Re: Remote minning
Sadly remote mining decreases the value of the planet/asteroid by 1 percentage point PER robominer. So with fifteen robos on one battlestation it takes only ten turns to suck the world dry.
Another drawback is maintenance for the battlestation. It will stay the same amount, while return from the mined planet will decrease with its value.
It's not possible to mine a colonized planet.
In total I give the battle station mining project no positive business report. Bad return on investment. You have to build the thing first, then after sucking the planet dry (or even sooner when maintenance outweihgs return) you'll have to scrap it losing two thirds of your investment.
For a battlestation with 15 robominers II:
Cost: Battlestation: 18 kt
maintenance(10 turns) 35 kt
---------
53 kt
Scrap_Value of Base 18kT * 0.3 = 5.400
Incomeformula: (Planet_Value / Number_Robominers) * (Robominer_Return * Number_Robominers) * (Planet_Value / 100 / 2)
( with (Planet_Value / 100 / 2) being the average mining value because of the decreasing Planet_Value )
For a Planet_Value of 150% and 15 Robominers II with a return of 700 each:
150/15 * 700*15 * 150/100/2 = 10 turns * 10.500/turn * 0,75 = 78.750
For a Planet_Value of 120
120/15 * 700*15 * 120/100/2 = 8 * 10.500 * 0,6 = 50.400
For P_V of 105 you only get 38.587,5
Totals:
P_V 150%: 78.750 - 53.000 + 5.400 = 31150
P_V 120%: 50.400 - 53.000 + 5.400 = 2.800
P_V 105%: 38.588 - 53.000 + 5.400 = -9012
(Sorry, I used German notation: thousands point and decimal comma)
So in the end you'll be way better off with Heavy or Medium Satellites. Less maintenance cost plus you can relocate the sats after one location is out of minerals.
