So we all know forestry and how it works with both IC2 and BC3/2 so here's my idea!
There is an energy bee (Not from hives, but from breeding an industrious bee next to an MFSU), this bee (While working) produces EU (If you got the EU energy bee) if the apiary is placed next to an engine then the bee will produce MJ!
The flowers for the bees are normal flowers (Not sure if that should be that)
So what do you think?
