Fusion Power is speculative and experimental. I think it is reckless to assume that the fusion problem will be cracked, but I’m happy to estimate how much power fusion could deliver, if the problem is cracked.
But he only looks at DT and DD fusion. We’ll need to get pB11 into the next edition.
In any case, his conclusion is that, if cracked, Deterium based fusion offers plentiful sustainable energy for millions of years. The info graphic from this page is great for perspective on just how much energy in comparison to all other sources! And that’s just DD. How do we calculate pB11 for this info graphic?
