    So anyways, please tell me how you will magically make hydrocarbons with electricty?

    Use electrolysis to crack H2O to make H and O

    Burn H in the presence of C to make CH4, which is a hydrocarbon, and easy to transport.

    When CH4 is oxidized (ie, burnt) you get CO2 which is used at the head of the process where you use electric power to crack CO2 to produce C+O

    And if Australians like me had brains we would be doing this on an industrial scale right now and selling energy to the chilly northern hemisphere. Unfortunately we don't have the required brains...

    That method could be used to test the Pioneer Effect. You would, of course, need to keep the center of mass of the spacecraft near the center of mass of the test mass, not merely keep the test mass from touching the walls of the chamber.

    The system I read about used microwaves to measure the position of the test mass inside the chamber, which obviously impart momentum to the mass, so I imagine you would need to keep the test mass centered as much as possible to have any kind of precision.

    The sad truth is that most people don't want a full-featured computer and are dangerous with it. Give them a web-browser, an office suite, an email client, an IM and a picture manager. Full featured computer will become again the tool for the geek and the developper. The mainstream will go away as it came. It brought us cheap hardware and insecure environment. It was an interesting ride. Farewell and godspeed to you, have fun with your games and movies while I'll have my fun writing algorithms for them.

    I had this argument with my wife recently. She runs an architectural practice and keeps her documentation in a nice directory structure which I keep backed up. I pointed out that there were no CAD files in her project folder. She pointed to the icon for the CAD tool on her desktop and said "its all in there".

    You see, this tool starts up with a nice file picker showing a thumbnail of recent projects. but it hides the location of the actual files.

    The other problem we have is that if I plug her LCD monitor into a different computer she doesn't understand why all the files are different. For her the monitor is the computer and the application is the data.

    What is not a file? A big part of the whole *n.x ideology is that everything is a file.

    Emails are files in the MAILDIR, database records are indeed stored in the DB files. Do you think this is magic here?

    Operators of the machines have to let inspectors validate the checksums on demand, and if it doesn't match then your gaming license gets revoked and the place closes down.

    And how to you suggest to apply that system on an election environment? If the checksum doesn't match, you remove all votes from the voters who used that particular machine? You repeat the elections until no machine was tampered with?

    Yes, sounds about right.

    Or even poker machines. Every machine runs from a PROM. Authorities keep a table of validated PROM image checksums. Operators of the machines have to let inspectors validate the checksums on demand, and if it doesn't match then your gaming license gets revoked and the place closes down.

    Now thats no too hard, is it? Validate a small number of images, then make damn sure they don't get changed. Encourage simple, embedded systems as opposed to big operating systems with 30 million lines of code.

    How do these stable points overcome energy losses caused by drag?

    My guess is that collisions with particles moving roughly in the geosynchronous orbit create drag on anything moving faster or slower than them. If you slide into a valley you will move at a higher relative speed than these particles and experience some drag. This drag will remove the energy you need to climb out of the valley.

    Its just very gentle damping I suppose.

    Well it's a good thing all of us pilots know how to fly planes without RNAV and GPS approaches. Right? You did pay attention in IFR training, right?

    I am sure a lot of them are incapable of flying VFR without GPS now. Look at all those car drivers who end up in rivers because the GPS shows a way across.

  19. Re:Target practice? on Geostationary GPS Satellite Galaxy 15 Out of Control · · Score: 0

    That would be pretty bad, but its still better than scattering a debris field across an entire set of orbital trajectories. At least with this, they can maneuver satellites out of the way until a deorbit strategy can be made. If you blow it up in place, you'll have to wait until the pieces fall out due to the minuscule drag that exists in high orbit.

    In geosynchronous orbit some objects may never decay because hills and valleys in the Earths gravitational field create stable points in the orbit.

  20. Re:Light pressure on Geostationary GPS Satellite Galaxy 15 Out of Control · · Score: 1

    Light doesn't just illuminate something. It has pressure. If you illuminate a satellite from the proper angle with less than the energy required to blow it apart, for long enough, you can change its orbit.

    Light pressure is very inefficient but a laser riding rocket might work, especially if you could exploit thrusters on the surface of the vehicle. Normally laser riding requires the thruster to be lined with an ablative coating which blasts back in the direction of the laser.

    Everything is moving in orbit. If one satellite has a different speed from the others then it is moveing relative to them. In practice rocket motors are used for station keeping. If a motor (or the control system) fails then the satellite will not be able to hold station.
