It is relatively easy to make a quick EV, but making a good one from the efficiency, charging, cost, and utility perspective is difficult. So their focus on power output has me concerned about the other aspects lacking…

Definitely had a chuckle at the G10 Max-Extreme prediction. 😆

Was pretty interesting seeing the Gen3 car they had in the fan area at some of the Formula E races last year with no rear brakes. They still had front brakes (article states otherwise, not sure if they meant rear or if there was some later change I am not aware of).

At any rate, definitely exciting to see the performance levels starting to eclipse the combustion counterparts while being lower cost.

That site is something special… Basically lobbying against renewable energy, promoting “the hydraulic fracturing revolution”, and stating how bad an Obama policy was in nearly every article.

Appreciate the link, I didn’t see the website was in a repository. I opened an issue.

Looks interesting but I am curious about their ‘Community Survey’ results, this line in particular:

From this we can see that the majority is currently running on Windows (47 users across the various versions), followed by Linux users across a few different distros (57 users across Mint(9), Ubuntu(13), Fedora (3), Debian(13), FlatPak(5), Mageia(1), Slackware(2), Arch(9), Gentoo (1), PCLinuxOS (1)).

I am not a mathematician or anything, so quite possible I missed something, but wouldn’t the 57 Linux users be the majority?

Impressive for sure, but curious how this Guinness World Record is different from the 749 mile (1205 km) one Lucid set in June?

Edit: Looks like the Polestar record is for “longest journey travelled by an electric SUV on a single charge” while Lucid was for “longest journey by an electric car on a single charge”.

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.

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.

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.

Interesting to see how much of a difference the study showed between vegetarians and non-vegetarians taking the same supplements and performing the same workout routine. Vegetarians had a gain of 2.4kg of lean muscle mass while the non-vegetarians had a gain of 1.9kg of lean muscle mass. That is a substantial difference, will be quite curious if similar results are replicated in further studies.

Still, the conclusion is that people on a vegan diet are not deficient in creatine but some extra (3-5 grams/day) could be beneficial in boosting memory later in life and help with muscle development/fatigue.

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.
