How so? The confirmation of wiffleball is a seriously significant advancement in plasma physics in a long time. There are also other lessons from the work that have also paved the road ahead for this approach.
Navy funding is a political animal. Its presence or absence reflects nothing on the actual work accomplished.
In fact, in my opinion, for a long shot project, they have narrowed the odds to be in the same order of magnitude for final success.
That is significant, no matter how you measure.
When compared to other efforts, the list of knowns verses unknowns presents significant favor to the polywell approach.
And that is what science is about; eliminating the unknowns.
The main limitation for any approach is plasma stability. This is where polywell is very much ahead, and proven so.
So again, I ask, "How so?"
The development of atomic power, though it could confer unimaginable blessings on mankind, is something that is dreaded by the owners of coal mines and oil wells. (Hazlitt)
What I want to do is to look up C. . . . I call him the Forgotten Man. (Sumner)
