This is not too important was just wondering if there is a limit on how many neutron collectors one person can have per island.
The only incidents where we put a limit on how many machines/anything you can have is if it causes lag. I've seen bases with quite a bit of those neutron collectors so you should be fine, just know that like anything else that causes lag, if your setup for any reason makes the TPS drop significantly, you will asked to decrease the number of machines. I think you should be fine though! Just keep that in mind when building, better to build with lag in mind than to have your setup taken down! -Tuff
