Thoughts about SETI and SETI@home
I believe SETI is an excellent project that allows unused CPU time to be used in a productive manner. I hope that SETI will be around for years to come.
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.
