may or may not work by 2050

Ah, fusion power, always 20-30 years away.... for the last 30-40 years, still 20-30 years away.

There's a reason for that. They're pursuing a design that may work in the long run while forgoing every other method of producing nuclear fusion. At long last private industry is developing alternative solutions. And surprise, it's not a tokamak like every government funded organization is working on. Count on Lockheed-Martin to produce the first commercially viable fusion reactor. They've probably known how to do it for decades.

Nuclear energy is released when heavy nuclei are broken or when light nuclei are crushed together into new elements. The first is called fission, and this is how the atom bombs and nuclear reactors work. Fission is dangerous and it produces radioactive waste. Fusion can be done safely, and it creates only hydrogen and water.

Nuclear fusion powers the stars and it needs star-like conditions to work. A fusion reactor needs powerful, correctly shaped magnetic fields to safely maintain star-like conditions. So far, the energy-in to power those magnets is greater than the energy-out from fusion.

A breakthrough in low-energy electromagnets promises to make the energy-in less than the energy-out.

If fusion became viable, it would transform the world

If sci-fi movies serve me well this will end badly.

I will allow us to have fusion power in thirty years. Then again, everything in the field of fusion power will give us fusion power in thirty years....
