About Magnesium Reactors
From mod.ioMagnesium Reactors
No Scripts, works on any platform.
Adds Magnesium Reactors that use Magnesium Powder as fuel. Includes vanilla and (if you have dlc) warfare 2 versions of reactors.
Magnesium-Air Fuel Cells are a thing we use today to generate power, there is no reason we lost that technology 100 years later.
Carefully balanced as a mid game power source.
Blocks take power cells and explosives instead of reactor comps and super computers.
Max powers: 0.5, 10 (instead of 14.75), 12 (instead of 15), and 150 (instead of 300)
If Ice takes shovels, Magnesium takes a handful and Uranium takes a pinch.
Great for mid-game. Awesome for mobile grids. Nice on planets where uranium may not be available.
Enjoy, let me know if you have any questions, or suggestions. It's possible I might adjust the balance a little in the future, but its unlikely to get any worse or drastically better.
