'Elastivity' of graviton collisions

<BLOCKQUOTE id=quote><font size=2 face="Verdana, Arial, Helvetica" id=quote>quote:<hr height=1 noshade id=quote>[Rudolf]: I have a question in terms of the graviton 'wind' blowing 'downward'. Isn't this 'wind' coming from all directions? How will a detector or reactor be able to distinquish the direction of this 'wind' or the lack of it?<hr height=1 noshade id=quote></BLOCKQUOTE id=quote></font id=quote><font face="Verdana, Arial, Helvetica" size=2 id=quote>

Gravitons are coming from all directions. But for any place on Earth's surface, more gravitons arrive from above than from below because Earth blocks some of them from getting through from below. So there is always a net downward graviton flow ("wind") at the Earth's surface, which is why we all feel a downward force. -|Tom|-

Yes obviously (how could I miss that!) I should just go and jump of a cliff and see what gravity does to me <img src=icon_smile_blush.gif border=0 align=middle>
But, would'nt this be comming back to the old idea of a perpectual (hope the spelling is right)/ ever running machine making use of gravity? Otherwise it would require energy to capture energy like a detector that needs electricity.
It would be a tremendous breakthrough if it could be done.

I was sitting thinking afterwards of a practical way such a gravity shielding material could be made use of.
Suppose we can contruct a sphere made of this super dense material it would be (in my humble view) possible that the temperature inside the sphere should be lower than outside because of the lack of gravitasional heating. The temperature difference between inside and outside the sphere could be use in a thermo coupling powersource to generate an electric current. Thus we have 'free' energy.
The biggest problem afterwards would be what do we do with this free energy... <img src=icon_smile.gif border=0 align=middle>.

There may be many simple schemes generating both "free" energy and thrust through use of gravitational shields even without any large body like Earth around.
Take two parallel plane sheets of shielding material, consume the energy from letting them fall upon each-other, then place one perpendicular to the other and move back away to whence it's fallen from wrt the other, restore parallel orientation, repeat the cycle. The scheme generates energy and provides thrust to the centre of inertial masses of the system.
The scheme may even turn out "slightly practical". Take two crystalls with mis-aligned axes, move them together, align the axes, move them apart, repeat the cycle. If both the motion and alignment/mis-alignment are done at mechanical/acoustical resonance modes, then a greater chance of detecting the effect is provided. Enjoy!

Yes. We have a few small engineering problems to solve <img src=icon_smile.gif border=0 align=middle>, but in principle, perpetual motion machines are possible. -|Tom|-

Tom,

It seems to me that "perpetual motion" machines are more realistic by the use of Casimir force. That could employ materials of conrolled conductivity or the use of nano-machines.
In case of controlled conductivity - induce conductivity in parallel sheets of substance, absorb the energy from the Casimir attraction as they move together, destroy conductivity, move them apart, repeat again.
In case of nano-machines - use a "butterfly" with conductive wings, start with wings flat, let fall closer to the conductive plate, fold wings down, pull the "butterfly" up, spread the wings flat, repeat...
Both schemes should provide propulsive thrust as well.

This way we don't insult the academic establishment, btw...
