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

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).
