In just 5 to 10 years from now fusion will be commercially viable ... no this time it’s different, really, we know so much more than we did the last time we predicted fusion would be ready, which was 10 years ago, or the 10 before that .... but this time we are right.
Commercial fusion power is just 10 years away and will always be ten years away as long as scientists and engineers can suck money out of the rest of us to keep the project going.
