Law of diminishing returns?  I only have a 3.5 kW generator, and I
*don't* have a dryer (clothesline in the basement in the winter,
outside in the summer, works well for me).  Capturing the heat from it
running once a week would be for the most part impractical.  If I had
a large family and ended up doing lots of laundry then a larger water 
cooled generator might be the ticket.  But, as I said above, this
applies to *my* personal system, not one for anybody else, or for the
system I was proposing.  I have considered it though :-).

There is a company out there that makes co-generator funraces that run
on NG or propane.  Heat your house and power it as well!

Quite a few of you have requested further information on the GREEN
REPUBLICANS.  This movement is brand new, there is not yet printed
material to send, other than the posting to which you have
responded, so i will try to answer questions here.

1) The Green Republican Club of Wisconsin was registered as a
not-for- profit, non-stock corporation with the office of the
Secretary of State on March 16, 1992.  The board of directors
consists of Roger Faulkner, Ben Masel, and Keith Klippstein,
Treasurer. We expect to expand this board as interested and
interesting people, and especially candidates for office, present
themselves. Current bylaws call for all decisions to be made by
the board. We anticipate evolving to a more democratic structure
after the November elections.

2) We are not now organized anywhere but Wisconsin, but would love
to hear from likeminded folks from other states, again especially
anyone interested in running for public office in Republican
Primaries.

3) We are not a Third Party. We are a grass roots insurgency
challenging the Republican Party establishment in the September
Primaries. We hope to win over not so much the Party Structure as
the Republican Voter.  Wisconsin is an Open Primary state. Voting
Green in the September Primary does not pre-empt voting for the
2nd, 3d, 4th, or 5th Party Candidate of your choice in November.
The Libertarian and Labor Farm Parties have ballot status, and
there are a handful of Greens running as independents up north.

4) The Ripon society still exists in name, but appears to no
longer be active. It is chaired by Cong. Jim Leach of Iowa. We
spoke to an aide in his office who is interested in our effort,
tho noncommittal.

I find this "Diet for a Small Planet" argument for vegetarianism to
be ecologically unsound. 

Subsistence farmers everywhere know that cattle are walking silos, and
that pigs are machines for converting inedible wastes into edible pig.

Large scale agriculture is dependent on:

	reliable long-term storage of staple foodstuffs-
	good weather-
	efficient markets-
	etc.

In a drought year, farmers slaughter more animals. In a wet year, fewer.

It is both. AIDS makes people more sucseptible to TB, and thus
increases the spread. A person with an intact immune system does not
easily catch TB (although they certainly can catch it).

    I wouldn't put the blame on AIDS victims.  The non-treatable strains
are being breed in homeless/street people and/or addicts.  They get
medicine for treatment and stop taking it when they "feel better." Three
months later they are back for treatment. Since they tend to go to clinics

ECO CENTRAL 7

               The Community Matrix and Stability

We have looked at several different population models in the 
first 6 ECO CENTRALs. In general they have the form

1) dNi(t)/dt = Fi(N1(t),N2(t),...,Nm(t))

for a community of m interacting species. If we set the m 
derivatives dNi(t)/dt = 0, we get m equations for the equilibrium 
populations 

2) 0 = Fi(N1*,N2*,...,Nm*) where 0<=i<=m and Ni* is the  equilibrium 
population for species i.

To determine the stability of the equilibrium, expand each Ni 
around the equilibium value Ni*:

3) Ni(t) = Ni* + xi(t)

where xi(t) is a small perturbation to the population of species 
i. Performing a Taylor expansion of 1) in the perturbations x and 
discarding all terms O(x^2) gives us the linearized equations:

4) dxi(t)/dt = SUM(j=1,m) aij xj(t)   where the SUM is from the 
first index up to the second

or in matrix notation

5) dX(t)/dt = A X(t)

where the elements of A are 

6) aij = partial of Fi wrt Nj evaluated at Ni* for 0<=i<=m

The matrix A is called the *community matrix* and it expresses 
the influence each species has on the population dynamics of 
every other (and on itself, i.e. density dependence).

The solution to 5) is of the form

6) xi(t) = SUM(j=1,m) Cij exp(Lj t) 

where the Lj are the eigenvalues of the matix A, i.e. they are 
the solutions to the equations

7) (A -LI)X(t) = 0,  L = (Lj)

a non-trivial solution to 7) exists iff the determinant is 0:

8) det |A - LI| = 0

which gives an mth order polynomial in Li and determines the m 
eigenvalues of A. These eigenvalues are in general complex 
numbers, the real part of which produces exponential growth or 
decay, and the imaginary part of which produces sinusoidal 
oscillation. Thus perturbations to 2) only die out in time if the 
real part of each eigenvalue is negative. This is the condition 
for the stability of the equilibrium. If any eigenvalue has a 
positive real part, the equilibrium will be unstable, since 
perturbations grow exponentially. If any eigenvalue has a zero 
real part, we have neutral stability, in which perturbations 
persist, as we saw in the simple Lotka-Volterra model given in 
ECO CENTRAL 1.

Putting these remarks together, we can define

9) -lambda = [Real (L)]max

and the condition for stability in the neighborhood of the 
equilibrium (N1*,N2*,...,Nm*) is that lambda > 0.

I believe the book was _Currents of Death_, and I think the author was John 
McPhee.  It dealt mostly with EM radiation from 60 Hz power lines, but also some 
with higher frequencies from cathode ray tubes, like the terminal monitor I'm 
looking at now.  I don't think McPhee is considered a crackpot, but his approach 
on writing this book was mostly anecdotal information from epidemiological (sp?) 
studies.  In order to believe McPhee's conclusions, you need to accept 
statistical evidence which is somewhat sparse and difficult to duplicate 
(unfortunately, that's the nature of this kind of epidemiological approach, but 
it's the only approach available for a study of this nature).  I believe that 
McPhee did mention some animal studies, which are more quantitative, which did 
indicate adverse long-term effects from exposure to high EM fields.

It depends on how shattered technological civilization becomes. If we assume,
as Frank tacitly does, that it is set back no further than to about WWI levels 
of technology, then it wouldn't be very hard to rebuild it. But if you imagine
a world which changes from 10+ billion people to maybe 100- million in 50 years
through famine, warfare, epidemics, and ecosystem collapse, [i.e. my S3 or even
S4] it isn't obvious that the Dark Ages wouldn't look like fat city to the 
survivors. It's unlikely that they would hang onto C manuals for a grand 
restoration. More likely they would think of them as tinder or toilet paper.
And if the world continued to collapse biologically around them for many 
centuries to come, they might just die out.

   They contend that replacement of chlorine with flourine is good and report
that short term toxicity studies gives the FHC's a clean bill of health with
some marginal results indicating _possible_ long term trouble.

I think you've missed a fairly important point here.  "Vegetarianism" (
please note the spelling) is one manner in which we can tread more lightly 
on the earth.  I agree with you that overpopulation is an immense problem, 
but I would submit that overconsumption is also worthy of consideration.  We 
North Americans, constituting a mere 5% of the earth's population consume 
over 40% of its resources, and produce over 50% of the non-organic waste.  
The assumption that the planets resources should be used to serve such a 
small minority of the human populace is as unsupportable as the assumption 
that the lion's share of the resources should go to meet *human* ends (what 
of the millions of other species).  In the midst of all of this, I would 
submit there is a common ground where animal rights activists, 
environmentalists, deep ecologists and human justice activists can meet and 
agree.
