thanks horst -
i wasn't sure about the protocols for contacting research folks.
The few times i have bothered university/research people with my naive
questions i didn't recieve a reply. I assumed it was because i wasn't going
through the right channels, or that basically they were too busy, - who
knows. . .But i'll give it a try..

You said:"We harvest the excess biomass periodically, some for human food,
some for animals, and some for compost/vermiculture."

system. Which plants do you use for the purposes described above,
especially human food and compost? Jorg Ostrowski

Yesterday I received "Methane Recovery from Animal Manures, the Current
Opportunities Casebook" from Philip Lusk at Resource Development Associates.
If you are considering anaerobic digestion, this is a great resource.
Funded by the National Renewable Energy Laboratory in Golden, Co. , this
report coves the current status of biodigesters in the US and gives detailed
financial and through-put case reports on currently operating ones. These
are all farm units with capital costs of $80,000-$500,000, which is a bit
large for a small farm application, but the demand isn't there yet for
smaller units. It gives an excellent history of the problems encountered
with the units and how they were solved or why the units were abandoned.
There is also a list of consulting engineers and companies.
Philip Lusk can be contacted at:

so yur gonna sink a few sleepers as stakes , on the perimeter, backed up
at their feet w/ more sleepers buried at grade behind the stakes
compacting the dirt behind these "braces", also at the foot of the
stake, compaction is warranted....sounds doable..then laying horizontal
and overlapping more sleepers for the walll...stucco chicken wire, more
plaster, then liner, dad gummit giddy up...how long are the sleepers?

Each sleeper is about 6 inches in thickness and spans a distance of about
five feet.. Some are bigger, and span 10 or so.

Hey,
I noticed an increased interest on the list in using methane for pond
heating, greenhouse heating, etc.. so, I thought I'd make available all of
the info I have found.
Dave Paxton's Biogas Series (47KB Text) -- very, very old Fidonet posted
series of articles is very concise about making cheap biogas digesters,
etc.. I will e-mail this to anyone for free, as always.
I also still have the pop bottle plans, if anybody still wants them.

Dear Jilly and Lars,
I have been a university/research person all my life. You know, we are only
humans as well. There are those and there are those, like in every sector of
the community. You can even see that in this discussion group over the past
months. The importance is to find eventually a person who helps.
Hope you have luck

The nutrient-rich ponds of reclaimed water need a plant covering of about
30-50%. If you cover too much of the pond, sunlight can't warm the pond
nor provide Oxygen through algal photosynthesis. If the cover is too
sparse, the phytoplankton bloom too fast, shooting pH high enough to kill
most fish.
We grow:
o- Tons of water hyacinth, feeding about 5% to chickens, and the rest to
compost and worms;
o- Duckweed, Same As Above
o- Azola, S.A.A.
o- Tons of Chinese water spinach (Ipomia aquatica), selling and eating the
harvested leaves and stems, feeding the rest to chickens and compost;
o- Watercress, selling and eating the harvested leaves and stems, feeding
the rest to chickens and compost;
As with fish, the choice of plant(s) is up to the pond microclimate. One
pond has very little shading from trees or hills, so it stays warm enough
all year to keep some hyacinths alive through the winters. Other ponds are
so shaded in the summers that we usually let pockets of watercress
over-summer in a corner. In our summers, water spinach and hyacinth grow
best. In winters, watercress and duckweed grow best. In springs, azola
and watercress fight it out.
Ipomia aquatica or Chinese water spinach is a very tasty leafy green. It
tastes similar to terrestreal spinach, but without any bitterness. We
bought ours at an Asain market. It retails for about $3.95 per bunch.
During winter, we floated them in pond water in a sunny window, letting
them grow roots. Once spring was here to stay, we planted them along the
eastern shore of a pond, and trained them into the water. As the water
spinach grew out onto hyacinths and other floating plants, we removed the
othe rplants in stages. Soon, the spinach was the only plant on the pond.
When cool weather returns, cut the plants back and build cold frames. If
we had a better way to market it, we could have sold lots.
Our school is revamping the farm store, so maybe this summer they can stock
our spinach and fish. All they carry are our herbs, teas, vinegars, and
vegetables. They don't have a refridgerated produce case, yet.
There ya go,
Fred

Hello Michael,
I'd like to see your plans for the pop bottle setup and the biogas digesters
if I could. Please e-mail it to my work address
joel.r.carroll@boeing.com
Thanks a lot,
