[geeks] Memo to self: try not to destroy UPSs

The SmartUPS has a fan running 24/7 mounted directly over the heatsinks
to move air. That's not something they come from the factory with. I did
try to think this through. The idea is that, while almost certainly
overloaded, the Sine UPS carries most of the load until it fails, at which
point the smaller individual UPSs kick in. If my 3KWs were here, it'd be a
different story.

That's one thing I hadn't thought of lately: MOVs. Need to get some of
those into the mix. I have had a UPS destroy itself in my company; it
tried to set my passenger seat on fire!
