Sounds horribly labor intensive and inefficient
How so? Labor wise, you need to get the brush to the chip truck anyways, right? So what's a few more steps to the back of the truck? Doesn't seem horribly intensive to me, but what do I know, I just do exactly that every week. Efficiency wise, well what do you mean? If wood is re-purposed and used to heat homes in the town it grew in or furniture is made and stays local, to me that seems like the peak of efficiency.
The concept of efficiency is highly subjective and varies greatly depending on perspective. If you zoom out a bit and consider the total amount of energy required to- invent, design, manufacture and distribute chippers worldwide, not to mention the cost (resources, not $$$) of operating and maintaining, one might determine that this is in fact a highly inefficient way to deal with a simple problem of brush in the back yard. It is only cultural and industry dogma that leads us to believe this is efficient and somehow better for the world. Who gains? Same as always, Banks, Oil execs, Steel (barons) and insurance monopolies, not the common people by any stretch.
But, it is the way of our culture and society to pass the burden of our convenience to those less fortunate and those who will come after us.
Example: people rave about their iphones are just great and they make life so much more convenient and efficient, wow! Never mind the fact that they are powered by batteries built with Cobalt that is mined by 5 year old destitute children in, where, you guessed it, Africa! Is this really the kind of efficiency we need?
Or how about the bicycle... Is it more efficient to ride your bike across town to go to the store or (because time is saved) is it more efficient to fire up the ol Ford and zip right over there?
None of y'all ever read Walden? Or even the Lorax???
