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

[–] FlaminGoku@reddthat.com 8 points 10 months ago (2 children)

Most people don't have methane in their farts.

[–] blandfordforever@lemm.ee 26 points 10 months ago (3 children)

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

[–] KpntAutismus@lemmy.world 8 points 10 months ago

become a ruminant probably

[–] FlaminGoku@reddthat.com 2 points 10 months ago

Biogas generator

[–] this_1_is_mine@lemmy.world 1 points 10 months ago

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

its super effective.

[–] SimonHoogwerff@feddit.nl 5 points 10 months ago (1 children)

What makes farts flammable then?

[–] FlaminGoku@reddthat.com 4 points 10 months ago (1 children)

Methane. Not everyone can light their farts on fire.

[–] murmelade@lemmy.ml 5 points 10 months ago

Poor bastards

[–] theodewere@kbin.social 61 points 10 months ago (1 children)

"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

[–] TheBatz@sh.itjust.works 1 points 10 months ago (1 children)

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

[–] platypus_plumba@lemmy.world 12 points 10 months ago (1 children)

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

[–] TheBatz@sh.itjust.works 4 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.

[–] Jazsta@lemmy.world 57 points 10 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.

[–] BestBouclettes@jlai.lu 21 points 10 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.

[–] porotoman99@lemmy.world 2 points 10 months ago (3 children)

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

[–] Daxtron2@startrek.website 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

[–] sukhmel@programming.dev 4 points 10 months ago

Reminds me of this a bit recursive trolley problem

[–] miss_brainfart@lemmy.ml 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.

[–] Luvs2Spuj@lemmy.world 23 points 10 months ago (1 children)

Can it be monetised more than destroying the environment though?

[–] commanderbalok@lemmynsfw.com 11 points 10 months ago* (last edited 10 months ago)
[–] galoisghost@aussie.zone 31 points 10 months ago (1 children)

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

[–] ICastFist@programming.dev 11 points 10 months ago (1 children)

Probably just a big pad over their asses

[–] zcd@lemmy.ca 6 points 10 months ago (1 children)

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

[–] PlantJam@lemmy.world 11 points 10 months ago

The rear two plus suspenders, obviously.

[–] HubertManne@kbin.social 13 points 10 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.

[–] Railcar8095@lemm.ee 4 points 10 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.

[–] HubertManne@kbin.social 0 points 10 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.

[–] MonkderZweite@feddit.ch 11 points 10 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?

[–] huginn@feddit.it 30 points 10 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.

[–] Xtallll@lemmy.blahaj.zone 17 points 10 months ago (3 children)

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.

[–] Mr_Blott@lemmy.world 19 points 10 months ago (5 children)
[–] Excrubulent@slrpnk.net 18 points 10 months ago* (last edited 10 months ago) (1 children)

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

[–] Mr_Blott@lemmy.world 2 points 10 months ago

Give me washing machines or give me death

[–] barsoap@lemm.ee 7 points 10 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.

[–] agent_flounder@lemmy.world 2 points 10 months ago

I believe that's 80 stone

[–] bronzle@lemm.ee 6 points 10 months ago (1 children)

Not a fan of kilopounds, klbs?

[–] platypus_plumba@lemmy.world 2 points 10 months ago

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

[–] SimonHoogwerff@feddit.nl 4 points 10 months ago

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

[–] KairuByte@lemmy.dbzer0.com 0 points 10 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.

[–] sukhmel@programming.dev 1 points 10 months ago

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

[–] Rhaedas@kbin.social 10 points 10 months ago* (last edited 10 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.

[–] Lophostemon@aussie.zone 4 points 10 months ago

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

[–] MonkderZweite@feddit.ch 1 points 10 months ago* (last edited 10 months ago)

Guess i remembered wrong.
