How hot runs a Farnsworth?Hirsch fusor?
Cold enough to not turn the garage into a pit of molten rock ;-)
Well, the baseline for "hot fusion" are stellar environments (our sun has
a core temperature of about 16 Million Kelvin) and the insides of Tokamaks
actually producing fusion reaction, also in the millions of Kelvins.
But the Farnsworth/Hirsch Fusor, while a useful tabletop source of
neutrons, cannot become a net energy source due to design inherent
losses.
The Polywell system looks potentially promising here ...
Kind regards,
