Google throws open doors to its top-secret data center
It's a shame that heat is just dumped outside most of the time.EDIT:The article talks about Google's impressive technical achievements.  But there's a lot of energy that's wasted in industry.  I don't mean "used inefficiently" (although that's bad too); I mean actually wasted.I used to work at a tiny electronic sub-contracting factory. The morning shift would arrive, turn on the air compressor (2 KW), the reflow ovens (10 KW and 12 KW); and the other machines (about 7 KW).But they'd do that even if the machines were not going to be running.  All these KW were being used for no reason at all.  And the machines are pretty inefficient anyway.  (One of the owners thought powered machines looked more impressive.  Energy costs were included in the rent so there was no incentive to think about when the machines were on or off.  )Counting that waste across all the tiny factories in the world, and including all the waste in offices - it's quite a lot.
