Hi

Good job on the vid always love them :)

I just took the first step towards my dream of working as an engineer for the betterment of the world by starting my bachelors and I want you to know that your videos played an important part by motivating me and showing me what my goal is. Thank you!

One criticism - your assertion that lithium-ion batteries are used for the grid because they are best suited - the only thing they are suited for is easy on-demand load-scaling. I doubt we'd need even 3% of our grid storing to batteries if we supplemented it with physics batteries like pumping water into man-made reservoirs, and tapping into them later through hydro-electric. Not to mention, this tactic is much better for dealing with green energy's climate based output scaling which leads to imbalanced output depending on weather and season. If Elon Musk actually intends to go for battery-only instead of other types of energy storage, he's either stupid or intentionally playing for an agenda (or secretly hates environmentalists for being retarded which they are - there's no reason to demand 40 environmental impact surveys for maintaining existing infrastructure).

I think there is a mistake near ~3:50 where you say (electrons) "returns to the cathode" but it returns to the anode. Love your videos!

Well, roughly 2/3 of surface are under water. Of course there are going to be resources.

@@ThePrikoki The trouble with Hydrogen, as mentioned many times is that for every 10GWh produced, you only get 3GWh at the "point of use". Several ways to look at that. You face to produce 3 times the energy (90GWh) which is not only expensive to build, but at the moment *will not* be 100% "green", therefore it defeats the object, you might as well just use the fossil power directly. Cost to the end user. If that power needs generating, the utilities *will* pass the cost on. Logistics/ maintenance. Far more infrastructure and transport required.

Just hit it on the side with a hammer, it'll pop right open. Destructive disassembly.

Apple: 'Users shall not replace batteries' Every manufacturer ever: 'yes master..'

Fairphone. I agree it's crazy that being able to replace the battery became a commercial argument... At least, Fairphone may be almost as overpriced as iphones, but it's with the goal to improve reusability & working conditions in the supply chain, not to increase revenue of a bubling company. They just launched an improved version of their last model (better audio & cam), but instead of buying the whole phone I can just buy the new camera and replace it on my phone if I want.

I don't want to play the devil's advocate, but… why not use Apple's recycling program? Presumably you want to throw away your old phone anyways, so just send it in and they take it apart for you.

Battery recycling is the solution to many issues. It's starting to happen. Battery recycling won't hit its stride until there are enough 'used up' batteries to support plants. And Tesla batteries are lasting a long time. The EVs that have reached 200,000 miles still have over 90% of their initial range remaining, for the most part.

@@bobwallace9753 But what if recycling will be so expensive (even after all the innovations) that electric cars will become unprofitable? I am just wondering.

@@HaldirZero - that is the question?

@@HaldirZero recycling is cheaper than mining, and Tesla is already more or less profitable with mining:)

@@HaldirZero One of the founders of Tesla, J.B. Straubel, has started a company called Redwood Materials which is setting itself up to be a major recycler of used lithium batteries. This is only one of the companies that intend to carry out battery recycling. Elon Musk has stated that recycling will be the least expensive way to obtain materials to use in manufacturing new batteries. A used battery is basically a hunk of highly refined battery materials. Grind it up and separate out the different materials for reuse. Redwood Materials has started work with Panasonic at Tesla's Nevada gigafactory. They are recycling cells from the plant that aren't usable in EVs due to some manufacturing problem.

@pjd412 Hey PJ, sorry, I didn't mean my comment to imply the content wasn't great. That is why I love and subscribed to this channel, just that the time to make it look so good is also amazing as well. Having editing on the level of this and creating it from scratch with the custom animations is just a ton of work. Sorry if it came off like that, the substance is absolutely key here.

@pjd412 To be fair, James did say the content was amazing. I think that counts.

Tesla, and Elon Musk in particular, makes LOTS of claims. I'll believe them when I see them come true.

@@MrTaxiRob These aren't 'claims', these are numbers from their pilot plant already in production, and having been in production for months now.

@@ShneekeyTheLost you're talking about factories that they haven't built yet, therefore they are CLAIMS.

