Paul and Andrew
I agree with all below, but hazard a guess that small round briquettes
could be ideal. Need no fewer than 6-8 in a stove diameter (guess).
I believe there would be no need for fillers, and could be cheaper or easier
to make than pellets - and maybe briquettes.
Anyone know of a press or other device that makes small spheres?
