Topic: Buildable Accelerators
I think it would compliment the terraforming system nicely and be an interesting addition to gamma construction. The mechanics would likely have to involve some sort of linking between the different "pillars" to make them evenly spaced like they are in alpha. I'm not sure how they would be powered, if they had to be at all, but they should definitely be destructible to give a sense of disrupting enemy supply lines in times of war. The amount of the speed boost given might even be dependent on the tech level of the structure or the amount of energy supplied.
