[Stoves] Coconut husk - coir - as gasifier fuel ..... was Re: Biochar for the Philippines?

[Paul Anderson]

Stovers,

Art D. did not send his reply to the whole Listserv, so I am repeating 
it below.  His naming of
> mixed coir and shell(And "stuff"). I try to chop dry "stuff "up evenly 
leaves me a bit still unclear about chunks of coir as fuel in 
cookstove-size TLUDs.

Stovers with TLUDs in the tropics with coir available might want to do 
some experiments and send us their results.
