It looks like the United States Air Force needs some heavy research machinery at a low cost. Who do they turn to? The PlayStation 3, 300 of them to be exact.
The Air Force Research Laboratory is conducting a technology assessment of certain cell processors. The processors in the Sony PlayStation 3 are the only brand on the market that utilizes the specific cell processor characteristics needed for this program at an acceptable cost.
At this moment it is only a Request for Proposal, in which sellers will provide price quotes to the Air Force.
If you have 300 PS3's here is the RFP link.
