It seems a bit ahead of available technology in that no one has been able to get net energy from any man made fusion reactor. Still who knows.
Looking at wikipedia it seems the highest Q - ratio of energy in to out in a real tokamak is 0.67 and a theoretical Q of 1.25 if you'd had better fuel. Apparently you need of about 5+ for the thing to run on its own where the heat is enough to run generators to power the tokamak, so we are a way off still.
Asking perplexity.ai when it says "it's unlikely that fusion will reach engineering breakeven before the 2040s or 2050s."
