Letters 10-24-2016

It’s Obama’s 1984 Several editions ago I concluded a short letter to the editor with an ominous rhetorical flourish: “Welcome to George Orwell’s 1984 and the grand opening of the Federal Department of Truth!” At the time I am sure most of the readers laughed off my comments as right-wing hyperbole. Shame on you for doubting me...

Gun Bans Don’t Work It is said that mass violence only happens in the USA. A lone gunman in a rubber boat, drifted ashore at a popular resort in Tunisia and randomly shot and killed 38 mostly British and Irish tourists. Tunisian gun laws, which are among the most restrictive in the world, didn’t stop this mass slaughter. And in January 2015, two armed men killed 11 and wounded 11 others in an attack on the French satirical magazine Charlie Hebdo. French gun laws didn’t stop these assassins...

Scripps’ Good Deed No good deed shall go unpunished! When Dan Scripps was the 101st District State Representative, he introduced legislation to prevent corporations from contaminating (e.g. fracking) or depleting (e.g. Nestle) Michigan’s water table for corporate profit. There are no property lines in the water table, and many of us depend on private wells for abundant, safe, clean water. In the subsequent election, Dan’s opponents ran a negative campaign almost solely on the misrepresentation that Dan’s good deed was a government takeover of your private water well...

Political Definitions As the time to vote draws near it’s a good time to check into what you stand for. According to Dictionary.com the meanings for liberal and conservative are as follows:

Liberal: Favorable to progress or reform as in political or religious affairs.

Conservative: Disposed to preserve existing conditions, institutions, etc., or to restore traditions and limit change...

Voting Takes A Month? Hurricane Matthew hit the Florida coast Oct. 6, over three weeks before Election Day. Bob Ross (Oct. 17th issue) posits that perhaps evacuation orders from Governor Scott may have had political motivations to diminish turnout and seems to praise Hillary Clinton’s call for Gov. Scott to extend Florida’s voter registration deadline due to evacuations...

Clinton Foundation Facts Does the Clinton Foundation really spend a mere 10 percent (per Mike Pence) or 20 percent (per Reince Priebus) of its money on charity? Not true. Charity Watch gives it an A rating (the same as it gives the NRA Foundation) and says it spends 88 percent on charitable causes, and 12 percent on overhead. Here is the source of the misunderstanding: The Foundation does give only a small percentage of its money to charitable organizations, but it spends far more money directly running a number of programs...

America Needs Change Trump supports our constitution, will appoint judges that will keep our freedoms safe. He supports the partial-birth ban; Hillary voted against it. Regardless of how you feel about Trump, critical issues are at stake. Trump will increase national security, monitor refugee admissions, endorse our vital military forces while fighting ISIS. Vice-presidential candidate Mike Pence will be an intelligent asset for the country. Hillary wants open borders, increased government regulation, and more demilitarization at a time when we need strong military defenses...

My Process For No I will be voting “no” on Prop 3 because I am supportive of the process that is in place to review and approve developments. I was on the Traverse City Planning Commission in the 1990s and gained an appreciation for all of the work that goes into a review. The staff reviews the project and makes a recommendation. The developer then makes a presentation, and fellow commissioners and the public can ask questions and make comments. By the end of the process, I knew how to vote for a project, up or down. This process then repeats itself at the City Commission...

Regarding Your Postcard If you received a “Vote No” postcard from StandUp TC, don’t believe their lies. Prop 3 is not illegal. It won’t cost city taxpayers thousands of dollars in legal bills or special elections. Prop 3 is about protecting our downtown -- not Munson, NMC or the Commons -- from a future of ugly skyscrapers that will diminish the very character of our downtown...

Vote Yes It has been suggested that a recall or re-election of current city staff and Traverse City Commission would work better than Prop 3. I disagree. A recall campaign is the most divisive, costly type of election possible. Prop 3, when passed, will allow all city residents an opportunity to vote on any proposed development over 60 feet tall at no cost to the taxpayer...

Yes Vote Explained A “yes” vote on Prop 3 will give Traverse City the right to vote on developments over 60 feet high. It doesn’t require votes on every future building, as incorrectly stated by a previous letter writer. If referendums are held during general elections, taxpayers pay nothing...

