[Terrapreta] water gas?

[Jeff Davis]

Gerrit,

Steam plus very hot charcoal = water gas (H2 + CO)

Nice gas indeed!

I think the old time forge people controled the charcoal fire with some
water plus air.

I can not say if what you want to do is dangerous or not. Too many variables.


Kindest regards,


Jeff
