We often think of fusion power as the ultimate “holy grail” of clean, abundant energy—something scientists have chased for decades. But as I discuss in this brief segment from Innovation Café, there’s a bigger perspective we sometimes miss: every single energy source we use can be traced back to fusion reactions in the stars, one way or another. By stepping back and shifting our viewpoint, we see that the quest for fusion on Earth is really about localizing what the cosmos has been doing for eons.
