@mcfellaface Oh man, I forgot all about the #Demoscene! Haven't watched a #demo since the mid/late 1990s - #FutureCrew and all of them. What people managed to fit into a couple dozen K (or even just a few K) was staggering, and simultaneously (A) inspirational and (B) giving a sense that I'll never be that good at coding ;)

@[email protected] @davetroy @Tnicholsmd And to be explicit, #Tesla wasn't "bought out". Tesla was a shell company. It had no tech to its name - it was all ACP's. It didn't even own the trademark to its own name. No money changed hands. And - key point - ***#Eberhard was independently wealthy***. He had recently sold his compan NuvoMedia to #Gemstar for $187M.

@[email protected] @davetroy @Tnicholsmd Sorry, but this is revisionist history.
Both of #Musk's' early companies were mergers between pairs of startups, but he was *absolutely* working on them on his own at the time of the merger. #Paypal Inc was the merger of Musk's X.com and #Thiel's Confinity. And when Elon and #Eberhard merged their forces, #Elon was already working on a converted #Noble with ACP's powertrain (while Eberhard was working on a #Lotus with ACP's powertrain).

@Timmy #Tesla is the first company switching to a vastly more compact (and thus cheaper / faster to build) dry process. It's already in use in some of their vehicles at #GigaAustin, but it's been a long hard slog to bring it into production, and it's still small scale (dry process sounds so simple but there's tons of bedevilling details).
Hope that helps!

@Timmy ... (#plastic) separator membrane. Beyond all this, there's a variety of minor additives, as well as the small amount of #lithium itself.
The main limiting factor in scaleup however is none of this; it's plant capacity. And in particular, film synthesis for the jelly rolls. Traditionally this is done with a wet-phase process, but this requires #VacuumOven.s the length of a football pitch for each line to extract the #solvent.

@Timmy While there's lots of #nickel out there, the rate of scaling up battery-grade nickel production is believed to be slower than the capability to scale up #LFP production, hence the expected shift to LFP in the coming years.
So we've now covered the #anode and #cathode. The next greatest bulk comes from the casing (#steel) and the #electrolyte (mainly organic carbonates - a #petrochemical product). After this comes the #alumium and #copper current collector foils, then the...

@Timmy (2) #cobalt is already used in a wide variety of things, even #oil refining itself.
#Nickel is the bulk of the long-range #cathode.s, and indeed, its limiting mineral. Most of it today goes towards making #StainlessSteel, where it's a major alloying agent (alongside #chromium). Globally, #Indonesia is the biggest producer; in #NorthAmerica, #Canada is the biggest, thanks to the #Sudbury bolide deposit. #Australia has the largest resources.
-
@Timmy No need to discuss #alumium or #manganese (if you're not familiar with the latter, it's the most common alloying agent in #steel - it's everywhere).
#Cobalt usage has been steadily declining (a couple decades ago it was as high a % as the #nickel), and there's hope it will be entirely eliminated in the coming years - but as for now it's still in use. Cobalt is the most expensive of the metals (offset by its low percentage), which is a major factor driving the work to eliminate it.
-
@Timmy As the #LFP patents have been expiring, and it uses no nickel, its use has been increasing dramatically (despite giving lower range, and some other disadvantages).
For longer range, one uses, as mentioned, the nickel-based chemistries. These #cathodes are mixed metal oxides, usually in the ballpark of 80% (or higher) nickel, 10% (or lower) #cobalt, and 10% (or lower) #alumium or #manganese.

@Timmy again, 100% production limited, not resource-limited - indeed, synthetic #graphite can be literally made from anything at all that contains #carbon).
The two main mass components are the anode and cathode bulk materials - the anode, as mentioned, being graphite. #LFP cathodes are made of iron phosphate, which is basically #fertilizer. Very cheap - react #iron (the most common industrial metal) with #PhosphoricAcid (one of the most common industrial acids).
-
@Timmy Of course, pointing out that #liion #batteries are only 1-3% #lithium automatically raises the question, "Okay, then what are they made out of?" And there's two major groupings at present. Shorter-range #EVs tend to use #LFP (Lithium Iron Phosphate) while longer-range EVs tend to use #NMC (Nickel Manganese Cobalt) or #NCA (Nickel Cobalt Alumium). These terms describe the #cathode - the anode in each case is #graphite (either natural or synthetic)

@Timmy Contrary to popular myth, lithium is quite abundant. In the crust, it's more common than lead, and more importantly, concentrates nicely (brine, #spodumene, salt-rich clays, etc). There's enough in #Nevada alone to convert every vehicle in the US to electric. Estimates for seawater extraction (enough for quadrillions of #EVs) have dropped from $25/kg a decade ago to $5/kg now. It's only not used because land resources are even cheaper. #Lithium is only 1-3% of a #battery anyway.

@TheExecutiveEditor This year, I've submitted a resolution to force the #Tesla board to draft and maintain a #KeyPersonRisk strategy to prepare for the possibility of his departure. Which isn't a very radical or confrontational approach to take - I could have gone directly for removing him - but I think strikes a balance. Hopefully #ElonMusk will back off and stop undercutting the company like he's been doing recently.
I will however help others submit other resolutions, of any variety.
-
@TheExecutiveEditor This wouldn't happen overnight. But over the course of years it would slowly rot the company from within. That's why, while I'm very positive on Tesla's status and future, I think it's important to decreasingly separate #ElonMusk from being the public face of #Tesla. #CTO is fine. But it's damaging to be seen as "The #Elon Company" when he's acting this way in public.
It's why I'm involved in #ShareholderActivism

@Timmy ... roof has great potential on new construction, I question its viability on retrofits, and the long scaleup opens up the path to competitors.
But what I think the market HEAVILY undervalues is #GridScaleStorage.
Right now, there is a quiet revolution going on in electricity grids: large battery facilities are killing the traditional grid services market, with far better economics - limited only by the extremely tight supply of grid-scale #batteries.

@Timmy In recent quarters #Tesla's two new factories - #GigaBerlin and #GigaAustin - have been holding back their margins. Because new factories always do - you have to amortize a lot of cost with low production. But as production scales, new factories turn from margin sinks to margin boosts. And this is happening with two factories simultaneously.
It's not all roses - Tesla's third major market is #China, and their economy is cratering right now. I expect more price stimulus there...
-
@Timmy On the #Europe front, there's a different but equally powerful story unfolding. Plagued by bureaucratic delays, #GigaBerlin is finally starting to accelerate production, and - key issue - production *local to Europe*. Which doesn't simply eliminate international shipping costs, but lets the company avoid an 8% tariff on imported cars. Which is an effective 8% reduction in COGS and 25% increase in margins. I don't think I need to describe how massive that is.

@riskable My focus is on the #EV space. But temperature matters there too, because #neodymium magnets start to lose field strength in the range of temperatures motors actually experience (~80°C). So you have to use higher amounts of #dysprosium, which means even higher cost & somewhat lower nominal field strengths. So #tetrataenite could be a really good fit, IF the achievable field strengths can approach the theoretical.
Need to watch this space, as I have investments in some rare earth plays.
-
Hey, any #researchers (#physics, #materials science, etc) doing #research on magnetic materials [#magnetism]? I'd like your take on the prospect of #tetrataenite as an alternative to #neodymium #magnets. My understanding is that the theoretical magnetic energy product is about 80% that of available neodymium magnets, but that raises the question of how much realizable magnetic energy products might approach theoretical.
