I don't know. I don't even know if this _is_ an electret. I assume it
must be, or something similar, but the general gist of Brown's (limited)
documentation is that some electric current can be extracted. I have no
idea how or why it works, or even if it does...probably doesn't, but few
seem to have tried it.

I used to make rocket fuel with ammonium nitrate, magnesium dust, and
HTPB binder. Yes, I am somewhat crazy. But I don't do that any more,
even though I never got hurt doing it.
As far as I understand, and much of this is guesswork, the active
ingredient (litharge, ammonium nitrate, tungsten carbide, etcetera) is
not ever melted. Just bound in something else which melts or hardens,
while the field is applied. I guess this isn't really an electret, then,
but some other animal. Like I said, probably it doesn't work, but it
should be easy to test it.

Yeah, the high today was 2F. As far as moving...that's a complicated
story. Many ties of a personal nature keeping me here, plus I sort of
ran away from some things back home. I like the warmth better, but high
temperatures negatively affect me as well.
I drink coffee every few days, I suppose. Not every single day, nor more
than once per day. Is there a benefit?
