A high electron density can be achieved using either a high voltage
or by use of sharp points. Maybe achieving CF is a simple as raising
D fugacity to the point of forcing D atoms to the surface of a highly
negatively charged needle point. This then opens the possibility of
surface or space fusion, and thus the elimination of the ash disposal
problem.
Hmmm... this is starting to sound like Claytor's negative wire thing.
He simply loads the wire from the vacuum side in gas mode. The
electron fugacity idea provides a reason and a means to really soup
up Claytor's approach.
