- Fusion reactions occur when two atoms pull each other via nuclear force stronger than it can be pulled back from each other via electrostatic force.
- Atoms heavier than iron-56 will create an endothermic reaction, where heat will get sucked into the atom and requires energy to obtain that.
- However, atoms lighter than iron-56 will create an exothermic reaction, where heat will push out, allowing for easy obtainability of the energy.
- Therefore, we can use Hydrogen-1 due to it's low proton count and easy to obtain rarity.
- However, in order to create fusion, electrostatic force gets stronger as an atom gets closer to another atom.
- Therefore, heating these atoms to extremely high temperatures or accelerating them via a particle accelerator is what is used
- For fusion energy, we will be using heat. When we heat these atoms, it loses its electrons, causing a bare nucleus to exist, called ions. This is called ionization. When we do this, it creates a cloud of these ions which we call Plasma.
- Plasma is both electrically conducting and magnetically controlled, which is what is used by fusion reactors to contain the extremely hot particles. Then we just pipe this heat into water, then to a turbine, and so on and so forth.
- The problem that is presented with this idea is that it requires lots of energy to contain plasma due to its diamagnetic nature, in which it will reject external magnetic fields with its own internal magnetic field. For example, if you put two south magnets next to each other, they will in turn push each other back. This is the problem with fusion reactors.
