Dry Ice

[NOLAsailing]

I need ice cream to make Bushwhackers and I need dry ice to keep the ice cream frozen when the temps are near 100. If I have to choose between Bushwhackers and asphyxiation, I'm going with the frozen beverage.

Global Warming?? You mean, it's actually, scientifiacllly, true?!?

Sorry Cam, couldn't resist.

Here's the "green" solution to the Dry Ice problem: Sit a nice leafy green potted plant on the floor next to the icebox to offset the carbon emissions and render your icebox carbon neutral!! It could even be watered from the drain..

Tada!.. Problem solved.

Doesn't dry ice equate to a irreversible case of dry mouth?

Very sure. He makes wines, and his meter wasn't working when he descended into his cellar during the fermentation phase. A couple of breaths and he was close to unconsciousness and barely made it back to the top of the stairs. It turns out that a main fuse had blown and that the ventilation and alarm were somehow on the same circuits - so I shouldn't have said "faulty", just "not turned on"

Carbon monoxide is not a by-product of fermentation. Carbon dioxide is. Note in my original post I stated that the CO2 displaces oxygen.

Sure it does.. and boats have bilges where oxygen isn't much help to anything other than a few sea creatures that might otherwise rot, so, to my small mind, a small amount of CO2 isn't going to be a bad thing - unless you're in the habit of sleeping on the floor.

Uh oh - you got me on my soap box...

I participate in a lot of discussions with other small boat sailors and a lot of them talk about "going green" by using electric motors, which they recharge with power from the mainland grid. The tie in here is that using ice and dry ice is actually extremely inefficient - the energy used to produce it, transport it and keep it cold until you buy it far exceeds the energy it would take for you to cool it if you had a little freezer.

This boater has gone all electric to limit pollution at Lake Mead:



Oops - wrong picture - or is it?

And yes I understand that a lot of people are using solar, wind and water generators. My nearest power plant is actually nuclear - not sure if that is green or not.

BTW - true confession - I am thinking of going electric but for practical reasons having to do with dependably getting away from the ramp and not having to stow gas or a gas motor on such a small boat (when trailering or leaving it unattended, locking the motor in the cabin is a good idea).

So the CO2 will settle in the bilge and in small quantities maybe okay provide you get fresh air into the cabin, but what about depleting the oxygen and the damage that could cause to stainless tanks and other stainless parts?
What is the risk to my stainless tanks welds?

It is used in winners all over the world, most wineries have nothing but stainless steel. Many of my tanks were 2000 gallons plus, I never worried.

But a wine cellar doesn't have salt residue mixing with the stainless steel. Wouldn't salt/chloride plus the lack of oxygen add the chromium depletion and stainless rust? I would thing a good bilge blower would be needed to vent fresh air and oxygen into the bilge when dry ice is vented below.
