@the_etrain I heard that this was no longer true, and some european experimental reactors work (and are just too small for practical usage because experimental).
But knowing microsoft, i would rather bet on them using some nice clean coal to supply energy to a non-sustainable fusion reactor.
@michaelgemar
Wow dude, that's a big ask about the "commercially viable". You'd have to factor in that who owns fossil fuel plants can prolong their usage, and that's commercially more viable.
As everyone knows, the market is populated by rational actors!
@admitsWrongIfProven @the_etrain It’s pretty easy build a device that will produce fusion reactions — the real challenge is to get more energy out than one puts in. As far as I know, no commercially viable reactor design has done that yet.
