Gravitational shielding: The Cavourite problem

<br />How can we reconcile the result of this thought experiment with the Meta Model's deduction that a dense enough material could cause a gravitational shielding effect?<hr height="1" noshade id="quote"></blockquote id="quote"></font id="quote">Almost that exact example was presented in my chapter in the book <i>Pushing Gravity</i> (PG). Gravitational shielding does allow a "perpetual" motion machine to be devised. But because the energy is being extracted from graviton impacts, there is no global failure of energy conservation. This simply appreciates that gravity is a dynamic force, like a flowing waterfall in which every water drop is replaced by another from behind to make the appaerance appear static.

Note that a flowing waterfall can likewise push just one side of a rotor, creating a "perpetual" motion machine of its own. This is the principle of the turbine generator. But because we understand the complete energy cycle, no one claims energy conservation is violated. We simply extract energy from the sources nature provides.

Extracting energy from gravitons (once we learn how) is no different in kind. -|Tom|-

Tom,

So we are talking about an open system from which we receive the energy?

As I mentioned in the paper discussing exploded planet mechanisms, gravitons convey so much energy to matter than the trick is to figure out what keeps masses from exploding, rather than to figure out a way to make them explode.

Of course, in the larger picture, the entire graviton population is merely the "atmosphere" of a "mega-planet", and is therefore very much a closed system. The so-called "meta cycle" described in PG assures that energy, entropy, and graviton numbers are preserved overall. So "open" and "closed" in an infinite universe are relative concepts. -|Tom|-

So could a machine like this be used for faster-than-light propulsion, since the energy that drives it comes from the C-graviton medium rather than from electromagnetic waves?

Longer answer: the vehicle would have to be shielded from elysium because otherwise its nucleons have atmospheres made of elysium that cannot propagate through the external elysium faster than light. (This is why ordinary matter has both particle and wave properties.) But these are "just" engineering difficulties. [] -|Tom|-

One could not, in principle, extract energy from a "uniform" sea of energetic gravitons regardless of what type they were ... for the same reason that one cannot extract energy from a heat sink at uniform temperature.
