This is about the mc of fresh spruce or poplar in UK, it will burn
poorly in a typical wood stove but an industrial wood burner with some
heat feedback can burn it cleanly. I think there's enough energy in
the dry fuel that suggest it should be possible to burn material up to
80+%mc, though of course ill advised and wasteful. Air drying is
probably the best use of solar energy we can make.