@@MrTaxiRob Okay, sure. Because the factories being built right now are somehow going to be *less* efficient than the pilot plant they've already got running. Suuuuure. Fun fact, that 10GW 'pilot' plant? Twelfth largest battery production facility on the planet, just to put it in perspective. So they're already producing these new batteries on the same scale that everyone else is, from a vastly smaller footprint. They just consider it a tiny fraction of where they intend to be.

Additionally, the tabless cell isn't new, it's just the first time Tesla is using it. Not fair to the original designers at Maxwell and other supercap firms to pretend it's someone else's innovation and spread misinformation.

lol that’s a Fair point! Obv One of the massive differences being emissions of a gasoline vehicle vs electric vehicle.

The amount of carbon producing the electricity released charging them is worse.

Funny and true

@@home2sky817 There isn't a massive difference in emissions between the 2. The electric vehicle comes out of the plant with a higher amount of emission cost compared to a gasoline vehicle. The gasoline vehicle does pass it over its lifetime but not by a lot.

@@samuelhowie4543 even if that's true today its a totally unfair comparison, it would be like comparing a 2021 corolla to a car from the 1920s. this tech is in its infancy and already is comparable to what its trying to replace? that sounds very promising to me. it needs more time, and its time will come.

ppl reuse this joke format so much that it doesn't even make sense anymore

Correction: Elon Musk: I forget. How many democratic governments are there in the world?

@Smoke Tree Tesla's new format 4680 battery cell has no cobalt. They increased the nickel content to compensate. They have a pilot production plant now. A full production 4680 battery cell plant will be built in 1 to 2 years.

Wanted to go into refinement and manufacturing more, but the video was already insanely long. May revisit this later

Are these elements more available in space?

There are no rare earth metals in batteries. Where did you get this impression?

Don't forget modern batteries are also pretty hard to recycle once their lifetime usage is over, which means that we are slowly moving form one problem to another as more and more current batteries are being used. Regardless of what Tesla likes to pretend it's doing, the real engineering of battery technology has a long way to go and a short time to accomplish it.

@@charliecrome207 yes, because space is much bigger than earth... but we are still a long way from starting mining operations in space

@IamtheFleecer nhhh, it's true for almost every commodity, from gold/diamond to textile/farming

And without mining, no electricity at all, we return to the dark ages, i ask people how far they are prepared to go to 'save' the earth, using facts to inform them of all the things they will no longer have access too, such travel, communication and education. It's amazing how many people do not actually realise what goes into making technology.

Most of these minerals do not require hard labor. If you’re thinking of cobalt, it is used for oil refining as well. The difference being that Tesla, GM, and others don’t buy their cobalt from Africa, but oil companies don’t care where it comes from.

The worst thing you could do, is to take those poor miners only source of income. If not working in the mines was was better than working in the mines, then they wouldn't work in the mines.

@@juliahello6673 You don't have any idea what you're talking about. Every oil company has an AML. Oil companies don't buy minerals anyway. They buy the finished product. You're doing the equivalent of blaming the Tesla car dealership for where Tesla get's its raw materials.

Presumably other OEMs are not going to get involved by starting with "solve all the world's energy problems on day 1." Any new competitor will need to do better than Tesla in some fashion, whether that's a new battery tech or new production methods or whatever they come up with. Certainly someone who is just starting to day and being a 100% clone of Tesla without doing anything different would face some significant uphill battles, but that's no different from a new competitor trying to enter any other market without something to make them stand out. As for competition more generally, most of the major automotive manufacturers have had a pure EV line to compete with Tesla for several years now, and hybrids are so common that companies barely even bother advertising that as a feature anymore. Similarly, competition in the battery sector is not trivial. Tesla tends to get all the credit in part because of Elon's high profile and their penchant for doing big, flashy things like the Australian grid installation, but in terms of researching new chemistries (which is the really important thing for the future,) there are quite a few people in both the private and public sectors pursuing multiple ideas to improve (or even replace) Li-Ion. Its not like Duracell and Energizer are going to sit their watching their markets dry up as Li-Ion becomes a more and more suitable (and rechargeable) replacement for traditional alkalines. And its not unfamiliar territory to either of those companies who have already had to fight a similar battle 30-40 years ago when NiCd (and later NiMH) started appearing in AA form factors. I think issues like the DRC's control over cobalt is far more problematic for the industry as a whole than Tesla's particular vision of the future. And their vision is likely 20+ years away from being realized even if everything goes perfectly for them -- plenty of time for competitors to join the market, for Tesla to change their vision, for nuclear fusion to be invented (its only 20 years away after all!), etc. This isn't something that'll be done and dusted by tomorrow.

