Two weeks ago, OpenStar Technologies achieved “first plasma”

“It’s the only fusion configuration that nature doesn’t want to destroy immediately at all times,” he said.

It seems like they are taking back from where the old LDX program was when it was cancelled.

Levitated dipoles have plenty of advantages, but their weakest point is that the floating coil must be cooled, charged and launched in position during each run and will last only as long as the coil charge last. Once the time is up reactor must be turned off, coil recharged, re-launched and reactor restarted.
Experimentally I think to remember that they reached up to few hours of self levitating time for the floating coil before needing recharge, but on the commercial reactor the time was going to be "few minutes" before needing recharge.
That of course would made a commercial reactor quite complicated to run.
I remember to read that one of the main reasons why they ultimately cut the funding to the LDX was also because there was no solution to this issue.
