NSA@home is a fast FPGA-based SHA-1 and MD5 bruteforce cracker. It is capable of searching the full 8-character keyspace (from a 64-character set) in about a day in the current configuration for 800 hashes concurrently, using about 240W of power. This performance is equivalent to over 1500 Athlon FX-60 CPUs, which would take about 250kW.
So much for Decius's and Dan's project...
