Dan Wertheimer,a SETI researcher at the University of california in berkely, says,We're making incredible progress. The more computing power you have, the better job you can do looking for these signals.Capabilities have been doubling every year.One reason SETI's computing power has been increasing is a volunteer program started in 1999 called SETI@home,in which the computers of ordinary people around the world are used to analyze SETI data.
