  1. Re:Debate? on Google-Backed Wind-Powered Car Goes Faster Than the Wind · · Score: 1

    What I meant is that your gears have to be set so that 10 kmh in ground speed produces more than 10 kmh in air that flows out of the propeller. But I'm not sure now, because even that extra 10 would be enough to push you above the wind speed.

  2. Re:Debate? on Google-Backed Wind-Powered Car Goes Faster Than the Wind · · Score: 1

    You couldn't move this thing forward faster than the wind with your transparent propeller.

    I think this could be a better explanation of how this vehicle works:

    If you have an external source of energy, you can have a propeller that creates the airspeed of 30 kmh for example, for a certain rotational speed. Vehicle with this propeller will have the maximum speed of 30 kmh. If there is some wind, lets say 10 kmh, than your maximum speed is 40, but your airspeed is still 30. Of course, you would need an engine for this.

    Second part, if you have a sail, and the wind is 10, your maximum speed is 10 in the direction of the wind. At that point, your airspeed is 0. However, if your speed is only 5, you would still have wind force on your sail, and that force could be made to do some useful work.

    This force is then, what you use to run the propeller from the first part. The propeller is also your sail. Thus, your maximum possible speed becomes 35 kmh. And, there you go, down the wind, faster than the wind.

    It could also be said that the wind does not push your sail/propeller, but the whole air bubble with the local wind of 30 kmh. Basically, a wind warp engine.

  3. Re:Debate? on Google-Backed Wind-Powered Car Goes Faster Than the Wind · · Score: 1

    The important concept is that the wind force is not what moves the boat, but what accelerates the boat.

    That doesn't make sense. If you start from zero, in order to move, you need acceleration. So, whatever causes acceleration, also cases movement.

    If wind causes acceleration, wind causes movement.

  4. Re:Debate? on Google-Backed Wind-Powered Car Goes Faster Than the Wind · · Score: 1

    In the video on the last link, how do we know it really goes faster than the wind? You can not rely on the flags on the thing itself because the presence of the propeller would change the local air flow, would it not?

    And what's the deal with the vehicle on the treadmill? The movement of the treadmill gives energy to the wheels, which turns the propeller. And I guess the electric blower that generates the wind, the speed of that wind is much more than the speed of the vehicle, which is barely going forward. How is this going faster than the wind?

    And us robots take even more clues, and faster.

    When I went back out, since my tires were now cold, when I hit the first turn (a tight 270), the back end kicked out. I drifted the turn, rather than spinning or sliding off the track,

  12. Re:This could be the breakthrough... on 1 Molecule Computes Thousands of Times Faster Than a PC · · Score: 3, Interesting

    I think the real question should be how many measurements per second can you do.

    This is what standard computes do. To get the next step, you have to measure/read the previous state. So you have just zero or one, because that is the easiest to measure. Then you measure in gigahertz.

    How many measurements per second can quantum computers do?

    It's hard to control all those foot soldiers with access to broadcast tech. So they have to educate them how to lie as well. For example, do not use "snipers" when referring to an american soldier, use "sharpshooter". Sniper sounds too bad. Also, do not use the term "the country we are conquering", use the phrase "hostile territory."
