The basic question is what is easier/profitable: mining lithium or processing existing used lithium batteries.

The most important nutrients are e.g. NH3, NH4OH, NH4NO3.. Do you see any sign of CO2 in them? No.. Fast growth requires artificial nutrients i.e. made by the chemical industry. CO2 is taken up by green parts of plants i.e. tree leaves.. Greenhouses are solid constructs which can have much higher concentration of CO2 than ordinary air, but they must be closed, so CO2 does not escape. Which limits height of plants by height of the construction. You don't seem to understand what soil is.... It is the remains of dead plants and other organisms, decomposed in the oven thousands and millions of years. Pumping CO2 into the soil.. ? Again, CO2 is taken up by green parts of plants i.e. tree leaves.. Hydroponics goes reverse route - do not use soil at all.. https://en.wikipedia.org/wiki/Hydroponics

Use the right kind of tool for the right kind of job..

Plants need: CO2, H2O, NH3 and/or NH4OH and/or NH4NO3 and other nutrients with various other elements. Higher availability of CO2 will be of course welcome, but soon other bottlenecks will be reached in other areas. i.e. lack of light (artificial or from the Sun), lack of nitrogen-rich nutrients.

An audio speaker is a mixture of a magnet and an electromagnet attached to a diaphragm (or reverse). When current flows through the electromagnet, it begins to tremble and causes air molecules to move..

I guess, he meant that they slowed down from their initial relativistic velocity to the frame of reference of the surrounding galaxy, so they are barely moving, only just as much as the entire galaxy in which they remain.

From time to time, rarely, the annihilation of an electron with a positron leads to the production of a neutrino and antineutrino pair. https://www.google.com/search?q=electron+positron+neutrino+antineutrino (in addition to their normal formation by beta plus and beta minus decay)

In the thread https://stackoverflow.com/questions/12967541/how-to-avoid-staleelementreferenceexception-in-selenium "This can happen if a DOM operation happening on the page is temporarily causing the element to be inaccessible. To allow for those cases, you can try to access the element several times in a loop before finally throwing an exception." "Generally this is due to the DOM being updated and you trying to access an updated/new element -- but the DOM's refreshed so it's an invalid reference you have.."

Admirable. Do you have all the walls properly covered with Styrofoam? It would help in decreasing energy usage. Why not to produce more for your friends and neighbors who don't have installation yet? How about making your own heated greenhouse for vegetable production?

In a limitless environment i.e. your own building with enough money, just for heating, you should consider taking solar collectors. They heat water or other fluid in pipes going around house. I would have TV, computers, 3D printers, refrigerator, washing machine, and water boiler (water for bath) plugged to them all day long.. Change habits, such as bathing, washing clothes during the day rather than in the evening.

It is not always the case: https://community.letsencrypt.org/t/lets-encrypt-not-automatically-renewing-certificates/70678 https://support.cloudways.com/en/articles/5128853-fix-issue-of-let-s-encrypt-ssl-not-renewing-automatically

You can/should 1) remind owner about upcoming expiration date in advance 2) ask owner of the server to extend admin list to a few people who will be able to do it.. Set an alert in cronjobs.. The SSL certificate will expire in 43 days.

Because you did not do what I asked to do years ago - there must be created alarm for mods starting a couple days before the next 16 October 2023,2024,2025+.... There will be probably second problem with expiration of SSL certificate... Check when it has expiration date. OK. I will do it for you... https://www.sslshopper.com/ssl-checker.html#hostname=www.scienceforums.net "The certificate will expire in 43 days." This shows a severe problem. There should a group of people who have readily access to the server and will be able to pay bills for server, domain and certificate, and edit the settings. If there is one admin who has the all things on an encrypted and password-protected machine, his or her disappearance for whatever reason will be the end, as nobody will be able to pay bills in advance prior expiration date...

Pro V.P. people the main motto is: "Après moi, le déluge".. ("After me, the flood")

Hm?

@iNow OP specified, said "both cities".. see above.. Undoubtedly.

Neither Seoul nor New York grounds are used by farmers.. so, what actually want do you to compare?

In long term - obviously.. In long term - obviously..

People don't want to be here because they are in pain. Physical pain, metaphysical pain, existential pain.. Understandable. Some/most sources of pain can be cured/repaired. "Success" = "existence of human beings one day longer"....

Eternal life or rather eternal existence.. ? ..in the midst of artificial intelligence that will ask the question "the meaning of life?" or other mortal beings asking questions in a scientific forum like "What does success mean?"... ...your spectrum is too short...

It depends on the temperature of the washing machine. There are 90 C, 60 C, 45 C, 30 C.. Bacteria can't survive excessive heat. Bacteria cannot thrive in the absence of food.

Pillow #1 != pillow #2.. They differ.. You have to have information about them to decide. I wash my pillows entirely in the washing machine. They are designed for that. They are allowed to be washed in the washing machine. There is a washing procedure listed on their label, etc. etc. So, basically, read the label to find out.. I try to wash the pillows every few months. One every month. One every two months. If you don't think they are "fresh," you should wash them. BTW, pillows are cheap. 10 euros for 60x50 cm one.. The key is to use 1600 RPM during spinning in the washing machine. The more the better. After that, or x2, pillow or quilt, should be almost out of water and almost dry. I washed my pillows and quilt maybe 5 times in 2022, and will do more this year..

Not really. It is connected to giving/sustaining life. Just because if you don't drink, you die. Nonsense. In Christianity it is just a symbol of reborn after you wash you're clean i.e. flushed all previous "sins" (even if you did not have any like newborn).. Nonsense. Primitive people have primitive superstitions. Nonsense. The creator of the Universe likes quantum physics, if you did not notice yet.. Nonsense. It can be used to create fusion reactor, or nuclear weapon.. For primitive people, indeed, something "magical".. Nonsense.. ps. BTW, you "forgot" to mention Ganges... "The Ganges is the most sacred river to Hindus. It is worshipped as the goddess Ganga in Hinduism. The Ganges is threatened by severe pollution." https://www.google.com/search?q=ganges+holy+river

This is a clever question in physics. Do you know the equation of the distance traveled by an object falling at a given acceleration? Reverse it to have time as result and distance and acceleration as parameters. The distance is known. The acceleration is known. Only the time is unknown. Have two such equations, but with different accelerations of 10 m/s^2 and 9.8 m/s^2, and divide them together and multiply by 100% to get the percentage difference, and subtract to have the absolute time difference in seconds.

Remembering how Muslims around the world reacted to the collapse of the World Trade Center, this will be a very quick test.. Astonishingly, even those who are regularly paid by the U.S. and their countries are completely dependent on foreign aid.