Beware Trump When the country you love have have served for 33 years is threatened, you have an obligation and a duty to speak out. Now is the time for all Americans to speak out against a possible Donald Trump presidency. During the past year Trump has been exposed as a pathological liar, a demagogue and a person who is totally unfit to assume the presidency of our already great country...

Picture Worth 1,000 Words Nobody disagrees with the need for affordable housing or that a certain level of density is dollar smart for TC. The issue is the proposed solution. If you haven’t already seen the architect’s rendition for the site, please Google “Pine Street Development Traverse City”...

Living Wage, Not Tall Buildings Our community deserves better than the StandUp TC “vote no” arguments. They are not truthful. Their yard signs say: “More Housing. Less Red Tape. Vote like you want your kids to live here.” The truth: More housing, but for whom? At what price..

Harley L. Sachs - April 12th, 2010
Piezoelectricity: Power under pressure
You probably never heard of piezoelectricity but you have used it if you have an outdoor grill with a push-button igniter. The phenomenon gets its name from the Greek word piezo which means push. Push on a ceramic crystal and you get a spark of electricity which, in the case of your grill or the gas/electric refrigerator in your camper, ignites the propane. It’s a strange phenomenon which may someday become a source of electricity by harnessing the pressure exerted on highways or railway tracks.
This phenomenon was first discovered and described by Pierre and Jacques Curie in 1880. It was then just a laboratory curiosity, but it later found application in microphones, which employ electric energy created by the pressure of sound waves on crystals.

Piezo electricity was utilized in 1917 for submarine detection in World War I. That early form of sonar sent out a chirp or ping that bounced off submerged submarines. Currently, you may have seen the piezoelectrical effect in dance halls where someone stepping on a portion of the floor lights it up.
Now there’s an Israeli company called Innowattech, affiliated with the Technion, the country’s premier engineering university, which plans to use piezoelectric pressure plates built into a highway to generate electricity.
The idea developed at the Technion is to bury piezo plates in a stretch of highway to generate electricity from the pressure as cars pass by. Utilizing the energy of a car’s tires pressing down on the highway does not affect the vehicle’s performance. Of course, to generate a continuous flow, you need a continuous flow of traffic, which can only be found during rush hour.
An alternative is to put the piezo generators under railway ties where train traffic is heavy, like the New York or London subway system, where trains are passing every few minutes and continuous pressure is applied to the rails somewhere in the system.

If you ever watched what the rails do as a freight train passes over them, you may have seen how the portion of the track under the wheels of the cars sinks and the portion between the wheels lifts. Some of that energy can be converted to electricity.
The challenge is to link those brief sparking moments so they produce a continuous flow of current. You can’t get that from your grill igniter, but imagine a whole row of them triggered sequentially. The Innowattech plan is to build piezo generators under an experimental 90-foot strip of highway outside Tel Aviv, preliminary to a later half-mile section of road. The projected production of electricity from the half mile is expected to be about 100 kw of electricity, enough to power about 40 houses.
Cost benefit calculations suggest that electricity generated under a highway would cost between 3 and 10 cents a kilowatt hour, comparable to what is generated by wind energy. Fossil fuels cost about 5 cents per kilowatt and solar about the same.
The highway piezo generators will be buried about one inch below the surface. The generators are to go under asphalt, which is flexible, unlike concrete.

That all sounds pretty good, but I wonder how long such an installation will last. Though the piezo material can last 30 years, I haven’t seen a stretch of highway in the United States that can go that long before it develops deep potholes. Maybe the Israeli roads are built better.
Putting the piezo generators under railway ties sounds like a more durable alternative.
You have to give the Israelis credit for coming up with new ideas and innovations. Israel has more Ph.Ds per 100,000 than any other country and produces more patents per 100,000 population. A highway that generates electricity is only one of them. Uri Amit, president of Innowattech, believes piezo generated electricity has a future.
There’s even a plan to light a passageway in a high traffic area in Chicago simply by the pressure of people’s footfalls on a piezo-wired sidewalk!
With all those alternative sources of energy, what next?
