But on Earth, we need energy a lot quciker, so we use fuels that burn much quicker. Second, the temperature in the center of the sun is 10 million degrees.Tokamak are at 400 million degrees and focus fusion is at billions of degrees.

Thanks — that makes a lot of sense. I guess my intuition as to how hot it is inside the sun was the problem. It’s relatively cool in there, so the rate of fusion is actually much lower. Your answer explains why H-Bombs work also, they are probably highly concentrated deuterium or tritium which fuse much faster.
