The early generator for GT is the steam turbine. After you go through the bronze age, you build it to get EU from your steam boilers.
Thanks for the quick response.
I tried the steam turbine, and I couldn't figure out how to connect it to my IC2 machines. Also, it exploded.
I've got an ordinary IC2 generator too, and it won't connect to GT machines. Any help with these issues would be appreciated.
Unrelated to this, my Railcraft steam turbine won't run, and I'm going to go find something to blow up until I feel better.
