Since I’m already thinking about some new tinkering projects for the post
RepRap era I stumbled upon the following nice experiment.
Since the linearization of Einstein’s space-time-metrics depends on the assumption that the distortions are quite small,
there went up criticism from certain members from the CCC, like Raoul, that such equations could never be used in order
to describe something as a rotating niobium ring (Like in this experiment).
The measurements taken seem to support Raoul’s argumentation.
Being a factor 20 off the calculations shows us wonderfully that assuming a non-linear system to be linear
only works when the numbers you’re crunching aren’t that big, otherwise you miss some values…
But remarkably: The measured values were 20 times bigger then predicted, which means,
that you can actually get more power out of the system then you’d expected.
Which means, these measurements mean: The idea of antigravity isn’t as brain damaged as some may think…
Only: the problem is now the same as it is with the electric rockets…
What’s moving an electron within an B-field, it’s the Lorentz force, but this one is damn weak.
And also the Lorentz force doesn’t actually move an electron into an opposite direction,
it usually just pushes it a little in it’s already existing trajectory…
Same for the gravito magnetic Lorentz force.
Seems as the laws of physics will still stay a bitch for a while.
But the experiment is still a cool idea, or as General Hammond would say: “Spinning is so much cooler than not spinning”
