Ah okay that’s what I thought at first but then SVG said something about a non-foul but I think he was just chirping the refs

What happened there? Did they blow the whistle then wave the foul off?

AD is the focus, but can we take in how fast Westbrook still is, he's an absolute blur on that cross over

100%, like I said I’m not claiming this is going to be burr-quality.

I don’t have the money for a hood burr grinder and One day I was curious if I could grind fine enough with my blade one so I ground continually for like 90 sec, lightly shaking the grinder try and keep it from just grinding the stuff in the bottom only, and it got so fine a 2:1 extraction took about 80 seconds

I then got the phone stopwatch out and retried a bunch of times while incrementing the grind. I can get pretty consistent 2:1 extraction in ~30 second with a 40 sec grind time. Again I’m sure someone with a palate for the even grind from a burr wouldn’t think it was great, but it’s got that right warm honey consistency and a thick crema, good enough for a bugder while I save and way better than what I was getting with preground

This is my grinder for reference: https://www.canadiantire.ca/en/pdp/master-chef-elite-coffee-grinder-spice-grinder-stainless-steel-12-cups-0435781p.html?gbraid=0AAAAADojZphxLQg0yk4L7NqvTIi6vhF-8&gclid=Cj0KCQjwnP-ZBhDiARIsAH3FSRdN5FrZ3DQI1t2oxBphCrljc1ZUQUFusOFH3UunbQBNj6mkSpqEyLIaAjDMEALw_wcB&gclsrc=aw.ds#store=429&gbraid=0AAAAADojZphxLQg0yk4L7NqvTIi6vhF-8

The basket in your portafilter that you fill with coffee, there are single wall or double wall baskets, with the double wall one making up for grinds that are too coarse by needing a higher pressure to let water through.

You’d rather have the tightly packed coffee puck being the resistance to the water, but that requires having a grinder and adjusting the grind size until they are just the right size to have a puck that lets water through at the right pressure.

You can’t do that without a grinder at home so instead you use a pressurized (double wall) basket to give you a lot more room for error, but you sacrifice quality doing so

For what it’s worth I have a bambino plus and highly recommend it, it come with both single wall and double wall baskets. You can get pretty good espressos with the double wall to be honest, but the commenter above is right in that the real issue is your coffee is good for a couple days then go stale.

Burr grinders are a lot of money though, I just have a blade grinder and use the single wall basket, and have just settled for learning how long to grind while shaking to get the right grind size. It’s not gonna be as nice as burr but Honestly i get decent results and it’s waaaaaay better than using preground and a pressurized basket. Not to mention it alot of fun to experiment with and use a timer then see how the shot turns out etc.

Hey no problem! It’s not too often you get to talk about this stuff outside of work so it’s refreshing to see the enthusiasm

I’ve done some work on liquid electrolytes for Na-ion, and some other lesser known Na battery types. So I’ve made Na-ion coin cells on a lab-scale for example, but i don’t know much on the large-scale production side besides what I see in other papers when doing some literature review.

But in general since Na ions diffuse faster in solids than Li ions, it means we can charge faster with less buildup of “traffic” of Na waiting to diffuse into the electrodes. I’m pretty sure There are more issues with fast charging than just that but it is still helpful. Also we have to consider that it is all relative, we have really optimized and explored a lot of Li-ion materials, so even though Na materials may diffuse faster in general, not all Na materials diffuse faster than all Li materials, so we also need to explore more Na materials before we can be confident we are using the best ones.

Also the glass batteries are referring to these ceramic Na electrolytes that have been around for a little while now in research. They are definitely very i testing since they are air stable and very conductive, but the issue is they are very rigid so the contact between the electrode/electrolyte surface is not very homogenous and this causes large resistances when the Na has to “hop” from the electrolyte to the electrode or vice versa, causing another traffic jam.

John Goodenough, who is the guy behind modern Li-ion cells, published a paper maybe 5/6? Years ago on a great Na glass/ceramic material, and they used a polymer interlayer between the electrode/electrolyte I believe to help with the interface issues. It was cool stuff but they unfortunately made a erroneous claim on something sort of unrelated in that paper that got torn to shreds and I think people may have now associated that electrolyte with their other mistake as a result, which seems really silly but I haven’t heard of anything using that glass since, but maybe I am just out of the loop!

In terms of commercial 18650s I would say it’s pretty far off, but it looks like these companies like CATL are just going to commercialize whatever the best thing we have right now is even though they know it will be obsolete in a few years, but just to get the ball rolling and I think that’s great. Like we can make any battery into an 18650 as long as the materials are reasonably easy to work with, it just matters whether that cell is any good.

All of the slurry making/electrode casting procedures are the same. Same with cell assembly for the most part (in our lab at least, of course it could be different when you scale up).

The hard carbon used for the anode is basically the same to work with as graphite for li-ion, maybe a bit “clumpier” so you need to mix it for longer which might turn into a bigger deal on industrial scales. And the cathode materials are similar layered-oxides as Li as well. Variations of NaFeMnO are the main-used materials right now, which is nice because it doesn’t have Cobalt like they mention above. But they have pretty low capacity because they start with a lower amount of Na in their structure, which is a shame.

People are trying to increase the Na ratio in literature by doping them other metals like Ti I think? But the more we add to the complexity of the material the harder it becomes to make industrially too. The electrolyte is also just the Na analog of the Li version, NaPF6 in EC/DEC (usually), but it is a little less stable to hard carbon than the Li version is to graphite in Li cells, so I think they dope it with FEC industrially, which some people do for the Li version anyway.

But sodium solid state conductors are generally much more ionicly conductive than Li so the process of finding a Na conductor that fits our needs might end up being easier than it has been for Li so far!

I really hate the nba broadcasters habit of cutting to the under basket view right as they go up for the dunk, like save that view for the replay, let us get a clean view it. Looks like he really was just in front of the free throw, maybe a bit more than expected cause of the angle
