What about ferromagnetic fluid? You can still spin it if you are aiming to push it 'centrifugally' into the features of the vacuum boundary, but you shouldn't lose a lot during the detachment.
For those wondering what this is about before jumping into the PDF. It is an article from the captain's perspective of a flight in 1977, where a Lockheed L-1011's left elevator jammed (corrosion) during take-off forcing the plane to pitch up.
The captain, Capt. Jack McMahan, was awarded the FAA's Distinguished Service Award for successfully landing the plane by using a thrust differential between the wing engines and tail engine to counteract the upward pitch, preventing a stall.
I'm not sure if the US is the same as the UK, but here there are tax incentives [1] to classify, or interpret as much engineering time as possible as R&D.
What is your proposal for an alternative to Facebook, Twitter, etc? Thousands of small independently-owned networks? How would that work when you need to send data from/to arbitrary locations in the entire US/world?

> I consider vision to be a drug -- an addiction. People can get into the horrible habbit of depending on their vision instead of on their brain. IMHO looking at things is a tool of last resort. Once you have exhausted every other avenue of diagnosis, and have given very careful thought to just trying to do the action again, then you may need to open your eyes.
Coding without a debugger is like walking with your eyes closed or driving at night with no headlights. Sure, it may be possible, but you are purposefully limiting your information in order to not become "dependant" on something.
Tooling will always be a compromise of utility vs reliance but there is a reason we don't, for example, build cars by hand any more.
