They say they can predict earthquakes between 20 days and 30 days before they occur.

Two possible scenarios I can think of:

1) They issued the warning after analyzing the data from within the time window.
2) The statement "between 20 days and 30 days before they occur" may really mean "as far out as 20 to 30 days before they occur."

Actually the studios axed DiVX. The agreements were for so many movies per year, and as the studios didn't want to hurt DVD sales or their own (nonexistent) streaming services, they began to provide movies like "I'm Gonna Git You Sucker", I kid you not. The DiVX platform was way ahead of its time - it was a tiny embedded JVM on its own processor that had a standard interface for the DVD player system to interact with. The same hardware ran on every single DiVX player - write (and build) once, run anywhere.

Supposedly the concept of the 'jar' file was a direct result of DiVX research.

It was a really cool idea - I could buy a disk from 7-11, toss it on the shelf, and watch it when I wanted to - no timeout on the first viewing. You could watch it as many times as you wanted to within 48 hours of the initial viewing, and be charged a buck or two thereafter (including on someone else's device). Each disk was individually serialized, so the backend always knew which disk had already been played.

I hope these monsters are UL-listed and won't jack up my homeowner's insurance because they're a fire risk.

At 10 kW * hr, I wonder what size inverter they supply? My house has a 20 kW generator and that will run everything, including the 2 AC units (mostly startup current). If their inverter is the same size, that battery will last _maybe_ 3-4 hours in the summertime.

I'd love to don an airtight suit and try to walk/crawl on that river.

According to these documents, I'd displace .0092 m^3 (9195 cm^3) of mercury (yes, I weigh in at nearly 125 kg).

By using the largest values for foot, calf, and thigh volumes, the second document tells me that I could stand up in the mercury, and that it would come up 15% of the length of my thighs or so.

Assuming I'm vaguely rectangular when I'm supine (41 cm wide by 183 cm tall), I'd float in 1.2 cm of mercury.

We have at least one instance of that in the US - Excedrin. Their "Extra Strength" formulation has the exact same amounts of the active ingredients as their "Excedrin Migraine" and "Excedrin Menstrual Complete". At least at Walgreens Online they charge $17.99 for 200 Extra Strength caplets and $18.49 for 200 Migraine caplets. In the actual brick-and-mortar stores the prices are usually identical. Walmart's prices are the same.
