What's the cheapest Carbon Capture system we can imagine - $100 per tonne? Most are running at about $500/tonne right now.

At just $15/tonne of Carbon Tax, we halve CO2 output, mainly by destroying the economics of coal:

https://www.pgpf.org/budget-basics/what-is-a-carbon-tax-how-...

All the effort and funding currently spent on carbon capture should instead go towards lobbying for carbon taxes. The impact will be significantly greater.

The best use of Carbon Capture technology would be in building ventilation systems. If we can capture and exhaust CO2 from inside air, we can reduce ventilation requirements, and potentially reach lower-than-atmospheric CO2 levels (which could have extraordinary benefits for cognition and sleep quality).

I’m reminded of the (fantastic) documentary about a building I once lived in: Aragon Tower in Surrey Quays [1].

Since it was built in the 1960s, it was one of the tallest council estate buildings in all of London, but ~twenty years ago private developers bought it out and converted it into “luxury” flats. At the base of these flats however, is the notorious Pepys council estate, of which Aragon Tower was once a part of.

The documentary aims to shine a light on the disparity between the varnished lives of glossy marketeers and new residents of those in the “upgraded” tower, with the folks forcibly removed, and those in the Pepys estate with exceedingly hard lives.

Highly recommend.

650M$ in funding and they will remove emissions from about 10 000 cars! You could just spend 32 500$ per each car to replace it with an EV and the second 32 500 on renewable energy and storage.
We would need 100 000 of these plants to get back to equilibrium.

It was only recently that I learned GIT doesn't store deltas as it's core functionality, which is how I had presumed it works. It's just saving snapshots, and making up the deltas in retrospect, for purposes of merging, etc.

In using it, you're always confronted with deltas, so it seemed that was how it worked. The command structure didn't correspond at all, and was thus very confusing.

Git is really a contents addressable archive disguised as a version tracking system.

> TFA makes it pretty clear that the energy source is geothermal.

Is it more likely that when this plant switches on, other people will just make do with that much less electricity, or that when this plant switches on, electricity production will go up?
That's great to hear!

As for going deeper, I don't think there's a way for someone to go deep enough without actually putting them on the job :)
Thanks for the info, I had no idea
Yes, reverse the sign. Carbon emissions are not tracked in our existing accounting systems. Integrating carbon tracking and emissions into our society is inevitable, but it's only going to get more expensive the longer we wait.
If it means decoupling energy production from further destruction of our planet? Sure, why not? Even assuming that "the technology for nuclear power is the same as the technology for nuclear weapons" (which is patently and blatantly false), MAD seems to have prevented global nuclear annihilation for a good 50 years or so, and I don't see that changing any time soon.

I recall it being printer-specific also. Dell laser would do it, Brother (?) wouldn't. There was even an app (Booklet Maker?) for n-up challenged printers.

I imagine it's a printer-implemented feature, like duplex, with a very high-level option flag. A Postscript printer with a full-page RIP buffer could probably do it pretty easily if it wasn't extremely resource constrained. A RIP that did banding internally, re-compositing the PS source several times (are there [still] such things?) would have a hard time. A bitmapped printer (the cheap all-in-ones) would need to hold the entire page in memory on the Mac. Back in the day (way, way back), at least, drivers would process in bands, and the apps were required to re-draw the relevant parts of the page for each band. There wasn't any provision in the API to work on multiple pages at once. I don't know if application-level banding is still a thing, but could see echoes of incompatibility remaining.

Edit: n-up implemented in the OS can be tricky for Postscript printers. It requires nesting pages inside pages. Ill-mannered, but legal, Postscript can cause issues. It might be better with newer versions of PS, but the OS would still need to support older printers with old versions.
From the abstract of NBER paper I mentioned [1]:

> Each year Americans spend over two billion hours and $30 billion preparing individual tax returns, and these filing costs are regressive. To lower and redistribute the filing burden, some commentators have proposed having the IRS pre-populate tax returns for individuals. We evaluate this hypothetical policy using a large, nationally representative sample of returns filed for the tax year 2019. Our baseline results indicate that between 62 and 73 million returns (41 to 48 percent of all returns) could be accurately pre-populated using only current-year information returns and the prior-year return. Accuracy rates decline with income and are higher for taxpayers who have fewer dependents or are unmarried. We also examine 2019 non-filers, finding that pre- populated returns tentatively indicate $9.0 billion in refunds due to 12 million (22 percent) of them.

