Mark,
I am on a similar quest to yourself, although my Pigs
will be
supplying the waste for my Methane Production( that
parts easy ).
The power produced would cover my Fish water pumping
requirements/
and/or battery charging requirements.
Even though I work in the Gas industry, I have no
access to the materials
and
equipment ( or vast sums of Money ! ) that Oil
companys work with.
But I know how they do it.
If I find anything thats going to fit my needs, I will
certainly share it.
>From my point of view it has to be :-
a.) Affordable
b.) Very Reliable
c.) Relatively labour free.
d.) SAFE
I have a few ideas, and they do involve storage of the
gas, but at only 20
psi.
However I am still in the "try it and see" stage.
If anything works I will be sure and share it.
Steve H
SNIP
Steve, Brent.
I appreciate the technical feedback. I have been away
They have examples of successful operations here in
the US. Lots of info
there. Ok
.out with the propane tanks
I'll keep
reading
lol.
Is storing it practical at all on a smaller scale? If
we could
get the states to pass favorable net metering laws, it
could be
used to run a generator. Minnesota is the only state I
know of
that requires energy producers to pay farmers retail
for the extra
electricity produced. This would go a long way to
making systems
pay for themselves.

Just one more word of caution. Don't assume that all
DC electricity is safe just because it is DC. We
sometimes use 110v DC control circuits on presses
because the on/off cycling is faster using direct
current than using alternating current (after all ac
reverses 60 times per second in the US).
Also it may be just my imagination, but 110v DC hurt
me a great deal more than 110v AC ever did.

This is from a note sent to me by Raul Martins.----
I think that time is up for you to understand that
biogas is
not so important in anaerobic biodigestion as people
claim.
We can get, in anaerobic biodigestion, only about 2 or
4% of
biogas measured over the weight of the manure "in
natura" fed
to the biodigester. >From this biogas, we have
Methane - 60,0%
Carbonic Gas - 38,0%
Sulphide Gas and other gases - 1,5% to 2,0%
So, the usefull part of biogas is very small with
relation to
the weight of manure or organic matter fed to the
digester, and
we need a very large size digester to produce large
amounts of gas
economically usefull.
----
So, from and aquaponics view bio-digestion to produce
energy may
not be practical with the volume needed, the need to
clean the gas,
store it, etc
It can still be used to process the
waste into a
valuable fertilizer and destroy pathogens though, so
it may have a
place. Steve, from looking at the AgStar site though,
it
most definitely holds potential for your hog
operation. Good Luck.
Part of what I love about this list is being able to
throw an idea
out
.any idea
.and see what bounces back. The
wealth of knowledge
here is incredible.
best wishes,
Mark

LOL, I used to have a greenhouse and it used to make
me cringe when I
saw members of the "pinch and clip" crowd come in.
(These folks come
in both the male and female variety). But I finally
figured out that
they weren't going to buy that plant anyway - it was
against their
principles!
I finally stopped worrying about. The amount of
energy I had to spend
worrying about it didn't justify the small amount of
loss, and they
often went home and called 10 of their friends about
the neat plants I
had - and some of those folks did come and buy.
Once I approached an _suspected_ elderly clipster, and
said, "How
about if we work out a trade of some of your labor for
some free
plants?" This fellow turned in to a great friend, and
worked
tirelessly in the green house for no pay! He was
retired, lonely, and
just wanted to hang out with us and grow plants. I
gave him a room
for about 10 flats for whatever he wanted, and he came
and went as he
pleased. Everyone should be so lucky.

Hi Carolyn,
I really do not think that you have to worry at all. I
have never heard
of anyone being hurt by 12 V DC. You can grab the
poles of a car battery
with your bare hands and nothing will happen. Connect
it the way the
supplier tells you to.
Have a nice weekend

Hi group,
I have watched this thread with a lot of interest.
I even created a little *safety notes* file from it.
Arlos may have to rest his fingers for a few
days
.lol.
thanks to all who contributed.
You would be amazed at the ways people can find to
hurt
themselves. I know of a guy that killed himself with
his
Ohm meter (just a nine volt battery!) trying to
measure
resistance in the body. He hooked the meter up to each
wrist.
I think he used like accupunture needles in each
wrist.they pierced the skin
.HUGE mistake. The water in our
bodies
is saltwater
.highly conductive. The resistance our
skin
provides us protects us. The circuit path crossed his
heart
and killed him
bad experiment.
have a great weekend everyone,
mark

