I've wondered about this for some time, and didn't know if it was being
done. (I posted the thought on a forum or two and the thought was
dismissed).

My own take on the idea (cw emissions from modest sources) might be why,
but to me it's still an interesting idea.. How powerful do the pulses have
to be? Could we detect CW? There is one source of CW that we might easily
look for. Amateur and professional astronomers have both used lasers to
guide scopes, and if the laser is tracking a star, and pointing at it,
might some pulses be detected as a constant train? Especially in the case
of copper vapour lasers, which make small highly intense pulses
continuously. One thing about a planet full of people with lasers is that
there might always be something pointing from one star to another, so might
it be just a case of analysing the stars' light a bit more closely?

I seriously doubt if anyone who has the power to communicate between star
systems would use electromagnetic radiation to do it. What's the status
on gravity waves these days? How about quantum black holes? ;-)

Thanks,
Rich
