Within one year, from April 2023 to Jan 2024, market prices per kWh dropped 50%, from about $200/kWh to $95/kWh. And this is no fluke powered by one-time events. A lot of progress in the last few years was indeed technological and came not from new chemistry. The Cell-to-Pack and Cell-to-Blade processes, which allow very large but still stable cells made the LFP cell viable for automotive application and Sodium cells at least for stationary use. Doting the LFP with Maganese, creating LMFP cell types can add another 20% of capacity within the same technology. Anodefree cells (where the anode will form itself with the first charge) will allow for even cheaper production. Organic cathodes might boost the capacity of sodium cells up to 600 Wh per kg, but are currently very expensive compared to iron phosphate - but if the organic compounds are cheaper to made, they will become competitive.
You won't find many of the new ideas in your everyday cell. But that's not because the ideas are not viable. It's because the current cell types are progressing themselves so fast, that they are still the most marketable option. But whenever the development slows down too much on them, the other options are ready to shine.
Your body contains about a kilogram of phosphorus. Your bones, teeth, and DNA are made of phosphorus.
And still, White Phosphorus is deadly in doses of less than 1 ppm. Enumerating elements is completely meaningless when talking about toxicity. What matters is the substance which contains the elements. And two chemically closely related substances can be harmless and absolutely toxic. Botulinum toxin, often called Botox for short, is deadly in doses above 2 ppt (or about 150 nanograms for a grown adult), and all it contains are the very same amino acids, which make up about 15% of your body weight.
Copper is necessary for human life.
Same silly argument.
Luckily, posphorus is quite reactive (that's why it was used as an agent in matchsticks), oxidizes fast, and will form phosphoric acid when exposed to air, which indeed is not toxic. It is similar for copper, albeit some copper oxides are themselves toxic.
Germany, which is known for being well organized, had a similar catastrophic flooding in 2021 (184 dead) in the Ahr Valley. Also here, the Weather Service had warned about heavy rainfall and possible catastrophic flooding, but it did not register with the people responsible for civil protection.
That's a real problem with once-in-a-century events. People just can't imagine the possible damage, and are completely unprepared or even consider preparations as wasteful and an obstacle to business, development or personal freedom.
And LIGO can't test the small Black Holes hypothesis. It measures gravitational waves in the wrong frequency band. The lowest mass it can detect is about the size of a neutron star binary (~ 3 solar masses). Advanced LIGO will be able to detect masses down to a single neutron star (1.4 solar masses), still too large for the hypothetic small primordial Black Holes.
The problem is: Where to?
We have no obvious path, and the ones proposed so far are even more elusive. Physicists would love to move on, and the ones leading a promising new way will be hailed as the Newtons and Einsteins of the 21st century. Currently, we are in the process to mark out all possible places to look, and we are crossing out the squares we have searched so far. Each square cleared is a success, because it narrows down the places to look even further.
Biology is the only science in which multiplication means the same thing as division.
