There is an interesting note in the July-August issue of
American Scientist (vol. 87, page 314, 1999). It is about
"inertial electrostatic confinement" device for producing
neutrons. Not really "cold fusion" but ... They say that
such devices will soon be commercially available, and
give names of developers. Even Los Alamos National
Laboratory is involved.
Here is my way of understanding what the author tries
to explain. The device is an evacuated tube in which a
negatively charged spherical anode accelerates electrons
toward the central zone. A negative cloud of electrons
is formed and it attracts positively charged deuterium
or tritium ions. The ions oscillate near the center and
collide, sooner or later, to produce neutrons.
The approach is based on the Farnsworth's patent
from 1950's. Can somebody elaborate on this topic?
