-------------Separately
My comment:
(a) The following is about a Alberta, Canada company called Swan Hills
Synfuels.

(b) Coal deposits in Taiwan are small and deep underneath. I have no idea
how this technology can find and reach them. Besides, even if this
technology works, what happens to the empty space after coal is removed?
There may be landslide.
