I actually favor LN2 cooling. It reduces supply power and voltage. It keeps everything cool. It doesn't ionize. It doesn't separate into an explosive mixture under reactor flux conditions. Am I wrong in reading the MgB superconducting thread http://www.talk-polywell.org/bb/viewtopic.php?t=285 as an...

Thus the whole of polywell design to extract energy from fusion. I hope for the former and fear the latter.

Why MgB2 over other superconductors? MgB2 operates below the boiling point of liquid nitrogen (39K to superconducting temperature vs. ~77K boiling point for liquid nitrogen). Is it just cost considerations?

Presumably a lot cheaper, too, yes? One of the big costs of a steam plant are those big, rotating, copper-filled (? correct me if I'm wrong) generators.

Who is EMC2 these days?

Now that Dr. Bussard has passed, does anybody know who is running things at EMC2?

I'm sure Google isn't giving them a dime

This guy is just assuming that because Lerner is presenting at Google Tech Talks.

Lerner's Wikipedia talk page

Interesting reading: http://en.wikipedia.org/wiki/Talk:Eric_Lerner A lot of it is the "how many angels can dance on the head of a pin" sorts of arguments: Is Lerner a plasma physicist or a plasma cosmologist? Is he rejected by mainstream physicists? And who is a physicist, anyway? What are the crede...

Uh

There's something really creepy about focus fusion... their website is crawling with "please feed us" signs, none of the principals really seem to have a background in getting projects going commercially or have hardcore physics/math backgrounds ... Lerner represents himself as a "researcher" http:/...

Publish or perish?

One criticism I have read of the EMC2 group has been that the team has not published any peer-reviewed literature. Bussard said that the Navy put a gag order on publication, but this was subsequently lifted at the time they de-funded him. Does anyone know if anyone from the team plans on publishing ...

Molecular, not atomic, filtering

It's not clear from their description that atomic-level filtering would work.
