You need a lot of batteries to store the energy needed overnight and you have to plan for (lots of) days without sun. At my latitude (45N) the difference in solar production between summer and winter is 5x. Even with batteries, you still need a backup for a week of bad weather; so you have to choose between increasing the solar production 20x to have enough power generated in cloudy days or have a backup coal/gas/something else plant.

It's global data, "here" is not US, and it's solar+wind, not only solar. Summer months have a different definition depending on hemisphere and solar production maximums depend heavily on latitude.

One thing to note: These Xeons have quad memory channels, that usually means double the bandwidth of an equivalent desktop CPU, if you populate all the slots.

I have a dual E5-2667 v2 server with 512GB DDR3 and it's quite nice, the memory bandwidth is higher than of a DDR4 desktop with a way newer CPU, even though it's ECC and registered.

Not really. They use aluminum fins because they are way lighter and cheaper. The copper tubes are actually heat pipes that transfer the heat through liquid/vapor phase change. And copper is used because the liquid inside is water (aluminum would corrode) and they are also easier to bend into shape (aluminum fatigues easier with bends, and pores would allow the liquid to escape).

In the energy results they are comparing their novel water block cold plate against an air cooled facility, not against a similar water-cooled facility.

There are "simple" hardware tokens that allow for that - you have to enter the amount and part of the destination IBAN and they generate a 2FA number based on that + probably the same number generator it uses for logins.

ADSB is not mandatory in the US below FL100 or FL180 (10000/18000 feet), that covers most helicopter flights.

It depends also on the website you are using to track. I have an ADSB receiver that publishes to multiple tracking websites (the same data, unfiltered), and not all of them publish all the data. Flightradar24 doesn't show most of the military aircraft - I can see them on my local tracking interface but they are not shown on their website.

Also, batteries will degrade faster over time when they start to degrade, because they need more frequent charging. Their internal resistance increase and that promotes heat buildup during fast charging/discharging, another thing that promotes degradation. Slow charge/discharge cycles also help with heat management.

Then you will have a problem if you want to filter the entries. You will need a good parser to identify that "Paris" means the capital of France or one of the many in the USA[1].
