I'll take two; one to put in my bed and one for my underwear

Most people don't have methane in their farts.

[–] [email protected] 25 points 11 months ago (3 children)

You seem knowledgeable. How can I increase my methane output?

[–] [email protected] 8 points 11 months ago

become a ruminant probably

[–] [email protected] 2 points 10 months ago

Biogas generator

[–] [email protected] 1 points 10 months ago

Eat a cow whole.... I'll give you my fork .....

its super effective.

[–] [email protected] 5 points 10 months ago (1 children)

What makes farts flammable then?

[–] [email protected] 4 points 10 months ago (1 children)

Methane. Not everyone can light their farts on fire.

[–] [email protected] 5 points 10 months ago

Poor bastards

"Today's livestock farms are high-tech facilities where ammonia is already removed from the air. As such, removing methane through existing air purification systems is an obvious solution,"

sounds like it will be something they can just add to existing systems at big livestock operations, and the removal rate is pretty high

[–] [email protected] 1 points 11 months ago (1 children)

I feel like this will cause a huge "rebound effect" (not sur if it's the correct translation)

[–] [email protected] 10 points 10 months ago (1 children)

You could elaborate your point instead of using a word you're unsure about.

[–] [email protected] 2 points 10 months ago

Sure, reducing the methane emissions of a few farms might lead to an increased consumption of meat. Which would annihilate the positive effect brought by such innovation.

[–] [email protected] 57 points 11 months ago (1 children)

Really exciting development for the climate change mitigation toolkit. Let's hope it's not too challenging or costly to scale up and deploy.

[–] [email protected] 21 points 11 months ago (1 children)

I still feel that these will be used in place of structural changes and we'll just end up polluting more.

[–] [email protected] 2 points 10 months ago (3 children)

Does that really matter if there are proper systems to deal with the pollution?

[–] [email protected] 7 points 10 months ago (2 children)

Yeah because it's not fixing the problem, really it's just passing it off to a future generation

[–] [email protected] 5 points 10 months ago

Reminds me of this a bit recursive trolley problem

[–] [email protected] 3 points 10 months ago

Combatting symptoms is nice and all, but ideally you'd want to remove the reason these symptoms exist in the first place.

Can it be monetised more than destroying the environment though?

[–] [email protected] 11 points 10 months ago* (last edited 10 months ago)

Now a meme with real world applications. How would livestock wear pants?

[–] [email protected] 11 points 11 months ago (1 children)

Probably just a big pad over their asses

[–] [email protected] 6 points 11 months ago

But only over the rear two legs? Or all four legs?

[–] [email protected] 13 points 11 months ago (1 children)

It converts it to co2 and its a structure like carbon capture stuff. Im not big on carbon capture but if you running this thing anyway it might make sense to run the output into some carbon capture scheme as it should reduce both the production and running energy since it can use some of what this is already doing as far as pulling in and exhausting the air. might be good for the exhaust to go down an old well or something to.

[–] [email protected] 4 points 11 months ago (1 children)

Not sure if there is much chance for effective carbon capture. The article states that this works for getting rid of very low concentrations of methane (so burning is not possible). That means that even with the methane 100% turned into carbon, we are talking about very small concentrations.

[–] [email protected] 0 points 11 months ago

well there would be the native co2 in the air its taking in too. My point is if it was worth it enough to do on its own its already done most of the heavy lifting so I bet if a carbon capture technique was worth it, it would be riding the output of this.

[–] [email protected] 11 points 11 months ago (2 children)

Over a 25-year period, though, methane is 85 times worse for the climate than carbon dioxide.

Doesn't it get reduced in the athmosphere in about 5 years to mostly CO2?

[–] [email protected] 30 points 11 months ago

Yes but the heat it retains in that time is 85x the effect of base CO2, which makes sense: decomposition of the methane releases energy. It does a much better job of reflecting the IR until it breaks down, then in the act of breaking down releases energy.

The atmospheric half life of methaine is just under 10 years. So if you release 1k lbs of methaine in 10 years there will be 500 lbs left 10 years after that ther will be 250 ect.

[–] [email protected] 19 points 11 months ago (5 children)
[–] [email protected] 18 points 11 months ago* (last edited 11 months ago) (1 children)

1k lbs is a perfectly cromulent unit of enbiggenment, colloquially known as "Calebs".

[–] [email protected] 2 points 11 months ago

Give me washing machines or give me death

[–] [email protected] 7 points 11 months ago (1 children)

Indeed that's 10 hundredweight. Which maybe ironically enough is rather intuitive for me, Germany still uses pounds and hundredweight (Zentner) in informal and sectorial use, meaning 500g and 50kg.

[–] [email protected] 2 points 11 months ago

I believe that's 80 stone

[–] [email protected] 6 points 11 months ago (1 children)

Not a fan of kilopounds, klbs?

[–] [email protected] 2 points 10 months ago

It's a good replacement for the heavy-fridge unit.

America is slowly switching to the metric system: metric pounds, metric feet, you know...

[–] [email protected] 0 points 11 months ago (1 children)

I mean, it’s more clear than 0.5 tons, since “tons” doesn’t specify US or metric. Not that it would matter in this specific instance.

[–] [email protected] 1 points 10 months ago

But if it doesn't matter, what's the problem with tons?

[–] [email protected] 10 points 11 months ago* (last edited 11 months ago) (1 children)

It's complicated. The breakdown of methane in the atmosphere depends on hydroxyl radicals that are created at a regular rate. If you have more and more methane released, and/or you have other chemicals that also react with those radicals, the overall average half life will increase. Both those things are happening, so the old half life really isn't as accurate as it used to be. Guess which number the IPCC still uses for its models though.

[–] [email protected] 4 points 11 months ago

Goddam Hydroxl Radicals keep sending drones to attack US ships! Iran needs an ass-kicking!

[–] [email protected] 1 points 11 months ago* (last edited 11 months ago)

Guess i remembered wrong.
