  1. Anytime you hear "free energy" you know it's at least partly BS. Free as in the 'fuel' is free like a solar cell at best, solar cells as relatively cheap as they've become are far from free and this idea, if it works, won't be free either.

  2.  @mrnobody.4069  Solar can be free on the margin, it'll never be free, but eventually very cheap. It will always cost something significant to mfg, install, maintain and replace. I welcome fusion tech for eventual space travel utility say, but that's likely a century away. Also for the science and tech advancements in general. Seriously doubt it will ever compete with 'indirect fusion', aka., solar on Earth, simply due to capital cost. Unless one of the alternative long shot attempts succeeds, these tokomaks seem inherently extremely expensive.

  3. Ocean rising rate not very significantly changed in a century.
