And to be clear: we are not talking about funding, we are talking about the probable viability of hypotheses being studied in relation to being able to demonstrate Q=>1.

Tokamak Energy is featured in a short 3 min 34 s news clip by Channel 4 from UK. You get to see their current lab and tokamak. General Fusion is also briefly mentioned.

JET had already reached 64% of break-even back in 1997, before it had a robust enough physical structure to take a break-even load. Now that it's been completely refitted, it's only a matter of time before it achieves break-even.

Says that (as of last year) the plan was to run DT again in 2017.

they say that the plan is to produce 15 MW of fusion power in essentially steady state (5 s duration), which is better performance than the previous DT campaign where they achieved 16 MW transiently, but only 4 MW in steady-state. However, because they are using ~ 45 MW heating power (combined neutral beams, RF, and induction), this will only correspond to Q ~ 0.3.

I may be exposing my ignorance (hopefully not stupidity), but I seem to recall that the revived JET had a goal of reaching break even near the end of the current research run, ~ 2019. As such, could the quoted numbers above reflect an intermediate goal?

Also, there is some interesting numbers. If they are needing to increase heating power nearly 100% just to maintain the same output for 5 seconds instead of less than 1 second, it would seem to not be encouraging from a predictive standpoint. There would be no intervening improvement in confinement, and actually a significant decrease in effective confinement with longer term steady state goals (of 5 seconds vs less than a second).

Though, I guess a near 2 fold increase in input power yielding a ~ 3 fold increase in fusion power steady state is scaling in an eventual break even direction.

[quote/]"In the history of fusion research the year 1991 is particularly significant: on the 9th November a Preliminary Tritium Experiment achieved the world’s first controlled release of fusion power. Six years later, in 1997, another world record was achieved at JET: 16 mega watts of fusion power were produced from a total input power of 24 mega watts – a 65% ratio. This is equivalent to a release of 22 mega joules of energy. a total of 16 MW was measured for less than a second and 5 MW for 5 seconds."[/quote]
