1. Because my computer is running 24/7 even if i don't use it, so I decided to spend his free capacity to Seti@Home
2. I think that sometime the way is the target, even if we will never find something, the Seti@Home Project started a new kind of world wide teamworking.
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.
