He's not joking. He's talking about systems that use electricity to aerate and
a closed non-smell-releasing bioreactor that is nothing like ancient methods. And it
does not need to supply all the fertilizer needs for a family farm to have
a benefit, just partial. Also some animal urine might be collectible feasibly.

The mechanics of all this kind of waste handling by bots is far from developed to the
level of dependability needed to get results yet, but we can still talk about possible pitfalls.

Most people on this list are not going to be really thinking deep in the area of waste -- it's
got no glamour or flash appeal at all...

Can you imagine tweeting about your test results
of a fertilizer bioreactor getting up to ten thousand scrape, shake, bake, UV light cycles
before needing disassembly for repairs? Or publishing the photos to become part of your
product blog showing worn plastic parts with baked on crap and discoloration? You'd only have
ultra-nerd followers for that kind of thing...