Biogas systems can be cheep and simple.
You can line a big lagoon with HDPE then float the
same material over it to
catch and store the gas. If you put a sand trap at the
front end you can go
years with out maintenance in the pit. Location has
some control on the
exact design. If your pigs are in confinement you will
need heating and or
cooling.
This is where the biosystem concept will save you lots
of $$$$$. There is
enough CO2 in the air of the pig buildings to increase
plant growth several
% if routed through greenhouses. The effluent from the
Biogas is very good
"organic"
liquid plant food. Cuttings and waste from the
greenhouses feed the fish and
the gas digester.
The cycle produces gas that can be used for direct
heat but better make
electricity and use the waste heat to provide
air-conditioning and
heat for the small pigs. The "total system " approach
uses all waste even
the smell from the pigs. There is much more but I
think you get the concept.

Chris,
Harborfrieght carries a small 1/2 hp 6 gpm (chinese
made) that is about
the best value I've seen for a small, continuos duty
pump (one note on this
particular pump, if the pH goes acid, the interior of
the pump housing is
eaten away quickly). Grainger on the other hand does
not sell to the general
public unless you have an account with them and their
pump pricing is are a
little steep. Sears has entered the market with a line
that is about half
the cost ( & easiest to rebuild on the market) of
Stay Rite pumps. Reading
and understanding a plate on a motor is difficult at
best for the
layman.Depending on the application , efficiency and
pump curve, there are
hundreds to choose from on the market. I particularly
like the dual voltage
feature when customers due not have 220 available and
line loss limits are
not a factor. The greatest improvement in the past ten
years has been the
improvements to VFD'S (variable frequency drivers) not
only in cost but in
size and PLC (programmable logic control) interface.
This is a huge
advancement over stepper motors where constant start /
stop became a
maintenance nightmare. E series pumps used by
Franklin, GE, Gould , Grunfos,
Osmonics and Tonkin reduced utility bills
dramatically. The American Water
works Association publishes the best pump handbook
I've ever seen and would
be well worth the money for anyone running an
operation using pumps. When I
spec a system it usually includes the design of a
duplex system of dual
pumps. Some alternate such as lift stations, some
parallel, some series and
some as redundant backup. In the case of clean room
applications where down
time can mean millions lost in hourly production, a
second pump system is an
easy sell. In light of the fish stock insurance post
yesterday a back up
system and system monitor is not a bad idea and would
probably qualify for
lower insurance rates, if a system loss ment thousands
of dollars in lost
productivity. The use of solenoid valve's with either
hydraulic, pneumatic
or electrical actuators would make for some very
efficient systems.
I could go on all day about this
Arlos

I have one of those little clear water pumps but they
only put out 380 gals and hour, with a half horse. The
1/4 horse grainger pump is puting out about 2400 gals
an hour in my system. If you need a pump like that go
to a local branch of grainger they will sell it to you
and even deal a little on price.
I really like the new AC controlers but they are

I have 2 whiskey barrels that I'm hoping to set up
with a small aquaponic system to grow a few lettuce
plants. I'm thinking I could use guttering of some
kind or even a hydro channel of 4 inch pvc like we've
built for our hydroponics? How much (feet?) can 2
barrels of goldfish do? I try this first to see if I
can show hubby that this could be something we could
do to grow stuff. Diversification is what we are
about these days since a small farmer can barely
survive (depends on if you want to eat or not) growing
apples. We've taken some of our apples direct through
farmers market and are doing the same with our
greenhouse and garden produce. We found lettuce (GOOD
lettuce) is something lacking at the markets and being
able to take aqua/hydroponic grown lettuce,roots still
intact, makes for happy customers to get lettuce that
"looks" like it's still growing =:> and not picked
hours or days before being sold.

the light. I have
also seen somewhere a floating cover, for a pool
markyou that was dubbed
a solar cover, used for heating. I have seen a kid
fall on one and was
still able to move and roll on it without falling into
the water. Last
week on the news here, sadly it was shown that a baby
drowned in a
bucketwith 6 inches of water, in a 14 inch diameter
pail
. she was left
unattended in a yard. So this is real folks
.!!
There are many ways to give fish a "photoperiod"
without having natural
light. One could have covered tanks, inground, with
the growbeds right
over it for space saving.
For more on this inground thing, try writing Ted
Ground offlist. (No
puns intended. His tanks were inground.)

