    • 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).

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.

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.

  • Some things to point out: * There are three chemistries Tesla called out as being used concurrently in their new battery production based on the 4680 'tabless' design: LFP (iron/phosphorus), Nickel Manganese, and High Nickel. All three chemistries eliminate Cobalt entirely going forward. * They specifically called out LFP for grid-level storage in their Battery Day presentation, which not only has no Cobalt, but has no Nickel either. While there are still issues with LION batteries as grid storage, and liquid metal batteries are a promising theory, a drain on Nickel resources is not going to be among them, at least for Tesla. * You quoted the number of factories they would need with the older production lines, but you completely ignored their new production chains that reduce footprint tenfold, and that a single plant making the new batteries of a similar size to the Gigavolt plant in Nevada (and the ones currently being built in Texas and Berlin), would produce closer to a full TW of battery production, meaning less than a dozen of these would be needed. That's the sort of scaling efficiencies they are attaining in their pilot plant.

    @jacdragan8918@jacdragan89183 жыл бұрын
    • 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.

    • @@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.

    • 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.

    • It depends on what reserve hes talking about. There are Proven reserves which is the Sum total of accessible materials and reserve capacity which is when a mine operates at lesser capacity then possible. The problem in the video is he uses them interchangeably without mentioning which reserve hes talking about. IE: the Indonesia mines running at less than capacity. and the Cobalt mines in the DRC which are running at near capacity.

    • @@caliph20 Actually: THE vid host doesn't have a damned clue and bollixed it up. Reserves are those economically able to be mined. Period. Definition used by everyone for the history of the mining community. Strategic reserves are amount of mineral set aside in storage... No one has this other than a very few select countries and they are ONLY there for military purposes and have nothing to do with civilian life. NO mining company EVER states what their mining capacity is. And nickel mining companies the world over are seeing DRASTIC push back from local people for environmental reasons. Phillipines has effectively killed off their Nickel mining operations because of the horrific effects. Australia has large reserves of Nickel, but effectively mines very little of it. So, TESLA, if they actually WANT Nickel, you have 2 friendly nations more than willing to mine it, if one PAYS for the environmental side of things. Same goes for Canada.

    • @@w8stral Well, yes. But, giving the guy the benefit of the doubt. Within the video he speaks of companies not mining due to supply/demand curves with companies choosing to leave capacity unused within the context of a "reserve" So, sometimes hes talking about this. Other times he is specifically mentioning proven/probable reserves. Like the Cobalt. *12 years value etc* I think he couldve done a better job of differentiating the talking points.

  • Where it's possible, pumping water uphill is a pretty effective energy storage system.. already in the 1960's Switzerland reversed the turbines and generators at night to pump water uphill at night when grid demand was low, it may not be as efficient as charging a battery (I haven't done the math), but it should achieve at least 60% overall, but it requires far fewer limited resources to do, especially with well chosen locations

  • We need to make personal transportation much much smaller and lighter. Pushing heavy cars around with batteries is not scalable. Electric city trolleys need to come back in a big way. Direct grid powered transport is the only way to solve these problems. Small vehicles with capacitor pacs to cover the small gaps between road grid source lines is the way to go. Basically a personal trolley with a small capacitor pack to push the vehicle between power lines.

    • small vehicles would be able to ride only on smooth city roads, and why would you need personal vehicles in cities at all? Public transport is faster and more reliable in most cities. And direct grid powered transport has not gone anywhere, most big, and not so big, cities use it constantly.

    • @@minaolenella869 Public transportation would be good, and should be increased, but I feel what will have the biggest impact is self-driving vehicles. We will need significantly less vehicles on the road if they can drive themselves to serve people instead of sitting in a parking lot or garage for 97% of their life. This equates to much fewer raw materials and a host of other benefits. Honestly, I think self-driving cars will be very major in our fight against climate change and I don't see people making this connection enough. Thoughts?

Investing in thing like free scholing for children in affected area’s, agriculture scholing for adults to make a living growing enough food, investing in systems like solar energy + battery so people can work at home when it is dark etc, That will help with ending child labour. Stopping making batteries with cobalt is not the solution for child labour.
