This article makes no mention of the power required for a process like this. A few days ago there was a post describing the older seawater method which stated that to remove as much carbon from the ocean as we are putting in would require ~70% of current global electricity production.

Unless the improvements made here are really significant, I don't see how this actually solves anything until we have moved to truly clean energy production.


The linked paper says this uses 122 kJ/mol. I translated that into more familiar units, and it came out to 770 kWh per metric ton CO2.

If you were dumb enough to power it with coal then you'd have net emissions, but put it someplace sunny, power it with solar at 2 cents/kWh and you're paying just $15.40 in energy cost per ton of CO2 absorption. One gallon of gasoline produces 20 pounds of CO2, and there are 2204 pounds in a metric ton, so you could pay for this by adding a surcharge of just 7 cents/gallon.

Of course that's just energy cost, there's also capital cost, and I don't have an estimate for that. But it's not obviously unworkable. Reducing emissions is usually better but I could see this being pretty helpful for cleaning up things that are hard to decarbonize, and once we hit net zero we'll need tech like this already scaling to bring CO2 back down.


I used to do this a lot and still catch myself doing it sometimes.

Personally I think it comes from not being exposed to a lot of music growing up (my mom is hard of hearing), and just assuming that almost all songs were 2-3 minutes. I'd say that the thought process behind it also has something to do with longer songs requiring more time or dedication to learn all the lyrics, so it feels more special when you know and really enjoy a longer song.


My high school had a whole push for teachers to try flipped classes. I found them to be really nice, skipping through the video when they're repeating something I already got, or re-watching something if it didn't make sense. Despite this, general sentiment of my school seemed to be that they were terrible. I heard complaints such as not being able to ask questions immediately, or feeling disengaged compared to being taught live.

All and all I wish my college did them, I struggle to sit through lectures.

I had the same thought.


Seems like you're looking for Montessori schooling. I was actually fortunate enough to attend one for ages 3-5. Although I don't have many memories from then specifically, I do remember repeated bordem when I stopped going and was moved to public school. I always wanted to do more hands on activities as I had before, but the closest it ever got was art.

Another note of interest, my senior class at high school consisted of 4 people whom I attended Montessori with, of those four, three took IB classes and participated in clubs / extracurriculars above the average rate for my school. I can't help but wonder if even just those few years at a young age made a lasting impact.


I'd expect it to be the parents choices, same for whether boredom is tolerated or encouraged at home.


I'd partially blame this one on the Steam app too. If it is able to receive the message and give you a notification, it should also let you see that message in-app without internet.

Discord is the same way and it drives me mad, especially considering how fussy it can be about connecting. Snapchat on the other hand handles it right. If I get a notification (for an actual chat at least), I am able to open it anytime later regardless of whether or not my phone is still connected.


Swype is absolutely fantastic when it works right. I also agree that it would greatly benefit from having a better algorithm behind it.

Given how accurate search suggestion algorithms are becoming, I find it surprising that keyboard suggestions are as bad as they are. If swype could have the same predictive abilities as search engines it would be a major boost in speed and comfort.


I was with my previous girlfriend for ~5 years, and have basically been using Gboard the entire time. We communicated via various messaging services literally every single day. If I was to try swipe-type her name right now, there is a 50% chance that it will suggest a different but similar name that I think I have literally never accepted as a suggestion.

I was expecting this feature when I got my first Android phone over a decade ago, and I am still waiting for it. Is there some engineering step that I'm missing? Model my typing history and use that for prediction weightings. Is this unfeasible on my phone hardware?


Swype lets you long-press a suggestion and choose to never suggest that again.


Google's Android keyboard (GBoard) has swiping capability. Still not great, I think the problem is the keyboard isn't able to go back and correct previously typed words based on subsequent contextual information.


I think that Sudoku could be categorized with those.
