Why? So after you gain a bunch of resources, you never have to worry about energy in any way again, this isn't EE2 here.
EDIT: I see now that I was on the wrong page, and therefore got nina'd several times
Eh when i see little kids complain about this not being craft-able it just goes to show how lazy they are. on my small private server i placed one in the spawn to power the lights and the teleporters in doing so it only requires 1 battery box and a handful of mfsu's to make every thing work. i set it to 32 eu't and told it make 25k eu constantly. even for a spawn generator we feel its too Op for that.
