From TFA :
The reserves were downgraded by 96 percent, from 13.7 billion barrels estimated by a government-funded report in 2011, to just 600 million barrels, the EIA said.
Absolute values help put things into perspective.

Or do we need more perspective? For those who prefer the typical journalistic approach to understanding numbers, it's a reduction from 872'000 Olympic pools to just under 37'200 Olympic pools.

Please stop with the half-assed facts. The average temperature of the coldest region of Antractica is -57C. That has nothing to do with the average temperature overall on the continent. What you wrote is just as stupid as saying nobody will get a heat stroke anytime soon in Pheonix; the average temperature in Vail is 11C (52F) after all.

I find it very enjoyable, yet irritating, to see people take every single effect/cause independently, somehow analyse them (while actually having no clue at all what they are doing) and come to the conclusion they are too small to be related to a trend, while missing the obvious point that independent effect can be cumulativ. Worse, different effect can promote other and accelerate the trend. And they cook up a counter arguments (again while having no clue, even of the oders of magnitude) and propagate their ignorance to others ready to believe their pseudo scientific facts.

I really have to stand on the side of other posts I read here, stating that most people are simply not open minded or bright enough to understand the data and analyse it. A large part of this is to blame on education, but when basic logic and analytic skills fail (either due to intellectual capacity or to unwillingness to use those skills) I doupt even that would help.

Comment Re:Will never work.... (Score 1) 165

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 .

Comment Good idea... with still a missing link (Score 3, Insightful) 165

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.

Comment Odd numbers (Score 3, Interesting) 131

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.

Comment Strange conclusion (Score 5, Insightful) 333

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.
