"The infrastructure of a large data center poses two main problems: You need to find a way to reliably power all those servers, and you need to figure out a way to deal with the heat those servers put off. Syracuse University and the University of Toledo are experimenting with one gadget to solve both problems. Small power units that run on natural gas, called microturbines, provide reliable DC power separate from the utility grid, and their heat output can paradoxically be harnessed to cool the servers and transmit the heat to other buildings on campus."
