power cows

would a cow by any other name still smell as rank?

Ok, this idea is a little grody, but I think it has merit as an applicable technology for dairy farmers and cattle ranchers. I’m talking about methane collection systems for livestock.

Whether we like it or not, cattle nowadays are pretty much an automated species, it shouldn’t be that hard to get them used to wearing saddle bags, which would house a flatulence activated vacuum apparatus, these would then collect the lighter than air gas through a nozzle attached to the base of the cows tail. The electricity needed to run these devices could be provided for by harnessing each animal’s movements while walking.

The number of uses for methane gas on a farm, (or anywhere for that matter), are staggering, and this would go a long way toward minimizing the excess greenhouse gas emissions created by livestock ranching. It would also be a cost effective addition to the industry, because the animals would literally be heating and lighting their own barns in the winter, producing the electricity to run their own milking machines, and perhaps, even enough power to supply the electrical needs of the ranchers own home throughout the year.

       thought this said "poorer cows"   

       I was always led to believe that grass-munching herbivores did not smell anything like as bad as carnivores <looking oddly at 2fries as she speaks>

       Actually po, I can assure you, 300,000 head of dairy cattle emit quite a stench. Where I grew from a mere stubwax into the mighty thumbwax - is now the USA's #1 Agricultural producer - chief among those hundreds of crops/commodities is milk - (2001 saw the county of Tulare reach 1.15 billion dollars of dairy production - through the grapevine, local yokels claim this to be the first time *anywhere* the billion dollar figure has been attained for any commodity in a single year).

       It is my understanding that livestock pretty well heat their own quarters with body heat, and also that the majority of the methane is emitted from the front end, as belches.   

       A system for extracting methane from the barn exhaust ventilation might be workable.

       imagine the stench from 300,000 british men after a night of beer and curry. sorry, good doctor.

       So that's where all the fog comes from, eh?   

       I like the name power cows.

       //bulgy bear// Good link, It gives me a warm and fuzzy feeling knowing that someone is seriously thinking of utilizing this resource. Although it does not bake this idea, they want to extract the methane indirectly from the manure piles, and not from the animals as they produce it.   

       This has been Baked for twenty years (I recall a Tomorrow's World segment on it from way back when). (Link to a current version for the egnostics.)

       Ah, but that is produced from the shit of the cows.
This [link] is what I'm talking about.
