By the time all that processing is done, I wonder if it might not be
simplest to just burn the carbon and use the energy (which we will still
need plenty of in any plausible future). There seems little point in
making and burying artificial "coal" when we are still digging it up
elsewhere. My plan was to avoid all that expensive labour and transport
(not to mention land use) by simply having the trees drop the coconuts
directly into the sea. They would have to be dense enough to sink, of
course. But engineering that is probably the least of the problems of my
scheme...
