Fission vs Fusion.
Maybe we'll get the fusion figured out some day.
Fusion is always just 20 years away, but then maybe now only 15 years...
Fusion Energy Gets Ready to Shine—Finally https://www.wired.com/story/fusion-energy-iter-reactor-ready-to-shine/This Poloidal Field Coil Winding Facility (below) is one of 39 buildings on ITER's 445-acre campus. Since the isotopes creating the fusion energy will be 10 times hotter than the sun, two layers of magnetic coils ringing the machine will keep them caged within. That silver doughnut is a cryogenic chamber that will stress-test the coils.

"In 1988, engineers began designing the International Thermonuclear Experimental Reactor, now just ITER. Along the way, 35 nations have split the $23.7 billion price tag to construct its 10 million parts. Now, surrounded by vineyards in France's Saint-Paul-lès-Durance, the 25,000-ton machine is set to be flipped on in 2025."
"The isotopes butting heads will be deuterium and tritium. To get the atoms whipping around the inner chamber of the Russian-nesting-doll-like machine, a magnet will drive 15 million amperes of electricity through them. They'll also be zapped by 24 microwave generators and three semitruck-sized particle guns, until they reach 270 million degrees F and, avec optimisme, crash into each other, releasing heaps of energy. There's no guarantee ITER will achieve fusion by 2035, as scheduled."
I always find it amazing what people can build, 32 years and $23.7 billion blows me away.
