Mid-afternoon charging is only practical if you work from home.
That's millions of people.
Or use charging at your employer
Lots of people do that too.

If you invest in a mining rig, will you want to leave it idle 98% of the time?
Same for an osmotic purifier. They are expensive and need steady baseload power to be cost-effective.
Neither is effective as demand peakers.
Hydrogen generators are cheap and can suck up a lot of power, but you need to store the H2 and find a market for it.
They should just install more batteries.
Batteries are not currently cost-effective.
We need sodium batteries for grid storage.
When I stop hearing about brown outs due to excessive AC use then I'll believe it.
RTFA. The brownouts are in the summer. The excess solar is in the spring.
So what do you do after the sun goes down?
Wind turbines, hydro, stored energy, gas, and nuclear (Diablo Canyon recently received a 5-year license extension).
We could also use that cheap electricity to desalinate water or train AI models.
Desalination plants are expensive. It's silly to build one and then only run it for 50 hours per year when energy prices go negative. You wanna run it 24/7, but then it's baseload and contributes nothing to solving the surplus energy problem.
AI data centers are even more expensive. They need clean, reliable baseload power.
Adding more solar is good. We need more.
TFA talks about prices going negative, but that happened 21 days last Spring and only for one or two hours. 98% of the time, it isn't a problem.
There are many solutions:
1. Storage: Pumped hydro and/or peaker batteries.
2. Long-distance HVDC to sell the surplus to other states.
3. Variable pricing. I currently charge my EV from 2-4 AM, when prices are lowest. I'm happy to switch to mid-afternoon charging if PG&E gives me an incentive.
Median income numbers mean nothing as the inflation calculations have changed
Most economists believe that inflation is over-estimated, so median incomes have actually risen even more that the official figures.
all the hyper processed stuff that is called 'food' now.
Poor food choices are a completely different topic.
There's plenty of quality food if you want to buy it, and it's cheaper as well. Potatoes cost less than potato chips, carrots cost less than candy, and water is cheaper than soda.
The healthiest food is available in the neighborhoods with plenty of immigrants.
In other news, you're more likely to receive a longer prison sentence if the judge hasn't had lunch yet.
I don't think I graded in alphabetical order, just the order of the stack of work to look at.
So the assignments on the top of the stack, which were the last to be turned in, received the lowest grades.
That doesn't seem totally unfair.
AI usually makes bias worse.
AI makes artificial bias worse because it has less real bias.
For instance, an AI system used in New York recommended that more blacks than whites be denied bail.
That is artificial bias because blacks are less likely to show up for trial, so if that's the criteria, it isn't "real" bias to deny bail to more of them. It might not be "fair" or the right thing to do, but it isn't "bias". It's a recognition of reality.
since they won't be able to get jobs.
The workforce participation rate of immigrants is significantly higher than for the native born.
If you look at how poor more than half the country has become
Real median incomes have increased significantly since 1970.
food wasn't as expensive.
The best measure of food cost is the hours of earnings needed to afford it. The price of food has declined since 1970.
Mitigating climate change is for human civilization defense.
How does this mitigate climate change?
The major input is electricity from the grid.
Singapore generates 92% of its electricity from natural gas and 4% from diesel.
Nothing in TFA indicates this scheme is breakeven or better on CO2 emissions.
Microsoft donates mostly to Democrats.
The big exception (and biggest single recipient) is Republican Doug Burgum for governor of North Dakota.
For God's sake, stop researching for a while and begin to think!
