In answer to Eric's last question, we have modified the Spheromak into
an
advanced form composed entirely of a plasma shell, vacuum field and
central magnetized plasma ring. Since the currents are energetic, the
plasma shell can be compressed by bringing the surrounding gas blanket
up to several tens of kilobars. Then the fusion energy can the liquid
density blanket into a plasma suitable for expulsion through an
inductive MHD generator. The description, some experimental results
and a patent application can be viewed on the prometheus2.net site
found in my signature.

Cheers, Paul

Mike,

BTW, due to the exceptional sustained confinement and ease and
efficiency of strong compression, we may be able to burn p-^11B.
