Can Cow Backpacks Reduce Global Methane Emissions? (bloomberg.com)
Slashdot reader schwit1 shares an article from Bloomberg which argues "It's time to have a conversation about flatulent cows."
"Enteric fermentation," or livestock's digestive process, accounts for 22 percent of all U.S. methane emissions, and the manure they produce makes up eight percent more, according to the U.S. Environmental Protection Agency... Methane, like carbon, is a greenhouse gas, but methane's global warming impact per molecule is 25 times greater than carbon's, according to the EPA.
Cargill has tried capturing some of the methane released from cow manure by using domed lagoons, while researchers at Danone yogurt discovered they could reduce methane emissions up to 30% by feeding cows a diet rich in Omega-3 fatty acids (mostly from flax seed). But now Argentina researchers are testing plastic "methane backpacks" which they strap on to the back of cows, and according to the article "have been able to extract 300 liters of methane a day, enough to power a car or refrigerator."

The majority of methane from bovines exits from the mouth, not the rear end. Why do these morons not take a few moments to learn about the beasts before coming up with their idiotic ideas?
This bullshit (no pun intended) is getting ridiculous now. There is no such thing as 'catastrophic man-made global warming' (renamed 'climate change', which means nothing, since the climate is always changing, yet is ALWAYS meant to be taken to mean 'catastrophic man-made global warming'...)

All of the 'scientists' promoting the LIE of 'global warming' benefit financially from their LIES.
Really.
Cow meat is bad for you (heart disease, stroke, cancer, etc.) and raising cow meat is bad for the environment.
Just stop eating cow meat... problem solved.

Sounds like a load of hot air to me.
Let them eat grass.
Say moo, moo you farty cows. Fart more, mooBoy!
Then the entire herd explodes
Problem solved.
Factory farms are about to drop the "farm" and become ground-beef printing operations. Only perhaps ten years off.
It's interesting to learn about the noble gas Carbon......
What about cow jetpacks? Now that will be worth doing.
Keep coming up with ideas like this. "Deniers" love this sort of thing.
Look you can be vegan or whatever if you want, but I think I'll take the risk and eat my juicy barbecued steak. As for the methane : it contribute only roughly 25% of the warming that CO2 does. The reason are simple : the half life of methane in the atmosphere is short and the quantity of methane are 1/200 of those of CO2. And then enteric fermentation is barely above 16% of total methane emission (all farm animals counted, not only cows). Coal mining , oil drilling and treatment is above that , about 19%. Then there are other sources, rice cultivation (12%), waste treatment and landfill (12%), burning of biomass (9%) look up wiki if you wish for more details and more importantly : the sources of citations. Sure we should keep in check, as long as we don't concentrate on "cow" and follow other venue , like reducing coal and oil CO2/Methane emissions.

We all know the backpack idea is bullshit, but at least it is raising some serious discussion about the scale of pollution due to industrial agriculture. The only solution is to cut back on meat consumption, but Cargill won't be issuing that in a press release any time soon.

I don't know very many farmers that would be terribly excited about putting a cannula into their livestock's digestive tracts.

In what world is 300 litres (presumed at STP) per day of natural gas enough to power a car? Even in something rather efficient like a Honda Civic, that's still only enough for about 5 km per day, or ~2000 km per year.
[300 L/d of methane] * [0.0364 MJ/L of methane] / [34.2 MJ/L of gasoline] = [0.319 L/d of gasoline equivalent]
[0.319 L/d of gasoline] / [6 L / 100 km (fuel economy of a modern compact sedan)] = [5.32 km/d]
According to the estimates of the INPE researchers, dams are the largest single anthropogenic source of methane, being responsible for 23% of all methane emissions due to human activities.

Thus irrigation for crops is worse on the environment than cows.
Some drink at the fountain of knowledge. Others just gargle.
There is good evidence that vegans have higher rates of mental illness - the question is if it is a cause or an effect?

Also - from the abstract : ...Moreover, our results showed that a vegetarian diet is associated with poorer health (higher incidences of cancer, allergies, and mental health disorders), a
higher need for health care, and poorer quality of life. Therefore, public health programs are needed in order to reduce the health risk due to nutritional factors.

