I would probably try to use it for some publicity. Prove if NSA can do some stuff, like breaking SSL certificate. Or you could recover perhaps 30% of your money by mining coins using spot instances. Other option is to donate CPU time to Folding@Home (cancer research) or other similar project. And finally my open-source project could use some stress testing :-). I have concurrent database engine. One of the way to catch concurrency issues, is to randomly insert delays around code, and hope it will trigger some rare race condition. I think single run will take a few years of CPU time :-)
