I know that gas producers that have nitrogen in the fuel can make
ammonia. This was a co-product back in the day of town gas. Some people
that run their personal gasifiers claim that the condensate smells like
ammonia but I have no details.

Thank you very much for that information!!!!!!

I have made charcoal Fireballs for fuel (agglomerations):
<http://www.puffergas.com/fireballs/charcoal-fireballs.html>

Charcoal can be very dusty to work with so I am thinking about making
smaller sized agglomerations (Fireballs) that are enriched with urine
(animal/people vinegar). After applying the agglomerations to the field
they would dissolve because I would choose starch as the binder.

I think this would also be a good way to sell Terra Preta to the public.
They would not even know that they are using Terra Preta. Of course it
would be a small amount per acre but it would be a start.

Good idea or bad idea???


Best regards,

Jeff
