About this project
What does Fusion Reactors add?

Fusion Reactor is a mod That adds nuclear fusion as a FE (Forge Energy) source for Tech modpack.
making a basic Tokamak:
To make a Tokamak you will need magnetized iron, to get magnetized iron, drop iron ingots on a lightning rod on a thunderstorm, when a lightning strike finally hits your iron now is magnetized and can atract near by items.
Electrolytic Cell and Getting Deuterium:
To make nuclear fusion you will need deuterium a Isotope of Hidrogen, It can be obtained by placing a Electrolytic Cell underwater and provide it with FE.
Fusing Deuterium
To achieve Fusion make a Basic Tokamak and supply it with Deuterium.
Cables and Pipes?
To use this mod you will need pipes for transfering Deuterium to the reactors and to transfering energy to the Electrolytic Cell.
This mod is in early stages, by now there is only a single reactor, in the future I plan on making multi block machines, and more variety on reactor type, maybe even anti-matter reactors who knows.
