Because I had some questions about the EU distribution rules and a thought about combining power sources.
One question regards step-down transformers. What is the official behaviour of a transformer when you've connected to multiple output faces? I get the impression from discussions that a transformer stepping down from 2048eu to 512eu would only output 512eu/t total across all faces, but I would have thought 512eu/t per face would be more in keeping with the rest of the mod. I get the impression this might be what happens anyway as I have one HV trans feeding four 512eu loads I think. I was running four MFR laser drill prechargers. Unfortunately the server admin got bored and reset the server so I can't easily confirm that.
Regarding power sources combining I think instead of allowing generators to combine indefinitely the summed output should be limited to the generator's tier, and to combine more generators would require a step-up transformer. That would make step-up transformers useful for more than just electric fences.
Variable output devices ought to have a slot for transformer upgrades, so if you don't upgrade then the power output per face is limited to the generator's tier
Other ideas: simplified cable losses: forget measuring length and just impose a fixed penalty each time cable is used at the incorrect tier.
Allow any un-insulated cable to be used at one tier higher than its insulated form, so bare iron wire could be used as a substitute for glass if you avoid standing too close.
