Comment Re:Or, it could be unrelated to actually extending (Score 1) 286

I think the tipping point for electric vehicle range would be 1000 miles on one charge.

I disagree. The human body has needs too. Most people want to stop to eat and use a restroom around every 4 hours. If you can charge a car in the time it takes to have a leisurely meal, and then drive for another four hours, it should be fine for cross country driving. The Tesla Model S's largest battery provides just enough energy to propel the vehicle at highway speeds for about 4 hours. Also, the supercharger can charge the battery in about an hour. It's almost like they planned it that way!

I'd like to see Tesla partner with a chain of diners, like Denny's, that's open 24 hours a day.

Comment An Intern (Score 1) 144

My first semester under my university's co-op program I was a human issue tracker. People would contact me with issues and I would track them in an excel spreadsheet. I would then follow up with various stake holders to track the progress on each item.

Thinking back on it, it was strange. I spent my college internship acting as a manager...

Depending on the volume of issues, this doesn't have to be a full time job. One person just needs to be the point of contact, document, and follow up on the items.

The AP covered it in 2013, it is not like we didn't know, we just did not pay attention.

That article you are referencing is about a different topic entirely. There is a difference between having public and private accounts, both residing on the organization's servers, and what Clinton did. Kathleen Sabelius's three email accounts were all @hhs.gov accounts. They would have been subjected to the same security and record keeping requirements as anyone in the administration. This is a common practice in private industry, and I expect it to occur in the public sector as well. A well known public figure wouldn't be able to function with every lunatic sending them emails constantly. Therefore you have the public email address forwarded to a team of assistants, and the private email address to conduct day-to-day tasks.

What Clinton did was use a personal email account, like G-mail, to conduct business.

The fact they thought they could resolve the "telemetry problem" without access to the rocket, tells me it wasn't anything on the rocket. They said the rocket was healthy when they aborted the launch. I'm guessing they were having issues with the air-force radar long before the launch was scrubbed. I'm speculating it was providing suspicious data, and then suddenly no data at all. Perhaps they thought the radar system just needed to be restarted, and then it never came back online.

I was told my clock can be fixed by having the dealership reinstall the OS. That would take about 6 hrs they say, which I can't really be without my work vehicle for that long so I've just lived with it.

My wife's car has an older version of Sync, and I can update it myself by downloading a file to a USB drive and plugging it into the car. It took less than an hour. For some reason, dealer mechanics can't do anything computer related in less than a day.

We emissions-test everything 1967+ that was not exempt at manufacture.

Who is we? The federal emissions regulations don't require testing of every vehicle. That is up to the states. Most of them don't check.

Allow me to explain how emissions testing works. A vehicle is assigned an "end of useful life" by the EPA based on the type of vehicle. The manufacturer then ages the vehicle artificially by running it 24/7. The manufacturer then has to test the aged vehicle to show compliance. This typically means the emissions from a new vehicle are much lower than an old one. Even if it is working properly.

California added an diagnostic requirement that says your "Check Engine" light has to come on if it's likely you aren't meeting the emissions regulations. How many people drive around with that thing on?

I'm simplifying a bit, but the point is, the great recession has caused a lot of vehicles to be driven past their declared "end of useful life". Even if they are still meeting the emissions requirements. They will be higher.

Industrial applications - Will let Walmart cut a few more cents off their prices and still make a profit. Barely noticeable.

Retail profit margins are razor thin as it is. The reason they make so much money is the volume. If they can shave a few cents off of each of the billion products they sell each year, that's tens of millions of dollars! That's very noticeable!

Of all the possible applications for the IoT, industrial applications are by far the most promising for that reason. Some industries are so competitive that successful companies look at fractions of a percent improvements as major investment opportunities. Industries that don't have that kind of high volume, fiercely competitive market, won't invest in this technology. However, the logistics industry is currently investing heavily in this technology.

And modern diesel engines emit more NO2 than they used to.

I believe you mean N2O. NO2 is broken down by SCR. Unfortunately, N2O can be formed as a side effect of the SCR reactions. However, N2O is regulated as a greenhouse gas.

Comment Re:Do we have 4G now? (Score 2) 216

I kind of got the impression most things being called 4G weren't even properly that.

You are correct. The ITU defined 4G, and none of the carriers followed the standard. Instead, they strong armed the ITU to change the definition of 4G to fit the technology they had already deployed. I suspect the same will happen with 5G as well.

No - it's not even a question. Bury the lines and you will remove a large number of causes for power outages.

My parents live in a neighborhood with buried power lines. Yeah, on average the power goes out less often. However, they've had a recent issue with the buried lines decaying after 30+ years underground. When that happens, it's a much longer, and more expensive repair.

The thing that bothers me is well meaning landowners planting trees near power lines. Personally, I blame schools that hand out saplings to children without proper education. Yeah, they look nice when they are small. They don't stay small.

Comment Elon Musk's Opinion (Score 1) 293

Elon Musk really hates hydrogen as a fuel. Not just for cars, but even for rockets.

The energy cost of methane is the lowest and it has a slight Isp (specific impulse) advantage over kerosene...it does not have the pain-in-the-ass factor that hydrogen has

I know hydrogen has a high "pain-in-the-ass" factor, but are electric cars that much better?
