Matter and Energy

[DannyBouy]

So it takes energy

It does. That might be the impenetrable wall.

What do you think?

I think I need to think some more.

[ME]

According to FcDriver that's either a good thing, a necessity, or the thing to redirect... (I'm not sure what he means, but don't necessarily take my word for it).
At least you have some pointers to think about.

The two ideas that come to mind a four spoke device with four weights that slide along the spokes. These have springs to hold them near the middle of the spokes.

However the device is rotated at fixed test speeds.
The mass density will vary.

The other I think is NASA's where a capacitors mass is increased by charging.
So move the capacitor empty - charge - move it back - empty.
Then do this at high speed. This creates inertia thrust.

Perpetual motion does not create energy it uses energy, gravity! In the exact same manner a wind mill uses the wind!

Edit: need to correct it.
Edit: retracted. Previous statement was correct,

I believe that a wheel does not use gravity as a source for PM.
gravity can be utilized e.g. if a wheel uses force it could use gravity to push against , or throw arms up that then use gravity for the descend.
gravity is not the source of the energy.

A blade turns due to wind, we know where the wind comes from

I don't know what to say.

agor95 spoke of NASA working on an inertial drive. Getting into space is part of the puzzle. Dealing with the very harsh environments is another. Most people might not be aware of VIIP. 80% of astronauts suffer from it.

Since nothing was happening in this thread, I thought I'd throw it out there.

Your topic is interesting.

[DannyBouy]

There is one mass at the top of the diagram represented by 2 circles and another at the bottom. The mass at the top attracts to itself. The bottom mass repels.

The attraction might be mechanical, electro-mechanical or magnetic.

[DannyBouy]

Fc = mv^2/r

Since r is constant any change in Fc isn't a factor.

Splitting a mass into two makes a space in a solid. Then the solid can act as a gas, allowing it to compress or expand. No nuclear explosion.

Any thoughts?

Thanks
Daniel

[ME]

"No nuclear explosion", such message either a good indicator or a reason for concern :-)

Since r is constant any change in Fc (centrifugal/centripetal) reflects on the speed (v), or vice-versa.

[DannyBouy]

Thank you ME.

[ME]

What are you trying to do?

[DannyBouy]

I want to make a mechanical model of a gas. Initially I thought I'd have to define it by 4 boundaries or at least triangulate it. Now I think it's sufficient to only use 2 point masses.

I don't know how to mechanically make it work but I think it's possible to use rotation to cause this mechanical mass to compress and expand as it rotates.

It's just an idea of a possible principle.


Thanks

P*V/T = constant
Pressure could be replaced by spring-potential, P*V is Energy [Joule <=> Pa*m3 <=> N*m].
I guess Temperature could be replaced by Kinetic energy (velocity)...

Added:
[..] Which is actually a bit weird now I think about it.
In case of this ideal Gas Law things are expressed as Potential Energy (PE) over Kinetic Energy (KE), PE/KE=constant
While in mechanics the addition is 0: d(PE)=KE
:: It doesn't matter much as PE/KE=1 plus some scrambling with constants. I just never looked at it this way...
[..]

When some mass rotates around a center it requires your previously mentioned Force (Fc) for only keeping it there at a certain radius, it may be provided by a string, or provided by the rim it rests on.
Then you need to find some extra force to bring it towards the center.
As it's mechanical, perhaps you can find a way to get it from across the disc: Levers, scissors, pulleys, another spring.

compression

expansion

Daniel ,

" If it were possible to change a mass by compressing it or expanding it (as the universe is), would energy change? "

Yes it is possible to " change " a mass by compressing it .
If you compress a spring , it has elevated energy , but upon release the energy released by the spring is equal to the energy used to compress the spring .

Compressing it is WORK done , work is energy , energy is mass , so the spring will have a elevated mass while compressed .

The same as changing the velocity of a mass , near light speed , the mass becomes infinite heavy , from all the energy dumped into it .

[sleepy]

Can that be correct? A compressed spring has more mass than a non-compressed spring? Can someone else with any knowledge about this chime in? If this is correct,then a working wheel is only hours away!
