What are your thoughts on SPARC? I understand the magnets they are using are potentially much better for confinement than the ones ITER is planning on using, and with the advances in maintaining a plasma made by JET I think SPARC have a good chance of making a serious dent in the timelines.

I think that any opportunity we have to produce a sustained fusion reaction and rid ourselves of fossil fuels is worthwhile. Diversity in this field can only be a good thing. SPARC is a kind of tokamak correct? MIT usually has smart people working on things, im optimistic about fusion. Seems like the frequency of good news surrounding fusion tech has increased in the passed 10 years as well. Let's keep going. I'm a high school graduate so the highly technical discussions surrounding this is beyond me but articles like this one make it easier for me to understand where we're headed, and I love learning about this type of stuff.

Yep SPARC is a tokamak. It's about a tenth the size of ITER, but should get the same output because they have better superconductors. Tokamak output scales with the fourth power of magnetic field strength: double the field, 16X the output.

I think SPARC has a shot; they are designing for sustained fusion and with the work already done at JET and other tokamaks they will be starting with great data on how to manage plasma.
