A random question: My place was built with all the plumbing for a central-vac system that I have no intention of using ever. What alternative uses might I have, for this idle series of tubes? Right answers, speculative answers and hilariously wrong answers equally welcome.

@mhoye

- centralized air _filtration_ system

- pneumatic tube message delivery

- cable chase

- burrito distribution

- habitrail for a small population of hamsters

@brennen I've already sorted out my centralized air filtration situation, thankfully. Early in the pandemic I put a UV sterilizing light in the ductwork.
@mhoye i should probably add one of those somewhere, though a lot of my primary concerns are more in the way of wildfire smoke and the side effects of being near a major road than they are biological pathogens.
