Australia must continue to mine Uranium because it is needed to produce fusion fuel. Human thermonuclear fusion is a D+T reaction. It is an atypical reaction in the Universe/stars. But it gives much more energy than the typical H+H path. Uranium is needed to create D and/or T. or an alternative path. It is not possible to produce tritium in advance, since its half-life is 12.32 years. If one wants to have fusion reactors, one must also have traditional nuclear reactors and Uranium mines.

No. We should not give up on the fusion. ps. You should give up from posting stupid posts and stupids threads instead..

...then stop pretending to have wisdom you don't have..

The earth is not a living being, so it has no problems. These problems are created by humans to other humans, living now or to future generations. I disagree. Aluminium has pretty good recycling rate.. https://www.google.com/search?q=aluminium+recycling+rate "The global Recycling Efficiency Rate (RER) of aluminium is currently 76%. The RER defines how efficiently aluminium is recycled throughout the value chain." https://www.google.com/search?q=lead+recycling+rate "A Sustainability Star: Lead Batteries Maintain Impressive 99% Recycling Rate. As we celebrate America Recycles Day 2023 on November 15, it's important to highlight the remarkable sustainability achievements of the lead battery industry." Charts with various elements: https://www.google.com/search?q=metal+recycling+rate e.g. Lead used in ammunition, etc. is the margin of its use. It is highlighted in yellow on this chart: Of course, the higher the recycling rate, the better. But it is still impossible to achieve 100.0%. One can only try.

There are different types of motors. Induction motor is just one of types. The difference between the two types can, of course, be found on Wikipedia: https://en.wikipedia.org/wiki/Induction_motor https://en.wikipedia.org/wiki/Permanent_magnet_motor Look at Tesla's design in the photo. There is no permanent magnet. We can only see the windings on both the stator and rotor.

Have you heard of influencers on YouTube (or other social media)? This is the "dream job" of most of today's teenagers. I like this machine. Nice IT/embedded programming job.. There is even a movie about it, for children (at a time): https://www.imdb.com/title/tt0910970/ ..but all the land would be bought by the rich.. jobless.. cash-less proletariat cannot afford to buy land..

What about the cats?

..you won't even notice.. Wow. These days they would never do that...

Science can't do anything. It is not an entity.. Scientists can do something, but they only do what their budget allows them to do. They have to ask for even bizarrely small amounts of money to do something, calling it grants. There is an international consortium of fossil fuel supporters backed by army of lobbyists paid by oil and gas companies to destroy humankind / keep their incomes remain intact / as high as possible. People are known for not working for free.. except for volunteers.. What future?

If the quality of food is better now than in the past, why you have obesity disease in the US now... ?

The mortality rate of dictators.. Nice and naive. But if you were really in Russia and read and watched their propaganda, you would know that they are already pushing that it is not a war with Ukraine (what war?! They don't even use that word to the level where people go to jail if someone uses it!), but a NATO attack on Russia.. https://www.themoscowtimes.com/2022/02/26/russia-bans-media-outlets-from-using-words-war-invasion-a76605 Instead, it is called "liberation" and words of similar meaning.. According to the Internet, only 5% of Russia's population can understand what we are talking about. Which makes reaching them quite difficult. https://www.google.com/search?q=how+many+russian+speak+english https://en.wikipedia.org/wiki/List_of_countries_by_English-speaking_population 7.5 million out of 145 million.

The easiest way to get the best score for this project is to use a 3D printer to make air gaps and connections between different layers. Make a project, print, measure the time it's cool. Make the 2nd project, print, measure the time it is cool. Make the 3rd project, print, measure the time it is cool. etc. Pick up the best project to show to teachers. Experiment with different filaments such as PLA, ABS, ASA, PETG, TPU, etc. and different 3D printing techniques. Create a precise spreadsheet to show the results.

