I'm 26 and have a few xtra computers lying around. Though I'd crank this up again (put it on all my lab comps back in college) and see how many hrs I could acumulate. Pretty sweet stuff...
Thoughts about SETI and SETI@home
I'm sure there is something out there somewhere, but it's a big place to look. Projects like this with distributed processing like this will really help out, some people may not want to donate money but processing time is free!
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.
