Methane does not harm the ozone layer. It is a greenhouse gas. In fact, methane from the guts of domestic cattle (and other sources such as rice crops, etc) represents a significant proportion of contribution to global warming.

Some people enjoy the added benefit of adding cigarette smoke to the air that has already been pukified by the gaseous smells of poo.

I don't think so....when you talk water evaporation, Cardon, and Little oxygen comes out never has methane come out of a persons mouth... methane is what come out of human fart i think its impossible.... I hope that answsers your?

I don't know, but your farts sound delicious. Maybe I'll hire you to just sit in my car and fart all day instead of buying an air freshener!

It depends on the permeation time of the smell (ie. dense gases spread faster in a closed environment than less condesed ones.)  Wind helps as well if it is an open environment.\n\nTo put it simply smell has too many variables to create a unified theory of odor permeation.\n\nBut I do know my farts seems to move fasters than other odors.

Yes many a times fart sound like words. Its like imagining shapes in the clouds. You hear what you want to hear. If you are about to propose you hear 'YESSSSSSSSS" farts, a child is asked about a sheep, he hears the 'BAAAA' farts, if u are seeing a film on snakes u hear 'HISSSSSSSSSSS" farts

What makes farts stink? \n\n\nThe odor of farts comes from small amounts of hydrogen sulfide gas and skatole in the mixture. These compounds contain sulfur. The more sulfur-rich your diet, the more sulfides and skatole will be produced by the bacteria in your guts, and the more your farts will stink. Foods such as cauliflower, eggs and meat are notorious for producing smelly farts, whereas beans produce large amounts of not particularly stinky farts.

HVAC OUTLETS- I assume you mean the fart fan from the restroom or some other air exhaust because nobody would be stupid enough to install a heat pump in that climate unless it was designed in Texas.  If I were you I would think about lowering the relative humidty of the air leaving as it is condensing and then freezing on the freezing outside surfaces or heating the outside surfaces periodically.  I wonder if there is like an economizer box you could put on it and then just periodically heat the inside of the economizer box.  \n\nYou could take an old breadbox like my grandmother used to have and stick an old '57 chevy radiator in it.  Let that part be outside and where the water vapor in the exhaust vent would condense and freeze on the fins on the radiator.  Then every once in a while, you could run some hot water or light some of those farts and run the exhaust gases through the water side of the radiator to defrost the coils.\n\nBut that brings up another issue as far as risk assessment.  I saw some internet videos of people blowing up from trying to light farts- its a cheap source or heat but the safety people dont like it cause someobdy might get hurt and the environmental people dont like it cause they have to fill out a bunch of EPA paperwork to get a permit to operate a hazardous waste treatment facility.  \n\nGood luck and dont eat the yellow snow cause there might be some husky dogs in the neighborhood.

It's funny and let's be honest, we enjoy doing it. The louder the better....at home of course. It is healthy to release toxic gases.
