M,

You raise a good point.

We have 2 options.

First is to pedal with every seat having peddles, so if we have 10 million on at any one time and each produces say 100W then we have 100MW of propulsion and as everyone is in aerodynamic (no front so to speak) we should be able to manage a few hundred kmh if we have a tube cover.

Of course gettin people on and off is a bit of a prob but we should be able to come up with some insert and recover mechanisms.

The second is to put the whole thing in a vacuum tube with some sort of centreing guide (perhaps magnetic) and the passengers are in pods with air. Thus we can get the ring up to oribital type speeds.

With this idea and the previous the old emergency cord as used on trains would be a bad idea.

Of course the inherent advantage over jets is that there is no lift to drag ratio so even if motors were used the power consumption should be low.

And if it was not used for transport it could be sold as realestate or as an alternative to round the world cruising with a trip taking a year which equates to about 5kmh, that the passengers can manage to get on and off without special equipment.

Also works well because you can have Mc Donalds every 10km and a sort of drive through (except it would be rotate through, I guess).

Hello All;

 What makes perpetual wheel attempts not work?

We see allot of opinions, and design. They seem like they are in the correct direction, but do not work. There is talk about friction and the keel effect that looks pretty much what has to be overcome in any  falling weight design. Any opinions out there, on what to do to overcome these frictions and keel effects?

Basicly, the weight you use in a gravity motor are suppose to fall from a given hight. But that weight must be lifted upp there before it falls down. And guess what, it takes the same energy to lift a weight up as it release when it falls down. No magic.

The friction isn't an issue, really. Have you energy to spare, there is energy to fight friction - just like in any ordinary motor. However, friction is the very cause why a gravitymotor stops, because there is no enegy to fight it.

Bottom line:
Any given system that are suppose to work with conservative forces, has never, does not, and will never work. Period

So one might say that the question for gravity (or magnet) wheel builders is, "How do I show that gravity (or magnetism) is not a conservative force?"

You did hit the nail right on it. It is like placing a heavy stone upon a table, and show how that conserved position can do work. How crazy is it to believe that? The very same conservation is for gravity in general and magnetism.

Vidar

You can't because they are, and gravity and magnetism have nothing to do with it.

Do you mean that gravity and magnetism isn't conservative, or has nothing to do with the conservation?

Vidar

Is an atom (say monotomic Hydrogen) an example of a perpetual motion device?

The question was; how do you show that gravity and magnetism aren't conservative, and I answered that you can't because they are. And gravity and magnetism have nothing to do with perpetual motion. It is ridiculous and futile to try to attempt to rewrite how forces are to try to explain perpetual motion.

So you believe that man knows all there is to know about gravity and magnetism?  There is nothing left unknown about them that, once learned, could be exploited for our benefit?

I agree that there is nothing within the known (by me at least) reactions and effects of gravity and magnetism that leads one to believe that it can be harnessed to do work.  I also understand that no one can explain exactly what gravity and magnetism are and why they act on other bodies instantaneously and without an apparent medium.  Until that is explained, I cannot say that the answer will not allow for manipulation of the physics behind those phenomenon for our advantage.

I, for one, do not believe the physics we have today is completely flawed.  Only that it shows only what we have learned so far.  And there is much yet to be learned.  Ask any physicist exactly what gravity is.  Unless they are only to recite high school level texts, they will tell you that we just do not know (yet).
