1. Fusion reactors are still a long way (probably many decades) from becoming commercial. Even the experimental methods (including Tokamaks) have not achieved a true “break even” for any major length of time, let alone for a time that is commerecially viable. (Break even is when the energy out of the fusion reaction equals the energy it takes to heat up the fusion materials).

   A physicist acquaintance of mine who worked on such projects once speculated; in order to become commercially viable a fusion reactor would have to be so large, that only one would be required to power an entire country the size of the United States.

   The small Tokamaks you cite probably won’t work unless some new technology is invented to make them work.
