This is the DOE. They mainly work on nukes, and if they're experimenting with cloud computing, it's not because they're trying to do commercial or academic work into cloud computing, it's because they're trying to find powerful and cost-effective ways to get the computing horsepower they need to work on more nukes, just as when they work with supercomputers, it's not just because they're "Imagining what they can do with a Cray", it's because they're trying to solve problems that are really that big.
So, like, back off man, they're scientists!
Or don't back off,. because they're developing weapons as well as civilian power applications, but don't confuse tool-building with pork barrel.
