Re: [Vo]:Depressing article about ITER
ITER is bunch of crooks that enjoys wine & dine in south of France. The physics behind ITER is just garbage and has been experimentally refuted since more than 5 years...You cannot contain a plasma at such high temperature due to radial instabilities - the same problem Randal Mills did face with his table top fusion machine (now called SUN-CELL) that still holds the wold record for >1 minute self sustained fusion...(with no radioactive garbage..) Wire your MP's to stop all finances immediately and convert ITER into a science Crooks museum. J.W.

[Vo]:Depressing article about ITER
https://www.scientificamerican.com/article/worlds-largest-fusion-project-is-in-big-trouble-new-documents-reveal/ World’s Largest Fusion Project Is in Big Trouble, New Documents Reveal The International Thermonuclear Experimental Reactor (ITER) is already billions of dollars over budget and decades behind schedule. Not even its leaders can say how much more money and time it will take to complete By Charles Seife on June 15, 2023 QUOTE: It could be a new world record, although no one involved wants to talk about it. In the south of France, a collaboration among 35 countries has been birthing one of the largest and most ambitious scientific experiments ever conceived: the giant fusion power machine known as the International Thermonuclear Experimental Reactor (ITER). But the only record ITER seems certain to set doesn’t involve “burning” plasma at temperatures 10 times higher than that of the sun’s core, keeping this “artificial star” ablaze and generating net energy for seconds at a time or any of fusion energy’s other spectacular and myriad prerequisites. Instead ITER is on the verge of a record-setting disaster as accumulated schedule slips and budget overruns threaten to make it the most delayed—and most cost-inflated—science project in history. . . . -- You received this message because you are subscribed to the Google Groups "CMNS" group.

If the diameter is about 1 cm, then the circumference is about 3 cm, multiplied by a height of about 1/2 cm, gives an area of about 1.5 sq. cm, not a fraction of a sq. cm. However, I suspect that the concept of area is a bit irrelevant at the atomic scale in a battery, as the ions actually migrate into one of the electrodes in a Lithium ion battery IIRC. In short, I wouldn't trust these figures. [snip] Buy electric cars and recharge them from solar panels on your roof.
Re: [Vo]:Dr.s Using ChatGPT to Sound More Human(e)
There was an incident recently at the National Eating Disorder Association (NEDA) website, in which ChatGPT gave bad advice and was turned off: https://www.cbsnews.com/news/eating-disorder-helpline-chatbot-disabled/ Based on my experience setting up the Bot at LENR-CANR.org, I expect some technical glitch caused the bot to malfunction and give out the wrong information for anorexia. I expect they uploaded the help-desk files at NEDA, and those files probably have the right information, but the bot did not find it. A lot can go wrong during setup. The data has to be structured in certain ways, and it has to be in the correct format. At LENR-CANR.org a glitch caused the Bot to lose half of the files. You have to understand and adjust various parameters such as the "AI temperature." Like all newly emerging software, ChatBots are unreliable and prone to glitches. There are no proper user manuals or installation instructions. A bot should be tested extensively before releasing it to the public. Especially before releasing it to patients who are worried and vulnerable. The larger question is: Should we be using Bots to hand out medical information and other potentially harmful information? I say yes, we should. It does not seem any different from posting web pages with medical advice, such as this one about anorexia at the Mayo Clinic: https://www.mayoclinic.org/diseases-conditions/anorexia-nervosa/symptoms-causes/syc-20353591 Then again, maybe we should not use Bots just yet. Two reasons: 1. They do not work well (as I said); 2. People have the mistaken impression they are intelligent, or even sentient. People may have more faith in what a Bot says than what is written in an ordinary web page at Mayo Clinic, or in a library book about diet and health. In a few years, people will be used to ChatBots and they will know that a Bot is just a convenient way to find and summarize what you want to know. They are not omniscient super-intelligent beings. Bots are extremely useful for many purposes. The other day I wanted to know how many watt-hours an AAA battery produces, and how big the electrodes are. The Bard Chatbot told me: A lithium AAA battery electrode is: - Diameter: 10.5 to 11.6 millimeters - Height: 4.8 to 5.6 millimeters - Positive electrode surface area: 0.1 to 0.2 square centimeters - Negative electrode surface area: 0.2 to 0.3 square centimeters Output is 2500 mAh or 4.5 Wh. It was faster and more convenient than scrolling through Google search finds. I assume it is right. I should check, though. If it was for a serious purpose, I would check.
