Maybe the air in Seaworld locations (such as San Diego) is not as good as somewhere in the north pacific ocean.

If you read my initial comment, you'll find the words "... the technology is actually there and ready".
Nobody is arguing about a technological problem.

I do not believe the Aldi - Wallmart comparison is fair. And having lived over 30 years in Canada, I can confirm that there you also find BMW under carports. Not quite as much as here, but a lot...

For the reference, except a few models, BMW cars are expensive as well in Germany. The German tend to invest more on their cars (incl. maintenance). It's something important - which I can understand when you drive usually 150 - 180 km/h (93 - 112 mph) in normal trafic conditions .

I see a lot a of BMW parked under car ports everywhere here in Germany.
(And I still have to see a Walmart)

It might look that simple, but it isn't. Here at least, this is strongly regulated. The only thing you can do without it being a pain is to use the power and stop the meter.

As I am currently looking into buying an electrical car, I was considering doing (almost) exactly this : Installing solar cells on the roof of the house to charge the car. It wouldn't even take that much solar cells; 20 square meters would charge the car in a reasonable amount of time. Free energy, right?

While considering the idea, a fundamental problem stuck me: Most of the time when the Sun shines, the car isn't parked at home. It is either parked in front of my office or, when I'm not working, I'm driving somewhere else, enjoying the Sun that could have charged my car. The solution to this issue was to add batteries to the concept, in order to store the Suns energy as I am away and transfer this energy back to the car at night when I am home.

Considering the car has a capacity exceeding 20 kWh, the battery solutions becomes extremely expensive - as expensive as the car itself actually (if not more). Without the battery, it's a nice expensive systems that will produce a lot of power when I don't need it. It's always possible to sell back the excess power to the utilities, but you get a loss let out of it this way and it makes your life quite complicated.

Forgetting this fundamental limitation, after doing a lot of calculation, it turned out that it would take over 20 years to amortize; and I doubt the battery system would last 20 years under the kind of stress it would be put too (nearly daily full deep cycles). And this is assuming the normal electricity prices. In fact, the charge stations are highly subsidized and your are basically paying the price large industry would pay for electricity. Suddenly your amortization period goes up over 40 years.

It's not (yet) worth it, although the technology is actually there and ready.

Conclusion : Power accumulation solution in the 20 - 40 kWh range are too expensive and power is too cheap.

There is a lot I don't understand at financial reports, but these numbers really strike me as odd.
How can you have a revenue of 731 M$ while producing in the same period about 500 M$ worth of merchandise? Said otherwise, for each car produced in Q1, they have a revenue of about 100 k$. I know the Tesla is not a cheep car, but that seems excessive. Or did I miss something here?

I wanted to add, they new very well what they were doing. An planned exactly what is happening... That some else will pay for decommissioning and they keep the cash in their pockets.

Imo, the full cost of decommissioning should be burdened to anyone who was a share holder at some point and made profit through this scheme.

In theory, this is a fine idea. In theory, it works. As you said, the funds are based on ridiculous cost predictions. Every expert knew it was not enough.

Unless the costs for decommissioning are fully independently evaluated - which is impossible - this idea will never work. And to think the independent evaluators would get the required information from the plant planners is just as utopic.

I find the conclusion that there is an absolute limit to the human life span because at some point the stem cells producing white blood cell all die out quite strange.

A few centuries ago, we could have concluded that there is an absolute limit to human life span because at some point someone can't eat anymore while he lost all his teeth. Any similar logical train of though could lead to the same conclusion.

And now, what if you find out why the cells die and manage to prevent it? Then the next thing that kills us will limit our life span, until we find out how to fix that as well. Absolute limits are difficult to set.

I'd so wish to see the tank of my car filled up after leaving it parked all day in the field.

That's bound to happen when those who can notice are found in less than 75% of the the surface of the planet.

How about just sending the stuff by snail mail? I'd bet my cup of coffee that they completely lost the expertise and interest on this form of communication.

Yes. No one drives short before sunrise in winter.

An this, is exactly why metaphors should not be weighted as facts.
