Let's take the "definition of gravity" discussion to Off-Topic and leave this thread for 0.14.0 feedback, thanks!
Dalas120 How are you testing power usage? That power usage for the small thruster should not be that low. I'm curious if there's a bug.
When I originally made the 3 original thrusters, cost and size were really the only way I could create tradeoffs between the different thruster sizes, which is why larger thrusters are less cost-efficient but more space-efficient than smaller thrusters. But now we have the ramp-up time, which creates a much more interesting trade-off. I'm thinking that maybe, at the very least, thruster cost should be directly proportional to thrust, making the tradeoff between surface area and ramp-up time? (Or if that's not enough, making larger thrusters more cost efficient.)
Which begs the question: Are small thrusters too cheap, or are standard-and-larger thrusters too expensive?
Another tradeoff I can make is in power consumption, making larger thrusters more power-efficient than smaller thrusters. (Right now power usage is supposed to be directly proportional to thrust, though @Dalas120's testing seems to indicate there might be a problem with the small thruster in that regard.)
