While I was waiting to fold space and journey to a good system to sell my platinum, it occured to me that engineers provide very little in the way of modifying mining equipment. Yes, you can lightweight, reinforce or shield your limpet controllers... but what about engineering said controllers to program and use more limpets? Or lasers that extract elements faster? Or seismic charges that only go off when you choose or perhaps be more powerful? How about an abrasion blaster that, instead of blasting, uses a limpet to pull exposed fragments from your 'sploded rock?
Perhaps I'll buy a planet and a base and set up shop myself.
My invitation requirements would be modest: 100 each of weapons inventory, chemical inventory and digital designs.