When trying it out to see if there is any automated sentiment analysis, I noticed that my line of "a" just stretches endlessly out and breaks the text box. Anyways, does HN want to offer feedback on the first game involving explaining an issue to Mr. Smith about his ACME engine part? I was so concise that I couldn't submit without adding some screaming noises to get my word count up.

(also, this was valid, so no - there is no sentiment analysis or anything similar to see if you still got the message across)

> At just $15/tonne of Carbon Tax, we halve CO2 output, mainly by destroying the economics of coal

Here is page 122 of NextEra’s investor deck. They are closing all coal plants by 2028 as they are no longer profitable to run. Even without a carbon adder per MWh, coal is dead (“near firm” solar and wind are renewables with battery backing to make them dispatchable when called on by the grid operator). Even existing combined cycle natural gas is under pressure! And their note: “We expect further technology improvements and cost declines will extend the competitiveness of onshore renewables and storage.”

https://cleantechnica.com/files/2022/06/lcoe-small.jpg?mrf-s...

Japan is opting out of financing coal plants further in Indonesia and Bangladesh, cancelling ~3GW worth of coal plant projects.

https://news.mongabay.com/2022/06/planned-coal-plants-fizzle...

So we’re seeing some progress in avoiding electrical thermal emissions, which is the cheapest emissions offset.

(Oahu, Hawaii’s last coal fired plant turns down in September after the Tesla Megapacks replacing their frequency response capability are installed, another 200MW of coal taken offline)
But don't worry, you can choose what to have taken out of your body but you will have no say over what goes into it in some countries...
Indoor CO2 scrubbers (even just to separate CO2 from inside air and exhaust it outside) would be a great technology right now, since it would allow us to reduce ventilation requirements and thus save on heating/cooling costs.
I haven't ditched my phone, but ever since I started using a Macbook, I have been only using my iPhone maybe 10 minutes a day (mostly in the bathroom). I read/write SMS, browse photos, toggle hotspot etc. from the Macbook.

I am in fact paranoid. Clinical. Diagnosed. The works.

But I've also gotten out of shitty situations with that paranoia. Another way to describe it is "pessimistic creativity". But I am also risk-seeking, so the whole thing is being totally paranoid strictly in the situations that are actually dangerous, and apart from that, like if there's a threat go to the bunker and stay there as long as it takes without compromises and no regard for peer pressure, apart from that...roam downtown Santiago at 3 in the morning because it's no big deal. I'm no fraidy cat.

Fear what you have to fear, forget about everything else.
I assumed that the gap between the cost to do the bare minimum and the cost to do some elaborate was smaller at the time. If you're already laying each brick by hand, it seems like the incremental cost to work a pattern into the bricks would be small compared to modern (bland) poured-concrete buildings, where we lay a whole floor in one go. Likewise in other trades.

We invented machines to build large amounts of simple things cheaply, so we designed simpler things.
This seems beyond misleading it doesn't even have a method to enter most of the now illegal methods to lower your tax bill.

Tax straddles were only banned in 1977 before that you should have easily been able to more then halve your tax bill with futures.
The opportunity cost of not investing is in a different ballpark from spending that money on machines and electricity.

Yeah but the oil wells were built as part of an energy providing supply chain - it has actual use. This carbon is going to be injected into the ground, so there’s no economic incentive to building and operating these plants. If the subsidies are enough, and therefore the incentive great enough, then they will be built - but the incentive for reversing climate change has been a difficult area to break through.
That’s the easy part. It doesn’t tell you how local and remote interact and how the working tree, index and repository interact, and how to handle the issues you can run into with merging, rebasing, etc.
What finally pushed me to use an IDE was the code inspection tools running in the background, and lighting up my likely bugs and style mistakes. So it's actually reacting to my code and doing something, rather than just flooding me with information.

