I spent 2 hours perfecting it and making it as dense as possible to the point the flywheels clip between one another, If you're unable to get power generation from them firstly check the kelp input because the topmost belt that runs horizontal will be the input for the 2 mechanical arms and secondly check to see if the flywheels broke since that appears to be an issue with create mod itself when you assemble builds that involve flywheels (simply just break them and replace them and it should work) | If you're looking for the current output for the power I believe it was around 32 thousand units (I think, I haven't messed with it recently because I built it last year so if there's any possibility of getting it fact checked that would be desirable)(NOTE: THIS ONLY WORKS FOR CREATE MOD ABOVE AND BEYOND (possibly))
