That kindling machine you linked to is being fed larger rounds, not 1" 'slash' material. I'm talking about mountains of slash resulting from cutting down to, say, 2" diameters for firewood and the rest just being left on the hillside to rot away, which seems such a waste of otherwise 'free' kindling. I've already paid to drop it along with the tree, get it to the landing, the tractor and people being there to work and instead of pushing it off the side of the landing, why not turn it into kindling?
The trouble with burning it, and the subsequent conversion into electricity, is there are no connections to the grid where this stuff is and it's not worth carting to anywhere that has such connections, and unless you are relying upon the moisture inherent in the wood itself (which as the slash is the first to lose moisture, there ain't much) it would then need a water supply too, not to mention the relatively low volume of biomass per unit overhead to feed the gasifier/generator.
Are you confusing this thread with the lateral waste wood thread? I can see some connections between them, but the other is more a general dealing with waste wood, and could have large wood and small slash, whereas this thread is specific to creating good amounts of kindling from small slash branches and the like that would otherwise be left to rot. I guess, if there was a feasible way to deal with all waste wood from logging operations, then the slash this thread refers to would also be fed into it, but until such a marvel of alternative thinking surfaces, I'll settle for a super productive kindling machine that can handle otherwise useless slash. I figure it's a little less lateral and as such not as prone to disrespectful derailing as the other thread, if you get my drift.
