Thanks virtigo - I'm afraid I slept through most of my chemistry and physics classes so I am trying to understand something. I understand that the 1000m autoclave shaft is sufficient to provide the necessary gravity (and energy) to cause the chemical reaction in the coal slurry, therby upgrading it. But if it is the process of de-carboxylation that produces the heat does this mean then that carbon is released in the shaft in order to create these very high temperatures? Or are very high temperatures required in order to initiate the chemical reaction that you say creates the heat (de-carboxylation)? I'm a bit confused about this part of the process. The other related question is how stable is the process at these depths and temperatures? The site for such a tech with its autoclave shaft would have to be geologically stable, wouldn't it?

I have owned MNM and many years ago CAG when it was Cape Range Wireless or some such thing.
