So my idea is as follows: There should be layered research, it should be possible to research a new research bench after researching everything currently in the game, the new bench can be placed directly over the old bench to "Upgrade" it, this would unlock the ability to research more stuff, including more benches, there could also be topic specific benches such as hydroponics research benches giving faster, higher yield crops, maybe even the ability to make a kitchen and cook meals that satisfy your colonists. the other part of my idea is that there could be a higher layer bench that allows for nuclear research, it would unlock fission and this reactor would be huge, 15x15 and would produce massive amounts of power, however it would have to be built is a new type of wall that takes lots of metal but is "Radiation proof" it would also require an airlock made with the "Radiation wall" and "Radiation doors", in this airlock there would need to be at least one "Radiation suit Rack" with a "radiation suit" on it and one "Radiation scrubber" that colonists automatically use when leaving the reactor, colonists would automatically put on the suit before entering and would not enter without it, wandering colonists would not enter also. the reactor could be right clicked and would be able to be turned on/off and "Fed" uranium, the next layer of bench would unlock better radiation equipment, after that there would be a fusion reactor that requires a similar setup, it would produce more power and require less Uranium, however it would cost nigh on 1,000 metal. the reactors would produce "Radioactive waste" this would have to be disposed of in a "Dematerializer" this would turn it into "Atomic matter" that could be used in a "Materializer", this would turn the "Atomic Matter" into metal or food at a ratio of something along the lines of 100 "Atomic Matter" to 1 food/metal. you would only get 1-4 "Atomic Matter" from each "Radioactive waste" and would get 1 "Radioactive waste" from each uranium you "Fed" to the reactors, the Fission reactor would take 1 uranium per in game day and the Fusion reactor would take 1 uranium per 2 in game days, a colonist would automatically feed the reactor if you click on them and tick the option "Feed Reactors" bound to the "F" key. there could also be a "robotics research bench" that allows you to build AI colonists that can take more damage, are 90% accurate with any weapon and don't need a radiation suit to enter a reactor however they still use the "Radiation Scrubber". these robots would need to have "Recharge Stations" that they can plug into whenever their health or power is low, at 10% power they will drop what they are doing and go to recharge.
