Here's a render of the completed reactor: https://www.iter.org/doc/all/content/com/gallery/media/7%20-... Note human for size.

It's all completely bespoke scientific equipment hand made for this project only. The cryostat will be the largest stainless steel vacuum vessel ever made-- all welded by hand.

After welding, a substantial number of in-vessel components have to be installed by threading them through access ports, which is also quite a task: https://www.youtube.com/watch?v=pt70mO2nQac

Here's a similar picture for SPARC from wikipedia: https://upload.wikimedia.org/wikipedia/commons/thumb/7/74/SP...

It still need a lot of the (same) support infrastructure. Plus ARC will be bigger than SPARC.

That said building the first is a lot harder than scaling it up.

I believe SPARC is a magnet demo, so it won't have tritium breeding blankets like ITER. It also has a shorter pulse time, 10 seconds vs 1000.

(That's right. ITER, which will cost more than $65 billion and take decades to build, can't run continuously!)

Nor ever produce so much as one solitary erg to flash an LED.

You do seem to be going on quite the hatefest of Fusion, but continue to add nothing to the conversation, including sources of information. So how much energy is in an erg?

3000 ergs is enough to flash an LED.

When you have no turbine or any other means to extract power from a heat source, none gets extracted. Do you need a source for that?

That will become a level in an FPS game for sure.

Lol, I have the same though. They'll probably need to make the equipment a little sparser though, because it gets super crowded once everything is installed. Those cut-aways don't show all the detail.
