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.

Quoting Paal wendelbo <[email protected]>:
Dear stovers
There is a big difference between countries with
plenty of biomas and not use it for household energy and countries
with scarcity of biomass which use it for cooking. And it is also a
big difference between big commercial agriculture farming and small
scale farming.
As for the Zambia project 200 000 small scale
farmers will produce about 600 ton of biochar every day by using the
TLUD-ND Peko Pe, in addition have their meals cooked and no
transport cost. If they plant some fast growing trees around their
land they will have enough biomass for cooking just by chopping the
sprouting and one ton of biochar a year.
