[Stoves] Re looking for a stove design for large amounts of biochar

[Paul S. Anderson]

Dear Paal and stovers,

Paal is absolutely correct.  Each household produces about 1/3 kg of  
biochar each day.  If the biochar yield by weight of the raw fuel is  
20%, the biomass needed is 1.66 kg per day.  If 25%, then the biomass  
is only 1.33 kg/day.

Less than 2 kg/day represents fuel savings compared with the  
inefficient 3-stone and other fires.  AND they are getting the  
biochar.  This correctly contradicts the people who say that making  
biochar leads to increased cutting of the forests.  Reasons:

1.  The Peko Pe and most other TLUDs keep the fire focused onto the  
cooking task.

2.  These micro-gasifier stoves can use many types of biomass, so any  
energy-equivalents of cut trees that can be replaced with maize cobs  
or ag-waste briquettes also means LESS deforestation.

The Wendelbo project in Zambia with 200,000 rural households is a  
major effort that should help the world realize that the TLUD  
micro-gasification is a truly significant part of the solution we all  
are seeking.

I did NOT say that TLUDs are THE solution.  But it is major.  This  
needs to be recognized and implemented in so many more locations.   
Stovers, the TLUDs are not a bandwagon.  They are a tidal wave of  
benefits.  I hope more will become involved.
