The Holy Grail of Energy Generation Might Finally Be Within Our Grasp

If you’ve ever been outside during the day, you’ve seen a fusion reactor—though you’re not supposed to stare directly at it. The sun is our fusion reactor in the sky. It’s constantly fusing hydrogen atoms to create helium, and this process generates a massive amount of energy, which produces the light and heat that make…
