Hi Red!!
Here is a link for all of those interested in
gasifiers for your
aquaponics power/CO2/heat.
http://costich.tripod.com/gasifier.htm This hombre has
done quite some
work!! He tweaks a bit with old dishes too!! Please
send some business
his way, and tell him his friends in Jamaica sent you.
He has a lot of
renewable energy stuff worth looking at.

Hi Red,
Right now, we only have the one air heater here, and
one at our daughters
house. Bill Kreamer's design using furnace filter
material as the absorber
and heat to air transfer media is what built ours
from. Each of the two
that we have built, have cost around $100.
Bill Kreamers air heater design can be found on Steve
Spence's web site,
follow the link to "Build Your Own Solar Air Heater -
Style 2"
http://www.webconx.com/2000/solar/solar.htm
This particular design of Bill Kreamers, if followed,
will prove itself. We
built to this design for the heater at our daughters
house.
One exception is, we used a differential temperature
controller that I
modified/built. Bill's design uses a thermal snap
switch, which does not
activate a blower/fan until the units temp is about
110 dF. The
differential controller senses the "to be heated
space" and the internal
temp of the solar heater. If the solar heater is
warmer than the space to
be heated, it activates the fan/blower. There are
commercial differential
thermostats available for a around $100 and up. We
were able to build ours
for about $15. If you or someone you know can do some
soldering, this
controller can be built all from Radio Shack parts.
The diagram is at:
http://www.hctc.com/~njones/solar/tempcontroller.pdf
On the other hand, you can wire in the snap switch per
Bill's plans, for
about the same price and you don't have to get into
the electronic
construction.
We also use flexible vinyl film (storm window type
stuff) material for the
glazings on both instead of rigid glazing. This
material comes in either 4
or 8 mil, and inexpensive compared to rigid glazing of
any kind. On
Kreamers design, the air duct in the center of the
unit is sealed across the
face with the plexiglass or lexan he is using. On
ours, we put a small piece
of rigid plexiglass over just this center duct unit to
force the air to the
bottom front of the heater, then just covered the
whole face of the heater
unit with the flexible film and stapled it around the
perimeter (sealed with
silicone sealer).
The one we built for use here at home, is about 30
inches tall X 10 feet
long. Still using the furnace filter material (spray
painted flat black) and
pushing about 150 CFM of air and an outside temp of 40
dF, we saw some solar
air heater temps in the 130 dF output range. Cool
house air goes in one end
and comes out the other end back into the house, only
warmer.
If you study the information at the link below, you
will find that this is
probably one of the best designs for getting heat and
hot water, without a
lot of technology. We are hopefully going to build
one of these before
winter. We were going to this spring, but things just
got out of hand here
at home with a lot of other projects. The solar
closet can be built free
standing, connected to the space or house you are
wanting to heat, or built
into the space or house. When take into consideration
the technology of
just about everything else on the market, or designed,
they either have
pumps/controls, controls/valves, complicated plumbing
arrangements, or lots
of "stuff" on your roof. The maintenance and
operation of all this "stuff"
has to be taken into consideration. Not that there
aren't probably a lot of
good systems out there, but for me this is the way to
go.

Hope this helps some

Mark,
I did a workshop at a high school in W Virginia which
had modified the
S & S system, eliminating the grid. They supplied the
nutrient at one
end of the growing bed only and had no problems with
it. This makes
seeding and clearing beds easier, provides greater
usable growing
area, requires less piping and connections, less area
for algae
build-up etc. I visit Jay Meyers at his Panama City
greenhouses last
week and we discussed this specific thing.
I am growing hydroponically and have a couple of
expanded clay beds on
a slight slope with a pipe across the high end running
at a low flow
rate and it is working out very well. The clay is
more porous however
and wicks the nutrients up to the plants. If you are
planting from
transplants where you can assure contact with the
nutrient flow
stream, gravel shoudl work OK. For surface broadcast
seed you may
have problems getting adequate moisture to the plants
for germination
and early growth using gravel.

I just thought of one potentional downside
.exposing
the water to
a lot less medium/bacteria. Delivering it from the
top maximizes
this. In my smaller aquarium system, I think my 4
bio-wheels will
compensate. Only one way to find out.

That is true, which is why flood and drain is a good
option for
aquaculture. My growing is strictly hydro so I don't
need the
biofiltration that the rocks provide.

Mike,
Any idea which species you had been handling?
Sturgeon fish have a fin
much like a sharp scalpel near the tail fin. Dorsal
fins of many rock fish
have mild neurotoxins. There is a nasty little
critter, Phisteria piscacita
(spelling is a little off) that is found on the east
coast and certainly as
far south as Florida (maybe down in the Caribbean) Its
a dinoflagette that
injects with a nemotast, a toxin that causes sores
that don't heal in in
some cases a Parkinson's like syndrome that lasts
about 6 months. It's
caused massive fish kills in the N. Carolina and
Chesapeake Bay region. A
researcher at UNC by the name of Joanne Burkholter (
I think thats the
name). Secondary infection is more of a problem. Any
allergies to fish? Any
breathing problems related to this? Anafalatic (sp)
shock is not something
to take lightly.
I saw this interesting fishing technique out of
south Carolina where guys
put their arm in the water and reach under logs and a
catfish bites on their
arm and they haul the fish into the boat. Just exactly
how much do you have
to hate your wife to fish like this?
I'd be interested to see what kind of local
treatment you get for this. We
just had a good size shark (15 ft+-) about a month ago
in 8 feet of water
right off the shore (about 50 feet) knock an adult
california Sea Lion clean
out off the water and bit it clean in two. This was in
front of a beach full
of tourists. I think that would be the ultimate fish
sting.
