Battery based electric vehicles of today and tomorrow.

Yes. He has put the money in startups going for a 10x gain again I expect. It will be 10 years before Tesla is $10K per share. He has a Roth IRA containing $5 billion. It was kind of strange that it was a former CEO of Ford now at Hertz that said Tesla was the only one Mass producing EVS and was their only option to move to ev's.

I actually did sell some of my tesla stock at $740. and put it into a startup.....just not ALL of it. Diversification -- even in risky ventures!

I wonder what will renting EVs do to the batteries. My thinking is renters don't keep their cars for very long and to increase range, they might to always charge them to 100%, which unless they are LFP, is bad for the battery longevity. They will probably replace the vehicle before it becomes an issue for them but the buyer and warranty?

That Model 3 comes with LFP. If Hertz keeps them 3 years they could put them in a fleet of Robotaxis.

So far only the SR+ comes with LFP. Not sure if the SR+ will be the trim of choice though. If you look at the millage rented cars have after just six months, they are obviously not rented to go get the groceries, hence why LR would make more sense in my opinion.

I read that on average, rental car companies rarely keep their cars for even 2 full years. They either sell them back to the manufacturer as program cars, or sell them to used car wholesalers, or sell them directly as used cars.

I've never rented a car that wasn't for the current year model.

Tesla increases the price $5,000 for the S and X Models.

Tesla increases Model S and Model X prices by $5,000

Tesla has increased Model S and Model X prices by another $5,000 as demand is pushing deliveries of new orders...

Sounds about right on a $100K car and 5.9% inflation.

Sounds like Leo may have picked up a hundred million dollars today in Tesla profits.

TSLA --- here we go again..........!

Do you think there any short sellers covering still going or is the world just starting to realize the EV cost savings and yet Tesla is the only EV maker selling their vehicles at a profit?

 

[Gale Hawkins]

Why the next electric battery boom may be in cargo ships

The low tech low cost heavier batteries could work for ships.

 

[Gale Hawkins]

Dragonscale: a beautiful approach to solar

This looks cool.

Maybe Tesla will raise $100 billion in stock sales not only to build more EV factories but go full bore on solar and solar storage.

I just read an article that said enough batteries to move a 747 from NY to London would weigh some ridiculous amount. It then compared the power densities of hydrogen, jet fuel, batteries, etc... per pound.

Based on that, I don't think moving large objects like containers ships with batteries is going to be a viable option. The batteries would weigh more than the cargo and ship combined.

 

[Gale Hawkins]

Ships and jet planes may not be as comparable as you think.

Read the next to last subheading about smaller electric container ships deliver containers up the MS River for example. Batteries will be in cargo containers for fast swapping at ports.

Without power ships float but planes crash.

When we talk about ships we can return to the past, a lot of research on modern sails, automation etc so things happens.

I don't foresee batteries as the only source of lower pollution energy. I know some aerospace companies are looking into hydrogen and electric engines (or a combination thereof).
Fission and fusion power generation (fusion seems to be a fast coming technology reality).
Of course, wind and solar power, to a much lesser extent.
But until countries such as China and India (which account for some 25% of fossil fuel pollution) join in, there's little probability there'll be significant reduction in global warming

Yeah, the article was on a hydrogen fuels airplane. It was comparing the power that could be squeezed from each pound of fuel source. I wish I could find it again. It was just yesterday. Grrrrrr.... (at least I remember what I had for dinner last night).

This was the energy density chart I was looking at the other day.

Horizontal is mass.
Vertical is volume.

By weight or by volume, batteries can only store about 2-3% of the energy that aviation fuel can. Hydrogen can store way more energy than aviation fuel, but it takes up way more volume.

When operating large container ships, both weight and volume have to be considered.
