Gravitic Isotopes?

Okay, I’m poking around on a site which has things that are legitimate, but little used, technology, and I stumble across this paper on gravitic isotopes. Now, T. Townsend Brown did some research into “ion wind” devices which were able to levitate items, but he never was able to make it practical. So, I’m wondering what the heck could possibly be going on with this stuff

My first impression: bullshit. Is “beneficiated” a real adjective? Anyway, the author goes on to say first that gravitational mass and inertial mass have a ratio of unity “for low values of gravity and centrifugal force”, but then he goes on to claim that he can separate “gravitic isotopes” by centrifuging suspended solutions!

I think we’d have heard about it elsewhere if someone had a reproducable experiment that disproved the Postulate of Equivalence.

AFAIK, no known discrepancy between gravitational mass and inertial mass has ever been found. However, there is nothing in the current physical models which say they must be the same. Most physicists and comsologists, however, do assume they are identical and no problems have yet stemmed from that asumption.

While I’ll agree that it is most likely bullshit, just because no one’s poked around with (as far as we know) doesn’t really signify anything. I remember reading about one of the early attempts to prove magnetism and electricity were related, the researchers performed an experiment which should have proved (to their thinking) that the two were related, when the experiment didn’t provide the result they were looking for they concluded that the two were not related, while overlooking the fact that a large iron bar which just happened to be near the experiment rotated to magnetic north at the time the experiment was conducted. It wasn’t until years later that someone else made the connection.
