Amprius’ new SiMaxx cells hit an impressive 360 Wh/kg in energy density – far beyond the USABC’s target of 275 Wh/kg. What does that mean for EV drivers? Simply put, longer range without a bulkier battery. Plus, these cells have a power density of 1200 W/kg, meaning more efficient energy delivery.

Neat! Glad to hear
Yeah they've done a good job with their documentation.
I was tempted by it several times already to try some features I didn't even consider using.

That's a weird comparison to make. The Aptera is smaller and uses different materials.
Afaik it's going to be classified as a motorcycle in many states in the USA, but they're still aiming for a high rating. I know they have crumple zones and a safety cell made from composites akin to F1 cars.
Whether what they're planning will be enough, we'll only know for sure once they test it.

The math works quite well as long as the information is accurate.
Of course things can always turn up to be different in the end product.
But from the information we have now, ~4 hours of good sunlight conditions will be enough for 43 miles.

The body weighs around 360kg, with a 60kwh battery it supposedly weighs around 800kg (the smallest and lightest option is 25kwh), with a drag coefficient of 0.13.
In comparison to some of the most efficient cars - the Hyundai Ioniq 6 is around 1,860kg with a drag coefficient of 0.21. Tesla Model 3 is around 1760kg with a drag coefficient of 0.219.

It's going to be a whole lot more efficient than the average car just based on these numbers.

Now it depends on how much of the car's surface will be covered by the solar panel and what's the panel's efficiency.

Or 43 miles in Aptera's case

Just update it to the latest

[–] ArtikBanana@lemmy.dbzer0.com 14 points 1 week ago

The first patched release is version 5.0.1, released 2 days ago.

Summer Eternal has Tuulik and Red Info has Rostov and Kurvitz

Just a rule of thumb for the future, don't use a DRAMless QLC SSD as an OS drive.
Or even just a QLC SSD.

Newmaxx has a spreadsheet with details and recommendations - https://borecraft.com/

I've also been thinking of getting the NM790. Just take into account it has no DRAM.

Yup.
Tailscale has some documentation about it, and also a bunch of examples (And apparently one specific to Immich).

 

PV = Photovoltaic

 

Firebrick systems powered by renewable energy could be used for up to 90% of industrial process heat applications, the Stanford study says. Meeting that demand in the U.S. would require firebrick system capacity of 2.6 TWh, with a peak discharge rate of 170 GW.

 

“But even in the only country that is massively building, China, nuclear development is comparatively marginal. In 2023, China started up one new nuclear reactor, that is plus 1 GW, and more than 200 GW of solar alone. Solar generated 40% more power than nuclear and all non-hydro renewables—mainly wind, solar, and biomass—generated four times as much as nuclear.”
The report also highlights how nuclear power is being challenged not only by the strong growth of solar and wind, but also by battery storage, whose costs are projected to decline below those of coal-fired and nuclear power plants by around 2025 in China. “Solar plus storage is already significantly lower than nuclear power in most markets today, as well as highly competitive with other low-emissions sources of electricity that are commercially available today,” it also notes.
The authors also cite data from investment bank Lazard revealing that solar-plus-storage can already be cheaper than gas peaking and new nuclear. “The competitive cost and large-scale availability of variable renewable energy sources combined with firming options—especially storage—could well turn out to be the game-changer of energy policy in the years to come,” they further explain.
