Does not appear to be and violates no law of physics.
The details in this post however are far afield of the 
reference I looked into.

Doesn't even look like anyone sees this as resulting in an even break 
even power balance.
Useful where one needs to generate neutron radiation however.

electrons.

-> Michiel,

-> "NANO" metres!  That is 10^9 times stronger than you thought.
