What is carbon capture? And how does it work?
While carbon capture is regularly discussed in the media, no one really ever explains what it is.
Below is a quick thread discussing the technology behind traditional carbon capture 👇
Technology is connected to the "tailpipes" of these facilities and is used to remove CO2 from the plant exhaust.
This step is called "sequestration" and is why experts often talks about "carbon capture and sequestration" or "CCS".
Currently, one of the most economic forms of carbon capture is called "amine-based" capture.
An "amine" is a special liquid chemical which selectively grabs on to CO2 molecules.
The exhaust bubbles up through the column, and the amine drips down.
The liquid amine and gas exhaust mix in the column.

The amine with dissolved CO2 is sent into a second column where it is heated.
In the second column, the CO2 pops out of the amine.
Now, we have separated the CO2.

Below is a picture of an amine plant used for CO2 scrubbing.

The CO2 is injected into a well for permanent storage underground, usually a few hundred yards away.

What I've described is called "point source capture" because it captures CO2 from a single plant exhaust
With new advances in technology, CO2 can also be captured directly from the air we breathe

I've recently come across a disinformation around evidence relating to school closures and community transmission that's been platformed prominently. This arises from flawed understanding of the data that underlies this evidence, and the methodologies used in these studies. pic.twitter.com/VM7cVKghgj

The paper does NOT evaluate the effect of school closures. Instead it conflates all ‘educational settings' into a single category, which includes universities.

The paper primarily evaluates data from March and April 2020. The article is not particularly clear about this limitation, but the information can be found in the hefty supplementary material.

The authors applied four different regression methods (some fancier than others) to the same data. The outcomes of the different regression models are correlated (enough to reach statistical significance), but they vary a lot. (heat map on the right below).

The effect of individual interventions is extremely difficult to disentangle as the authors stress themselves. There is a very large number of interventions considered and the model was run on 49 countries and 26 US States (and not >200 countries).

I find it remarkable that a section of society not rejoicing that children very rarely ill with COVID compared to other viruses and much less infectious than adults
— Michael Absoud \U0001f499 (@MAbsoud) February 12, 2021
Instead trying prove the opposite!
Why??
2. @c_drosten has talked about this extensively and @dgurdasani1 and @DrZoeHyde have repeatedly pointed out flaws in the studies which have purported to show this. Now for the other assertion: children are very rarely ill with COVID19.
3. Children seem to suffer less with acute illness, but we have no idea of the long-term impact of infection. We do know #LongCovid affects some children. @LongCovidKids now speaks for 1,500 children struggling with a wide range of long-term symptoms.
4. 1,500 children whose parents found a small campaign group. How many more are out there? We don’t know. ONS data suggests there might be many, but the issue hasn’t been studied sufficiently well or long enough for a definitive answer.
5. Some people have talked about #COVID19 being this generation’s Polio. According to US CDC, Polio resulted in inapparent infection in more than 99% of people. Severe disease occurred in a tiny fraction of those infected. Source:
I'm going to answer the question so many people have been asking this week:
WHAT IS PROJECT X???
Here's the definitive thread to tell you - and show you -precisely what Project X is
Grab a drink, sit down with me and let's #TalkLiberation

"Project X" is actually called "PanQuake".
Pan means "all". Quake is the huge effect our voices can have when our communications are uncensored and when we have access to brand new functionality that *enhances* our social reach, rather than diminishes it
Here's our logo:

SPOILER ALERT: Much of the content below this point is from my personal slides & speech notes from today's launch event. That stream got totally ruined by (big) tech problems, but I'm happy to report everything is turning out wonderfully
Not one single team member or guest left. We are all still here, smiling not crying, as we record this event and will get it out to you all very soon :)

I'm so proud of everyone, what an amazing crewhttps://t.co/RmE0BicIXF
Here are some of our most high profile & dedicated public advocates for PanQuake - many of whom were scheduled to appear at our launch. All of whom stuck around for hours, to do a prerecord of the event, which is being edited, processed & uploaded for you as I write this.
