Basically the same idea as compact solars, but applied to generators. Mainly intended for servers, and people who want to use generator power but don't want a giant wall of them to meet their production demands.
It would also be nice if a small buff to eu produced could be applied, to help buff generators a smidgeon. (something small, like a 5% buff for the lowest tier, increasing by an additional 5% per tier increase)
Also, it would be nice to change the automation sides so that all sides input into the burn slot, with the battery charging slot either being removed entirely or becoming manual-only.
As for the actual crafting recipes;
G = generator (a number beside it is its tier)
L = LV Transformer
M = MV Transformer
U = Transformer Upgrade
H = HV Transformer
LV Generator:
. G .
G L G
Generates at 32 eu/p (I really don't think the added 2 eu/t matters too much, and it helps with stepping up the voltage ladder)
MV Generator:
. G1 .
G1MG1
. G1 .
Generates at 128 eu/p
HV Generator:
. G2 .
G2 U G2
. G2 .
Generates at 512 eu/p
And I'm sure you can guess the last one.
Also, maybe another addon which does the same for the Gregtech generators? Although, without the extra eu, since those generators already buff their fuels.
