Interesting technology but the article compares the bare motor at 28.8 pounds (13.1 kilograms) to a complete Tesla Model 3 drive unit at 176 lbs (80 kg) which has not only the motor but also inverter, oiling system, gear reduction, differential, etc...

A better comparison would be something like Lucid Air motor which they give weights for the core rotor and stator assembly of 69 pounds (31.4 kg) and power density of 15.6 kW/kg, compared to this prototype motor at 42 kW/kg.

That is very generous of you to offer. Sadly, I am not in the EU, otherwise I would certainly take you up on it.

I've started working to source the hardware components and it definitely seems to be tricky to find some items at a reasonable price or at all. You'll probably see me on the forums soon also trying to verify if I have suitable substitutes.

Appreciate the extra insight. Any sources you recommend if someone is trying to avoid news sources that are corporate biased or propaganda outlets?

Other large outlets not on the list like BBC, The Guardian, Al Jazeera, RT, all seem like they would fall into one or the other of those categories to varying degrees. Visibility on quality, unbiased, sources of news is certainly needed now more than ever.

Thanks for sharing this! I've been passively following the flow battery tech for a while but had not ran across this project before.

Quite interested to see if I can get the experimental version working to some capacity. Hopefully the chemicals are not too difficult to purchase in small quantities.

I am quite curious to know what news sources you consider to not be "corporate-neolibral brained" if NPR, The Associated Press, Newsmax, and Fox News are all the same in your book?

Maybe I just misunderstood the point you were going for and need some clarification.

This will be another hurdle for electrification of all types as it will make less economic sense for the average home with substantial electricity price increases while fossil fuels prices are kept artificially low. The only silver lining is it might make solar/battery storage more attractive to have less reliance on the high priced grid electricity for those that can afford the upfront investments.

Electric vehicles will be especially hit since you already have fast chargers like GM Energy charging 0.55-0.60c/kWh which ends up being more expensive than driving a ICE vehicle getting 20-25mpg at the current prices.

Ah the Yamhilll Pub, the graffiti continues on the inside as well.

And to think, we haven't even reached the hotter months of July and August in the boreal summer yet.

At least this looking like a neutral period for the ENSO so maybe we won't break as many records this year.

It certainly can vary quite a bit as the graphs in the article show. Seems that cell chemistry, thermal management, and total cycles are the largest drivers of degradation. EV's with generally smaller, more frequently cycled packs, no active thermal management, and cell chemistry not optimized for that use case will not fare well in hot climates. Something with a larger liquid cooled pack, that doesn't experience as many cycles, will fare much better regardless of the chemistry and easily still have useful amounts of capacity after 20 years.

As a data point, this is from an early 2016 EV with 90,000 miles, roughly 50% DCFS, and about half of its life in a temperate climate. Nearing 10 years and just under 3% degradation.

The phrase I have in repeat in my head after hearing it several years ago is, "This will be the coolest summer of the rest of your life.". A stark reminder of the collective action and adaptation needed.
