Far from my specialist topic. But ...
Coz that's what the experts say.
Higher energy levels.
Hotter.
More ..

Artemis project. Excellent You'll be sorry ...

much use

Almost useful at low technical level

Slideshow.
You'll be sorry again ...

This team has one running.
Efficiency is 'a bit low" [tm]

Y don't buy no ugly slideshow (with many "images removed for
copyright reasons" )
FWIW Says reason Chinese want to do lunar access if for He3
mining.

Fusion in general is "hard". Nature can do it with large masses and
the assistance of gravity working for free. It doesn't seem to scale
down very well to our levels. IMHO I don't think it will.

Of the references I posted on He3 fusion and lunar Helium 3,
this one ( a "slideshow") makes the best compact
presentation of what is hoped for from it.
