I recently discovered these aluminum cookpots with stubby rods welded to the bottom to act as fins. These should improve heat transfer to the cookpot.

For those interested in using coconut husk (not shell)
Unprocessed coconut hulls make lousy fuel.
Coconut hull fiber are generally know as coir.

The fibers are processed into mats, carpet backing, potting material, and geotextiles (for erosion control).
On a small scale, the hulls can be soaked in water for at least a month and beaten to break the pith and used as mulch.
The pith leftover from fiber production is known as cocopeat.

It is generally a coarse powder. It can apparently be made into fuel pellets for gasifier stoves. See attachments.
