Modder brainstorming session

For the solar sail/ no movement for ships problem, all we have to do is add a "1-per ship" really efficient engine.
It would give 1mp, use 1 supply point.

so it would be a navigational thruster, used to orient the spacecraft, like a rudder on a sailboat! Even the cheapest solar panel would give you unlimited range!
