    The absolute base of a thought, consider a strand of conducting wire suspended through a magnetic field and an airplane flying forward producing an airflow that will cause the conducting wire to oscillate within the magnetic field. The slightest of motion will cause a voltage to be generated and a load connected to the wire will result in a current flow, wire tension and airspeed will determine the voltage (frequency of oscillation).
    The power needed will determine if one needs 10 or a million or more wires.
    (yes I know there will be friction :) )

    A hundred yards of lead might catch some of them. They're slippery little buggers.

    Use the comment section on an FAA proposed rule, that absorbs everything without any effect.

    You could always surround the propulsion ring with an outer ring of black holes. Though, that might drive down property values around the airport.....

    Yes, they do.

    Not trying to give you a hard time, bmcj, but I have seen so many errors in units, and not just here, that I find it hard not to comment for the potential reader who may just be beginning to learn about such things. After all, as a source of energy, there is little difference between a jar of electrons and a jar of hydraulic fluid.

    Probably more energy in a jar of Red Bull.

    Calorific output of redbull is very high, all that sugar etc.


    Which is exactly why its not a healthy food drink.

    Which is why it sells so well. Healthy stuff doesn't sell.

    Bet its full of Caffeine. I can't take caffeine, gets me wired big time. I drank a Cola one time at about midnight and was still up at 3 AM doing exercises trying to wear myself out so I could go to bed and sleep. One reason I don't drink coffee. Milk, water, or orange juice for me.

    Red Bull and Coca-Cola have almost the same sugar content.

    I need caffeine in the morning to prime my brain or it won't fire.

    Major thread drift here:)

    Caffeine tends to put me to sleep. Crazy
