What currently impossible things would cheap fusion energy enable?
The return of an upwardly mobile middle class?
I do wonder if the collapse of middle class growth isn't thermodynamic. The countries that have enlarged their middle classes have done so by saying "fuck the environment, we're poor" and burning cheap coal with no scrubbers. It makes the air filthy and fuels climate change, but it is high energy return on energy invested (EROEI).
It's impossible to imagine all the things that would become possible if energy was unlimited, and cheap. We could build a fixed link to the moon, and mine the moon for minerals. The skies are the limit.
Heating roads to melt snow. Weather control. Desalination for farming use opening up farmland in deserts. Flood deserts with desalinated water and create new rainforests. Increase the spin of earth?
Fusion energy is very inefficient and I don't see it ever being very cheap. Fission energy could be a good choice for many areas, but the way the energy market works means that stuff like wind will always bid the lowest price to the market.
