  1. Re:Thank god! on Mercedes To Phase Out Gasoline By 2015 · · Score: 1

    - Storage and Transport: Whats the volume equivalent in batteries of a full tank of Gasoline (eg: a 300 miles range)? Whats the weight equivalent ?

    This I have no idea about.

    Well, according to wikipedia, the volume of the Chevy Volt battery pack will be a 100L or about 26Gal. Thats for a range of 40miles.
    Thats 1.5 Miles/Gallon, in terms of miles driven per storage capacity needed at the filling stations.

    According to http://www.cleangreencar.co.nz/ the weight/volume ratio of the Prius battery pack is 2.4Kg/Liter.
    (Compare to gasoline: 0.77Kg/Liter)
    According to wikipedia, the Lithium batteries used by the Volt are about half the weight for the same power as the NiMH batteries used in the Prius. But about the same power / volume ratio. So we could says that a modern battery will be about 1.2Kg/Liter (more than water)

    So lets extrapolate, and assume that the Volt battery would be about 120Kg (~260Lbs). How long do you think it would take you to move 120Kg of batteries out of your car, and 120Kg of batteries in your car ? How many "modules" do you tink there would be ? I would say maximum 10Lbs or 1 Gal per module so that anybody can do it themselves. That's 26 modules out and 26 modules back in. Go to the store, and fill up your trunk with 26 gallons of water, then unload them, and see how easy it is.

    I currently spend maybe 10-15 minutes to pump 13 gals every 400 miles. Instead, I would need to "pump" 26 gallons out and 26 gallons in, every 40 miles.

    Another way to highlight the difference (Numbers from wikipedia)
      Gasoline: 10000 Wh/Liter - 12000 Wh/Kg
      Li-Ion : 270 Wh/Liter - 160 Wh/kg

    Some of my math may be off, but it should be close enough.

    Clearly you didnt think it through for more than 2 minutes: Its not just a matter of "just" storing batteries at the gas station.

    Flawed analogies, flawed plan:

    - A propane bottle does not loose capacity, batteries does. I dont want to replace my first batteries with a pair of old batteries that are going to die soon.
    - Storage and Transport: Whats the volume equivalent in batteries of a full tank of Gasoline (eg: a 300 miles range)? Whats the weight equivalent ?
    - Installation/Fill-up: How easy is it going to be to replace the batteries in your car? Are you going to do it yourself ? Are you going to need somebody help ? Will you be able to "pay at the pump" with your credit card ?

    I dont think you can include iron-clad garantees into a proxy vote.

    I mean its just an election, the party (in this case MSFT) tells you his candidates are better than the other's. What they do once they control the board is something else.

    Off course if Microsoft gain control of the board and then screw over those Yahoo shareholder than voted for them, they might be able to sue them, but that takes time and resources. Also I guess the SEC or the government might intervene if it gets really ugly.

    Also even if MSFT controls the board, I believe some things such as a Merger would still call for a vote of all the shareholders, so if the Merger offer was not up to shareholders expectations, they could vote No, even though they voted for having MSFT controlling the board.

  21. Re:The virtual world was the least impressive thin on Matrix-Like VR Coming in the Near Future? · · Score: 1

    Except that the skills learned are PURELY at the brain level: interface your brain with the matrix, which is a big piece of software, then flight a piece of helicopter software.

    Basically, this is a video game, except that instead of having a finger/gamepad interface, the brain interface with the Matrix through the ships computer.
    So instead of grabbing a gamepad and pressing buttons, you jack something in your skull and send brainwaves over.

    Its not because I can control an helicopter with a GamePad that I can they flight an helicopter. You could argue however than it is because the gamepad doesnt simulate the real helicopter interface. That is true, and indeed there are flight simulators used to train real pilots, but even in that case, you cant fly the real thing after some practice with the real thing. You might argue that this is because the simulator is an imperfect representation of the real thing, and I would agree.

    But now the question is, is flying the helicopter in the Matrix a correct representation of the real world?
    The Matrix is designed precisely to be a perfect representation of the real world, so that the brain cannot actually make the distinction between the real world and the Matrix, so if normal people where to learn something in the Matrix simulation, in the same way they would learn in real world, I have no doubt they would remember it when out. This is supported by the fact that Neo still knows how to walk and talk when he is outside. (And I assume here that he learn walk and talk as part of the simulation, interacting with his parents, this is howver an assumption).

    But when the "fly the helicopter" program is downloaded or when loads of guns are "created" one can argue that it is not the same learning process as the real world and not the same control mechanism.

    This is obvious when you think that a lot of the things the people who are "aware" of the matrix do are not possible in the real world. For example some of the kung-fu moves they use are not remotely realistic, the speed they move is impossible. And i'm not even talking about stopping bullets.

    The Matrix is a Software Simulation that a few can control with their brainwaves. I dont see any indication in the movies that the humans actually developed a way to alter their brain to learn new things. They have a way to alter the matrix using their brain, and it is definitely dangerous as some interaction with the matrix could basically "overload" your own brain and kill you.

    If the human had invented a way to jack up their brain, they would certainly use it to gain a physical advantage in the real world.
