There are plenty of commercial applications of hydrogen fuel cells though. The biggest issue has been pretty much a constant over the time since it has been invented: keeping the membranes free from impurities is hard. But there are all kinds of transportation devices using hydrogen in production today.

Sure, but the point is that they hardly caused a revolution in energy storage. If fuel cells didn't exist, for the average person life would be exactly the same. Revolutionary tech does change normal peoples lives, and sometimes very rapidly, but a lot of stuff that looks revolutionary just kind of never works out. I'd say nuclear power is probably the prime example of this. It was supposed to bring us electricity to…

Fusion, specifically, is meant to be the one 'too cheap to meter'. The thought being it'd be ready soon, and grouping both kinds of nuclear together worked as better branding for getting govt. funding.

Reminds of "command line is faster than GUI" folks who get timed doing every task slower. "But it feels faster!"

Every task? If I want to rename all of the .pdf files in the folder to .avi I would just do it in the command line Or would you rather have me google a GUI that lets me "quickly rename" and download a few programs that have this capability? Or do a few hundred files by hand?

The GUI for that is called file manager, there are quite a few available and they can be far more sophisticated than an ad-hoc command pipeline. If you manage your files on a regular basis (manual sorting, metadata, mass renaming etc), you already have a serious file manager that allows you to do this.

Command line is... fine for doing this occasionally, but it's hardly "quick" or usable for this, I'm saying that as an advanced commandline user. You're just using the tool that you already have and know, and it happens to be the system shell. It doesn't have to be.

(another question is that classic file management at the scale where a sophisticated tool is needed is mostly automated nowadays, and yes there's scripting as well)

How would superconductivity help to reverse climate change? Honest question.

Fusion power require powerful magnets(essentially super conductivity is a requirement). Currently the best contender for commercial fusion is REBCO(see: Commonwealth Fusion Systems). With cheap fusion power, we can begin pumping that CO2 back into the ground and forget about using fossil fuels for energy entirely.

Instead of pumping CO2, why not biochar?

If you are curious what the betting markets think,

Manifold Markets is hovering around 30% with 225 traders that it is replicated before 2025.

What's your point?

Are you living in the fairy land? in the real world, Academic fraud is a thing.

What's the point with academic fraud at this level? If it's fraud, then what did they expect other than career suicide?

As someone who doesn't follow superconductors, what sorts of things about life/engineering/society would change, how dramatic would it be, and more importantly: which stocks would you pick :)

One thing I can imagine is desktop MRI machines, or, at least, much cheaper and less finicky big MRI machines that don’t take days to chill to operating temperature. Maglevs are also a popular guess - safer, faster, and more power efficient ground mass transport would be a huge thing. Maybe even magnetic rail space launches. And, of course, military applications (the last few examples I mentioned involve acceleration…

Those are two I see mentioned the most often (MRI and maglevs). To be honest though, those are great things to improve (especially the MRI), however, the amount of hype in this thread and on the internet tells me there must be more than just improved MRI and better trains....

> if you consider 10e-5 torr vacuum to be trivial Its not hard to achieve at all. Electron beam welders at work have 1E-6/1E-7 in the E-gun chamber all day long held by a little turbo or diffusion pump. The chambers aren't made from anything exotic just stainless steel and/or aluminum with viton o-rings. My little e-gun experiments are all done with a Alcatel Pascal 2008 and I can achieve ~3E-3 with just that pump. I…

What on earth are you up to? :)

Nothing crazy ;-) Actually I'm just playing with plasma electron sources for heating/welding/melting.