Brent,

This is the way I am headed, although I live in the
tropics and Don 'at' t
need the heat. Can 'at' t set up an evap cooler as its to

One additional step I have planned is a final "Lagoon"
after the Bio-digestion phase, where I grow Duckweed
to feed the Tilapia
a high protein food source supplement.Any Remaining
Liquid from the
Biodigestion phase goes to the fruit trees.
Any dead fish get boiled up and fed to the Pigs. They
love them !

Bert
I'm not selling W.W. Grainger pumps but I haven't had
any trouble with them either.
Because my pumps run continuously I have to have at
least 15 lbs pressure to open the sprinkler type
valves in my distribution lines.
So I'm Using a W.W. Grainger 1/4 HP booster pump Model
2PC24. At first I used 1/3 HP 2PC25 but it made too
much water. It ran 24-7 for six months with no trouble
except for rocks in the impeller. A better screen took
care of the rocks.
In the beginning I used some cheap sump pumps,from
Northern tool, for my return pumps, but It took two of
them to move enough water and one only lasted two
weeks.
Next I used a wayne 1/6 hp sumppump, in the winter it
was fine but when it got warmer I needed more water in
my grow beds and went to a 1/4 HP. Then in july I
upped To a 1/3 HP This returns all the water to the
fish that the W.W. Grainger 1/4 removes. If it gets
hotter in Aug. and I still need more water in my grow
beds I'll be back to the 1/3 W.W. Grainger pump and 2
sump pumps.
Chris Jeppesen
If You have had trouble with a specific model of pump
Please share that openly and we will all profit from
your experience.

Steve H,
I've heard the same thing mentioned here on the list
about it being to
humid for a swamp cooler. Please expand on this. I was
in Viet Nam for
wonderful vacation in 1970 and we used swamp coolers.
If the humidity is
90+% outside the greenhouse, how can a little more
moisture hurt. Man , I
remember living in 3 feet of water for 2 months
straight during monsoon
season. It was so hot and humid that 5 minutes after
the rain stopped the
steam would start going back up to the sky.

We use the waste heat to cool. 185 F and up will
produce 46 F cool .The heat
from a generator fueled by Biogas will produce 14 tons
of cooling per
180,000 BTU's. In hot climates the cooling is the Key
part. We cool our
breeding fish under the greenhouse walkways and fool
them into spawning
more times per year. The cooling also allows us to
process and ship at lower
costs.

Kris,
I dont know what the climate is in Vietnam. A lot of
the climates are
often "loosely" called tropical. Big difference
though, between sub-tropical
and Tropical. There are Seven different Sub-climate
classification regions
across the Philipines alone.
I have seen Humidity readings of 97%. It depends a
lot on your
location, wind movement etc. I live in an area thats
completely landlocked.
There are 9,000 feet mountains on 3 sides. Almost No
wind movement at all.
So the Humidity levels just climb as soon as the Sun
comes up.
Only time I see any steam is first thing in the
morning, around
6.30, the steam starts coming off the surrounding
hills. By 7.30, its
already
so hot that its gone. The sweat just does not
evaporate from your body.
Even now, during Rainy Season, I never see any steam.
Everything is just
very wet.
Water temps stay between 26C to 31C, all year
round.Night and day.
Perfect Tilapia temps !
At certain times of the day, and in a location that
has a bit more wind
movement, a swamp cooler might work a little bit, for
a while I guess.
Doubt if its very energy efficient though. I also
doubt if the comfort
factor would be any better than using a small electric
fan.
Personally I feel more un-comfortable in cold
Humid-air, than I do in hot
humid air.
My Pigs Just need shade. They get hosed down 2 times a
day when they
are cleaned. I Don 'at' t know a lot about Pig
Breeds
Maybe they are a different
breed
better suited to the Tropics.
I have seen a few ideas mentioned on the list though,
such as keeping the
Greenhouses
cool, that I will try at some stage. Just to see if I
can drop the temps a
Degree.

