← SETI Allen array mothballed for want of £1.5 million

I agree that we should be spending more on spectroscopic studies of planets around other stars. These could both look for signs of life, and signs of intelligent life. I wonder what is the comparison of energy (and thus likelihood of being observed) of leaked radio and TV broadcasts from the earth in relation to the energy of the transmission and emission spectra of both life molecules and intelligent life molecules (ie pollution) of sunlight passing through our atmosphere at the edge of the earths disk. I bet its many millions, billions, or more times stronger, thus much more likely to be observable to aliens than our weak(and generally uninteresting) broadcasts. The reverse of this is where we should be focusing our observations. I still think we should also look hard in the broadcast frequencies like SETI does now.
