Boulder's National Center for Atmospheric Research about to get shiny new [coal-powered?] supercomputers - Denver News

Although NCAR's headquarters will stay in Boulder, that site had run out of room, so the new center is in Cheyenne [Wyoming]. "These systems, as they've gotten more and more powerful, they require a lot of energy to run and keep cool," explains Krista Laursen, NCAR-Wyoming Supercomputing Center project manager. "We were really at the point where the infrastructure at the Mesa site was maxed out." And because the Mesa lab is in an "environmentally sensitive" area, NCAR was simply not able to get enough power to meet its needs without new construction. The existing infrastructure at the Mesa lab will still be used, she says -- just for different purposes.

In most supercomputing centers, that heat would get whisked away essentially by giant air-conditioners; in Wyoming, NCAR plans to use Wyoming's wind and cold to do the air-conditioning job. The center will also capture the heat generated by the computers to warm user-occupied areas.
