Engineering question: say you only had one generator with multiple places that needed power in real time. How to get power to them? Caveat: do it mechanically with no electricity. Low Tech Magazine brings you the Jerker Line System and the Stangenkunst, for all your post-apocalyptic / steam punk power distribution needs. Some are still in operation: Jerkerline Field wheel near Oil Springs Ontario (video), and Oklahoma (video).
Low-Tech Magazine and No-Tech Magazine have some fairly well written/illustrated articles about old and low technologies. The concept being, in a sustainable future due to environmental constraints, carbon taxes, Peak Oil, etc.. these old-school technologies might be used - in some places, in some form - instead of more energy intensive modern high technology. Trolly Canal Boats, Timbrel Vaulting (vs. steel and concrete), Bring Back the Horses (and the bicycle), Tile Stoves, Wind Powered Factories, Sneakernet, more.
