For those of us with Teslas and Lucids, the Tesla Universal Wall Charger is a great choice. Mine works flawlessly and handles scheduled charging well. I schedule charging from 9:00 to 2:00, to take advantage of excess output from my solar array...

As a pilot, I disagree. For a person under stress and under the influence of alcohol, 60 seconds is no time at all.

Logged out and logged back in... it worked!

Good point, I hadn't considered that!

I did exactly the same thing. Going old school is much more convenient.

True. It's also possible to borrow shares and not sell them. A borrower may want to vote them, for example. Mostly false. It's not possible to "disrupt the supply of real shares". Borrowing shares doesn't create more shares, nor does selling short. The number of outstanding shares remains...

Goodhart's Law: "When a measure becomes a target, it ceases to be a good measure." This applies to EPA mileage tests: manufacturers configure their cars to perform well on the tests. Performing well in the real world is a different problem.

For those of you who own LCID, you may wish to lend out your shares. Lately, the rate has been about 9%. Of course, there are arguments against lending, but on balance I decided it was worth it.

I'm glad someone finally made this point: that the power required is proportional to V³, not V². Thank you!

Here in Massachusetts, I installed a rooftop 18kw array about 4 years ago, along with three Powerwalls. There's no way it would have made economic sense without the massive 30% tax credit from the Feds and the state, and the ongoing subsidy from the utility. Not even close. The utility...

I have the newish Tesla Universal Wall Connector on a 60-amp breaker. I use it to charge my Model S and my Air Touring. Works well. https://shop.tesla.com/product/universal-wall-connector
