They're or you're doing variable pricing wrong if you're not already charging when the price is negative...

Wholesale prices are negative.

That is not passed down to the consumer level.

When PG&E is trying to shed excess power, they are still charging me the normal high daytime rate. I have no incentive to help them soak up the surplus.

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.

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.

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.
