Next message: Chip Mautz: "Re: lv-ab: Problems ethanol fuels"
one problem with this i see is heat bridges through the supports between
the inner and outer cases of the box needed because the aerogel cannot
support the inner box.
i have long thought of using an open cell foam with inner and outer boxes
connected together airtight then sucking a vacuum on the space with the
foam in it.
some company has made plastic wrapped foam slabs with vaccum inside but i
would not trust these to last. i would want to be able to refresh the
vacuum from time to time as needed.
