All the rest of the complications and expenses remain, making it impractical for a single family home even with a time-of-day rates break.

This could, in principle, be easily solved-- air conditioners could easily store coolness. Water has a high heat capacity, and you could cool water during the solar peak, and use it to cool your living area in the afternoon.
Water storage is very inefficient in terms of weight and volume. Ice storage is better, since the heat of fusion is much greater than the heat capacity for a reasonable temperature difference, so I've seen ice storage used in a few large projects. Still a typical house has maybe a 3-Ton A/C unit, which is the equivalent heat removal rate of melting 3 tons of ice per day. Since you don't typically need full cooling all day, say storage of 1.5 ton of ice overnight, melting it during the day to supplement 1.5 ton of dx A/C at peak (actual numbers will undoubtedly be different). A ton and a half of ice requires hefty support, takes up about 52 cu ft of space, the tank & equipment to freeze and melt it efficiently takes up space and has significant cost, and the refrigeration cycle is less efficient since the evaporator has to get down to well below freezing while air evaporator coils operate around 45F, you have a lot of extra water piping and coils, and you still need a 3-ton refrigeration system but with more piping and controls It's probably not cost effective even if you're paying time-of-day rates.

I believe it was the OG Socrates who first started bitching about the ignorance of youth.
Actual Socrates loved the youth (wink, wink).
In the end, Socrates was executed for corrupting youth - the allegations being that he taught the youth to be anti-religious and not properly respecting the state's gods.

Copyright originally came about as a response to the invention of the printing press, and the subsequent publishing (for sale) of books without compensation to the authors.
The "right" to copy, print, and sell particular books was originally granted by the government to the publishers, not the authors.

Need to switch to pedestrian mode.
I had the opposite problem once. Wondered why the GPS kept saying "turn here" after I was already in the intersection. And then it tried to send me the wrong way down a 1-way street! Finally figured out it had somehow been switched to walking mode.

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".

This would be a good time to point out that every political argument has two sides and two points of view.
In my experience, very few political arguments are limited to only two sides and only two points of view.

Who said it was a newscast? It's named "The View", which basically states that it is opinion. Last time I checked, opinion is protected free speech.

Carpenters work with metal studs, too, not that there are many of them in an open data center floor.
