Why Fusion Will Never Happen
12th March 2023
I like fusion, really. I’ve talked to some of luminaries that work in the field, they’re great people. I love the technology and the physics behind it.
But fusion as a power source is never going to happen. Not because it can’t, because it won’t. Because no matter how hard you try, it’s always going to cost more than the solutions we already have.
I suspect this mirrors similar arguments concerning railroads, steel ships, and various other technological tricks that were uneconomical when first developed but ultimately became so once associated technologies became sufficiently advanced. I expect that eventually we will have fusion power, although I don’t expect it any time soon–but I’d be very much surprised if it weren’t available a hundred years from now.
