After so many years of hype around fusion it's hard to take press releases seriously. This bit at least offers some hope:
"The researchers have successfully tested the prototype’s ability to sustain a plasma efficiently, and as they further develop and expand the size of the device they can ramp up to higher-temperature plasma and get significant fusion power output."
Unfortunately they don't mention how long the plasma was sustained.
Hype is a double edged sword. Without it, nobody pays any attention and you can't raise money. With it, everyone ends up disappointed and you can't raise money. :)
