This is an incredible achievement but there are strong reasons to suspect that stellarators are not and will never be plausible candidates for energy generation. For some more experimental or perhaps military tasks, it's viable.
Why do you think this? Also, suggesting only the military should use it suggests it is stellarators are well suited for energy weapons versus powering homes/industry, which is also curious, as energy weapons need huge impulse amounts of power, not power that is constantly available and ramps slowly by comparison.
