Nerd time!
I am playing with RealFuels and was frustrated that fuel cells aren't changed. So, I thought about converting generic Fuel Cell Arrays into proper H2+O2 fuel cells (and CH4+O2, CH3OH+O2 and C2H5OH+O2 after that). Since I didn't want to make fuel consumption and energy generation purely arbitrary, I started some calculations. The biggest struggle for me was the amount of ElectricCharge that needed to be generated, but luckily KPBS has Elektron Container unit, which was a great help.
Another help was this thread:
So, assuming that Unit of "ElectricCharge" is indeed equals 113 joules, we now have this equations:
As you can see, Elektron container is super effective, having so negligible losses that they can be ignored! Oops!
