Sorry to keep bringing this up, but I'd really like to know what you think of this idea.
What do you think about the idea of being able to scale up rail-gun components (capacitors, launch-velocity, and caliber) like you can with sensors with technology only increasing efficiency?
As it is, only missiles have any meaningful customization option.
You can already change caliber, launch velocity, and capacitor charge rate based on tech. IIRC Steve plans on eventually adding spinal railguns as well. In the suggestion thread (since it didn't seem to belong here) I did suggest maybe being able to dedicate tonnage to extra capacitors, though. So that if, say, a laser took 8 power to fire, instead of storing 8 power you could have it be larger but store 16 power and be able to fire twice in successive increments before having to stop to recharge.
Let's say the laser takes 8 and charges 3 power per 5 seconds. Normally it would work like:
5 seconds: Fires, 0/8
10 seconds: Charges 3, 3/8
15 seconds: Charges 3, 6/8
20 seconds: Charges 2, Fires, 0/8
25 seconds: Charging, 3/8
With extra capacitor, it could look like
5 seconds: Fires, 8/16
10 seconds: Charges 3, Fires, 3/16
15 seconds: Charges 3, 6/16
20 seconds: Charges 3, Fires, 1/16
25 seconds: Charges 3, 4/16
