Re: High-temperature superconducting tape for magnets at 50+ tesla

"High Temperature" is relative. The paper shows they're working at 30 K and below, and the performance falls off at high current in the 30 K tests. Performance at 4.7 K is outstanding. Liquid nitrogen runs about 77 K, so you don't get this sort of performance at liquid nitrogen temps. This means I c...

Re: Sell The Whitehouse to Trump

I would rather not be a TV character or a "reality" show personality in an important negotiation. You can spin this crap until you turn it into cotton candy for all I care. I have seen zero evidence that Trump knows anything about negotiating strategy. Tactics, maybe (like leaving the table before t...

Re: Sell The Whitehouse to Trump

That's you lying, at least to yourself. Yes he's a lying megalomaniac, and more so than most Presidents. But not nearly so much as the candidate he defeated, and there's no basis at all for this --> "the one who admires murderous dictators and thinks he'd like to have the same powers". Ease off on ...

Ligon. Why should I give a flying f....? She ain't in office. But I suppose you'll tell us next that she was watching, eating a pizza. You keep thinking I'm a Hillary supporter. I simply detest the lying meglomaniac you think is God. You know, the one who admires murderous dictators and thinks he'd...

That's no accident. Mark Stanley pumped me for information on it, although I had mentioned it more than once on the comic forum.

Re: 1st Superconducting High-beta Device

As I recall Dr. Park's talks a few years ago, the beta = 1 condition with 5T superconducting magnets suggested a plasma pressure of some stupendous number like 120 atmospheres! High-performance steam boiler stuff! Dr. Bussard was always concerned with fast ion, slow neutral interactions, which produ...

Re: The list of duds

The machine I always wanted to see tested was an automobile using flywheel storage. I keep wondering just how you'd mount the rotating mass. Fully gimballed, coupling power to the wheels would be tricky, unless it was all-electric. For rigidly mounted flywheels, I would expect the vehicle would occa...

Re: A blast from the science fiction past

I was raised with a set of Encyclopedia Britannicas in the home, dated 1944. The article on Atomic Energy was surprisingly thorough, considering this was a year before Hiroshima. I recall it included both reactors and the prospect for nuclear weapons. Because most of the people capable of contributi...

Re: 1st Superconducting High-beta Device

In my personal opinion LN2 is going to be the necessary coolant do to availability and cost restraints and usability. He2 is just too hard to manage in an industrial environment. No argument there. While I was at EMC2 in San Diego, I ordered a sample of high-temperature superconducting ribbon. Prio...

Re: 1st Superconducting High-beta Device

Way cool! Wait, I guess "way cool" would be liquid helium. But pretty darned LN2 cool, anyway, and I'd love to see a Polywell built like that!

Re: Crime and Punishment: Oklahoma (& Texas) style!

Doing a little background checking, that tweet with the shot of confiscated tools is apparently the result of British police work, not US. One still must wonder how hand tools qualify as illegal weapons. If they ever found my tools, I'd probably be in for life! Just the chain saw would surely be eno...

A sweep turned those up and did not turn up a far more dangerous weapon? Surely they found ball point pens!
