Tim, Jeff & all, A good expanded message, Tim, Jeff.
At first thought it seemed right to avoid covering the brewer because collecting CO2 would be adverse to
absorbing O2 at the surface
Second thought - the prime source of D O2 is the air being bubbled thru the ACT. That always comes from fresh air outside the system. That air will release over the liquid and continue blowing away CO2, whatever is released by the herd. My guess, impossible to seal a cover tight enough to make a difference.

Second subject.
A village in Italy tapped into local hot springs, geothermal energy. They generate electric power via steam turbines, sell power in the village and beyond the village, thus support the village government ( lower taxes). The expended steam from turbines is piped to homes and green houses to heat those, condense & return water to the closed system. Clean!.abundant energy, no pollution.
Extensive green houses are heated and lighted by this clean geothermal energy from their local 'Hot mountain'. They enjoy fresh organic produce grown year around. Sounds like a great new idea?
Surprise ! They have been doing this for 100 years!! Why haven't we noticed? We have geothermal heat available all over the USA. In fact all over the world. Cheaper than coal. 50,000 times more abundant that all fuel energy, oil, gas, coal, nuke, combined. Easier to obtain than coal, oil, gas or nuke. Provides CLEAN, cheaper electric power than any fuel , nuke, water, wind or solar. Steady, 24 7 365 Forever. No limit.
EARTH is the second most abundant source of energy next to the SUN. ( With the EARTH at about a trillion trillionths the energy of the SUN or less? ) But still EARTH's GEO energy is beyond what we can ever use up. GEO is the ONLY hope of winning the Battle against pollution and global warming. Is it a secret so (who?) can sell, get rich on OIL, GAS & COAL?
We had a popular president who inspired our nation to "put a man on the moon in our decade"
Stopping global warming is far more urgent than putting a man on the moon. The important result
of the MOON SHOT? The picture of our beautiful, tiny EARTH, floating, our very own space ship,
floating alone in space. It looked so alone, so fragile! It is that fragile! And absolutly ALONE!
We inspired ourselves to win WW2. An all out world effort, both sides. Winning the battle to preserve EARTH is infinitely more important than it was to win WW2, Now both sides on ONE SIDE. WHERE is FDR when we need him ? How tragic must our Pearl Harbor be, to wake us to the importance of EARTH's climate? Tougher weather than New Orleans? Wilder Tornado's in January? Flooding all of Bangladesh? An ice free North and South pole? Millions more sq miles of ocean area? Or far worse!
With enough CO2 can EARTH begin self generation of vapor and gases that can generate the atmosphere of Venus? With that atmosphere, the infinite energy the SUN brings us will be held at Earth's surface. Thus EARTH can generate the climate enjoyed by Venus. Surface temperature, 600 d F. Polar bears in trouble?
I have yet to hear word one from '08 candidates suggesting they consider global warming of interest.
Nothing about soil conservation. Nothing about water conservation. Nothing about pesticides vs health..
Nothing about health. Just health insurance, taxes and Iraq and who said the wrong word last. Quibbling.
No significant aspiring program to do a dam thing.
This group, The Compost_Tea group, is probably among few oriented & educated to preservation of the EARTH ecology, climate. Is it our duty to think, and act beyond ACT? Don't just cross me off. We need informed, thinking citizens to lead, or prod leaders, to significant action. Bob

Hi Folks,
I'm coming in a little late on this discussion having been away at
the Seattle Garden show. Oh and I finally met Jeff Lowenfels in
person and listened to his talk on compost and brief on compost
teas. He is a very entertaining speaker and packs a lot of good easy
to understand information into a short duration. I did not see one
person sleeping (well except my dog). If you have a chance to see
him, do it!
Now back to ventilation; I completely concur with Elaine and Jeff on
this subject. Why cover a brew? You want air to get in there. Ever
heard of the gas exchange? This is where one gas is exchanged for
another. In the case of a brewer it is CO2 for O2 and unless I'm
full of pre-composted animal waste, the only place this occurs in a
CT brewer is at the surface. There are no plants or other CO2 using
life forms or substances in your brewer (that we know of) and your
multiplying microbes are busy cranking out the CO2 as they eat and
divide. For water to contain maximum dissolved oxygen(O2) the carbon
dioxide(CO2) needs to get out of the way. So if you cover your
brewer with an air restricting surface you are reducing the
efficiency of the gas exchange of your brewer. I cover my small 50
gallon brewers with a piece of white fabric when I wish to reduce
splatter. It allows passage of air and light. My 1200 gallon brewer
has 11 feet of air interface and is not covered.
Now back to Jeff; If you want a good easy to read introduction to
microbial based horticulture get Jeff & Wayne's book;
'Teaming With Microbes' I think you'll find it by googling.
The only sentence I disagree with is that peat moss is sterile. My
findings have shown that Canadian Sphagnum Peat Moss (Premier Brand)
tested in Canada and the USA at random is abundant with microbial
life. You may see some data on my website
http://www.microbeo rganics.com
I believe that the misconception that sphagnum peat moss is
sterilized before it is exported to the USA arises from the Canadian
regulation that such products being imported into Canada must have a
certificate of being inert. The USA does not have a similar
regulation in regards to peat moss.
I will endeavor to find the regulations and post them but I did
phone and ask the authorities previously and carried a lot of peat
across the border myself to pick up a load of worms.
I was actually surprised to get across the border with such a load
on my way south. Worms don't like light and so one simple way to
keep them in place is to leave a light on above them. We had loaded
about 6 plastic bins filled with wet peat into the van on partially
inflated air mattresses because worms don't like vibrations. It was
a two day trip and I did not wish to use the light in the van
overnight while at the motel for fear of killing the battery and I
did not want worms crawling everywhere. I therefore rigged up a car
battery to a light attached by wires and hanging from the back of
the front passenger seat. As I drove up to the customs guy at the
border crossing, I thought surely I look like a terrorist with
containers of fertilizer and battery and wires dangling. I expected
a thorough search, a grilling and possible refusale of entry but the
guy believed my odd story and waved me through.
Salutations,
Tim
(Was that okay Jeff? Do I still get paid?)
