What if we collectively pee in buckets (to not dilute it with water and other human by-products) and give them to refineries for purification? /s

> 2022 And that was specifically due to the (ongoing) Russian Invasion of Ukraine. After the 2022 spike, most large countries began building alternative supply chains to reduce impacts from these kinds of hits. For example, the US and Europe largely doesn't use urea unlike Brazil, India, and China. This is also why Asian countries have been investing heavily in Hydrogen energy despite HN's hate boner to the technolog…
The Economist was recently citing hydrogen as "deep tech" [1] (meaning long R&D cycles, sometimes unproven techniology no short term profitability, heavy investment, industry-wide transformative power). Most of your sources have plans focused on hydrogen production, but I'd be interested to see specific targets or plans regarding specific uses like fertilizers. There are some in the Hydrogen Roadmap Europe, but it se…
It's primarily in Asia and North Africa. For example, India has begun building a 7GW green hydrogen project specifically for urea production [0] and as a technical demonstration. An Egypt-Germany-Norway JV is also expected to be completed by 2027 explicitly for this usecase [1]

My first thought from this is that (if my napkin math is right) I'm apparently pissing away a penny a day.
There was a time when leather tanners used to collect the urine from bars - I guess the tanners paid for it.

So, better to power the ammonia plant with clean electricity, and source methane from methane capture projects?
If possible that would seem ideal, however we don't exactly have tons of excess fossil fuel free methane just sitting around waiting to be used, atleast compared to the absolutely massive amount of fertilizer we need to produce to feed farmland. And if you are eliminating the fossil fuel from production, you might as well eliminate the methane component too and produce hydrogen on-site from water. The main problem is…

Funnily enough, leather tanners and pee is where the terms "piss poor" (being so poor that you need to sell your pee to tanners for cash) and "doesn't have a pot to piss in" (can't even afford a thing to hold your pee to bring to tanners) came from.

The administration didn't even bother manufacturing consent this time and yet the media is acting like they did during the Iraq war. Democratic leaders are weakly pretending like they opposed the war but they really stalled the war powers resolution so it would happen before they forced the vote. Now they get to spend the first half of their statements condemning Iran and the second half weakly protesting about proce…
> administration didn't even bother manufacturing consent this time and yet the media is acting like they did Which might suggest holes in Chomsky’s hypotheses. > they really stalled the war powers resolution so it would happen before they forced the vote The war’s timeline was moved back so materiel could be relocated and moved up because of Khamenei’s meeting. Democrats don’t control the Supreme Leader’s calendar.…
Completely agree. My problem is with his use of the entire nation's war fighting system and materials. We should at least have our elected representatives vote, after the Senate deliberates. None of that happened as you note. One guy, one vibe, one nation.

And what percent of diesel emissions are from diesel passenger vehicles? Emissions reduction efforts would be better spent ensuring repairability. The sunk cost emissions of landfills filled with junk created by planned obsolescence is much worse. Diesel pick ups are not practical vehicles. Let's be honest, it's a hobby. It's always going to be niche and cutting down the last 10% is always the hardest. General aviati…
Not sure what your point is, I was talking primarily about Class 8 heavy duty commercial trucks (semi) and other medium duty commercial use. All the stuff that makes up emissions gear is highly recyclable and in fact some of it very desirable which is why people are getting catalytic converters stolen. So I do not worry about it filling up a land fill. I also don't worry about EV batteries filling landfills because a…
Take appliances for example, the government basically mandates that they're energy efficient but the new linear compressors break. Cars got more efficient by tightening tolerances. There's always going to be an engineering tradeoff between reliability and efficiency. I just think the environmentalist types have been laser focused on creating efficient by non durable products that fill landfills.
On another hand, everybody (or at least I want to believe) in the region knew in the back of their mind that the whole situation was a powder keg with a short fuse, and should have done more to diversify energy sources beforehand.

The given origins for these phrases seem to be considered a modern myth: https://grammarphobia.com/blog/2019/07/a-pot-to-piss-in.html https://www.wordorigins.org/big-list-entries/piss-poor-pot-t...
