  2. Re:Also a pony and a flying car for everyone. on White House To Announce IT-Powered Smart Grid · · Score: 1

    The rectification (AC->DC) and inversion (DC->AC) processes required at either end tend to eat up those gains rather quickly, although recent advances in solid state high voltage semiconductors has helped greatly over the old mercury arc rectifiers. If your goal is to be phase-independent, then HVDC rocks; otherwise, AC isn't that bad if you include all the losses.

  4. Re:Innocent? on Thomas Drake Innocent of All Ten Original Charges · · Score: 2

    As everyone else has been saying, a defendant is never "found innocent" - they are found to be "not guilty", which is not the same thing. The prosecutor in OJ's case was unable to convince the jury that he was guilty; the defense did NOT get the jury to declare him innocent. People are found not guilty due to the lack of evidence that they're guilty (they either didn't do it, or got away with it), not found innocent because they couldn't have done it.

    IANAMD, but are there not sometimes clues in the the meaningless jabber? Although not necessarily apropos in this case, knowing that a patient has a cat might lead you to consider toxoplasmosis or other cat-related illnesses that are exceedingly rare. Knowing that she chatted with her friend for an hour might lead you to ask if she was standing the whole time, sitting in her car, etc in cases of leg pain, back pain, etc. Sometimes there is important information to be found in things other than the frank list of symptoms.

    You don't need anti-atoms for weapons. Regular old anti-particles will do; they're much easier to confine, and they're made naturally all the time. See my recent post that points out some of the natural ways antiparticles are produced.

    I think your logic gates are backwards. I used espresso and came up with (Inputs A-D, MSB to LSB and outputs X and Y, MSB to LSB, NOT has highest precedence):

  11. Re:never ever ever on Project Icarus: the Gas Mines of Uranus · · Score: 2

    ...beamed back to Earth via lasers or microwaves?

    I think the vast distances involved would mess that up. The lasers used to do the retroreflector experiment between Earth and the moon had a calculated divergence of about 1.04 x 10^-3 radians. Using a 1m laser at Uranus, the divergence would have to be 2.8 x 10^-4 radians just to make the beam the same diameter as the Earth. That's a factor of 4 or so. To get the beam into a circle that covers the same area as the state of Texas you'd need divergence on the order of 2 x 10^-5 radians. Suddenly you're looking at a factor of 50, and that doesn't take atmospheric effects into account. Add to that the complexities of precisely aiming such a laser, and I think you'd be hard-pressed to harvest must energy.

  13. Re:20 MW-What? on Using Flywheels to Meet Peak Power Grid Demands · · Score: 1

    Article says each flywheel can provide 1 MW for up to 15 minutes. As I asked earlier, why do they need 200 of them if they're 0.25 MW*h each? Maybe they meant 20 MW*24min.

  14. Re:Cool, energy arbitrage on Using Flywheels to Meet Peak Power Grid Demands · · Score: 1

    I _love_ hit-and-miss engines! Not only do they not fire if turning over a certain RPM, the exhaust valve is held open so that there are no compression forces - only crankshaft and piston drag. Those engines are designed to run weeks on a tank of gas (and cooling water - they usually use evaporative cooling, so you have to fill them up with water).

    In this video you can hear the exhaust pipe 'gasping' as it freewheels and the engine firing with a 'pop'. The red tank toward the tongue of the trailer is the coolant tank. Note that the flywheels are turning - they look strange due to the video framerate.

  15. Re::-) but a serious question, what % loss? on Using Flywheels to Meet Peak Power Grid Demands · · Score: 1

    The article says that each flywheel can "...absorb energy from the grid and discharge 1 megawatt for as much as 15 minutes." Therefore each flywheel is good for up to 0.25 MW*h, and 200 of them should be good for 50 MW*h, not 20 MW*h. I guess there are inefficiencies depending on how fast you extract power, much like batteries.

    actually, you should have a right to do anything so long as it doesn't trample those same rights afforded to your fellow citizens. eg: you have a right to go off trail while hiking...

    I must disagree with that statement. Going 'off trail' damages the very landscape that you and your fellow hikers are there to enjoy! I couch statements like yours in logic like this: "What would happen if everyone did it?" If the outcome for everyone is bad, then it either can't be allowed at all, or there must be strict regulations. Examples:

    1) Walking around on the sand at a beach - ok for all. All those footprints will not matter in sand.
    2) Hunting - not ok for all. Must be regulations on number killed, etc.