Steve H,
I am still not sure about what you said,
" Can 'at' t set up an evap cooler as its to humid "
I'll rephrase. I don't understand how 97% humidity
outdoors, when sucked
through an evaporative cooler is more harmful than the
excessive amount
of heat it removes. I've been in greenhouses near
Phoenix that stay about
80 degrees F when it's a 120 outside. I mean isn't
100% per cent humidity
as high as humidity can go and is that harmful to
plants?

I took a similar vacation about the same time and
don't remember any swamp coolers. But there where a
lot of refrigerated window units. A
swamp cooler is big compared to refrigerated unit and
is full of water on the bottom that is pumped on pads
that line the wall area. Air moves tru the pads and is
cooled by the evaporating water. They only work in low
humidity desert areas. (Nevada Arizona Utah WYoming
etc.) could you be mistaken about swampcoolers in Viet
Nam?

Here are some organic, organic hydroponic, aquaponic,

These are mostly Web-based addresses (to save my

I hope this leads you in some good directions. Good

In Phoenix the outside humidity is only 20 to 30 %
So an evaporative cooler can add another 60 to 70 %.
In doing so it cools the air because it is the heat
in the air that evaporates the water.
If the outside humidity is 90% and evalopative cooler
(swamp cooler) can only add andother 6-7% so the
process
Is at best 10% as efficient in a high humidity
enviorment
as it is in a dry climate.

Chris,
You must have been an officer or clerk. The day room
and mess hall had AC
but, us enlisted men lived in screen houses (hooches)
and air
conditioners don't cool even a 3 sq. ft. space in the
open space of a
screen house. I almost forgot, some NCOs had walls
around their quarters,
so AC was in use there. And yes I am quite sure of
what I saw over there
and I have built at least ten swamp coolers from
scratch.

Kris,
My understanding is that Evap Coolers just Don 'at' t work
in
very Humid Climates, at least to any usable degree.
The water moisture just does not evaporate out of the
air
as the air is already saturated with moisture.
It is the evaporative stage that produces the cooler
temps.
Desert Climates with very hot dry air are best suited
for Evap coolers.

Steve H,
I am still not sure about what you said,
" Can 'at' t set up an evap cooler as its to humid "
I'll rephrase. I don't understand how 97% humidity
outdoors, when sucked
through an evaporative cooler is more harmful than the
excessive amount
of heat it removes. I've been in greenhouses near
Phoenix that stay about
80 degrees F when it's a 120 outside. I mean isn't
100% per cent humidity
as high as humidity can go and is that harmful to
plants?

Subject: Re: Bilge Pump Safety - DC power
From: fishmanbruce 'at' webtv.net (Bruce Schreiber)
Date: Fri, 27 Jul 2001 20:36:00 -0500 (CDT)
Roy in my case the voltage was 12V DC from deep cycle
batteries on our
commercial fishing boat the Think or thwim in Bristle
Bay AK. A small 35
foot drift netter fishing for Sockeye Salmon .At times
we 4 crew would
pack on 16,000 lbs. to 21,000 of fish in a work day in
bad weather sort
of pushing our luck if you get my meaning had to plug
the skupers.So if
the pumps went out it quickly got sort of serious and
if the water got
to deep in the bilge from a bad switch or the pump
going bad we had to
work on them while on to find the bad spot in the
circuit or sink and in
that water you are dead in about 5 minutes on a good
day.
The 12V systems are perfectly safe to work on
submerged as long as
you can breath a little or the commercial fishing
fleets would be wiped
out in one season but I would not play with any thing
higher than about
24V .When wet a spark could blow you out of the water
if your using gas
V8s or you've got some solvent floating in your Bilge.
The fire works
can get real spectacular on the long day of summer
solstice 240hrs
long and its nice to have a little entertainment

Bennet,
I misunderstood what Doug had offered, I thought he
was going to send me
printed matter but,he sent lots of links instead. I
posted it a couple of
hours ago. See
the subject line: Resources List. I apologize for the
