True but his point is valid, batteries (kW/kg) and charging from dirty generated energy at this moment makes no sense. Generating clean energy has been a problem for the last decades just as the battery efficiency increase has not been what was promised/expected.
This really should be done before everybody is allowed (yes the correct word) to buy an EV or the western countries energy system would be worse than in Afrika.
Elon Musk reminds me a lot of Nikola Tesla. Early in both of their lives they made a lot of money. Both were showmen and liked to make huge enormous claims. Both have had huge failures and huge successes. Neither took a physics class or understood the laws of thermodynamics.

Really? I will stand corrected. In a book written about him it says he left Australia for Canada when he was 17-18 only to find the relatives he was supposed to be staying with left for Australia on an extended vacation. He had something like $500 to his name. Guess I missed the part about him attending college.
I will assume he attended an accredited college and didn't just purchase his degree or receive and honorary degree.
Thanks for correcting me.
After two years at Queen's University, Musk transferred to the University of Pennsylvania. He took on two majors, but his time there wasn’t all work and no play. With a fellow student, he bought a 10-bedroom fraternity house, which they used as an ad hoc nightclub.
Musk graduated with a Bachelor of Science in Physics, as well as a Bachelor of Arts in Economics from the Wharton School. The two majors speak to the direction Musk’s career would take later, but it was physics that made the deepest impression on his thinking.
“(Physics is) a good framework for thinking,” he’d later say. “Boil things down to their fundamental truths and reason up from there.”
Musk was 24 years old when he moved to California to pursue a PhD in applied physics at Stanford University. With the internet exploding and Silicon Valley booming, Musk had entrepreneurial visions dancing in his head. He left the PhD program after just two days.

If solar ... were to provide 33% of the worlds electrical needs it would take all the Aluminum ever mined
Let’s say we could make solar panels which would convert nearly all the suns energy to electricity. If we did that there would be no energy for plants to grow and we would be in the dark even at noon. Think about it.

Having done some really rough math for the amount of steel cable you need to store a TWh or so of energy with ocean gravity storage, it seems doable to me. Uses less steel than changing the US electricity generation to nuclear.

Let me in part answer that. I worked at Lawrence Berkeley National Laboratory where they developed a new type of solar panel which would capture additional wave lengths of light and thus produce more electricity for a much lower cost.
That was about 10 years ago. Where these inexpensive 500 watt $200 panels? Well we could have them. But’s it’s the Osborne Efect. Company’s have sent millions to create factories to produce the current 300 watt solar panels. Can’t exactly have new solar panel company go into business and produce pannels at lower price before the existing factories are paid off.

So wher’s the development? And where are the products?

I don't think it matters. No need to prevent everyone from buying EVs because already not everyone is going to buy them, 10 years from now I expect the ICE to still be dominant while EVs will be a great fit for a portion of the population. If it gets to where the utilities are having trouble supplying the demand, the incentives will vanish and that will help to limit EV adoption. In areas where I live that have a lot of hydroelectric power with surplus capacity at night a certain number of EVs are ideal for leveling the demand since most people, at least the EV owners I know plug them in to charge each night when they get home.
Last year I purchased a pallet of 27, 285 watt Grade A panels for 24 cents/ watt (i.e $68.40 per panel). Prices go up and down but you can currently get panels for about 40 cents/watt. See HERE

Okay I don't get it. The 250 - 325 panels I've been seeing run about $300 - $350. Or about 4 times what you purchased yours for. How is it this company is selling panels so inexpensively?
This thread has several times shown disdain for solar/electric/renewable technology with comments that none of these things are new, and that they were dropped before for good reason. And therefore should remain off the table.
The ideas are not new, but new developments definitely change the equation. A simple example shows how. Battery powered lights for closets and other areas which are not mains wired have been around for my entire life, and probably much longer. I would guess they were first introduced in the 1920s or 1930s. And have never made a market splash because the low light output and high battery consumption made them uninteresting to all but the most motivated purchasers. But with the advent of high efficiency LEDs and with a modest contribution from improved battery technology (not Lithium, just long life alkali cells) these things have actually become useful. They still won't eliminate mains wiring, but they make real sense in low usage situations like closets and remote corners of storage areas and shops. The batteries have changed with higher capacity and much lower self discharge rates, and the LEDs cut power consumption by at least an order of magnitude.
The biggest problems these things have now is the marketing hangover from the horrible performance of older versions of the product. Which is true about at least some of the technologies discussed in this thread.

Cult: a system of religious veneration and devotion directed toward a particular figure or object.
Religion: a system of faith or worship so it's broader than that.
Faith: pretending to know something you don't know.
Incorporating these two definitions a cult becomes, a group of people whose enthusiastic devotion to something is built on a foundation on them pretending to know something that they don't know.
