Is There a Liquid Fix for the Cloud’s Heavy Energy Footprint? - IEEE Spectrum: "Because liquids are denser than gases, they are a more efficient medium to transport and remove unwanted heat.
Yet direct liquid cooling is a rarity in the corporate data centers that run bank transactions and the cloud facilities that serve data to smartphones. Data centers consume more than 1 percent of the world’s electricity and about 2 percent of the electricity in the United States. A third or more of that expenditure is for cooling."
example: Asicminer’s 500-kilowatt computing system uses 97 percent less energy on cooling than if it employed a conventional method.
