Nuclear Fusion’s New Idea: An Off-the-Shelf Stellarator

Cars That Think

Fusion offers the prospect of a nearly limitless source of energy with no greenhouse gas emissions. And unlike conventional nuclear fission, fusion comes with no risk of meltdowns or weaponization, and no long-lived nuclear waste. Fusion reactions have powered the sun since it formed an estimated 4.6