@@altrag I was very interested about your analyse until you said 20 years for fusion. We are farrrrrr more away of having fusion energy.

@@ARCopros Yes its a joke. There's a common saying that "nuclear fusion has been 20 years away for half a century," or some such paraphrasing. Though we might actually be closer than the joke suggests. Certainly no guarantee, but the amount of private investment we've seen in the past decade is an interesting shift. Governments may be happy to pursue pie-in-the-sky ideas (especially if there's a potential military application) but private investors tend to be a little more cautious with their dollars. So the fact that we're seeing such private investment makes me wonder if viable fusion might finally be falling within that 20-year window they keep promising. (Of course, even if we proved one of the technologies tomorrow, it would likely take another 20+ years to scale it up from "viable" to "commercially relevant." City-scale power generation isn't cheap or easy no matter the underlying tech!)

@Strawberry Kiys Yes and no. Mines are absolutely terrible for the local landscape to be sure, but as long as tailings ponds are maintained and aren't allowed to leak their collected toxins into the environment, the overall damage from mines is very localized -- nature typically still remains undisturbed mere meters away from the edge of the mining operation. (Of course maintenance of tailings ponds is somewhat contentious.. mining companies have a bad habit of sucking out all the profit then abandoning the site entirely, leaving it up to the public coffers to continue maintenance for decades to come in addition to any ecological recovery we want to attempt. But that's more a legal problem than an environmental one.) Air and water pollution are more serious specifically because they can't typically be contained in any meaningful way. Once you've pumped your gas into the air or your chemicals into the stream, everyone (and everything) downwind/stream will be affected and there's nothing they nor even you can do about it after that happens. So no, nobody is claiming that mining operations are "clean," but if I had to choose between a hundred square miles of Peruvian mountain being dug out for Lithium or burning another hundred billion barrels of oil, the former is going to be the safer solution in the long-term. The area around that mine will quickly be reclaimed by nature once the mining is done. The CO2 buildup in the atmosphere will be around for possibly hundreds of years. And we don't really have the option of "do neither." We're struggling to convince people to switch to green energy -- a change that would be practically imperceptible in the average person's life. Convincing anyone at all (never mind everyone) to completely shut down our grid and go back to living in the stone age is.. just not really worth considering.

Is beneficial to Tesla that there is no competition

Thanks for the feedback on that!

😂😂😂omg you're savage

Hahahahahahhahahahahahahahahahahahahhahahaha

Yes, you are the only person, other than me, who caught this. Congrats on being "woke". Most aren't.

Yes and, The cathode is the positive electrode and the anode the negative electrode

The electrode of a battery that releases electrons during discharge is called anode; the electrode that absorbs the electrons is the cathode. The battery anode is always negative and the cathode positive. This appears to violate the convention as the anode is the terminal into which current flows

@@peterwilson9327 erm I spotted it as soon as he said it, but I am only watching this in december 20th

This always tripped me up before. From my understanding when the conventions were made they didn't understand that electrons were negative or something like that (they had no knowledge of sub-atomic particles). Still not quite sure how that came to be but it is what it is.

Although if the CIA and Elon had succeeded it would help but Lithium already comes from Nevada and Australia

then it's not too long.

It's so engaging if you are interested in the topic.

