And just how do you suggest ‘firewood’ be cut and transported? It takes a chain saw to cut - a year or two to dry (green wood doesn’t burn), an ax to split, and trucks to transport... You have NOT thought this one through...
I own 2 axes and a maul myself.
Find a large tooth cross-cut saw—hand operated. Firewood drys mostly from the end of the grain. Twenty inch length needs to season a minimum 12 month, sixteen inch usable in 6 months, and 12 inch sufficiently dry in 2 month. Multiple short lengths in a wood appliance are more problematic to obtain a sustained burn.
