Re: scaling up is the answer?

i've come to believe that the tokomak fusion reactor is a technology that's destined to go straight from "experimental" to "obsolete" without ever stopping at "viable". (Much like Uber's business model.)

Solar cell and battery technology are both improving year on year. Currently it's viable for maybe 3% of consumers to go off-grid using this technology. In a couple of years, it'll be 6%. In a couple more, 10%. By 2030, something like 75%. And the tokomak still won't be viable even on an experimental level.

By the time it is working, all our power stations will be burning agricultural waste or methane and actively reducing pollution. Nobody will need a new, big, capital-intensive power station, no matter how clean it is.
