Of course, 30 years is a very optimistic approach. I was, more or less, referring to the (theoretically) first successful break-even fusion generator whose model could (hopefully) be applied all around the world.
The first (planned-to-be) functional and break-even Fusion plant (DEMO) might
begin building DEMO in the early 2030s in order to operate it in the 2040s.Which means that
[it] will demonstrate industrial-scale fusion electricity by 2050.
"In 30 Years" does, by far, not mean that we would have instant and infinite energy from fusion reaction from that time on - but rather it's more like the first foundation stone laid ... although we're building a giant cathedral from now on. ;)
Okidooki! Thanks for the clarifications. The golden "50 years from now" seems again in order (I hear this since the 1990s :) )
