I remember back in the ECL mainframe days the waste heat was used to 
heat the computer center. When IBM announced a new series with much 
lower power consumption we proposed a spoof commercial with a bunch of 
people huddled around their new mainframe discussing doubling their 
compute power to get enough heat.

My research advisor was telling us when he used an IBM 650 (tube based!) 
in Montana they had a low heating bill in the winter, but the summer air 
conditioning bill was high.
