It doesn't say how many watts of power this machine would produce and what is the cost to produce per watt? It would be interesting to compare numbers and see if this machine would ever see mass production in next few decades.
As in, you want to partially disassemble and tweak the reactor regularly. Neutron activated metals will be radioactive enough after a while, no need to make things worse by adding tritium to the mix.
"The purpose of Wendelstein 7-X is to evaluate the main components of a future fusion reactor built using stellarator technology"
So I'm guessing it can't produce power as it is.
