So you're saying, for example, that after plowing how many billions into fusion research, when they finally crack it and can produce continents-worth of power from pennies worth of sea water, they won't actually start giving electricity away for free? Even though we've all collectively 'invested' in it through our taxes for decades?

Isaac Newton spent more time turning lead into gold than mathematics. Time & money doesn't make dumb ideas good ones.

Bread needs water, flour, AND yeast to rise. Ain't gonna do much without all three.

And of course Sir Isaac found time to fit alchemy and mathematics in between the daily activities of subsistence farming. Oh wait ..

Was he funded by an external agency for the purpose of turning lead into gold, or was it only his own interest/initiative?

Interestingly, Newton was "Master of the Mint" at the Royal Mint, which supplies all the nation's coinage.

> Newton became perhaps the best-known Master of the Mint upon the death of Thomas Neale in 1699, a position Newton held for the last 30 years of his life.

If he had been successful in turning lead into gold, he might have made his employer obsolete.

Flatbread is pretty tasty I hear.

It’s also the worst investment ever - if the same money was invested in solar farms and research, we could have actual world changing energy sources right now.

More money doesn't make the wind blow more often. And there's only.so much capital that can be spent on material science before you hit a limit on the rate of improvement per unit time

An ironic comment, since fusion is the field depending on radical materials advances.

It doesn't work like a game of Civilization. Allocating resources to a research problem means you increase the social and material rewards for a certain type of person to work on a certain type of project. There is no guarantee of success or one to one allocation of resources. It's also not a zero-sum game when the money to one source of energy took away from another.

Also unlike a video game, the tech-tree dependencies are not obvious. We don't know in advance whether a tech will be a productive avenue of R&D, or if it depends on other unrelated advances in theory, material science, or computer modeling, or was actually completely unfeasible in the first place. I find wind power [1] as a case study representative, and we see similar stories for e.g. fusion, cancer research, AI

Unfortunately, nuclear fusion is physics research.

The unsaid part underlying physics research is "if you fund us, we promise to whip you up an atom bomb in 5 minutes if the Russians invade."

Physics research involves precisely zero cost effectiveness justifications.

99.9% is the government of the day thinking "if we do this,
