[Digestion] the perpetual motion machine

[Paul Harris]

G'day All,

We do get on to some interesting topics!

Of course there are losses in the integrated biosystem that have to be made
up by rainfall, sunshine and gas transfer, plus whatever nutrients are
exported in produce will eventually have to be made up (no, I'm not trying
to restart a previous thread - please!). It depends where you draw the
boundary and how tight the boundary is. I once gave a paper about Integrated
biosystems and pointed out that Adelaide (where the Conference was) was a
"loose" integrated biosystem as lot's of products crossed the boundary but
Planet Earth is a "tight" integrated biosystem as very little enters or
leaves the biosphere. I can't find that paper just now, but here is an
Integrated Biosystems one if you want some brief information <

Happy digesting,
HOOROO

The grand perpetual motion machine symptoms,
Not really - what you need to see is that there will be losses and
leakages from this "grand system" and to keep it running you need to
reduce your energy losses to minimum and have practically no N losses.  At
some scale your dream will come true.  Then of course comes the cost -->
where you need to decide if it is worth it afterall.
