I get where you’re coming from, skepticism is healthy and, honestly, necessary when it comes to big promises about tech solutions for climate change. But I think it’s worth taking a second look at carbon capture technology. It’s not about being gullible; it’s about exploring all our options to tackle a massive issue. Sure, it’s had its share of ups and downs, and, yes, it requires substantial investment and development to be viable on a large scale. However, it’s far from a scam.
I worked as a researcher in advanced materials for carbon capture, an alternative to the traditional carbon capture that uses amines for “capturing carbon” (a better term would be “carbon separation and storage”, BTW). The TRL (Technology Readiness Level) of amine-based carbon separation is 7, meaning that it has been implemented in large-scale facilities in operating conditions (specifically, at the Petra Nova Power Plant, which unfortunately closed down due to the low oil price during COVID). The rest of the carbon separation technologies (adsorption media, membrane, cryogenics, etc.) have not yet passed TRL 4 or 5, but they are expected to continue to find niche uses. Bottom line is that all of the methods WORK technically, but decrease power generation efficiency, so they may or may not work economically. Regulations and quotas could lift this obstacle.
Dismissing it outright as a ‘scam’ might be overlooking the potential benefits it offers in reducing CO2 emissions. It’s definitely not the sole solution, and we need a broad strategy that includes renewable energy, energy efficiency, and conservation. In fact, the main obstacle that “carbon capture” technologies face is in terms of public opinion, with companies branding the technology as a “silver bullet” that magically makes all previous and present emissions go away, sometimes without even investing in the research and development necessary to make it work, like ExxonMobil did. Or they imply that since they are doing “carbon capture,” the other strategies are obsolete, which is definitely not the case.
However, writing off carbon capture entirely could mean missing out on a valuable tool in our fight against climate change. Let’s keep the conversation open and critically assess all possible solutions, including this one. What do you think?"
In my experience, this is because they conduct yearly x-ray examinations to detect tuberculosis and other lung diseases. Shirts and bras interfere with the image, so they ask students to bring a plain shirt to wear during the examination. However, if there’s no other option, they may ask them to do the examination bare-chested. In my case, there was gender separation (not only in location but also in the time frame), but I can’t say the same for all schools or age groups. Japanese schools are known for having students change into sports clothing in the classroom without gender separation up to 3rd or 4th grade, so I wouldn’t be surprised if there are schools that don’t separate genders for medical examinations.
