and after that you end up with, yet again, nuclear waste. Are you saying they can re-use this over and over again? And would that make it as clean as solar or wind energy? That would be fantastic!
Basically, not all fission products are equally radioactive. The largest fission product of U-235 thermal fission is an isotope of tellurium, which rapidly decays to iodine (minutes), which decays to xenon (hours). The xenon-135 decays into non-radioactive caesium. About 50 hours after the termination of fission, your iodine/xenon radioactivity is basically negligible.
The second largest is bromine-krypton-rubidium
But there are hundreds of fission products, and some of them make long-lived radioactivity.
Neutron exposure is a good way of transmuting one atom into another atom. A breeder reactor can transmute radioactive waste into stable elements and it can transmute heavy atoms into fissionable transuranics. Sometimes you put non-radioactive elements into a breeder reactor to intentionally make them radioactive, for use as nuclear fuel or bombs.
* but then again, there are plenty of slashdotters that would have you killed for believing in a god in any fashion.
I know I shouldn't feed the troll, but I can't let that one pass. Do you actually know of a single case anywhere of a murder committed by an atheist because the victim believed in god?
You've got relativity giving you headaches, then there's quantum physics telling you that the universe doesn't really exist. It's enough to make you conclude: physics? f--- it.

Surely it is conceivable to cool liquid nitrogen down a little below it's boiling point.

I have a method for bypassing advertisements on all forms of television currently in existence:
When the commercials start: go to the bathroom, get a snack/drink, perform small errands, talk to other people in the room.
Be careful, not scrupulously watching every single advertisement makes you a criminal pirate thief.

just so you know, you've got a typo in there
You can not go wrong with Allen-Bradley PLC systems. Find a large Allen-Bradley vendor (Rexel-Nelson is a good one) and use them as a resource.
Have them send a representative out to you and help tell you what product line will fit you best. That's what vendors are for.
If there is a possibility of becoming one of your suppliers, any good vendor will bend over backwards when you need help like this.
Not to mention those different copyright notices on different parts of the world

Remember those old "Celebrity Deathmatch" shows? I'd pay to see a Stephen Colbert vs. John Stewart deathmatch.
