News Superconductor Levitates At Room Temperature, But Questions Remain

[Admin]

Scientists with the Huazhong University of Science and Technology have replicated LK-99's levitation abilities at room temperature, which they showcased in a video uploaded to Billibilli.

Superconductor Levitates At Room Temperature, But Questions Remain​

No-no, that's good for me. Carry on.

Anyone found any examples of basic journalism on the subject ?

Like someone going and actually talking to the original researchers and asking them about their groundbreaking work? and why it was published in such an unorthodox manner.

We have their names and know their University affiliation.

I understand it might not be quite as cool as watching science tick tocks. But possibly informative.

I think the "superconductor could limit a power grid's losses" argument is silly.

We currently lose far more than that 10% power loss from resistance, due to simple overcapacity from intermittent energy from wind and solar.

If governments cared about grid losses we would be turning that energy into hydrogen instead of shutting off wind turbines.

Or for those of us on the "ring of fire" geothermal power.

That said, with the eventual push for electric vehicles (or at least plug in hybrid) + at home / in building power storage (think Tesla Powerwall) overcapacity loss will probably become a thing of the past.

That's not even accounting for the increased demand for heating / cooling as this wonderful climate change keeps giving us more extreme weather.

We presently have high current DC power lines that arc cryogenically cooled in order to reduce overall system cost. We aren't looking for one silver bullet that solves all of our issues. It might turn out that this discovery is totally useless for power transmission, but it might also result in frictionless travel on interstate highways facilitated by magnetic bearings. It could be used in an unexpected way by increasing the efficiency of internal combustion engines, giving us a Chevy Tahoe that geta 100mpg using a gasoline engine.

The probably with hydrogen is that it is very hard to store being such a small molecule.

If you fill up your car with gasoline you can be confident that if you come back in a week youll have very close to a full tank.

With hydrogen that won't be the case.

With hydrogen that won't be the case.

Hydrogen + carbon monoxide = liquid synthetic fuel you can just as easily store and transport as diesel or gasoline. And it's CO2 neutral.

Hydrogen + nitrogen gas = ammonia which is easy and safe to store and transport.

Sure, that extra step to store hydrogen in a different carrier costs more energy, but currently overcapacity from intermittent energy, especially offshore wind that can generate a lot of energy on windy days, is literally going to waste.

European countries are starting to build islands next to offshore wind to store hydrogen though, so the energy stops going to waste.

If this is genuine, better known, respected institutions will replicate it. Then, in time, finds ways to make use of it. However, I am also sceptical.

Would not be surprised if it's legit, this "race" started as soon as USA made the aliens disclosure

It's called LK-99 because it was discovered in 1999, 24 years before any "disclosure".

It was so obviously promising that they didn't get around to filing any patents until 2020, 3 years before any "disclosure".

The "aliens disclosure" was not made by "USA", but by 3 individuals. If they'd actually released anything useful -- like the chemical formula for a room-temperature superconductor -- then they might have been given more credence, but their 'evidence' was that they heard other people say something about aliens ... so nothing but "trust me bro".

Personally, I would be surprised if they have anything whatsoever to do with each other.
