Gravitational Engineering - What We Can Do Now

My feeling is that the gravity effect is so small compare to all the noise .

Jacques, you're risking having the fate with someone else who raised the very same issue. He was attacked in concert and finally expelled from this board. I suggest you ask forgivness for talking about noise issues and be a nice kid. This is a game board here nothing serious pal. Only those who make serious and real experiments deal with the noise issues. LoL

Stick to science and do not insult the participants. No flame bait is welcome here. You can respectfully disagree about ideas without attacking people. -|Tom|-

If we manage to get 1 cm thick, 100 g heavy "monsters" for the SOG setup, then it's reasonable to expect a force signal of 10^-14 to 10^-15 N in the receiver xtal.
It may turn out easier to actually gauge the effect with the cheap "proof of concept" setup, by dividing the reading of periodic signal in the receiver by the Q-factor of the receiver xtal and scaling the result to the real SOG setup (using the size and mass estimates).

Hi
I am been reading this thread and I have a question:
I seen some equation but does any body tried to put number in it ?
Evaluate the masses, the masses displacement, the electrical leak.

My feeling is that the gravity effect is so small compare to all the noise .
Thank you

The problem of the smallness of the gravitational effect is large enough (pun intended) that it's not necessary to put numbers on it yet. You are welcome to tackle that part of the problem now if you like, however. We can use all the help we can get.

AB has suggested that it is possible to detect a single gravitational impulse lasting for about 1 nanoSec. He makes some good arguements in favor of this thesis but I am still skeptical and doing some off-line research to see if I can determine which of us is "right".

I am not afraid of being expulsed from this message board because I think that people here will respect you as long as you respect them and because I think people here are intelligent enought to admit they can make error.
Thank you AB for your answer. Is this an evalution of the gravity force of the whole cristal at distance of 1 meter or the variation of the force caused by the oscillation ? Also using a big cristal would not reduce the frequency ? An other thing, if you take in account the lower limit of the SOG given by Tom Flander (2 * 10^10 c) you will have very small time delay...

I would like to tackle this noise issue but I am not an engineer or a mathematician. I am more an amateur and observer...

The frequency response may get limited only by the transmitter inertiality, that's where we may need some further tinkering. We might need to excite the transmitter inductively in order to directly generate the proper phase of E inside the material of transmitter - but that's only in the case of too slow reaction to simple voltage excitation.

And don't expect the exact figure for the SOG measured is such setup, rather a lower limit for that, hopefully superluminal <img src=icon_smile_wink.gif border=0 align=middle>
