so the plasma reactor coud be build from some parts like chambers a new block. It will make a way more energy then a nuclear. But you need to suplly it with Hydrogen cell which you exctract from water. And then you will need it to fill the cells with him.
When you build it you will need to start it first, but for start you will need a lot of power.And then yo will need it to have enough Hydrogen cells places in the reactor(can it looks similir like nucelear system).
And if it si possible to make it some cool efectes. And the reactor will have to be build with more blocks.Like some part which you will have to place in correct places around the plasma reactor. Just suggestion.
And recipe? Hm i dont know yet. Just making suggestion. for reactor somthing like this
for chambers like this.
So have fun.
