The wordy article boils down to: the baths were infested by bacteria and worms due to insufficient water cleaning. Interesting, but could be compressed to 2-3 paragraphs without losing any detail.

Thanks for posting though.

I'm curious as to why you chose that particular vehicle. It's an interesting choice for someone on HN. What convinced you that this car was right for you?

The concentration of lithium in seawater is quite low, approximately 0.17 milligrams per liter (mg/L) or 0.17 parts per million (ppm).

To determine how much seawater is needed to obtain 1 gram of lithium, you can set up a proportion:

Given: 1 liter of seawater = 0.17 mg of lithium x liters of seawater = 1,000 mg (1 gram) of lithium

Using cross-multiplication:

x = (1,000 mg * 1 liter) / 0.17 mg x ≈ 5,882.35 liters

Thus, you would need to process approximately 5,882.35 liters (or about 5.88 cubic meters) of seawater to obtain 1 gram of lithium.

In practice, extracting lithium from seawater is more challenging due to its low concentration and the presence of other elements. Techniques have been proposed and researched, but as of my last update in 2021, they were not commercially competitive with other sources of lithium like mineral deposits.

Thanks, didn't notice this discussion.

Does anyone know if there's a method to effectively "subscribe" to news pertaining to topics like this? I'd greatly appreciate being able to keep up with the latest research in certain fields, such as this one.

You seem to really disregard the positions of this author. They seem to have invested substantial efforts in that specific area of research.

To validate the idea the author has, it would be required to train a LLM from zero. If the author is right, you would get similar results to the current generation of LLMs, but with (a lot) less space required for the intermediate layers.

The time to achieve that is still measured in kilo- to mega-dollars, why is it wrong to put that idea in the open to substantially criticize or adopt?

This is rather incredible, both in its simplicity and the fact that I never read about it yet. Thanks for posting.
