Unless everything collapses, which is still a real possibility if we can't get climate change under control or nukes begin flying, idk if there will ever be another Era of complacency given how things are going. It's wild too, because in ancient history literally most of it was complacency, and now there's groundbreaking tech almost every week

Yeah, I've found myself having to educate people who speak of the Holocaust in reference to the extermination of Jews with the somber reverence it deserves, but then go and spout homophobic bullshit immediately afterward.

I even had to remind a practicing Orthodox Jew that they weren't the only ones who were systematically targeted for genocide, and that I'm one of those people too. I knew it was a bold move, but she took the point well and I didn't press that point further. I wasn't intending to make a wound, but I needed her to know that I was yielding no ground in the argument that we deserve equal human rights in the pursuit of our own lives, liberties, and happiness.

He never said anything about doing nothing, just that it's a lot for a underwater bike garage...that seems very impractical. You can easily store bikes at home, and it allows instant access to the bike.

You can also check his edit and he clarifies his issue with it. You're just jumping to some anti climate change argument that wasnt made.

It has become tiring to see/read comments on posts like this. It's nearly always by people with little to no knowledge of chemistry and chemical engineering and/or the reality of the green energy economy.

One of the top comments is usually something in the realm of "plant trees, use solar/wind, no need for carbon, etc."

No, you can't just plant tress and avoid technologies like the one proposed in the article. Find a way to electrify everything and produce all the chemicals we need without using carbon. Then we can talk about eliminating carbon from our lives.

The idea presented in the article is actually not really new. They just went a bit dramatic with their advertisement. The group of Heldebrandt themselves (the ones discussed in the OP) have published many articles on this topic, and others have too. I am yet to fully read the actual journal article they published, but the likely cause of this popular science article is higher efficiency in converting the captured CO2 to methanol.

If their idea goes through more testing at increasing scales, then it could be implemented in the industry. Right now the commercial route to produce blue (fossil hydrogen + natural gas + carbon capture) or green (renewable hydrogen + carbon capture) methanol from CO2 is an indirect route of first converting CO2 to something called a synthesis gas and then converting the synthesis gas to methanol. If the intermediate step can be eliminated, it would lead to better energy efficiency and economics.
