I have an idea to improve the nuclear power mechanics of this mod,
Rather than just Nuclear Fission, in the form of a nuclear reactor (which has brilliant game mechanics unto itself), I suggest the introduction of Nuclear Fusion as a truly end-game power source, with the introduction of components like electromagnets etc. (to be used in the construction of the Fusion Reactor block(s)) which require valuable items to create, such as many advanced circuits and energy crystals.
On start-up of powering this reactor, the energy produced could be exponential, i.e. initially it is similar to a reasonably well designed fission reactor, but then over a period of say 30-40 seconds it increases in energy production to being much more energy productive than any fission reactor. The reason for this will become apparent later in the post.
To power this reactor, rather than entering uranium, water and ice blocks (buckets of water, blocks of ice) could be used, and in return there could be an output of buckets where water is used, and (lending itself to another idea (air tanks)) oxygen for both ice and water. This Oxygen could then be allowed to dissipate or be used to fill (charge) air tanks which while filled (charged) allow the wearer the ability to breathe underwater.
Cooling solutions could be implemented similarly to the way it is done with the fission reactors, but another mechanic I thought of, to allow for improvements in efficiency, are the introduction of super-conductors (providing improved energy production at the cost of needing increased cooling to prevent damage), the introduction of lasers, which increase the speed at which the fusion reactor comes to full energy production. These and any other improvement items could be introduced to reactors similarly to how machines such as the Macerator takes upgrades. Or perhaps they could be added as full blocks that must adjoin the reactor.
What do you guys think?