MSRs have large downsides that are conveniently avoided by those that champion them. Number one is that you have to have onsite reprocessing of the fuel mix to remove fission products. The cost of this is the primary reason that spent fuel rods are not reprocessed in most countries such as the U.S. Extracting and refining uranium ore (which is massively abundant in the U.S.) is cheaper then reprocessing spent fuel. It's a technology that has potential to be useful to certain places such as India that is poor in uranium but rich in Thorium. But it is not a miracle tech, nor is it magically more environmental friendly. That said I firmly believe we must explore, improve, and utilize nuclear power if we truly wish to cut down CO2 emissions as it and hydro are the only two reliable 24/7 power sources that don't release CO2.

@@Cragified That's exactly why RE should make a video on it.

@@madcio dude can't grasp the scale and depth of supply chain complexity.

@@LibertyDankmeme why do you even care what someone identifies as? I don’t think you should be fined or anything for misgendering though

I would suggest taking a look at mining uranium from sea water. Technically, it makes nuclear energy renewable for the next million years or so.

Working on a recycling video too. There are a lot of problems to solve. All the different chemistries makes it difficult to have a single process for recycling. Pretty much all the inventory available for recycling right now is from the Nissan Leaf, with nickel cobalt manganese, but soon there will be a huge range of chemistries. The main driver for recycling is recovering cobalt, and with the lowering percentages of cobalt in the batteries it’s becoming less economical to recycle.

But I guess recycling will be still useful for resource less nations like India where there is no deposits of battery raw materials. This would help is reducing the dependence on importing raw materials from other nations No idea about the recyclablity of materials inside a battery, your upcoming video will really help 😁 Thank you for the great knowledge.!

Tesla wont have any battery to recycle befire 10 or 20 years. Used car batteries are put in power walls or other larger grid rectification storage fields ...

@@InnocentEX being technically correct doesn't mean that you didn't intentionally choose a manipulative term.

@Trumps Wall would know where to start

He actually missed the most crucial part about the new battery construction - due to tabless design new batteries are planned to be few times more energy-efficient than current ones. This may solve all the other problems with material scarcity etc. So the whole video is either a bit of propaganda about how tesla is worse than it actually is or Brian is worse at engineering than at making videos.

this one is worth checking out : ukposts.info/have/v-deo/b6mfqaaQeYKd2nU.html

Depends really, an electrolytic cell has a positive anode and negative Cathode, while a galvanic has negative Cathode and positive anode. During charging, the battery becomes electrolytic. During discharge, battery is galvanic.

the cathode is positive in a battery, electrons flow into it and charge flows out.

@N Satheesan what you're thinking of is a primary cell battery. An irreversible reaction providing a voltage and is only a galvanic cell. The batteries in question are not primary cells. They are secondary cell batteries. Meaning they are rechargable and exhibit both galvanic and electrolytic behaviour in the discharging and charging process.

@@minaolenella869 Public transportation would be good, and should be increased, but I feel what will have the biggest impact is self-driving vehicles.

Well, in chemistry anode is electrode which facilitates oxidation.

@@Kycilak Yes, oxidation occurs at the Anode, which is the positive electrode. (Conventionally)

@@JesusHChrist2000 Nope, depends on what the cell is doing. As a source of voltage it has swapped polarity to electrolysis cell. Also the direction current flows by convention has nothing to do with polarity. The + and - stay the same in a given circuit whether you suppose positive or negative charge carriers.

@@Kycilak Ok? But the explanation of batteries in the video incorrectly shows Cathode as positive and Anode as negative is all.

Yes this had me confused too. I would have assumed an error (the cathode is the negative electrode in every context I've ever encountered) but Brian researches stuff thoroughly.. so went back to Google and I believe he's right in the context of lithium ion chemistry.

The most obvious issue is: it needs to be compressed and this means energy loss. Also some of the parts needed in hydrogen duel cell are also not cheap, is my guess. But it's not the only option, the Wikipedia page for hydrogen storage is long. Some hydrogen plants for grid energy storage do exist: Canada, Germany.

From what I know, hydrogen extraction from water is extremely unefficient compared to other storage methods, which is the reason why hydrogen is very often produced from oil. But with more research, who knows what could be possible in this sector?
