How these Villanova researchers are making data centers more energy efficient

Data centers — both the big server farms that house “The Cloud” and the small systems storing company data — use over two percent of the nation’s power. According to a recent report on 2013, that’s enough electricity to run all of New York City’s households twice over.

A team of researchers from Villanova University is working to chip away at that figure, by capturing the heat that servers spit out and turning it into electricity.