For now, Spyder (for Python) is just right. VSCode is too much, and I haven't figured out how to turn off the features that I don't care about.

Yes, the Kolmolgorov complexity of a string X is the minimum length of a program/string that when fed into an efficient universal computer will yield back the string X. The Kolmolgorov complexity of a string is also undecideable - it's essentially equivalent to the halting problem.

The analogy isn't perfect, but the point is clear. Refining and developing imperfect Co2 extraction technology today can pay massive dividends in the future.
More like if you take some cellophane and crinkle it up. The thicker parts block more light than the thinner parts, so if you look at the shadows, you'll see structures that aren't representative of the shape of the material.

That reminds me of the when the openWRT and other open source guys were complaining that the home gateways of the time did not have a big enough CPU to max out the uplink (10-100mbps at the time), and instead built in hardware accelerators. What they did not know was that the hw accelerator was merely an even smaller CPU running a proprietary network stack.
I didn't point that out: I originate from a country in which I used to get a postcard summarizing what they thought I owed with a "Yes, I agree" checkbox and a field to sign. You could always file an extensive return if desired, but unless you had complicated (notably international) transactions, the return was basically accurate.

This only works because there's a high level of trust in the government and low corruption, and having detailed tracking isn't (very) controversial. The US is almost the exact opposite on every metric so it wouldn't work for it.

The original "imaginary property" is land. There are people who make the same argument against the legal fiction of "owning" a piece of the ground.

I'm really worried we have no idea what we're doing, and will find out down the road things like this only made things worse, or caused other unforeseen problems.

I do not subscribe to the philosophy that "doing something is better than nothing", particularly when we likely don't fully understand what it is we're doing or actually trying to achieve. Doing the wrong thing can be, and often is, worse than doing nothing.

> Orca can capture about 4,000 tons of carbon per year (for scale, that’s equal to the annual emissions of 790 cars).

That's some hand-wavy numbers there. 790 of what type of car? 1970 muscle car without a catalytic converter and modern fuel injection system? Or a 2022 Prius? One outputs a huge amount of CO2 and other gases, and the other hardly any at all.

Car emissions are really good on average. As technology progresses, it might be fathomable that 7,900 cars, or eventually 79,000 cars produce the same amount of emissions as today. This "metric" sounds impressive, but it's useless.

> DAC’s energy usage, particularly when it’s considered in conjunction with the (relatively minuscule) amount of CO2 it’s capturing, is its biggest drawback. Sourcing the energy from renewable sources helps, but it’s still not unlimited nor free.

So why are we not just using the geothermal energy powering this thing to charge electric vehicles or power homes?

> Meanwhile, global emissions topped 36 billion tons last year. 36,000 tons (the quantity of CO2 that will be captured by the Mammoth facility) is a negligible fraction of that total. Is it even worth the energy usage, construction and maintenance costs, and frankly, the effort? Or would the geothermally-generated electricity go to better use powering electric cars?

Ah, they even mention this in the article. Of course the CEO hand waves this away...

I'm not convinced this is the future - seems more like a get rich quick scheme if anything. Sort of like those companies you can pay to "offload" your emission burden and supposedly they plant trees or something and you get to claim your carbon neutral. Scams... all of them.

Most cryptocurrency promotors claim that they have this brilliant team and a great roadmap and in the future all the activity they're going to promote is what will make the token worth something, etc. Which is actually what does make them a security.

The claim in the article is that Bitcoin is mostly not like that. There's a protocol and a bunch of users, but there's no one who's leading the enterprise and causing the value to do something. Not sure I buy that claim, but it's not totally crazy.

There will be no one solution. The population will shrink, we'll switch to electric cars, we'll eat less beef, we'll replant some forests, we'll capture some carbon from the air, we'll grow some algae in tanks, we'll scoop up the plastic in the sea and bury it.

Then hopefully, with a little wishful thinking, future generations appreciate our environment a little more.

Hopefully nobody will go to war, or starve, or go bankrupt in the process.
