If Polywell WB-8 is successful, is there less risk in building a net machine than GF?
Example of an Epic Rap Battle of History: http://www.youtube.com/watch?v=njos57IJf-0

GF
Fully funded
Pistons developed
Full sized plasma injector built, small scale plasma spheromak compression test (done), large scale testing in progress
1 meter diameter sphere built, liquid lead vortex simulation matches acoustic collapse tests, simulation indicates RM instability needs addressing, need to demonstrate smooth radial compression

EMC2 Polywell
WB-8 Navy shoestring funding, ending?
Last insight was a year ago where the review committee said WB-8 experimental results were consistent with underlying theoretical framework of the Polywell fusion concept, and recommended continuation and expansion
Status is project completion date extended to 4-30-14, no money added to FPDS report

Polywell will probably be the lighter of the two devices, I can't see the GF machine in a spacecraft. That said, the only way to tell if either is going to work is build the full scale versions.

choff, agreed on both points. It would seem to me that GF is purely for an electric utility or land based industrial market. Polywell would seem to have a smaller overall foot print as well as weight suitable for on ship power.
