403s is about 7 minutes, so less than Wendelstein 7-X.
Apostrophes are already tricky for English as a first language, it must be hell for English as a second language speakers.
On the other hand it is reminiscent of a Georgian I met who used to be occupied with winding regular tire sized coils by hand, for over land transmission lines. This is chirurgical precision, literally hand-craft.
We do a lot of thinking with our hands. It stands to reason, metaphorically speaking, that Wendelstein is an experiment to gain hands on experience. Therein lies the difference to megalomanic projects that exceed initial estimates, eg. BER airport, which are a running gag by now.
Insolvency means the investment returned no profits so investors on those projects stopped paying. It likely doesn't mean that the cheques bounced on liabilities. And it obviously doesn't mean that investment in this space had to stop.
But that's exactly what it means:
All while not being able to properly simulate the outcome on a computer.
Stellarators are superior to tokamaks, so an energy-positive stellerator will be about 2 times smaller than a tokamak. But we're still talking about a building-sized vacuum chamber.
That's why for ITER it makes sense to go with a simpler design to de-risk the main objective: building a burning plasma laboratory.
