My understanding is that high Tc superconductors have problems with large currents in large magnetic fields. As MSimon said in another thread, the field lines interfere with Cooper Pair formation, and it just doesn't work very well. This is viewed as a limit on the strength of the coils using high ...

Since we definitely don't need fusion for 1,000 years, it makes little sense to start building any fusion reactors today unless they can be competitive with current fission plants. How well are the radioactive ores distributed? If the world 'goes fission,' who's going to be sitting on the gold mines?

Did housing really drop in value? Or are prices now in line with what people are willing to spend? If you own a house on a block with one or two abandoned foreclosures, that's gonna really hurt your property value, too. Sure, there's price correction, but that varies by market (area). And why aren'...

Relativism sounds like a belief. A century and billions spent. Is there an irrefutable proof for "time dilation", "curved spacetime" and "nothing can travel faster than light"? Or, are these only dogmas that do not allow contestation? Actually, other earlier models were the dogma. Relativity took a...

At this stage the resources needed are way beyond what grassroots can do, esp given the lousy economy. EMC2 had a very popular (for a physics talk) google video going for it, and the nonprofit New Mexico development fund. But I'd be surprised if they raised more than a few thousand dollars. The Navy...

power production is coming at 1/10th of current prices I was under the impression that cost of distribution (incl. maintenance) was significant regardless of how the power is generated. A large part of the plant cost is in the turbines, etc, assuming they'll still be used with a Polywell. Now, what...

Useful service life for Polywell, esp. for rockets?
It appears that a practical Polywell will need periodic maintenance, to replace the coil casings and other parts after sputtering and neutrons have taken their toll. If we're talking stationary or earthbound applications, it's not a big deal, but what do you do on a spacecraft? Will this be a limiti...

http://www.crossfirefusor.com Wow. This guy obviously put a lot of time into the web page, but reading it made my eyes hurt. And interspersed with the diagrams etc he throws out these little gems: The travel between Earth and Alpha Centauri star, including acceleration and deceleration, will take 2 ...
