This is Sony, so their electrical engineers clearly know what they are doing. But at the same time I can't understand how such a thing works using pure white noise. Feynman famously described (and disproved) a similar energy-harvesting

This video ( https://sciencecast.org/casts/suc384jly50n ) showing the Meissner effect should be the easiest to replicate: just send a sample to another lab and put it over a large magnet. As far as I know, the only expla

That's not the video I'm referring to. It is a different experiment from Fig 4b in the paper, which is showing magnetic levitation. I agree with swamp40: the video you linked is not demonstrating the Meissner effect, and is just s

A sister paper [0] has a photo of the material exhibiting the Meisner effect and levitating over a magnet, and claims to have a video too. Either they blatantly photoshopped the photo or they actually made a room temperature super conductor

Thanks for sharing your experience. To what extent do you trust Finkel‘s writing here?

I don’t know either, and hopefully someone here in journalism can comment on how serious it is to do what Finkel did. I like how the New Yorker Book Review article (recently on HN [0]) reviewed both the book as well as the author. I thought

If some of these stories seem a little too fantastical to be true, it’s possible that they are. Michael Finkel, the author of this article was fired from the Times in 2002 when he admitted that a character profile he had published was actua

For those of us who would like a little more depth in the history and chemistry of automotive paints (and more images/videos too), there's a great video essay by New Mind on youtube: https://www.youtube.com/watch?v

Funnily enough, there wouldn't be any "depletion from the ground" in the substrate either. If the charge in the substrate was removed and sent to ground, the charges in the gate would also disappear and be sent to ground simu

This article is completely wrong. For every electron you place in the floating gate of the transistor, an electron is removed from the bulk or substrate of the device. The net weight is exactly the same, you are only moving electrons within

Is the heat transfer fluid for these nuclear plants considered radioactive? I honestly don’t know. If so, then if a leak happens I’m guessing you have bigger problems than its chemical reactivity. Any leak is a major nuclear cleanup whether

It's sometimes amazing to see how history rhymes. At the dawn of the industrial age people had similar reservations and worries about thinking machines just like the AGI worries we see today. Side note: This essay was inspiration for t

The significance of the original image was in verifying that our laws and models of black holes truly reflected reality. This AI enhanced image used simulations to guess at the missing data. Doesn’t that defeat the purpose of the black hole

I totally agree- that's why I think we need better branding and marketing in stores. I personally like the Costco model of "do the research for the consumer and give them limited choices" but it's easy to see how this co

The irony of this article is that the author is suffering from “too much choice”. LEDs have so much more capability than fluorescent and halogen bulbs that the burden has fallen on the consumer to sort out what dimmability, temperature, and

In addition to the problem of measly human power (mentioned in other comments), generators are only efficient when the magnets are quite close to the conductor so the metal pots/heating element would have to be held ~2mm from the rot

I am a medical student and biotech researcher. My lab does cancer diagnostics. In a certain sense, money can be used to solve all solvable problems since it buys people's time and expertise. In that sense, your question can be rephrase
