Move vehicle in space by rail structure systema

Click For Summary

Discussion Overview

The discussion revolves around the concept of moving a vehicle in space using a rail system powered by batteries and solar energy. Participants explore various mechanisms for propulsion, including the use of electric motors, generators, and piezoelectric methods, while questioning the feasibility and implications of their ideas within the framework of physics.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes a rail system that moves batteries, suggesting that discharging the batteries could create movement in the opposite direction, but questions why this method is not commonly used in space.
  • Another participant points out that the mass change between charged and discharged batteries is minimal, implying that this method would produce negligible thrust.
  • Some participants inquire about alternative methods, such as piezoelectric systems, to achieve propulsion without relying on traditional jet propulsion.
  • There is a suggestion that an electric motor or generator could work in this system, generating electricity while moving, but concerns are raised about the implications of energy transfer and the potential for spinning the structure.
  • One participant questions the logic of converting movement to electricity and back to movement, suggesting that it may not be efficient or necessary.
  • Another participant asserts that the discussion may be attempting to violate conservation of momentum, emphasizing that without expelling energy (like light), propulsion cannot occur.
  • Concerns are raised about the possibility of the proposed system resembling a perpetual motion machine or reactionless drive, which are not permissible under the laws of physics.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility of the proposed methods for propulsion, with some questioning the fundamental principles involved, particularly regarding conservation of momentum. The discussion remains unresolved, with no consensus on the validity of the ideas presented.

Contextual Notes

Participants express uncertainty about the implications of their proposals, particularly in relation to the laws of physics, and there are unresolved questions about the efficiency and practicality of the suggested methods.

Here is my question and please tell what is wrong in this?

So let's 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
 
Astronomy news on Phys.org
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 electricity 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

You did not answer the question.

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.
