Hyundai announced they don't expect to release solid-state EVs until 2030, but their solid-state plant has been operational for a bit now and they're filing full-scale solid-state production patents already. It's going to be a real race to the finish.

Adam's ale (also referred to as Adam's wine, especially in Scotland; sometimes simply called Adam) is a colloquial allusion meaning water. It alludes to the idea that the biblical Adam had only water to drink. This inference gained popularity around the beginning of the 19th-century temperance movement.

You would need a lot of people actively involved to pull something like that off and the number of conspirators involved is inversely proportional to how long the conspiracy can be kept secret. So if it happened, the truth will come out in a fairly short time. Until then, I don’t see any point in entertaining these ideas or getting overwrought by them.

I'm sure Salman is elated.

Anytime an article posts shit like this but neglects to include the full context,

They link directly to the journal article in the third sentence and the full pdf is available right there. How is that not tantamount to including the full context?

The tax bill and the tariffs are separate. In sum there would be a $40M surplus each year for a decade.

Is it Doritos dust?

I’d rather read twenty minutes than watch a 5 minute YouTube video.

I don’t think I’ve ever encountered a video, YouTube or otherwise, that conveys information faster than an article. It’s usually 10 minutes of video to convey what would take 3 minutes to read while providing greater detail.

Inverters and solar battery storage generally have some combination of wired and wireless communication. You need to communicate with the grid for real-time pricing and forecasts so the system knows when to charge and discharge. Also you want the system status of all the panels and batteries. If somebody slices through the wrong fiber line near your site, it’s important to still be able to get that information.

If you get a home PV system, they’ll often have the option of a cellular modem. The controller on my home system has Wi-Fi and Ethernet with the option of a cellular modem. It wouldn’t surprise me if the board comes populated with some of the components necessary for cellular functionality even if you don’t opt for it.

I’m just saying they need to divulge more details before one can conclude this is nefarious.

Over the past nine months, undocumented communication devices, including cellular radios, have also been found in some batteries from multiple Chinese suppliers, one of them said.

The two people declined to name the Chinese manufacturers of the inverters and batteries with extra communication devices, nor say how many they had found in total.

They're very light on details. Sometimes it's cheaper to make one PCB in huge numbers and only enable the cellular modem on the higher priced models or when a subscription fee is paid. Their mere existence without any additional information shouldn't be particularly alarming.

Fronius is Austrian and there are a few others but none producing microinverters that I’m aware of. If you are doing an install with no shading issues during the day, regular inverters are preferable though since the costs are cheaper and there’s no DC-AC-DC loss if you include a battery backup.
