I am dedicating some of my computing power to SETI@Home because I am a libertarian. This is a voluntary effort to support science rather than a coercive , tax supported, effort. Individuals need to take responsibility for supporting the research in which they have an interest.
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.