Science is like Lego. One piece rests on top of another piece in the right place. When you start discarding something that's really on the bottom, nothing fits on top anymore. Funnily enough, these people ("flat-Earthers") use the Internet and cell phones, which are based on the top few percent.. Flat-earthers cannot live in either Japan, the US or Hawaii. Simply pinging Japan from the U.S. or Hawaii, or vice versa, yields something that completely does not fit their theory. The latency of pings is correlated with the distance the data has to travel in both directions. Such delay is used to triangulate a person, vehicle, etc. So, when you know that Japan has a small ping to Korea, and Korea has a small ping to China, and China has a small ping to India, and India has a small ping to Pakistan, then to Saudi Arabia, Israel, then to Turkey, and then to Europe, you can indirectly measure distances by simply measuring the ping latency from thousands of connections. On a flat Earth, is Japan close to the US? In spherical Earth, data can go through the Pacific ocean, or through satellites, or through entire Asia (which is easy to detect as it is longer distance to the West US).. What flat-earthers have instead? Tokyo-Los Angeles is 8814 km in "straight" line https://www.google.com/search?client=firefox-b-e&q=tokyo+los+angeles+distance while to Madrid there is 9356 km https://www.google.com/search?client=firefox-b-e&q=madrid+los+angeles+distance (plus all the rest through Europe-Middle East-Asia).

On a flat Earth, there would be no day and night cycles and no time zones with different time according to altitude and longitude, nor would there be different seasons.. There would be no polar night and polar day, and no aurora borealis. The poles only make sense on spherical objects anyway. On a flat Earth, distance from lat1,long1 to lat2,long1 would be the same as from lat1,long2 to lat2,long2 and making a perfect rectangle or eventually square.

With ChatGPT v3.5, you can ask the same question in two different ways or in two different languages and get completely different answers.. The result is completely unreliable and even dangerous if one is not aware of how it works, and believes everything without any doubt (like the typical people using it)..

For an atheist, none. The atheist lives in the here and now and does not ask transcendental questions.,

Obviously. If you are omniscient, or the creator of the Universe.

When a skyscraper is built, in some projects, mostly in developed countries, nets are installed every few floors to catch falling builders (Building Safety Regulations etc).. Once construction is complete, the nets are removed. Nowadays, windows in skyscrapers are often designed in such a way that they cannot be opened or broken, to prevent people from committing suicide by breaking them and jumping out. If someone wants to commit suicide, they will find a way around anyway..

..as almost every war shows, human life is almost worthless to politicians..

I have an option for it in the Firefox settings.. about:preferences tab "Open links in tabs instead of new windows"

If it is several LEDs in one bulb, you can see which one has failed, as they are often dark/black upon close inspection.

..price.. ? ..quality.. ?

The oxidation layer acts as an insulator, increasing energy consumption. So it is better not to have it than to have it.

I would start by checking whether the spotlights are connected in parallel or in series. If one is flashing and they are in parallel, it is most likely a defective or defective-to-be spotlight or the wires going to it, otherwise all spotlights would flash, isn't? If you have (doubtful) a lab power supply where you can regulate the voltage and maximum current and observe what is really being drawn, this would be much easier. It is an essential device for electronics engineers. The cheapest brand new Chinese I can find here is for $60. Just plug a spotlight into it and start at 0A and go from there. You would see if there is flashing or not. You can replace places of spotlight which flashes with the one which is not and vice versa, to see if there is a change. Is there any important information missing in the OP? Did you use halogen bulbs and then replaced them by LEDs? Otherwise the above statement makes no sense.. LEDs should be powered from designed for them switched-mode power supply and halogens should be powered from designed for them power supply. Some LEDs require constant current power supply. https://www.google.com/search?q=led+constant+current+power+supply You dim LEDs by PWM, Pulse-Width-Modulation. https://en.wikipedia.org/wiki/Pulse-width_modulation https://www.google.com/search?q=pulse+width+modulation+led+brightness+control (which is a different technique from voltage or current regulation) ..or maybe there is an oxidizing layer between the socket and the LED bulb.. Try an acid, such as acetic acid, to remove the oxidation layer, then clean with isopropanol (IPA).

This is the most reliable way to prevent unauthorized access to files you do not want to share with others. I already said - it depends on the operating system and the file system used. Windows OS has functions SetFileTime. Read the docs. https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-setfiletime and GetFileTime https://learn.microsoft.com/en-us/windows/win32/api/fileapi/nf-fileapi-getfiletime From the user's perspective, RMB on the file and use Properties, and you will have there the timestamps of creation time, last write and last access. "not able to be trusted or believed" https://dictionary.cambridge.org/uk/dictionary/english/unreliable i.e., it can be easily faked. If someone connects your disk to Linux, you will have nothing.. i.e. you will have the misconception that it has not been read. I clicked RMB on some files on VBox with Win10, opened the Properties window and now I see that it caused an update of the last access time..
