OK, that makes much more sense. I had previously seen flywheels mooted as a solution for powering cars. The notion of a hundred kWh of flywheel energy skipping down the street was kind of horrifying. Stationary flywheel batteries make all the sense in the world.

The precession as you go around corners or over hills would make the handling characteristics almost unmanageable I think.

Not sure which part suggests they are not dependable. If you mean "fires per capita", it can only go down as the years go by. And if it does happen, it's for one unit, not all of them. Here's a test from 2016.

It's not the dangers of Li-Ion batteries but the fact that lithium is so expensive and also needs nickel & cobalt, all of which are scarce & expensive, let alone the environmental costs. Li-Ion batteries are great for EVs (until something better comes along) but IMHO grid storage, since stationary, can be big. Like reflow batteries. Lots of new developments coming down the pike. :)

Oh, well lithium has become expensive because demand now outweighs supply, which I see as a very good thing. Cobalt isn't really necessary. I think Chinese Teslas don't use cobalt and neither do grid batteries (LPF chemistry). Cobalt is used to extend range and performance for more demanding customers (or companies, or models offering better specs). Lithium and cobalt mining have no where near the impact of iron, aluminum, copper, lead, and many other resources, so I can't take lithium and cobalt critics seriously. When they pinpoint batteries and ignore everything else, I get sleepy. (I know you're not a critic - I'm just saying be to keep being careful.)

There might have been large economic shifts in the past, but this is the one I get to witness "live".

A table comparing tractor truck specs. Some numbers are openly estimated until they can be verified, but I would expect them to be updated as they find the data.

That’s an interesting table. Yesterday I watched Transport Evolved’s take on the Hummer EV, and one thing that they went on about at some length (and probably rightly so) was how inefficient it was at 1.2-1.3 miles/kwh, which makes it worse than all but one of the Freightliners on that chart.

Hmm, I would be interested in specifics like towing range, recharge times, and load specs. That's just an ad.

If range scales with MPG figure about 1/3 range loss towing an average camper.

I think everyone else is also waiting. That was just a first reveal. It seems to be a big thing for carmakers to pick the right specs, the right time to reveal them, and the right way, as it can all affect demand and sales.

Germany just passed the halfway mark in EV sales.

The split down here would be interesting to see. Car purchase figures for 2022 were just released last week and over 75% were "commercial vehicles". That's things like SUVs, pickups, vans, etc. We used to have the second-highest per-capita rate of 4WD ownership in the world, with Saudi Arabia at number one. Not sure where we are now, but I suspect higher per-capita.

"Demand for electric vehicles (EVs) in Australia has grown again, with the EV market share increasing by 65% in 2022 to 3.39% of new light vehicle (car) sales."

Thanks. I'm just trying to get a handle on what the charging support costs might be. I've ready wildly differing numbers, so I figured I'd ask you folks that actually made the investment.

A friend of mine bought a 2022 Bolt EUV. He lives about 100 miles from me. ( I live on an old dairy farm in NW Wisconsin. ) I have a 220v 50a welder plug in my garage so he picked up a 4 prong 220v 50a receptacle and came down and we installed it. Now when he comes down to visit or help do something he just parks by the garage and plugs in the Bolt. In a few hours he's all charged up to head back home. The receptacle cost around $15.
 
I wouldn’t put much stock in the Wyoming thing until it passes one house of the legislature. You can get a group of lawmakers to propose nearly any damn thing.

BERLIN—Electric-vehicle sales crossed a global milestone last year, achieving around 10% market share for the first time, driven mainly by strong growth in China and Europe, according to fresh data and estimates.

While EVs still make up a fraction of car sales in the U.S., their share of the total market is becoming substantial in Europe and China, and they are increasingly influencing the fortunes of the car market there as the technology goes mainstream. The surge in EV sales also contrasted with the broader car market that suffered from economic worries, inflation and production disruptions.

Global sales of fully electric vehicles totaled around 7.8 million units, an increase of as much as 68% from the previous year, according to preliminary research from LMC Automotive and EV-Volumes.com, research groups that track automotive sales.

Ralf Brandstätter, the head of Volkswagen AG’s China business, told reporters on Friday that electric vehicles would continue expanding fast and that China could soon reach a point where sales of conventional vehicles begin to permanently decline as plug-in vehicles take bigger market share.

“Last year, every fourth vehicle we sold in China was a plug-in, and this year it will be every third auto,” Mr. Brandstätter said. “We haven’t reached the tipping point yet, but we’re expecting to get there between 2025 and 2030.”

For the full year, fully electric vehicles accounted for 11% of total car sales in Europe and 19% in China, according to LMC Automotive. Combined with plug-in hybrid vehicles, which can be plugged in to recharge the battery but also have a small combustion engine, the share of electric vehicles sold in Europe rose to 20.3% of the total last year, according to EV-Volumes.com.

The U.S. lags behind China and Europe in the rollout of EVs, but last year auto makers sold 807,180 fully electric vehicles in the U.S., a rise in the share of all-electric vehicles to 5.8% of all vehicles sold from 3.2% the year before. Tesla is still the world’s dominant EV maker, but conventional auto makers are shortening its lead with new electric-model launches.

In Germany, the largest auto market in Europe, electric vehicles accounted for 25% of new vehicle production last year, according to VDA, the German automotive manufacturers association. In December, there were more EVs sold in the country than conventional cars.

New-car sales overall fell around 1% to 80.6 million vehicles, according to the LMC data, with nearly 4% growth in China helping to offset a decline of 8% in the U.S. and 7% in Europe, which was hit by the weakening global economy, soaring energy costs, supply-chain disruptions and the war in Ukraine.

Bayerische Motoren Werke AG, the German luxury-car maker, was one of many manufacturers last year to see sales of plug-in models rise even as overall sales tumbled. BMW reported a 5% decline in total new-car sales but saw EV sales more than double last year.

“We are confident that we can repeat this success next year, because we have a continued high order backlog for fully electric models,” BMW sales chief Pieter Nota, said this month, commenting on the growth in sales of electric models.

VW, Europe’s biggest manufacturer by sales, said on Thursday that overall new-car sales fell 7% to 8.3 million vehicles last year, but sales of electric vehicles rose 26% to 572,100 units. The sales figures encompass the company’s large stable of brands, including VW, sports-car maker Porsche, luxury-car brand Audi and passenger-car brands Skoda and Seat.

I don't know if this has been posted before, but this looks like a pretty cool project using iron redox flow battery technology on a grid scale. The battery farm will eventually run out to around 2 GWh. To me, the iron redox chemistry is very cool since it primarily uses iron, chlorine, and potassium (no doubt there's some secret sauce too), all of which are fairly readily available. In a win-win for Sacramento, the manufacturer is setting up a factory in town to produce the batteries for this contract, leading to some nice economic development down the road too.
