Don-old - that's amazing. I am never disappointed with Lemmy's memes of the Big Orange Liar

*cognitive dissonance, but I totally agree. How does the far right insulate themselves in such non-realities
Thank you for continuing this history that the US education system never taught me.
AND VOTE EARLY!!!!!
Think of Tuesday, November 5th is the LAST day to vote. Some states start early voting up to 3 weeks ahead of election day!
EE here. Chargers put out power in units of kW, while batteries store energy in units of kWh or MJ or what have you. Otherwise, you're absolutely correct.
Typically Distributed Generation (DG) scale solar PV and battery storage sites are sized anywhere from 1 to 10 MW.
At 1 MW, you could run (1) charger at a speed of 1 MW, or (2) at 500 kW, etc. Usually need just (1) transformer for that size installation too.
At 10 MW, you can run each charger at 1 MW or so, but you're also talking about probably (4-10) transformers @ $250k USD a pop. Installation prices go up the more you demand in power transfer.
Then you need to consider that most DG projects need to pay for the upgrades to their downstream grid architecture, meaning reconducting or upsizing cable, breakers, switches, transformers, reactors, sensors, relays, etc.
Not saying it's impossible. You could co-locate and DC-couple solar PV or Wind parks next to charging points to get around some of the grid upgrades, but most people live in areas that require homes and grocery stores and other buildings than flat land meant for solar PV or Wind.
When it comes down to it, it's so much easier to just trickle charge your EV at night via arbitrage and when you're sleeping so all of this infrastructure doesn't have to been upgraded - and I'd argue upgraded needlessly because we need to save that copper and iron and materials for upgrades to the parts of the grid meant to interconnect renewables.
But there is no silver bullet to these things so we'll likely see more, larger chargers come through unless regulators stop it from happening.
Take my upvote...
I highly doubt Kamala will want to pull a sitting Democratic senator away from the 50/50 Senate given the elections coming up.
I think there is a greater chance that she picks one of the governors. My pick is J.B. Pritzker.
Unfortunately I think casting away Kamala as the pick would do more harm than good. She is the likely candidate. Joe can even make the transition smooth by entrusting the rest of his legacy with her, which is the reason he chose her as a VP in the first place.
People also know the name Kamala Harris, and they've known it for years now. It'll be a huge turn to bring in a new candidate on top and do all of the rallying needed to get votes.
I think Kamala's success will spend on the VP choice, her administration, and her campaign team more than her herself.
Mark Kelly as Kamala's VP? Having that balance of ethnicity would help her get the votes. It's exactly why Obama picked Biden
I'm a zoomer, and I have to say I prefer the current logo. The others just don't look clean. Big black borders, nah
Michael Thackeray filed a patent under Argonne National Laboratory for the leading EV battery chemistry worldwide today, Lithium Nickel-Manganese-Cobalt Oxide (NMC), sometime around 2007-2008.
The first cars with that specific technology started coming out in the US market in 2013/2014 IIRC, with EVs coming out before then basing their battery chemistry on NCA (Tesla) or LMO (Nissan Leaf & Chevy Volt).
That's a 5-7 year timeframe from laboratory to mass production.
If you consider new technologies today like Samsung's battery in this article, and make the not so unrealistic leap that we're better at battery production today than in 2013/2014, it's very possible that we see this technology hit the market in 5 years or less.
Technology always improves. It's CAPEX that hinders it, and I'm willing to bet that there are financial interests out there to keep the main battery chemistry NMC and secure steady profits.
