[sdiy] sniffing OT

Our "burn-in room" used to be used to burn in 2 or 3 UPS at the same time,
and I am talking 5 to 20kw units. There was a large bank of air cooled
thermal elements in one corner, and they kept the room at a toasty 60
degrees celcius. Great for days you got wet on the way to work. For the
really serious dissipation (50 - 200kw power conditioners) there were water
cooled units on the roof. The first time the water cooled units were tried
they were inside, and the resulting steam and condensation on the cold
factory roof resulted in a good "rain" soaking the work benches floor etc.
The guy doing that burn in was doing it over night and had shot of home for
something. When he left the water baths were full. When he got back, not
that long after, the elements were exposed and red, and the above soaking
had occurred :)