Methane added lasts about 8 years before leaving the atmosphere. CO2 lasts orders of magnitude longer. So, while it would produce a noticeable effect to cut the methane, at this point we're just replacing 2008's methane (maybe a little more, I know the number of cows has gone up post recession, but I don't know if it fell during the recession.)
Your ad here. Ask me how!
Won't be long before the environuts propose this for humans
Man, it is a good thing we shot all the buffalo. Imagine how much methane they would have released...
Excuse me, but please get off my Pennisetum Clandestinum, eh!
Livestock displace the billions of wild animals we slaughtered.
Does cow fart really contain that much more methane than buffalo fart?
is best adapted to eat, instead, like grasses,
I'm blowing my chance at moderating this story, just so I can say this: There's not a damn thing you can say or scientific study you can point to that will make me stop eating meat. Even if it meant becoming a "second amendment person" (thanks, Trump) and hunting animals, I would. I could watch a PETA "Meat is Murder" propaganda video while chomping down on a burger and it wouldn't faze me in the least. Like religion and most republican policies, my decision to eat meat isn't based on reason or logic. It's based on a deep carnal desire to devour animal flesh, compounded with my belief that it's also delicious.
If you truly were satisfied with your lifestyle choice, you wouldn't feel the need to seek validation by attempting to convince others to come to the same conclusion.
Now if you'll excuse me, I have to go put a "I'm with Her" sticker on my economy car, and then order some meaty Tuscan pasta on my iPhone from Pizza Hut.

DRM is like antifreeze, to the MPAA/RIAA it's sweet, to the consumers it's poison.
Australian researchers have developed an inoculation against some of the most common methanogenic bacteria found in sheep, supposedly reducing their methane output by about a third. It also makes a small amount of extra food available for the sheep to utilize. I don't know if this has made it out of the laboratory and into farms as yet (if ever).
How about paying for the abysmal eco-balance of meat production with a tax on meat instead of such harebrained ideas.
After all, we tax gas and cars, don't we?

Blaming carbon dioxide on agriculture is just a distraction.
But caws do not know how to drive !

From the summary:
Methane, like carbon, is a greenhouse gas
Carbon is a solid, not a gas.
A molecule of methane includes carbon.
Or, is carbon now synonymous with carbon dioxide?
Not an expert on bovine methane emission, but globe-trotting, jet setter eco millionaires (and their tools) junketing the globe lecturing the 99% on what type of food is sustainable is not sustainable.
"I now inform you that you are too far from reality."
You know how they say that in ancient times, hunter-gatherer societies used all the parts of an animal? Very soon we can put them to shame. :-)

Someone please feed this vegan to the wolves before it finds our steaks!
I would have thought meat came later,anyone living near water would have been eating shell fish and fish etc,as well as seaweeds etc.
I thought the latest theory is that early man navigated around coastlines,rather than trek across expanses of unknown territory,where you might find something to eat tomorrow,or you might not,compared with coast lines where you have to be very unlucky not to be able to find something to eat..
All this worrying, so little time.
Eat a cow! Quit fucking slackin.
Methane, like carbon, is a greenhouse gas, but methane's global warming impact per molecule is 25 times greater than carbon's, according to the EPA.
I assume they mean carbon dioxide, right? Because if they're talking about pure carbon, I can't imagine it stays airborne for long enough to have much of an impact.
Maybe that's why it's so much less effective than methane.
Just FYI, they surgically attach the piping to the cow's stomachs.
Not me, you have to hook up the hose that connects the cow to the backpack.

Prevention is better than a cure.
As a testing method perhaps the backpack makes sense, but as a real world solution I doubt surgery on billions of cattle is all that viable. Most farm animals are raised in large canvas barns anymore here in the US. Methane also has a tendency to rise, so simply design the airflow of the structure to allow the methane to concentrate in a holding area at the top of the structure, pump it off into holding tanks and use it for something.
I'm sure that the average politician emits at least 3 times the methane of the average cow.
Slow down, cowboy! It has been 4 hours since you last posted. You must wait another few hours.
Gassy cows come from being fed rich grain. You can solve the problem by letting them eat the grasses for which they were designed. This is a lot cheaper solution. Healthier too.
I call BS on any person who claims: "We" need to do more about global warming... and at the same time includes beef or dairy in their diet.
Bonus points if they collect enough methane gas to power their own slaughter and delivery...
