B Move vehicle in space by rail structure systema

  1. Jan 10, 2017 #1
    Here is my question and please tell what is wrong in this?

    So lets think that we have rail and we move
    Somekind batteries in this rail
    and we have also solar elements to get energy to power
    this rail system and a lamp to throw out enregy from this
    thing that we move. And what we move is batteries.

    And if it is true that loaded batteries weight more than empty ones we do this.

    The thing is at one end of rail and we load the batteries full
    and then we move these to other end.

    So now newtons law say that there will be movement to other direction.

    Now we discharge these batteries and move them by solar energy to other end and
    continue his.

    So now we throw out energy by lamp and we
    can put this thing at moving to some direction at fastening speed.

    But there must be something wrong
    because nowbody seems to use this method to move things at space?

    Or is it too slow or does the batteries not work in this weight in closed scenario?

    So if you have answer to tell me what is wrong here that
    this will not work please give answer
    because this puzzles my mind often.

    Thanks

    The change in mass between a charged and discharged battery is tiny, so this would be a very complicated way to produce almost no thrust.

    Ok! So is there any more better way to do this?

    How about piezo electric way? Can youthink some better way?
    Because if this really works in this first scenario maybe there is
    more efficent way to generate same kind scenario?

    Is there any other way to make mass and "dismiss it
    using electricity or chemistry or some other idea
    than this normal Jet propulsion where only all ready
    stored energy is used to make trust?

    Thakns for your reply! :)

    So by the way could also electric motor or generator work? So when its move to other end it generate electricity but when goes back is of from the pinsion and move easier. But then it makes the other structure spin so it have to move so that generator goes to diverse spin when it load the lamp or something at second turn? So now this rail structure start to move in one direction in space and can get more speed? Or is this science fiction all ready.

    The newtons and trust should work in this scenario becaus the energy is thrown away by this lamp that is powered by generator and the move to other direction has now energy transgfered when the generator moves back to start end?

    So em i right that it is possible to move in space by this way?
    Or is here some physical error?

    In that case, why not just tie down the generator and shine the lamp out the back?

    Well The generator is needed to convert
    movement to elecricity and to lamp.

    So I try to clear this rail structure by the means I can

    Generator is moving in this rail and by pinions or axled
    to this trail so when it moves in this trail the generator
    makes elecriticy and it is in 90 movement
    acording to this trail structure

    And it only make power going to one direction
    but is off when returns. So the Newton law
    to make force in plain movenemnt is less in other
    drection but more in other vecause when loading
    some movement moves to electric generation like
    100W lamp

    But now if these masses are same in this trail structure
    and in this moving generator the trail moves inspace
    more to this other direction because some of this movement
    is changed to electric forces?

    But vecause in space this trail strts to go spinning
    the second time it makes electricity the force have to
    be in difrent direction to stop this spnning
    that can be made using the motor
    in reverce switch or somthing like in gear box?

    But anyway this if i am not wrong makes the thing moveing
    in space and nothing like in jet propulsion have to throw
    away only light energy is thrown owerboard.

    But now you who can math this problem out
    can you tell can this put in real situation in space
    or is it there all ready working?

    I am sorry that i can not tell this in better way
    because I can not draw this to here
    becaus I have this eye condition and i write by
    speec synthetics and so on.

    But if this have something totally wrong
    please info

    Thanks

    Didn't you already use electricity to create the movement? Why convert electricity -> movement -> electricity ?

    Do you mean solar panel motor or lamp one? Is it relevant ? Force change in Newtons is the question. So are forces equal or not if 200d motor move 100w generator in other direcetion and in other the generator is zero wat? So if mass is same in moving parts , does it move in space?

    So, you are trying to defeat conservation of momentum. Maybe we missed it before or maybe we missed noticing before that without "throwing away" the light there is no propulsion, but either way, no, you cannot defeat conservation of momentum. If there is thrust in this device, "throwing away" light (which carries momentum) is what causes it.

    Since this is an attempt at a violation of the laws of physics and we do not allow that here, this thread is locked.

    Maybe it's a language problem, but it sounds to me like a perpetual motion machine or reactionless drive.

    If the only thing existing the system is light, the only momentum available to the rest of the system is what was carried by the light.
