here is my original email about this topic long ago. It is the beginning of a definition about what sustainable *is*.

I also agree here, this group wants to live sustainably. Once again I point out that we
don't know how. The prior choice was wrong, and the choice we are making now *may* be
wrong. (In other posts I pointed out how the tribal choice wasn't sustainable either.)

Once again, agreed. But what is the "sustainable" choice? "How" do we accomplish these
things? Quinn pointed at the problem, but he doesn't have a solution. We may not be able
to endure the failure point, the point at which the system crumbles to a not working
state. We don't even know which system will fail first: Antartic Shelf? Tropical Currents
to London? A critical species dropping out of the food chain? Water table in the midwest
drying up (scheduled for 2015 last I checked - 8 states no water)

Political leadership hange will be necessary before any real effective change is
implemented in the US. Bush didn't sign Kyoto because it would cost 'business' money.
Watching LA, SF, Florida, Lousianna, New York and many other areas all sink at the same
time sounds expensive too. (London and Paris too - The Louvre and Mona Lisa will be under
Failures tend to compound and start chain reactions, each reaction compounding with the
previous- gaining momentum instead of loosing it - think avalanche.
To avoid failures we need to figure out "How" to avoid the failures. We know that when
something fails, it wasn't Sustainable. Are we smart enough to figure out if something is
not sustainable before it fails? Apparently not so far. I have checked hundreds of
groups. Nobody knows what "sustainable" really IS. They only know "failure = bad" and
"sustainable = no failure". That tells us nothing!
How do we have sustainable agriculture? The answers are there, but we don't know how good
they are. We know that mulching and not using oil as fertilizer is important, but we
don't know how long we can keep any particular path going.
In the open system that is Earth, we may not ever be able to figure that out. I propose
that we make small communities designed to be sustainable - In A Measurable Way. Those
measurements will allow people outside the communities to choose sustainable living. Or
at least - sustainable agriculture and infrastructure. This is a big project, because we
don't know how sustainable our plumbing is! It has been argued that Rome's success and
downfall was related to plumbing (waste management for larger cities, lead plumbing
leading to insanity among the powerful). Do you want your grandchildren to have plumbing?
They don't necessarily need strawberries from Australia in the winter, but plumbing is
probably important for good health.
So, in the interests of sustainable plumbing, here are a few steps toward a
Sustainability Metric e.g. knowing if something is sustainable.
1. Building materials should be made from renewable resources.
2. The installation and repair should be performed with renewable resources.
3. The infrastructure used to build the materials, installation parts and performance should
all be renewable.
Now that doesn't mean that we can keep on doing it forever, that just means that we
aren't going to run out of the pieces we use to make it in a one time deal. Glue for
example, is not renewable. Most of the plumbing glues are oil based, and no oil means no
plumbing glue. Most insulation, binding and wrapping is from oil based products.
So with the current plumbing, we may just run out of parts or glue some day. PVC pipes
are also made from oil. Most of these parts cannot be recycled, since the polymers break
down and become brittle (they become not plastic).
Steel can be recycled, but it also rusts. This leads us into the next segment. Energy in
and energy out. We can recover iron from rust, and turn it back into steel with a lot of
energy (also requires some rare metals in the process). The amount of energy needed
*vastly* exceeds any sort of reasonable amount. Not to mention the collection of the rust
and removing extra particles, etc. There may be some other chemical to add that rips away
the oxygen from the iron, but is the production of that other chemical renewable and
energy efficient? Usually no. Cheaper yes, renewable, no. Almost all industrial processes
involve entropy. Taking something from a high energy state, and putting it into a low
energy state. We just gather the stuff in the higher state from nature, and then use and
refine it at our leisure.
4. All processes must involve a reproducible amount of energy without undue strain.
5. All processes must be reversible without a reproducible amount of energy.
In my studies regarding solar cells I came up with an interesting fact. One fifth of all
energy produced in the United States is used for the production of Ammonia, NH3. Ammonia
is then used in hundreds of other processes, from making paper to food, in various forms.
(look up the use and production of Nitric Acid for a starting point) The good news is,
the production of Ammonia comes from renewable and plentiful resources. More good news
is, we have the energy production to do this, and can do so cost effectively. The bad
news is, nearly every industrial process we use today would require a similar amount of
energy to do so in a sustainable fashion. I'll look up the number later upon request, but
I think we're looking at 100-500 TWh of power each year. Something big.
6 Each component must be able to be recycled or reused in some fashion.
If we take things out of the loop, then the loop gets smaller unless we pull more in. If
we can't pull more in, we have failure.
7 Every component should be able to be replaced with an alternative.
This is basic "no single point of failure." You could have the most efficient, most
recyclable plumbing system on the planet, but if you can't replace a single part when you
need to, the whole thing is broken.
There are more pieces to having sustainable plumbing. That is a start. I will stop here
for length reasons, and also because number 7 is the first item on this list that
American plumbing actually succeeds with. You can go to the store and buy parts. The
scary question is: for how long?
Is anyone interested in working with me on this topic? Sustainability metrics,
sustainable plumbing, researching sustainable methods, etc.
