I looked at some stuff from FFS... Specifically, Solar Panels and a few other items. Probelm was, I couldn't draw even an acceptable abstraction of converting MW to EP. I found a few things in T20 that suggest that 1 EP = 10 MW... But I've also found a few tings that suggest the conversion is drastically different. I did however, using only T20 rules, reverse-engineer a few power plantsand drive trains to create what I felt was a fair wind-power and hydro-power plant design, and then built a whole bunch of different sizes. Not sure how useful they'd be, but if people want'em, I got'em...
