Comment Re:That will go well (Score 1) 129

Hasn't offshore gold dredging been done for years in Alaska? The environmental effects should be well known by now.

Yes, there is even a TV show about it. However, the miners in Alaska are generally poorly funded and only mine in shallow water. Someone sinking millions on dollars into it would be completely different.

Comment Re:What is higher education? (Score 0) 393

A major problem is that a lot of people go to college when really they just need job training. They don't care for, and don't receive, the real education that college degrees represent.

The entire purpose of our education system is to provide better workers for industry. Education for the sole purpose of enlightenment is a luxury our society isn't prepared to provide. It was, and will remain, something only the very upper levels of society will obtain.

Since Betacam used the same tapes (with a different format), this apparently signals the end of Betacam as well.

The entire industry has moved over to CompactFlash for the most part. Some cameras even have hot swapable arrays so a camera crew doesn't miss a second of material. Once one drive is full, the system automatically switches to the next drive and you can swap out the full drive while still recording.

They just fear consumer reaction to having another consumable fluid (that needs to be refilled every 9 thousand miles, or so) and don't want to do the heavy lifting of consumer education.

Typically, a DEF tank needs to be refilled every time the fuel tank is filled. Volkswagen cheated to get to that 9k mile interval.

When DEF was first introduced, there was a concern that the infrastructure wasn't available to refill the tanks. Manufacturers were trying to avoid using DEF, or extending fill intervals as long as possible to prevent issues if DEF wasn't available.

Which are all very different from those found in tiny passenger cars. It's trivial to make a very large diesel engine meet emission standards.

As a diesel emissions engineer, I cannot emphasize enough how incorrect this statement is. All diesel engines function on the same principles. Diesel emissions regulations are the most strict for small engines. The EPA assumes that smaller engines (car and truck) are less expensive to develop than large engines. Medium and large engine (locomotive and ship) regulations lag behind the small engines by a few years so they can benefit from the work already done by the small engine manufacturers.

Right now it appears all types of diesel engines will eventually end up with similar engine technology (EGR+SCR). There might be some slight differences in execution due to the duty cycle differences. For example, a ship at sea has a very different duty cycle than a semi in traffic.

Of course, emission TESTING standards might get improved in ways that can catch cheaters faster...

Absolutely! The fact that an automaker cheated says the standards are strict. The fact they got a way with it as long as they did says the system lacks proper verification.

Comment Never Ban a Technology (Score 3, Insightful) 144

Once you ban a technology, you are also banning any development on it. It may have some undesirable effects now. Ban those effects. If the technology is worthwhile, someone will figure out a way to solve the problems.

Also, just because there is one bad egg doesn't mean an entire technology is bad.

I heard a segment on America's Test Kitchen who presented a general summary of his research that essentially said that the people with the longest lifespan tend to have the lowest lifetime caloric intake. He noted clearly there is a cut off point to the benefits of eating less, but eating less of everything over a lifetime is indeed a positive as long as you aren't starving your cells of what they need. At this point, I've forgotten the author, so you can take it with a grain of salt if you don't mind risking your heart health with an increase in your sodium intake...

This is the most sensible, and rational thought on nutrition I have ever heard. It's basically what I said above. Eat just enough of whatever you want to keep you alive, and nothing more.

As usual, the concept of moderation goes *woosh* over people's heads as they furiously go about constructing their strawmen.

Except these stories never seem to focus on moderation. They focus on "cutting". You can't cut everything, you will starve. However, it seems our society has rejected moderation as something viable.

My personal opinion is, eating will kill you. Not eating will kill you faster. We're all going to die at some point. Eat just enough of whatever you want so you don't starve. Don't eat more than that.

carbohydrates? glucose? fructose? galactose? sucrose? maltose? lactose?

If you cut them all, what would you eat? Meat causes cancer. Where would you get the calories necessary to survive?

Seems to me we have spent thousands of years to come to the same conclusions as the ancient Greeks. "Nothing to Excess."

Comment Education is a Business (Score 1) 278

Education is a business like any other. The product our education system produces are productive members of society. With that as our goal, the true test is evaluating if that goal was met. Interview former students and their employers. Find out if they were prepared enough after leaving school.

There is a drawback to this proposed approach. Obtaining this information will be too slow. It could be up to 20 years before we find out our kindergartners aren't up to snuff. We need a faster way to evaluate the situation. That is where standardized tests come in. The standardized testing allows schools to have cascading control over the students to make sure they stay on the path to becoming productive members of society. It may not be adding value to the students, but it adds value to our system.

Economics is a social "science".

Correct, economics is a social science. There is even some hard science under there as well (think manufacturing). Money and finance are tools humans have engineered to harness the fundamental principles of economics.

Don't be fooled into thinking economics wouldn't exist without money. It would still exist because there is efficiency to be gained by trading, and that's what economics is really focused on.

There is very little future in being right when your boss is wrong.
