    What intrigues me here is the prospect of simulating ALL stones. The
    basic idea is to take biomass (and for Mother Nature, any old biomass
    can be made into stone it seems) and add heat + pressure. All kinds
    of organic and inorganic mixes get piled up on the bottom of lakes,
    oceans etc. Add pressure and heat and you get solid rock. Is that
    kind of cultured stone the future of our land fills? 

    More fancifully, what is the state of the art for "silica aerogel"?
    Can the sand of Fort McMurray be turned into silica aerogel building
    blocks? How well does this "bubbly stone" technology translate into
    uses for BC volcanic and glacial dusts? I don't have BC pumice yet
    but I do have bubbly scoria from nearby mountains. 

Lots more R&D needed.
