In an effort to cut down on computer server system-based electricity bills and carbon emissions Timothy Shedd, an associate professor of mechanical engineering at University of Wisconsin-Madison, has developed a computer cooling system that claims to be 10 times more efficient than the air conditioning that are currently used in the university’s server rooms. The invention is now at a stage where it can be spun-off and commercialised.

Cooling costs at server farms are racking up annual bills nearing $2bn,…
