I know of some deep shafts in the Sudbury area bored into hard granite --
one 4000 ft. -- "abandoned" -- mined out. I doubt any surface air can ever
find it's way there -- unless "delivered" -- as in fact they had to do so
we miners would not suffocate.

Imagine dropping tons and tons of used care tires down one of those --
having a removable but sealed cap -- driving a single pipe right to the
bottom -- controlled delivery of pure O2 --

Your talking quality synthesis gas!!

Interesting method of recycling??

And one mother of a gasifier!!

Tom -- are there not shafts of that nature in your area??

Or -- as far as that goes -- dump coal down that hole???

And -- true -- other gasses will be evolved -- but your gasifier is so tall
-- long -- that you can re-inject more O2 as required to produce more
synthesis gas -- or -- inject steam of 1800 C -- making that steam from the
extra heat energy produced at the very bottom --

You certainly will not need a feed water pump!!

You also have plenty more room as gasses evolve to the surface to include
some F&T -- and get liquid fuels -- fertilizers -- etc.

Say the shaft size is 16 ft square -- well -- pop a steel tube of say 14 ft
diameter -- or ten feet -- down the center braced to the sides.

And last -- with that kind of delivery tube length -- your probably going
to get very clean gas out the top -- right???
