  1. Re:Free energy on DIY Solar Resources? · · Score: 1

    Hang on. I just checked out the price, $2500. This looks like an emerging , unsaturated market.

    Heck, you can even get a 12/24 volt DC air conditioner http://www.dcbreeze.com/ There's plenty of low voltage DC appliances.

  3. Re:Must it? on How Water Forms in Interstellar Space at 10K · · Score: 1

    The components of a collapsing cloud have a lot of gravitational energy to bleed off before they can coalesce. The natural result is that they heat up, volatilizing any water ice and driving it away. Even after the Earth formed it is generally believed that early bombardment left oceans of magma on the surface, another environment not conducive for accreting water. This leads to speculation that water came to Earth after the surface solidified, possibly by comets from the original pre-solar dustcloud.

  4. Re:Not quite the same thing really on Finnish Electric Solar Sail Nears Implementation · · Score: 0

    Mod Parent Down. Solar Sails get their momentum from the photons in sunlight, not from solar wind particles.

    The diameter doesn't matter nearly so much as the cross section.

  6. Re:I don't believe it on Scientists Create Room Temperature Superconductor · · Score: 1

    Or maybe I do believe it. It's fairly hard to get synchrotron time if you're a crackpot. The article is sparse on details though, especially the pressure used...

    Really.. I'm not just saying that.

  8. Yeah on Online Parent-Child Gap Widens · · Score: 2, Funny

    ... and children never lie on surveys.

  9. Re:Self-rejection? on Teen Takes On Donor's Immune System · · Score: 3, Interesting

    What everyone seems to be missing and what is so cool about this case is that it was [b]stem cells[/b] that migrated to the bone marrow. These stem cells were in an untrained state. Once they differentiated into B cells, T cells, macrophages, etc., they went through the same training process that happened to you as an infant, where any self-reactive cells are programmed to self destruct. It really was a full reboot.

    You don't know how tall he is. Maybe he likes short ladies.

  12. Re:I don't think it means what you think it means. on Huge Hydrogen Cloud Will Hit Milky Way · · Score: 2, Interesting

    Maybe people who don't understand what will happen will have a problem. Like the kind of people that think they will simply pass through each other. What really happens is that colliding clouds form a shock front and can heat up to millions of degrees C.

  13. Re:Ask slashdot on Largest Black Hole Measured · · Score: 1

    Some weirdos think our universe is the inside of a black hole, so no, there's no limit.

  14. Re:How about a study with n1? on Alzheimer's Treatment Mooted · · Score: 1

    The AC who wrote the parent to your post obviously knew that. He/she was saying that it doesn't cross the BBB when used on-label, not off-label.

  15. Re:Awesome! on Upgraded Hubble To Be 90 Times As Powerful · · Score: 1

    I was sort of disappointed when my doctor took some x-rays and then had to convert them to a visible light image to see them. I thought he could just magically see x-rays. And by the way, "ascetic appeal" is a very funny term, almost an oxymoron. I think you were trying for a different word.

  16. Re:In Soviet Russia on Scientists Fly to 2008's Most Dazzling Meteor Shower · · Score: 1

    Of course when I wrote "meteorites" I meant meteors.

  17. Re:SETI Scientists? on Scientists Fly to 2008's Most Dazzling Meteor Shower · · Score: 2, Informative

    The meteor acts like a old-fashioned flame test, revealing the identity of the elements present in the meteoroid by the spectrum of the emitted light. They're checking for the presence of organic matter, which has something to do with the search for life, if not specifically intelligent life.

  18. Re:In Soviet Russia on Scientists Fly to 2008's Most Dazzling Meteor Shower · · Score: 1

    Even in an area with low light pollution, the atmosphere is still scattering or optically distorting light from the stars, meteorites, etc..For a favorable view of anything in the upper atmosphere or beyond, it is imperative to get above as much of it as possible. For a good idea of what's wrong with looking at something through a lot of atmosphere, go somewhere with low levels of light pollution and watch the stars twinkle. It's not the stars jumping around, it's the turbulence in the atmosphere that causes that.

    Yeah, maybe if you had actually tried fact checking you'd have found that the X-15 was rocket-powered, so no jet engine.
  23. I see an application here on Picture-Sorting Dogs Show Human-Like Thought · · Score: 1

    Maybe we can get dogs to scan the surveillance images from the 2008 Olympics. Surely it would be cheaper than IBM's Smart Surveillance System. Heck, I know a dog that will work 20 minutes just to lick the crumbs off someone's face.

    I've been there. It's already being mined for salt. Not only do they leave holes but they leave the salt in conical piles to dry out (the water table is quite close and actually pools on the surface in some locations).
