I can't find way to use distributors. I see no bonus in any combination.
I tried:
energ-boost-dist-gen, energ-boost-dist-solar, dist-boost-gen, dist-boost-solar.
And see no effect in money, when distributor promises 100500%...
I check effect by assembling setup, check money, just remove distr. and only distr. and check money again to see any diff.
