Fusion power has been 30 years away for the last 50 year, lol. It is good that they are going back to a stellerator design since tokamaks do not work. Stellerator was one of the earliest fusion designs but we didn't have the computing power at the time to regulate the magnetic fields, we do now so it is moving forward. This version won't be net energy, but will hopefully get close enough to prove the concept.
When I saw the thread title, I thought it was in reference to sonoluminesence which is also called star in a jar (but no energy can be extracted). Here is a good link on the effect
https://en.wikipedia.org/wiki/SonoluminescenceIt is basically turning sound energy and converting it to light, and most people could build one in their garage with little expense. I built a really nice demo during undergrad for a class project.
