We have not yet figured out how to make fusion work yet. A lot of money and scientific effort is being spent to find out. We aren't talking about things that are 10 years away, we're talking about research that has succeeded being shared. But as soon as someone does figure out fusion (ITER looks good) and publishes, everyone will know, and everyone will have it.
