Which business do I invest in assuming this is real and has IP protection? It would be like buying Intel in 1971 or getting shares in Edison in 1878.
No company listed.

Two, people touch their solder and then grab a cookie. We're premature. The results need to be proven. But the benefits of RTP superconductors is mindblowingly high enough that risks from lead contamination (far from a novel problem, I might a…
Soldering temperatures don't produce significant lead fumes. The fumes you see are flux fumes (which are also bad to inhale). IMO, the most dangerous thing about lead solder is cleaning the iron. Both the common methods (damp sponge and brass wool) create many tiny little balls of solder that are hard to see and bounce about all over the place. Because of the high density of lead they're less affected by air resistan…
The last time I checked, low-temperature bismuth-tin alloy is only available as solder paste, unfortunately not available as flux-core solder wires (they're not really a good choice for connectors to begin with as the alloy is brittle, but I only need it to survive before the next prototype...)

I've forgotten how many times one of the most important thresholds in our times has been bumped up a bit. Now we seem to be offered heaven on a plate. If superconductance can be reliably demonstrated at RTP (you wear a light cotton shirt, instead of 1cm thick fancy weaves involving an awful lot of rubber) then we are laughing all the way to ameliorating climate change. Even if this result is confirmed then I think it…
How would superconductivity help to reverse climate change? Honest question.
Of course, there are huge hurdles to such a project even if we did have the superconducting lines, but there are more realistic similar applications that might actually work.

> we succeeded in synthesizing the room-temperature superconductor (Tc≥400 K, 127∘C) I'll say, for "room temperature", that's certainly no room I'd want to be in.

I believe the biggest envisioned possibility is superconducting power lines. Those would allow long-distance power transfer with minimal losses. In the most idealistic scenario, you could imagine a belt of solar power plants around the globe connected by superconducting power lines, providing solar power 24h a day. Of course, there are huge hurdles to such a project even if we did have the superconducting lines, but…
We can easily generate more than enough renewable energy, just not when and where we need it. Being able to transmit energy over vast distances would greatly improve the economics of our existing renewable energy generation solutions.

I'm just going to link the comment I wrote above :) https://news.ycombinator.com/item?id=36867709 Needless to say, this would be game-changing. But extraordinary claims require extraordinary evidence etc, let's be cautiously optimistic here.
Thank bro! are we talking like no heat loss in the traces on the motherboard type a deal or also on a wafer level internal to the CPU?
Ideally, this could be useful for the hottest paths: clock tree, high-speed buses, as well as the power supplies.
There are a few hurdles though: high-speed voltage changes create changing currents, which creates variable magnetic fields, which IIRC may be a problem depending on the superconductor's characteristics. Processors also work at low voltages, which means that they need huge currents. Both magnetic fields and large current (as well as high temperatures) can break down superconductivity. So it's challenging, but probably doable.
There are also superconducting structures that could replace transistors, see applications of https://en.wikipedia.org/wiki/Josephson_effect

I found that video very compelling. If it was eddy current, the float standoff distance would have decayed. It sure looked to me like there was no decay at all, and wow! if true.
What is float standoff distance?
I've linked to a relevant example in a Veritasium video here: https://youtu.be/g0amdIcZt5I?t=543
But in this sample video, the standoff distance doesn't appear to be slowly dropping at all, which would rule out eddy currents as a source of the behavior. If you continue watching the linked video to 13:27, he talks about how and why superconductors levitate.
I severly doubt that it is an actual room temperature superconductor, but would love to hear the opinions of more well informed people on that topic.
127°C, so it is room temperature if you first set your room alight.
