    Since Photons can convert into electrons and positrons, could those two particles be used directly for electrisity?

    The positron would go into an anti-circuit which would drain it's energy and give it to another electron.

    What's an anti-circuit?

    circuit made of antimatter, since the positron would just anihalate in normal matter.

    This is one for the science fiction writers.

    How is it Sci-Fi?

    I am asking this as a legit question question.

    Can the resulting produced electrons be used directly for electicity?

    Certainly the electrons could, although their usual energy after pair production would be difficult to handle. The positrons could not, because any wires that would actually be available to direct the current to any actual use would annihilate the positrons. There is indeed a current associated with (moving) positrons, but using that current would be totally impracticable.

    Thats why I mentioned an anti-circuit earlier in the thread.

    Hence where the problem solving comes in.

    It will cost you a lot more in energy to maintain the isolation of the "anti-circuit" than you will ever get back from the energy of the current.

    It's science fiction because there isn't any such thing as an anti-circuit. Nobody knows how to build an anti-circuit. Maybe sometime far off in the future, somebody will have an idea of how to do it. That's the kind of topic science fiction writers deal with.

    What do you mean how to we build one. Using tools made of anti-elements which we can already create.

    Antihydrogen - Wikipedia, the free encyclopedia
    http://www.nature.com/nature/journal...ture09610.html

    If we can make antihydrogen we can make other stuff. Obviously as you have mentioned, with time but I don't see how it's science fiction.

    The issue is'nt that we don't know how to make one, it's that we don't have the tech (yet).

    In other words, it is science fiction. How would you hold your "anti-circuit" in place without it annihilating? How would you get the electricity out of it when no physical contact is possible?

    It's a pretty large leap from making a few atoms of antihydrogen to making an "anti-circuit". For one thing, an "anti-circuit" would require anti-atoms much heavier than antihydrogen. If these are to be made from antihydrogen, then that would require controlled fusion... something we haven't really been too successful at even for ordinary hydrogen. Or if these heavier anti-atoms are to be made directly, then I don't think we've demonstrated that this is even possible.
    There are no paradoxes in relativity, just people's misunderstandings of it.

    A magnetic field container and since positrons are often emitted at high velocities during pair production (the higher the photon energy the more likely pair production will occur) you can just manipulate it and force it through a wire made of electric and magnetic fields, if you get what I mean?

    That is how they contain anti-hydrogen. And yea I know a quantum anti-circuit is not as simple as some anti-hydrogen atoms but the principle applies. Not saying we can do it now, only saying it is viable and in a not too far away future.

    So, science fiction then.

    I guess you have a different understanding of the term then. A working quantum computer is science fiction. Cheap and efficient fusion power is science fiction. But both of these are a lot closer (by several centuries, I would guess) than what you are proposing.

    The positron would go into an anti-circuit which would drain it's energy and give it to another electron.
    Do you think that practical energy balance could be positive? Principally if you have positron moving in a vacuum you could retrieve an energy from it with help of MHD generator. Moving charge in magnetic field creates magnetic field. I think you could try to handle positron with help of magnetic fields and direct them. Could you explain your idea in detail? How could be there a positive energy output even in theory?
