Using a "chemical refinery" (SS1 p.19) to crack it back, an SM+x system should process one SM+x tank in 3 hours (if x is odd) or 3h20m (if x is even) for one power point. This is VERY surprising because according to SS1 p.20 a fuel cell produces 12 PPh (Power Point hours) per fuel tank at TL7, 24 PPh/tank at TL8, 48 PPh/tank at TL9 and 96 PPh/tank at TL10+ (an MHD turbine has the same efficiencys at TL9 and TL10+). That's an energy output that is 4 to 32 times the energy input! What ever happened to TANSTAAFL?

Since S7 solved factories by saying days not hours, would mining/refining be solved by something like output/50 per hr, cost of system /10. Then upping output and cost for each TL to 10, eg TL8 CF+2 +10% output; TL9 CF+4 +25% output; TL10 CF+9 +50% output.
Put simply, instead of output per hour, output per 48hrs at TL7, to per 36hrs at TL10.
Although, if the numbers in mining/refining are right, that'd make all the power systems wrong (brain melting)
