I have two buckets fermenting actively in a chest freezer with a space heater inside
to maintain temp. I bent over it to check something, and could definately feel the CO2
in the freezer. It even burns my eyes. I had to find out if it was really the CO2 that I felt,
so I tried lighting a match and lowering the flame into the freezer. Sure enough, 6-12 inches
below the top of the freezer, the match goes out - no oxygen. I find it amazing how much
CO2 the fermenting wort produces.
So - if they start making large amounts of alcohol for automotive fuel, will that increase
the problem of CO2 as a greenhouse gas?

Were that to happen, wouldn't the rainforests love it, since plants
"breathe" CO2, and expirate oxygen? Perhaps by brewing more we're saving
the rain forests?

Yeah, except they are chopping that down to grow cattle (more methane).

CO2 is a natural and unavoidable by-product of fermentation.
Whether it would increase the global CO2 levels depends on
how much CO2 we don't make from burning the petroleum it
replaces. Same problem exists when cracking hydrogen from
natural gas. Of course if we started using muscle power only
that would increase the need for food which would lead to
increased production of methane.

I generate enough methane sitting around with a beer in my hands.
Don't need to do anything to make more.

Or we could build some breeder reactors and eliminate the CO2 as well
as all our nuclear waste we have sitting in storage.

There's a formula for calculating CO2 release from beer fermentation.
Something like 1 cu.ft. of CO2 for every 1 degree drop in gravity per
5 gallons of wort. It's quite a lot when you brew commercially. The
fanatics don't seem to have picked on the brewers yet!

They tried stopping alcohol before.. didn't work out so well.

It will not increase CO2 at all because it is a sustainable cycle.
The plant absorbs CO2 during it's growth. When you utilise the plant you
release the CO2 back into the atmosphere. It's part of the carbon cycle.
Burning and releasing CO2 which has been locked up for millions of years
(oil, coal, natural gas) is the culprit for increasing CO2 levels.

Bob,
Why do you have a space heater in a chest freezer?

To warm it to 68F for fermentation. Ambiant in my basement is 58 or so.
