errr, 180 million degrees? how is that even possible?

"Power plants have never used this process because it is extremely difficult, requiring temperatures over 180 million degrees Fahrenheit and immense amounts of pressure and energy, according to the International Atomic Energy Agency. As such, there are mixed feelings on whether CFS' plan will be sustainable in the long run, especially with green technology on a constant trajectory of change.'

That temperature is in the ballpark. The fusion reactor uses very strong magnetic fields to keep the extremely hot plasma away from the reactor walls. The temperature at the center of the sun is about 27 million degrees Fahrenheit.

The plasma in Commonwealth Fusion's reactor will reach a temperature of 100 million degrees Fahrenheit.
