@LargePenis@hexbear.net with a full roundup as well as a summary of results of Iraqi elections, building on his post about Iraqi electoral parties last week
@MarmiteLover123@hexbear.net, @Torenico@hexbear.net @darkcalling@hexbear.net in a subthread about the strength of the American naval buildup versus Venezuelan defences
DM me to highlight good posts in the newsmega and newscomm
I listened to a professional seminar about battery materials earlier. The speaker was legit but for dox reasons I won't name them. Here is a roundup of their points:
While there are lots of battery formula and also lots of niche applications, lithium iron/manganese phosphate is the main battery technology to beat for either stationary batteries or EVs. android robots like that Unitree one will probably be higher density formula with lots of nickel.
No one outside of China is doing commercially useful work on batteries. Companies/researchers in the west are either too silo'd and aren't integrated with the big picture, or their value proposition is predicated on LFMP batteries being more expensive than they have proven to be
They expressed general concern about the ability of the US power grid to keep up with projections of datacenter build out, discussed renewables+batteries as the only power generation technology that could potentially meet demand. To them, nuclear is a waste of time owing to long permitting times/very high costs.
Western EPCM firms get an 'F-' grade from him for project delivery, often having price tags 5-7x more than advertised. This applies to Western implementation of Chinese technology too, so just importing Chinese technology/talent is a fix for this issue.
Recent total installed cost (not just cells) of a grid scale stationary storage battery by a Chinese firm operating in Saudi Arabia was ~$75/kWh. Even a year ago I saw estimates more like 2-4x that.
There are no rare earths/critical minerals in batteries, but lithium supply can be a bottleneck and should be considered a strategic mineral. There are plenty of rare earths used in other car parts, just not the batteries.
China EVs are great quality, with 1000+km range batteries that charge in minutes in nice cars widely available. If exposed to Chinese EVs via free trade, vehicle manufacturers in the rest of the world would be 'decimated'
Some definite malding from the crowd about China being so obviously good and ahead of the pack compared to anywhere in the West, so that was fun too.
