How are other high temp fusion experiments going?
The Japanese, Chinese and Euros all have one, and maybe Russia is still experimenting?
A physicist named Sabine Hoffstadter(sp?) has a video on how far we really are from useful fusion energy. The recent reports of getting closer to 100% return on input energy do not count all of the inputs such as the energy to keep the magnetic field going or the losses when the heat of fusion is converted to electricity. What is currently reported as around 70% return is more like 1%.
