  1. Re:You nailed it! on Photo of First Extra-Solar Planet? · · Score: 1

    Um, no actually, how I found that out was in a BBC documentary series called The Planets. They had an episode on extrasolar planet detection, and two french scientists had found a way to access the chemistry of a planet by using the light of the star. At the time I thought it may be hard to do with the atmosphere there, and when I heard this, I figured what else could it be? Hubble wouldn't be capable of taking a direct photo of it, but is very good a spectroscopy.

    Why have them do the smashing carefully? If you want to learn about how real crowds act they have to be rough. Just through stuff everywhere in random directions, don't bother cutting it up. This would emulate the average drunk soccer hulligan....

  3. Re:Gasoline Fuel Cells on Boeing to Develop a Fuel Cell Powered Airplane · · Score: 1

    Is there any fuel that can be used in a closed loop that has a better efficiency than hydrogen and oxygen? I want to be able to plug my car into a power point to charge it up, not fill it with gas. Thanks,

    Um, no. That would be a methane fuel cell system. :-P

  5. Re:Which Fuel? on Boeing to Develop a Fuel Cell Powered Airplane · · Score: 2, Informative

    The good thing about hydrogen/oxygen is that it is easily rechargeable. You can hook it up in a closed loop, with the fuel cell taking 2H2 and O2, and converting it to 2 H2O. You can then take the resultant water to a storage tank, then during charging electrolsys splits the water back into Hydrogen and Oxygen. I'm not sure of any other fuel cell system that can do this.

  6. Building a Hydrogren Fuel Cell? Semi-OT on Boeing to Develop a Fuel Cell Powered Airplane · · Score: 2, Interesting

    I'm about to begin constructing an electric car, and instead of using batteries which are heavy and expensive, I've been thinking about building a hydrogen fuel cell. Anyone know of some good web pages about that? Thanks,

    No it wouldn't. Because a massive invasion force wouldn't have an atmosphere. They would be in a ship, or a fleet of ships.

    bah 7 cents a megabyte is cheap. How about 18.9 cents a megabyte, with a 3 GB flat rate limit, for all transfers in Australia. 3GB's over the line, total of both directions, then 18.9 cents a megabyte after that, in both directions.

    Yes, but what it proved was that the technique of detecting life worked. If you detect another world with similiar lifesigns, you can assume that carbon/water based life exists there.

  11. Re:Photo of First Extra-Solar Planet? on Photo of First Extra-Solar Planet? · · Score: 3, Interesting

    That would prove that it is a planet. There is also a new technique that uses the light of the star, to access the chemistry of a planet's atmosphere. This would be a most effective use for the Hubble Space telescope which is free of earth's atmospheric mess. With the spectrographic technique the Cassini space craft was able to prove that Earth has life. This is the same technique they want to try with extrasolar planets.

    What is needed is a group of open source artists. They don't need to be attached to any given project, but as a team, they would move from project to project to work on artistic stuff on each. Musicians, sound people, and graphical artists would be needed. If such a team could be formed it would be a boon for open source development.

  21. Crack Team on Serious Bug In 2.4.15/2.5.0 · · Score: 1

    What Linus needs to find is a crack team of kernel breakers. People with varieties of hardware. They need to build an automated testing tool that would automatically put the release kernel through thousands of iterations of tests, to ensure that nothing is wrong. What they need is a GNU/Autotest for testing kernels in a peer-to-peer SETI@home style, on non essential machines.
