[Stoves] Stoves Digest, Vol 128, Issue 8

[Tony Blake]

If biochar is so magical why don’t we see truckload sized piles of it in paddocks along side truckload sized piles of superphosphate?
Biochar could cure COVID-19 I’m sure!
I watched the video. Some seem to draw a distinction between charcoal and biochar. Also a cooking time of 35mins isn’t much yet the woman interviewed seemed to list a huge amount of food. Maybe it is each dish to each stove.
And the price? Really?

Tony Blake

Cheap compared to imports from Italy).  Can you confirm - and I wonder the price per tonne at tonne scales - in Bangladesh.  Was this statement in the video to show the monetary importance of biochar from cookstoves?    Any idea what TK value the women might be receiving when selling char from the Akha?.  There was  one interviewee who was a quoted as apparently making big money.
