For example, producing electret batteries and testing them properly (shock, vibration, thermo-vacuum, radiation). Would be neat to have teflon-based electrets (low outgassing - also suitable for space applications), but teflon has a high melting point and apparently its fumes are a health hazard. Could also try plexiglass, grinded plastic (ref). For vacuum, it could perhaps be encapsulated in epoxy.
I wonder if a Van de Graaff generator could be used to maintain the electric field while the dielectric cools and solidifies again.
Found hints of experiments with thermal electret batteries in low voltage high current applications, too:
Interesting stuff. In any case, this is just one example of potential directions to work on.
Remembered reading somewhere that electrets want pulsed high voltage to become properly charged. Van de Graaff would not pulse without a spark gap.
ReplyDeleteDug up a couple of high voltage supplies from old printers and stuff. Now there's the non-trivial task of figuring out all the wiring and interfaces. As I disassembled one of the printers, I noted down all the connections. Dug it up but found it to be Voynich. I mean .. what the hell do these symbols even mean?
