I run SETI@home because I have spare bandwidth on my computer, and
believe that it is a worthwhile project. We might not find ET, but
we will never find them if we don't look.
SETI@home and Astropulse are funded by grants from the National Science Foundation, NASA, and donations from SETI@home volunteers. AstroPulse is funded in part by the NSF through grant AST-0307956.
