Facts About Trails I would like to correct some misinformation provided in Kristi Kates’ article about the Shore-to-Shore Trail in your April 18 issue. The Shore-to-Shore Trail is not the longest continuous trail in the Lower Peninsula. That honor belongs to the North Country Trail (NCT), which stretches for over 400 miles in the Lower Peninsula. In fact, 100 miles of the NCT is within a 30-minute drive of Traverse City, and is maintained by the Grand Traverse Hiking Club...

North Korea Is Bluffing I eagerly read Jack Segal’s columns and attend his lectures whenever possible. However, I think his April 24th column falls into an all too common trap. He casually refers to a nuclear-armed North Korea when there is no proof whatever that North Korea has any such weapons. Sure, they have set off some underground explosions but so what? Tonga could do that. Every nuclear-armed country on Earth has carried out at least one aboveground test, just to prove they could do it if for no other reason. All we have is North Korea’s word for their supposed capabilities, which is no proof at all...

Double Dipping? In Greg Shy’s recent letter, he indicated that his Social Security benefit was being unfairly reduced simply due to the fact that he worked for the government. Somehow I think something is missing here. As I read it this law is only for those who worked for the government and are getting a pension from us generous taxpayers. Now Greg wants his pension and he also wants a full measure of Social Security benefits even though he did not pay into Social Security...

Critical Thinking Needed Our media gives ample coverage to some presidential candidates calling each other a liar and a sleaze bag. While entertaining to some, this certainly should lower one’s respect for either candidate. This race to the bottom comes as no surprise given their lack of respect for the rigors of critical thinking. The world’s esteemed scientists take great steps to preserve the integrity of their findings. Not only are their findings peer reviewed by fellow experts in their specialty, whenever possible the findings are cross-checked by independent studies...

Rare Earths

A.T. Jakeway - September 20th, 2011  
Our technological vulnerability

Remember this poem from your school days? “For the want of a nail, a shoe was lost/ For the want of a shoe, a horse was lost/ For the want of a horse, a rider was lost/ For the want of a rider, a message was lost/ For the want of a message, a battle was lost/ For the want of a battle, a country was lost/ For the want of a nail.”

This situation has been repeated again and again and is still happening.

In World War II with the German steel factories turning out weapons for the Nazi forces, an insurance specialist was called in by the Allies to identify the weak link in the German military production. The simple solution was this: German steel manufacturing demanded sulfuric acid. The source was a single plant in southern Germany and the acid was produced in ceramic vats. All that was needed was for a spy saboteur to take a hammer to the acid vats and break them. This was done and German steel production was set back for months until new ceramic vats could be made.

During the Vietnam War when the primary infantry weapon was the M16 rifle, the ammunition was produced in one factory in East Alton, Illinois. As the story goes, one day a carpenter moved an electrician’s cable. Carpenters weren’t supposed to touch electricians’ stuff, and there was a strike that shut down the production of the M16 ammunition. In a short time the troops in Vietnam were running out of ammunition, and the government had to see that a couple more factories were contracted to make more ammunition, even after the strike ended, all because of a minor labor dispute.

I learned that only one company in the country made brushes for electric motors, If they went out of production that would stop all companies from building electric motors.

JAPAN & PAINT

Today, because of the earthquake and tsunami in Japan, a key ingredient for U.S. auto production is no longer available. It is pigment for the paint used in auto production. That is the weak link.

More sinister is this one: five state-of-the art foundries were built in Spain for the man ufacture of windmills to generate electricity.

You may have seen some of those massive constructions. They are as tall as 300 feet, like a 30-story building, but the key part is the generator that makes the electricity. It’s a small unit, but the construction of the generators requires rare earth.

Rare earths are mineral substances that are hard to find with names like Yttrium, Praseodymium, Samerium, Europium, Erbium and Promethium. Many are used for the construction of lasers (Dysprosium, Holmium, Erbium, Ytterbium, etc.). Need a nuclear battery? Then you’ll need the rare earth Promethium to build one. Aerospace aluminum, rare earth magnets, vanadium steel and many other technologically-advanced materials and products all rely on rare earths (ie., Scandium Dysprosium, Erbium).

In the case of Spain’s windmill generators, the one mine in America that produced the rare earth needed for a key part was closed because a Chinese source was more plentiful. Ah, but the Chinese also build windmills and they have announced that they are curtailing export of the essential rare earths. As a result, the five Spanish foundries are closed down, and China is on the way to cornering the world windmill production.

THE HELIUM MARKET

The United States did something similar to Germans in the days of the Hindenberg and other lighter-than-air ships of the 1930s. The U.S. is the world’s source for helium and would not sell it to the technologically-advanced Germans, so they were forced to substitute flammable hydrogen for their dirigibles. Result: poof! The fiery crash of the Hindenberg at Lakehurst, New Jersey in 1937 was the death knell for airships. That was in spite of a flawless record of the Graf Zeppelin in making more than 70 trips from Germany to South America.

The future of an industry -- even of a country -- can depend on a single vulnerable element, even if it is as simple as a horseshoe nail. For the want of a nail.
