In a way SBB is partially powered by hydro powerplants that can't be used for anything else: SBB has its own 16.7Hz grid because this is the train supply frequency. It's powered partially by sbb's hydro plants, partially by frequency converters (mostly rotating ones) from the grid, and has some amount of pumped storage. Alas, this update is about power bought from the grid, so it's exactly as you're saying.

@berkes

Science museum is nice (and when you have questions they search for a staff member who can answer then and sometimes you end up puzzling things out together).

Novelty Automation is a small arcade with largely social commentary games by Tim Hunkin.

@whitequark would your headmate perhaps be willing and able to give a pointer to a reasonable point to start reading about this?

@aeva yeah, the spectrum is pretty nice. It's easier to validate that with a diffraction grating (e.g. a CD).
