5 metric tons of gold created per GWh of electricity

per GW. 5000kg over whole year of 1gw reactor going almost continuous. While there is no theoretical possiblity of creating economically viable fusion energy, a minimum reactor size would be 10gw. Needs 1gw of backup fusion to provide stable power input, and make the deuterium.

$500M/gw in gold revenue could make a difference in the economics. If fusion cost 2x what fission costs per gw, ($30/w) then it would make back its cost in gold only over 60 years, @$100/gram.
