Theoretically, two lone nuclear reactors running on small pellets could power the entire planet, safely and cleanly. That’s the promise of nuclear fusion. So, why are we still relying on fossil fuels? For decades, scientists have viewed nuclear fusion as the Holy Grail for clean, abundant and sustainable power. Based on the same principle that powers the stars, including our own sun, a couple of nuclear reactors running on small pellets could power our planet without the risk of a catastrophic meltdown and zero greenhouse gas emissions. Still, we depend on fossil fuels for 80% of our energy needs . So, what’s stopping us from building these reactors everywhere? After all, scientists have been working on nuclear fusion technology since the 1950s and have always been optimistic that the final breakthrough is not far away. Yet, milestones have fallen time and again and now the running joke is that […]
