Comment Manufacturers cheat on "Take Home" EPA test. (Score 2) 374

First the current 5 cycle EPA test isn't limited to 60mph, it goes up to 80 MPH:
http://www.fueleconomy.gov/feg/fe_test_schedules.shtml

That isn't the real problem. The real problem is that 85% of "EPA Testing" is actually done by the manufacturer themselves. In effect this is a Take home test.
http://www.caranddriver.com/features/the-truth-about-epa-city-highway-mpg-estimates
"While the public mistakenly presumes that this federal agency is hard at work conducting complicated tests on every new model of truck, van, car, and SUV, in reality, just 18 of the EPA’s 17,000 employees work in the automobile-testing department in Ann Arbor, Michigan, examining 200 to 250 vehicles a year, or roughly 15 percent of new models. As to that other 85 percent, the EPA takes automakers at their word—without any testing—accepting submitted results as accurate. "

Since EPA MPG plays a big part in overall advertising campaigns, and potential EPA penalties, there is strong temptation for manufacturers to cheat.

Two years ago Hyundai had an ad campaign featuring how all models of many of it's cars got 40MPG highway without needed special models. Hyundai scored big increase in sales. But later testing a Consumer Reports showed a few of Hyundais models got less than 40 MPG in CR testing. This is ODD because CR testing is more straight forward and the vast majority of cars beat their EPA Highway rating when CR tests them on it's own test. So the CR testing is something of a Sanity check for catching cheaters. Eventually Hyundai was found to have a systemic "mistake" in their testing (AKA cheating). They had to roll back mileage claims across the board and give payouts to customers.

The discrepancy between CR and EPA for Hyundai models before they were caught cheating was 1-3 MPG.

Fords new Hybrids are now falling short by 6-9 MPG and Ford has a new (successful) Ad campaign targeting Toyota, claiming better fuel economy. These new Ford hybrids are the first to make significant sales inroads against Toyota. If anything MPG advertising has even more effect on Hybrid sales.

It isn't hard to see how Fords interests are benefited by high test scores, on a test they administer to themselves, even more than they were for Hyundai before they were caught cheating. It certainly smells like something rotten in Dearborn Mi.

Comment Maybe for range extension, but not day to day. (Score 1) 171

I looked up the recycling efficiency of Aluminum in this case and found it was about 15%. This is worse efficiency than the lowest number you see for an Gas Engine. So using something like this for day to day usage seems out of the question.

But with the right packaging it might be a decent range extender in addition to a Lithium main battery pack.

And this company failed due to the current trend in American economics. Mr. Fisker wanted to invest and build to create a product to sell.

This company failed becuase it had a poorly engineered product, with outsourced drivetrain, and outsourced production. That product was one of the most unreliable cars produced in the 21st century so far in an era when cars are getting more reliable.

Mr. Fisker most likely departed because he wanted out of a sinking ship. There was no investing to save this turkey.

Comment Neil Young and the Placebo effect. (Score 1) 749

Neil Young is an aging rocker with hearing damage. There is no way he can tell the difference except in his own mind.

Even among people good hearing, only a minority can detect a difference between lossless and properly encoded higher bit rate (~200K+) lossy.

The hubbub over this is almost all placebo effect and snobbery.

Comment Re:Winter Months (Score 2) 646

In the depths of winter we get ~9 hours of daylight.

Major Commuting starts are 7AM in the morning. Major Commuting ends after 6 PM in the evening. That's 11 hours.

No matter how you fiddle with it, most people are going to commute in the dark in the morning, or the evening, or BOTH.

I wouldn't care if it is DST all year or Standard time all year, but the switch really should go.

The Switch is definitely killing people pointlessly (Increased heart attacks and fatal accidents).

Comment I never understood why we didn't use DST all year. (Score 1) 646

I get the idea of more evening sun in the summer, but once you recognize that, what is the benefit of switching it back in winter.

In the winter I end up going to work in the dark and coming home in the dark anyway and when the day is long enough for it to matter, I would still prefer to go to work in the dark and come home in light.

Figure out the summer optimum, set it an leave it. The winter setting is nearly irrelevant.

Comment I think Porting to Metro would be higher priority. (Score 1) 188

Let's revisit after they have a port for their own mobile GUI, before we start thinking they are going to port to Apple (or are holding back doing so).

Such a port to a radically different GUI paradigms is going to be a major re-write. It will take years. It isn't simple a case of recompile for new architecture.

Comment Biggest difference was charging, not temperature. (Score 3, Insightful) 525

Some have commented on the temperature difference or the fact that Broder did an overnight, stop with the car unplugged.

But the real difference is that Broder who was ostensibly testing the supercharging network, short charged it the Milford Supercharger.

The CNN folks fully charged theirs.

Broder has given multiple questionable excuses for that short charge, so it is looking more and more like it was setting the Tesla up for failure to drama up his story.

 

Comment 10F difference. In 30s for NYT, 40's for CNN (Score 2) 525

There seems to be a misconception on the temperature difference.

Go Read Broders piece, He said he recieved the car on a Sunny 30F day. He mentioned the temperature while driving was in 30's on day 1.

It only hit 10F overnight while the car was parked. This was the major difference. He parked the car overnight, CNN kept going.

Comment $1000 tablets don't deserve a free ride on this. (Score 5, Insightful) 418

There are a lot of responses here that say "All tablets are like that".

First, Many of those tablets cost $200 (Nexus). It is a lot more acceptable to have a sealed $200 device than a sealed $1000 device, regardless of form factor.

Second, Almost no other computing device is sealed to this extent with an inch wide strip of tar like adhesive that needs a heat-gun to pry apart (who knows how well it will go back together). I take nearly everything apart, but I would mess with this kind of extreme adhesive job, especially on a $1000 device.

Third. It isn't even about repairs. If this was pure reliable solid state, it wouldn't be a big deal, those parts could run for decades. But this has two fans, meaning they will accumulate dust/have bearing failures, and in few years need replacing/cleaning, it has batteries with short finite life that will fail in few years, the SSD is small size and has an OS with propensity to write a lot to it (swap files) etc, and has a significant chance of failure. These should be considered serviceable components, because chances are significant that one or more of them will need service in a few years. Having them sealed, non-serviceable in $1000 device is unacceptable (IMO).

The point is that applies to playing normal games, going for a jog, having beers with your buddies.

There is no evidence that brain games are any better than other activities for brain health.

In fact simple exercise, and socializing are likely better.
