- The United States National Ignition Facility (NIF) made a breakthrough in reproducing the power source of the stars.
- The experiment smashed its own 2018 record for energy released from nuclear fusion reactions 23 times over.
- 70% of the laser energy put in was released as nuclear energy.
- Fusion takes small atoms and combines them to forge larger atoms.
- Fusion doesn't produce carbon dioxide or long-lived radioactive waste.
- The fuel it requires - two types of hydrogen known as deuterium and tritium - is plentiful enough to last for at least thousands of years.
- The NIF's breakthrough is about demonstrating the principle only, and the total amount of energy generated is not very impressive.
- Many recent advances have been made with a different type of fusion device, the tokamak.
- The world's largest ever magnetic fusion machine, Iter, is under construction in the south of France.
- Alternative designs are also being explored, including an advanced tokamak with an innovative spherical geometry and "stellarators".
