The cleanest baseload energy isn’t fusion. It’s already under your feet. Deep geothermal: 400°C rock exists everywhere on Earth. The physics is solved the only bottleneck is drilling cheap enough to reach 15km. Millimeter-wave drilling melts granite instead of grinding it. Crack that, and you get limitless, weather-independent power anywhere even under existing cities, reusing dead fossil plants’ grid connections. Fusion is a 30y bet, but deep geothermal is an engineering problem we can solve and start building right now.
