I hate to see things go to waste. Having been in the computer field since 1976, I view CPU power as very valuable. SETI@home was the 1st practical way to put some of it to use when I was not using it. I've been running it ever since.
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.
