These are two older articles, but thought they might bear repeating given some of our current discussions. Sounds like a science fair project I wish I'd done as a kid! :)

How much power do aliens need?

If they're smart enough, they'd need only a watt to make ‘Contact’

And another interesting article by Seth Shostak:

Cheap Communication Schemes for ET

When it comes to signaling across space, power is paramount.

Nice reading Digger, thanks.

Hiya Alex and Ulli :)

I figure if i'm going to hang around here I'd better start pulling my weight and post some articles.

How cool would it be to do a targeted transmission for an elementary or high school science fair project? "Hey, Bobby... what's your project over there doing?" "Oh, I'm attempting to contact an alien civilization with a targeted, low-wattage pulse transmission." What a hoot.

Cheers,



Jim (Digger)

So the first thing ET hears from us is, "XBox Rulz!!!"

just found at the Seti Channel

What If Everybody Is Listening And Nobody Is Transmitting?

Whenever I present a public lecture on SETI, I can almost guarantee that the title of this article will be one of the questions I get from the audience. During our 1997-99 workshops on the next two decades of SETI research here at the SETI Institute, the workshop participants took the question of an active transmission strategy very seriously. The results of their deliberations have been published as SETI 2020: A Roadmap for the Search for Extraterrestrial Intelligence. They concluded that transmission is NOT an appropriate strategy, at least for the next two decades. Humans need to grow up first.

To understand this conclusion, it’s necessary to appreciate that there is a fundamental asymmetry in our current situation: we are a hundred-year-old technology in a ten-billion-year-old galaxy. At the workshops Harvard physicist Paul Horowitz summarized things very well; he said: "If it happens at all, there always has to be a first contact between two technological civilizations. Statistically, it is extremely unlikely that our fist contact with an ETI civilization will also be its first contact with an ETI civilization. Thus the advanced technology we detect will have experienced this type of encounter many times before. It already may have established a galactic protocol for information interchange, to which ab initio transmissions by Earth will have no chance of adhering. Thus we justify our asymmetrical listen only strategy by recognizing our asymmetrical position amongst galactic civilizations. We are among the very youngest!"

Hopefully 'they' are transmitting and we're listening in the right direction! Interesting articles--thanks for sharing, guys. I have to agree, Uli, at this point its better to receive than give even though that doesn't seem to follow conventional wisdom for the adage.
