This is what happens when you blindly accept what a computer tells you.

To be fair, before the era of computer maps or smart phones I once did something similar (but not as serious) in the Colorado Rockies. Looking at a paper trail map, I convinced my wife that we could hike up to a lake, have a picnic, and hike back down. After getting a little over half way up, we decided to just stop, eat, and hike back. The sun set well before we got back, we didn't have flashlights, and we could hear coyotes (and maybe wolves?) and other critters, and for about a half hour could barely see our way by the little moonlight filtering through the forest trees. But we made it back, no problem, except for the admonishments from my wife.

Also, a standard US outlet is 15A @ 120V = 1.8 kW, not 1 kW. There's a little loss so you get more like 1.7 kW into the battery.

A circuit is typically only allowed to be continuously loaded to about 80% by code, so you'd be getting about 12A or 1.44 kW into your car.

Also, 20A/120V circuits are quite common, most of my breakers are 20A.
Further, most houses also have 240V available. If / when I get an electric car, I'd have a 240V receptacle installed, which would be easy for me, since the panel is in my garage.

Officially, perhaps, but ABC is fighting tooth and nail to claim it is a "bona fide news program" [bloomberg.com] to maintain the exemption from equal-time regulations.

This whole thing is ironic, since it has been the Republicans that have done the most to push back against equal time rules since at least the Reagan administration, including interpreting the rule in such a way that news shows, talk shows, and entertainment shows could feature politicians without the need for providing "equal time".

I told you guys that whole Bernoulli thing was total BS ..

Well, it is true that the wing attack angle generates 2-3x more lift, than a cambered wing at 0 degrees. So while both the attack angle and camber contribute to lift, the attack angle is far more significant.

But the lift from camber and from angle of attack are both caused by the Bernoulli effect.

If we interpret the digits as base 10, we are only using 6 out of 10 possible digits. We have gaps in the range. That doesn't seem random. Some values having a zero probability of appearance.

You don't interpret the number of dots on the dice faces as digits in base 10, you convert the dot patterns to whatever base you want.

This is probably to compete with Halon gas in data centers, where you can't use sprinklers at all . . .

I've worked on many small data centers / server rooms ranging from 5,000 to 200,000 square feet, designing HVAC and plumbing mostly, but also a little fire protection, and all of them had pre-action sprinkler systems, as back-up to gaseous fire suppression systems or as the only fire suppression system. Water-based sprinkler systems were often required by codes, including, surprisingly to me, in an emergency generator building that housed six 3 Megawatt diesel generators operating at 4160 Volts originally designed with a CO2 fire suppression system. (just have to hope not being in that space when the sprinklers go off if the generators are running)

Technically you a right (the best kind of right) as a halon system won't push out all the oxygen (it can theoretically operate effectively at concentrations of less than 10% of the air), but it will displace some air, does interfere with respiration, and is heavier than air so it can pool in the breathing zone and suffocate you. (It can also cause frostbite from it's expansion from a liquid in the tank to a gas coming out of the nozzles.)
And Halon is no longer used because of its' ozone-depleting characteristics, but its' replacements have similar issues.

And you probably paid two million for a house because you lived in one of the big cities

LOL. When I did live in the big city, I lived in a house that I bought for about $54,000 in the early '80s (with a 12.125% interest rate) and went for about $175,000 when I moved out in 1999. I now live in an sort of mixed exburban / small town / farmland area about a 55 mile train ride to the big city downtown, in a house probably worth about $350,000 now.
And, yes, when I was a kid, back in the '60s, the big city air was pretty bad. But, thanks to the establishment of the EPA under Nixon, not so much now. Too bad the Republicans are currently trying to reverse a lot of the anti-pollution laws that Republicans had a big hand in creating

I can guarantee you that is not realistic to go to an office daily using anything other than a car in North America.

To the contrary, I had a 43 year career in North America making my daily commute by subway, elevated train, and commuter railroad. (though I did have to occasionally drive or fly to remote jobsites)
