What is Fusion Energy?
When hydrogen isotopes (deuterium and tritium) nuclei collide with each other at ultrahigh speed, they combine (fuse) overcoming the repulsive force, and producing enormous amount of energy*.
* The fusion reaction of hydrogen isotopes (such as deuterium and tritium) using 1 gram of them (equivalent
to 5 balloons) produces the same amount of energy as burning 8 tons of oil (equivalent to 50 drums).

The magnetic field (magnetic field lines) necessary for plasma confinement is stably created only by electromagnetic coils
Plasma is stably confined for a long period of time
The output energy is constant, making it suitable for power generation

Plasma
A state (of matter) in which gas (such as hydrogen) is heated up to an extremely high temperature, and the nuclei (protons and neutrons) and electrons that make up atoms are broken apart. The central temperature is over 100 million degrees Celsius. The plasma is trapped around a magnetic field (magnetic field lines).
Helical Coils
A pair of electromagnetic coils in the shape of a double helix wound around a donut. A superconducting conductor is wound to generate a strong magnetic field (magnetic field lines) twisted into a helical shape by having a huge current.
