It is a highly functional gasifier that makes two good products -- gas
and biochar - in variable proportions. As you know it is a challenge
just to sell a gasifier in energy markets that are dominated by low
cost natural gas.
The problem in Haiti is not the need for biochar, but the lack of clean
fuel. The fuel to be used may be contaminated to the point that the
biochar will be useless, it will make the ground unsuitable for growing
food. However, the gasses will be suitable for heating, which does not
need really clean gasses.
Contaminated biochar may have detrimental effects wherever it is used.
Ash, however, will not change the soil where it does not reside.
