...in the form of what may be an accidentally discovered artificial gravity generator, with possible practical applications!:
http://www.esa.int/SPECIALS/GSP/SEM0L6OVGJE_0.html If this effect is real, it's fully 1/10,000 G -- which is not to be sneezed at, and might conceivably lead us to Bigger Things. |

I believe -- although I may be wrong, given my Mr. Wizard level of scientific understanding -- that "angular acceleration" just refers to the acceleration produced by the simple fact that the different parts of the disk keep changing their direction of motion as it turns: i.e., slowing down along one straight-line direction at the same time that they start moving in another. This, after all, is what centrifugal "force" really is: the power of inertia operating because the parts of a spinning object keep changing their velocity of motion along straight-line directions.
I imagine this will turn out to be nothing, just like the Aviation Week "Spaceplane" article -- but who knows? Maybe we'll luck out and it will actually amount to something. One small thing, "Gmbh" means "Limited Liability Company", it's the bit before that is the name of the firm. Oops. Actually, it ain't that small; I've never heard of "ARC Seibersdorf" and have no idea what kind of reputation it has, even given that it's supposedly "Austria's largest research institution". (Tajmar turns out to have been interested in research into gravity control for some time: http://ilfb.tuwien.ac.at/~tajmar/ .) Still, the other guy is General Studies Officer for ESA's Advanced Concepts & Studies Office, which implies some kind of reputation. |
