Energy from air

  1. Feb 3, 2006 #1
    Is it possible to make electrons flow in a circuit just using air or electrolysis of air or sumthing like that. Is an aircell possible?????

    What, exactly, would make them flow?

    Not really. Electrolysis of air creates ozone, but ozone is very unstable so it breaks down on whatever it hits. Sometimes that ozone will hit an organic molecule and destroy it. This is why those expensive Ionic Breeze air cleaners are actually worth buying. :wink:

    What about using Oxygen in air, it will react with with many substance and redox may be formed.The reactionrate may be controlled by catalyst

    Well, i am not sure is it possible , just ask and imagine:grumpy:

    In Canada we called that "fire"

    Water can be used as a "cell" and is composed of two of the elements existant in "air" But air is much less dense than water, so I would venture to say that yes, it is theoretically possible to create an air cell, but horribly inefficient.

    One is pretty much stuck with Windmills or Wind Turbines.

    DARPA has been looking into fuel cells that use air for powering micro airial vehicles. In a standard fuel cell a red-ox reaction (although it has been a looooong time since i was in chem) occurs and the electrons from this reaction are used to provide a current and electro motive force. I believe the fuel cell arrangements darpa is looking into use the oxygen in the air as an oxidizer and a fuel such as hydrogen. I am not sure of the technical details or how the configure the circuit.

    redox reactions..... does anyone have a sugestion... is it possible to make electrons flow in any other way??? I know i am acting dumb but is it possible to make electrons jump from one atom to another by some other way?? is it possible to make the atoms unstable???

    when i mean unstable i mean kind of exited state where an electron needs to be kicked out.... not unstable like in the nucleus....

    Electrons can flow by adding an electric/magnetic field. Electrons jumping between atoms is called ionization. Atoms can be made unstable by heating them.

    so is heat the only way to ionize??? i am pretty dumb... is there any other method like some irregularity in the electric or magnetic field???
  14. Jul 20, 2007 #13
    what do you mean by irregularity in electric or magnetic field??
  15. Jul 20, 2007 #14
    The very fact that there are discrete energy levels for specific nuclear combinations means that there is some regular pattern in the electric and magnetic field in-between the electrons and nucleus. Please forgive me if I am wrong, so have any idea to affect this field????
  16. Jul 20, 2007 #15
    as has been already pointed out, these fields can be affected by heating or application of external magnetic fields

    can you tell me how far it is possible to do by using external magneting field??? please give me reading materials, i am just a student.

    heat makes water split into hydrogen and oxygen but this needs massive amounts of heat

    the people who tested the first nuclear bomb thought that they were going to set the sky afire (just a thought)
