The Perpetual Idea Machine

Just wondering if a perpetual idea generating machine is feasible at all.Suppose one man's idea is an input to another man who generates more ideas from the input idea and so on..then it would lead to infinite chain of ideas..some useful..some useless...but since there are infinite ideas,there would be infinitely good ideas also.If such a machine can be made then,it would obviously be valued an infinite amount,unless all ideas are deemed to be of zero economic value.
But intuitively the idea of perpetual idea generation machine does not seem to be impossible... Invite your comments on this...
