Just gonna steal these links from JWZ: Electricity, Poop, and That Bastard Edison:
- San Francisco's secret DC grid, on why San Francisco still has a large PG&E run 250v direct current grid.
- San Francisco's combined sewers. On a sewer and stormwater system that was largely abandoned (as JWZ notes) "... some time between the Romans and the London cholera die-offs in the 1800s."
- A rare look at the tunnels under San Francisco. For you urban-ex people.
