Worldwide electric grid. Solar is all you need.
You mean run a few loops around the equator and wait for solar wind, or what?
I have a PhD in material science and worked with superconductors, here are two things that is often misunderstood: 1) it takes a undergrad to make and measure a superconductor but a Nobel laureate to explain it. 2) in theory if you understand the mechanism of something you can improve it. In material science however almost always all you need is a trial and error approach to end up with a good result. Conclusion: the…
Is it science if you essentially fiddle something until you get a result you are after and then try to fit a theory that would explain the result of the fiddle?

"Finally, the calculations presented here suggest that Cu substitution on the appropriate (Pb(1)) site displays many key characteristics for high-TC superconductivity, namely a particularly flat isolated d-manifold, and the potential presence of fluctuating magnetism, charge and phonons. However, substitution on the other Pb(2) does not appear to have such sought-after properties, despite being the lower-energy substitution site. This result hints to the synthesis challenge in obtaining Cu substituted on the appropriate site for obtaining a bulk superconducting sample."

love the atomic full screen button on the video player XD

I'm not hearing much argument for why I might be wrong, other than pearl clutching, tone policing and guilt by association
Your arguments aren't unique by a long shot; you're simply witnessing two seperate people who have been discussing technical matters since pre-WWW Usenet days observing there are hackers who have been making those arguments for 40+ years.
I can't speak for Don but for my part they got dull 35+ years back.
I'm sure you can find a rebuttal or reinforcement, whichever you need, elsewhere.

Time to invest in lead futures?

https://targum.video/v/2023/8/1/2534a4408ccce9c13a811e94f16d... Targum translation. From the comments and video it seems he claims levitation of a micron sized particle. Not sure if it is fake or not.
He repeatedly stated that the sample stands up(become straight) when the object is nearing it, and drop down when its far. The same applies for the negative polarity(same behaviour on N/S). Source: Native Mandarin speaker.

Doesn't anyone working in the physical sciences know how to record a decent video that isn't shaky, blurry, out-of-focus, or a handheld mobile phone recording of a computer screen? He's using a digital microsocope! Just press the "record" button and upload that! I can't wait for someone to successfully reproduce it, use a polaroid camera to take the photo, print it out, fax it, and have someone scan in the photocopy,…
Imagine you have dreamed of some new discovery your whole life. Let's say you are convinced that, I don't know, there exists in the world a naturally bright pink species of cat. You study cats; you know their behaviors, and can guess at the means of finding this elusive pink jungle cat. You search for years to no avail... when suddenly, without prior warning you are on vacation in some remote island and hear a rumor.…

> 1) it takes a undergrad to make and measure a superconductor by a Nobel laureate to explain it. Another example of Taleb’s idea that experimentation comes first and theories second. Universities pretend that it’s the other way around but apart from an Einstein it’s usually not.
Not possible. Theory comes first. Scientists need a theory first to know which experiments to do. Any interesting experimental results are interesting precisely because they do not conform to the existing theories. Edit: here's a decent writeup to show what I mean https://en.wikipedia.org/wiki/Theory-ladenness
We had the first theory on how they operate in 1920s. Eventually we got transistors from that theory in 1950s.
