20 blocks machine capable of powering portal lowering oort stones per second from 1 portal by (connected portals conduit number divided by 3) with minimum oort stones required = 1. Would link to portal the same way spark is linked to machines.
5 blocks portal machines booster which would allow to portal machine to connect to additional portal. Require connection to portal machine, require 300 power of every gem type.
Another 7 blocks advanced booster machine machine which would allow portal of size of 3 or more conduits work the same way as 1 size bigger, require connection to portal machine, require 600 power of each gem type.
Another 10 blocks machine allowing blinksec port requirement to be lowered by 20%. Require 1000 power of each gem type.
Additional machines could be linked to portal machine using the same connection as spark.
Edit:
Would give huge builds good reason to exist, would also promote big hubs and make bigger conduit count a bit more affordable.
