By sacrificing wall cooling, you can make fusion fuel cleaner.

A fusion reactor wall, like a sponge, soaks up particles, keeping the fuel clean. But it heats up to colossal temperatures in the process. Physicists have figured out how to trap impurities in a corner and distribute heat—a key step toward clean stellar energy on Earth.

🎯 A single glass of water contains enough fusion energy to power a home with heat and electricity for an entire year.

🎬 In the movie 'Spider-Man 2,' Doctor Octavius launches an artificial sun—a fusion reactor that spirals out of control. The plasma containment problem that scientists are tackling today becomes a catastrophe there.
