It's a little science+fiction, but it's anyway a great reading.
He states that:
"(...) Berkeley astronomer Don Goldsmith reminds us that the earth receives about one billionth of the suns energy, and that humans utilize about one millionth of that. So we consume about one million billionth of the suns total energy. At present, our entire planetary energy production is about 10 billion billion ergs per second."
and also, he suggests that we have to search for a combination of a star and a planet with great infrared emissions:
"Eventually, after several thousand years, a Type I civilization will exhaust the power of a planet, and will derive their energy by consuming the entire output of their suns energy, or roughly a billion trillion trillion ergs per second. With their energy output comparable to that of a small star, they should be visible from space. Dyson has proposed that a Type II civilization may even build a gigantic sphere around their star to more efficiently utilize its total energy output . Even if they try to conceal their existence, they must, by the Second Law of Thermodynamics, emit waste heat. From outer space, their planet may glow like a Christmas tree ornament. Dyson has even proposed looking specifically for infrared emissions (rather than radio and TV) to identify these Type II civilizations."
Finally from the original article we see a theory i want to add to this reasoning:
"One possibility is that Wasp-18, a sunlike, medium-sized star, is a thousand times less energetic than would be expected. That would mean it produces much less friction on the planet than normal."
Why this star has a thousand times less energy than it should have?
The described model is used on some open source projects like Hyperic, Zenoss, Groundwork, Mindtouch and more coming.
