I've thought quite a few times that some sort of robotic or semi-automated brush clearing system could be an interesting startup. In principle I don't see why you couldn't cut stuff, grab it, throw it in a wood chipper, and haul it out of the forest. The devil is always in the details though and I have no idea what all is involved in operating in the forest or the economics, legality, and politics of it.
