What will fusion bring us?

Name: What will fusion bring us?
Uploaded: 2026-10-25

Description: Every second, the Sun fuses six hundred million tonnes of hydrogen into helium, and turns a little of the mass into light. On Earth, the heavy hydrogen in one litre of seawater could give as much energy as two barrels of oil, with no carbon. The catch: we must hold a plasma ten times hotter than the Sun's core. We are learning how.
