France has upped the ante in the quest for fusion power by maintaining a plasma reaction for over 22 minutes – a new record. The milestone was reached on February 12 at the Commissariat à l'énergie atomique et aux énergies alternatives (CEA) WEST Tokamak reactor.
It was about 1800 years between the first steam engine and a practical steam engine. I’m sorry that one or two generations is too long for you.
TIL. That sucks.
Well, there were a lot of fundamental steps that had to be completed first, not least of which was a high pressure vessel. This all took a lot of materials science, advancement in seemingly unrelated fields, etc., etc. Not unlike fusion technology… The difference is we have 2000 years more advancement than they had when they invented the steam engine.
