I have some full-sized Bright Lights Swiss Chard which is just about
ready to sell. Does anyone have a sense of what the market can bear for
it? Our nearest wholesale market is an hour away and I don't think
anyone else is offering anything like it in this area. Local growers
are few and far between so I can charge higher than "market" but don't
want to go so high as to turn off buyers. I would appreciate any frame
of reference you guys can offer.

Hi gang,
Just got back from the long(er) weekend and saw the postings on OTEC. I've
done a little
work with the good folks on the Big Island and can say that the implications
for aquaculture
are ENORMOUS. However, to fully re-create the Hawaii OTEC one needs to be
situated very
close to a coast line that has very deep water close by. The deeper water
is colder-- OTEC
is typically based on the temperature difference between surface and deeper
waters. The
bigger the difference, the more efficient the energy production. Their web
site is
http://bigisland.com/nelha/ As far as aquaculture is concerned, one
organization based
there uses the cold, nutrient rich water to produce spirulina algae,
certified organic, and
is now a multi-million dollar publicly traded company. There are at least a
couple dozen
companies based at the Hawai OTEC facility, most seem to have met with a
fair degree of
success.
Happy hunting.
Mark

Has anyone grown the above in an in-house aquaponic system? Perhaps this
coud be integrated into our small marshes and fish aquariums of our
greywater treatment system? Perhaps our GreyWater GardenWall could
also grow these as food for people and marine life? BTW, our crayfish
were able to reproduce even with the hardships of household graywater.
None of our marine lifeforms (snails, fish, crayfish, etc.) have ever been
feed store bought food. They just get dish water, kitchen scrap and
greywater. One of our water hyacinth is blosoming a pretty blue and our
pear shaped tomatoes in our hydroponic section is turning a beatiful
golden colour, thanks to some kind friends (noted above) who helped on
this project.

Ted, tilapia feed on plankton not by gill rakers but by mucous in their
buccal gavity. Fine particles stick to the mucous which is swallowed.
One secret to greenwater tank culture is removing sludge. This is not only
feces but dead algae. As phytoplankton populations collapse they settle out
and are immediately removed from the system, rather than decaying,
consuming oxygen and producing ammonia. For days there may be very little
sludge and then for several days we will collect 10-20 times the normal
amount of sludge. Algae limits itself through cycles of growth and die-off.
The second secret of greenwater systems is feeding so much that you
transform an algae-based system into a bacterial-based system, so when
algae does die, the bacteria still continue to remove ammonia. Of course,
abundant aeration is needed.
Uwe, dilution is not the solution this time. We did an experiment where we
diluted 5% every day compared to no dilution at all and it made no difference.
Adriana, don't forget that your perlite system has no fish. I'm not
convinced that perlite set up as a continuous flow-through hydroponic tray
will work in a closed warmwater (>80F) aquaculture system operated at
commercial fish production levels, even with great solids removal. There's
very high levels of dissolved organic waste in closed systems that
stimulate the growth of heterotropic organisms, whose growth could gel and
channelize the perlite bed. Let me give you example. We once had 3-inch
rearing tank drain lines with a flow rate of 12-15 gallons a minute and
they clogged due to the prolific growth of filamentous bacteria.

Hi Paula,
looks like my glass ball is up and running again, because I correctly sup=
posed that you would give me the answer.Thanks alot, Paula! And how do =
you get along with more than just one grandson/daughter at a time? I need=
to know, because I'm going to see my first (2 1/2 years) and second (2 =
days) grandson pretty soon...

_____________________There was a German,
Saurbrauch I think, who in the 20 years before W.W.II did a lot of work
on the principles of living water, vortices, natural energies
etc..including Rudolph Steiner's Biodynamic principles.
An uneducated woodsman, he perplexed "normal" scientist with practical uses
(water logging runs) that defied "science".
I read a book about him, weird and fascinating subject, he invented a
working model flying saucer, hazy blue light and all.
Also vortex aerating devices that would likely be suitable for the group's
interests.
At the end of the war his work was seized by the American Military, or so
the book said. (But please no connections to Area 51 on this list.)
I wonder if this stirs any memories out there ? I am not certain of the
name Saurbrauch though.I got the book from the library and will try to take
it out again.There was a sketch of a Vortex aerator in it,highly efficient
and very simple, but that's all that's strictly relevant...
What about Rudolph Steiner's work applying to our subject, anybody know
anything ? Vortex aerators ?
Oh, sorry .
Hello to all, been lurking awhile. Nice group.
Only an observer, I am stuck in a basement apartment in London. UK._and even
the Cactus died. Still I dream of the Farm, the Homestead, it was all those
Westerns....________________________

I believe the mans name "living water guy" was Viktor Schauberger..
A book " living water" was written by Olof Alexandersson
ISBN 0 946551 57 X
copyright 1976 , publisher Gateway Books, The Hollies, Wellow
Bath, BA2 8QJ (is that England?)

Carolyn,
The linear motor in fact uses magnetic energy to remain in perpetual motiom.
When I find my notes and an URL I will forward it to the group.

Jim, I guess I was out to lunch on that one...Typing faster than I can
think, I guess.
The old gears in the noodle box are getting rusty from abuse and disuse, I
suppose.
What critter was I thinking about? Polyodon spatula? I've been around a lot
of paddle fish, in my checkered career, that is for sure...At least
nowadays, I have a more gustatorial relationship to Tilapia than, uh, an
anatomical relationship. .
Anyway, Tilapia can derive nutrition from fine particulates and suspended
matter in the water. How's that?
Cheers,
Ted.

>>>tvoivozhd---the linear motor in fact does not use magnetic energy to remain
in perpetual motion. There is a $100,000 prize laying out there for a motor
that does. There is no danger of the donor having to pay it out.
