Frequently Asked Questions

How does fusion work?

Fusion works by pressing hydrogen atoms into each other with such force that they combine into helium, releasing enormous amounts of energy and heat. Unlike other nuclear reactions, it doesn't create radioactive waste.

What is nuclear fusion?

Scientists around the world have been studying nuclear fusion for decades, hoping to recreate it with a new source that provides limitless, carbon-free energy – without the nuclear waste created by current nuclear reactors. Fusion projects mainly use the elements deuterium and tritium – both of which are isotopes of hydrogen.

What is the difference between fusion and fission?

Whereas fusion fuses two or more atoms together, fission is the opposite; it is the process of splitting a larger atom into two or more smaller ones. Nuclear fission is the kind of energy that powers nuclear reactors around the world today. Like fusion, the heat created from splitting atoms is also used to generate energy.

What is uncontrolled fusion?

But after December's breakthrough, we were invited to tour the lab and meet the team that brought star power down to Earth. Uncontrolled fusion is easy--mastered so long ago the films are in black and white. Fusion is what a hydrogen bomb does, releasing energy by forcing atoms of hydrogen to fuse together.
