Centuries? Stay in your lane skipper.Fusion reaction requires a constant sustained core temperature in excess of 100 million degrees. the only way it has been achieved in a lab is by surrounding the reaction with basically a magnetic force field, and even then it's debatable if it produced more energy than it took to create the reaction.
We are centuries away from fusion being used to generate power
What they have already accomplished was unthinkable just a few years ago. Relax and celebrate the possibilities instead of being a d-bag. No one said they have it ready. If this happened two years ago Trump would have been taking credit for it. Nobody knows more about fusion than Donald J Trump.You do realize 100 million degrees is many times hotter than the core of the sun???
There are no materials on earth capable of withstanding the heat required to sustain a fusion reaction
