  1. Re:Uh Typo on Building a Homemade Nuclear Reactor In NYC · · Score: 1

    it's not a tokamak. there is no torus. There are neutrons, which will make something radioactive, eventually, but it'll take a while at the rate a device like this produces neutrons.

  2. ISS won't ever constuct a lunar transfer vechical on NASA Ends Plan To Put Man Back On Moon · · Score: 1

    As Far as I've heard, the orbit of the ISS is not a good one for lunar transfer. ISS is at 51 degrees inclination and the moon varies between ~18-28 degrees. Inclination changes use lots of fuel.

    I'm thinking at best you could send the parts up to the ISS, have them assemble it, and then send it off to slowly change it's orbit unmanned using an electric thruster like an ion engine. It would take a long time, but once it got there you'd fly a crew up to dock with it and go off to the moon

    However, there is no hardware designed for in orbit assembly of ships on the ISS. ideally, you'd want lots of robotic arms that could do the assembly automatically, so that you wouldn't need to risk any astronauts lives with spacewalks. ISS isn't equipt for that, and your be risking the investment in the ISS and the crew's lives unnecessarily by trying to keyhole it into that role.

    An orbital construction facility at an inclination of ~23 degrees WOULD be great for getting to the moon, but not the ISS.

  3. problem is with collecting, not separating on Newly Discovered Bacteria Could Aid Oil Cleanup · · Score: 3, Insightful

    I get WHY Kevin Costner is getting so much press with his oil separation machine; it's not like he has to work hard to get a camera in front of his face. But it's not like the separation process is what is causing an environmental disaster; it's all that oil out in the ocean. If Kevin Costner was selling a machine that can suck up cubic miles of water, that would be newsworthy

  7. Every Device? on MPEG-LA Considering Patent Pool For VP8/WebM · · Score: 2, Informative

    That and the fact that H.264 is already on every device on the planet.

    The only devices I own that will play h.264 are my computers. Only in the past 2 years have devices come out that can play h264. Of those, there are even fewer that you would actually want to watch stuff on. Most of those devices have only come out in the past year

    And if your talking about web connected devices that can play h264, you have an even smaller pool.

    It is defiantly used a lot, but it's impact in the mobile device space is not this huge entrenched market that some think.

  8. The antimissile defense IS flawed on Critics Say US Antimissile Defense Flawed, Dangerous · · Score: 1

    If you are the leader of an up and coming rogue state with nuclear ambitions, you just make lots of missiles. maybe you build 10,000 missiles, with only 5 having nuclear warheads on them. As long as your missiles are reliable, it's a credible threat to the US, as only one has to get through, and MAD rules apply.

    In this example, what good was all the time and money spent on a missile shield? It is, at best, a sieve, not a shield. At worst, it's a welfare program for defense contractors.

  11. Type D ment to work with existing airports on MIT Designs Aircraft That Uses 70% Less Fuel Than Conventional Planes · · Score: 4, Informative

    The type D is specifically designed to work with existing airports without drastically changing the terminals.

    The type H, however, would require changes to current airports. The article says that these designs are planed for a 2035 deployment, though, so plenty of time to make the requisite changes, if the airlines so chose.

  12. Re:Slower than current aircraft on MIT Designs Aircraft That Uses 70% Less Fuel Than Conventional Planes · · Score: 1

    I think people defiantly compare flight time to, say, taking a train or car. But do customers really care that much about flight time? it's not like that's a big selling point when you chose your flight.

    If your flight from new york to LA took an extra half hour and cost 30% less, i don't think anybody would complain

  17. still solar powered, however you extract it. on Possible Breakthrough In Hydrogen Energy · · Score: 1

    Where does all that energy come from? The Sun. all atmospheric processes are driven by the heat energy from the sun. Heat transfer between the poles, which get less sun heat, and the equator, which gets more, creates the jet streams (plus Coriolis effect). So this is just another method to extract solar energy. the question is; Is it the most cost effective and least destructive?

    The law says nothing about food brought from home. It only requires school-provided food meet minimum guidelines. There is nothing in there about giving detention to a student for having junk food.

    You obviously have NO idea how big the marijuana black market is in the US. It's not like having dogs at the airport is stopping the people who want weed from getting it.

  25. Re:Smart move on Texas Tells Cape Wind "You're Not First Yet" · · Score: 1

    Deep hot biosphere theory has been disproved. The theory is that the oil we use isn't millions of years old and made from ancient plants and jellyfish, but actually bubbles up from microbes (or morlocks) that produce it down down down in the depths of the earth. If we just keep drilling deeper and deeper we'll find enough oil to turn our skies a healthy black.

    The origin of the theory came from Thomas Gold, who had a number of wild theories prove to be true, like how the cochlea works, and lots of astronomical stuff. He speculated that since there is methane just floating out there in nebula, then maybe there is methane trapped in the mantle of the earth, below the crust. he speculated that large gas pockets moving and rupturing caused earthquakes. This was before plate tectonics were conclusively proven, so it's an understandable theory in that context.

    However, it's been shown over and over again that below a certain depth, there is no oil.
