[Stoves] Alternatives to charcoal - transportation & biochar

[crispinpigott at gmail.com]

Dear Paul M

Could you please clarify two things (I can't see the slides. I am in transit). 

Are you basing the transport on a volume basis on the assumption that a vehicle bearing a higher density fuel can carry more?  Someone was talking like that. 

Next, I think you can (very) safely assume that any charcoal stove will deliver 1.5 times as much heat per available MJ into a pot. I aim higher than that but let's stick to average mediocre wood and charcoal stoves. A pretty ordinary charcoal stove will deliver 40% of the energy available to the pot. 

I don't know how that affects the outcome but it is the reality re the processed v.s. unprocessed fuels (char vs wood). 

Thanks
Crispin
