Inalienable Rights This is a response to the “No More State Theatre” in your August 24th edition. I think I will not be the only response to this pathetic and narrow-minded letter that seems rather out of place in the northern Michigan that I know. To think we will not be getting your 25 cents for the movie you refused to see, but more importantly we will be without your “two cents” on your thoughts of a marriage at the State Theatre...

Enthusiastically Democratic Since I was one of the approximately 160 people present at when Senator Debbie Stabenow spoke on August 14 in Charlevoix, I was surprised to read in a letter to Northern Express that there was a “rather muted” response to Debbie’s announcement that she has endorsed Hillary Clinton for president...

Not Hurting I surely think the State Theatre will survive not having the homophobic presence of Colleen Smith and her family attend any matinees. I think “Ms.” Smith might also want to make sure that any medical personnel, bank staff, grocery store staff, waiters and/or waitress, etc. are not homosexual before accepting any service or product from them...

Stay Home I did not know whether to laugh or cry when I read the letter of the extremely homophobic, “disgusted” writer. She now refuses to patronize the State Theatre because she evidently feels that its confines have been poisoned by the gay wedding ceremony held there...

Keep Away In response to Colleen Smith of Cadillac who refused to bring her family to the State Theatre because there was a gay wedding there: Keep your 25 cents and your family out of Traverse City...

Celebrating Moore And A Theatre I was 10 years old when I had the privilege to see my first film at the State Theatre. I will never forget that experience. The screen was almost the size of my bedroom I shared with my older sister. The bursting sounds made me believe I was part of the film...

Outdated Thinking This letter is in response to Colleen Smith. She made public her choice to no longer go to the State Theater due to the fact that “some homosexuals” got married there. I’m not outraged by her choice; we don’t need any more hateful, self-righteous bigots in our town. She can keep her 25 cents...

Mackinac Pipeline Must Be Shut Down Crude oil flowing through Enbridge’s 60-yearold pipeline beneath the Mackinac Straits and the largest collection of fresh water on the planet should be a serious concern for every resident of the USA and Canada. Enbridge has a very “accident” prone track record...

Your Rights To Colleen, who wrote about the State Theatre: Let me thank you for sharing your views; I think most of us are well in support of the first amendment, because as you know- it gives everyone the opportunity to express their opinions. I also wanted to thank Northern Express for not shutting down these types of letters right at the source but rather giving the community a platform for education...

No Role Model [Fascinating Person from last week’s issue] Jada quoted: “I want to be a role model for girls who are interested in being in the outdoors.” I enjoy being in the outdoors, but I don’t want to kill animals for trophy...

Spy Drones

Harley Sachs - September 1st, 2005

When we first sent men into orbit they reported that the only man-made object visible from space was the Great Wall of China. Now astronauts report that at their altitude of about 100 miles they can plainly observe the environmental devastation caused by humans. Deforestation, the resulting erosion, and coastal pollution are visible from space.
Unfortunately, satellites to monitor these developments are expensive to launch and they orbit the earth about every 90 minutes. It would be better if observations could be made continuously at a lower altitude. Enter the UAV, the Unmanned Aerial Vehicles.
The goal is to develop a drone that will fly indefinitely over a chosen area, sending down pictures to observers on earth. The UAV will be the latest evolution of the unmanned drones first developed by the Israelis in their continuous struggle against Palestinian terrorism. The Israeli drones, controlled from the ground, sent back television signals to pinpoint the sites, for instance, where rockets were being launched.
The Israeli idea was further developed for the U.S. forces and it is estimated that as many as 800 such drones are now patrolling the skies of Afghanistan and Iraq. The drones are so small that they are virtually invisible to conventional radar. Follow the path, for instance, of a helium filled balloon some child has released. It rises higher and higher, but soon your eyes are no longer sharp enough to spot it. That’s the beauty of a drone that’s invisible from the ground and doesn’t risk the life of a pilot or the expense of a slow-flying plane if it’s shot down.
But the ideal UAV must fly indefinitely, circling the target area possibly for months without landing. To fly indefinitely means no refueling. To do that requires solar power.
After the first human-powered airplane crossed the English Channel, the feat was repeated by a solar-powered airplane. Of course, it could fly only as long as the sun provided energy to the panels on the wings.
Now for another acronym: HALE, standing for high-altitude long-endurance. A new HALE drone, built by former UK defense research lab QinetiQ, will push the boundaries for eternal planes a bit further. What it needs to keep flying at night is battery power. As Dr. Rogoyski, a key authority on the project, reports, the key to success of the HALE UAVs is the rapid advance in solar panels and lithium batteries.
If a lithium battery array with a 20% efficiency can be developed, those high-flying HALE drones will be able to stay up indefinitely, able to reach anywhere on the earth in less than 24 hours. Then those drones will be able to monitor crops, drought, and other agricultural factors. Drones are not just for fighting terrorists anymore.
I remember building model airplanes when I was a kid in the days of balsa wood, tissue paper, and propellers powered by a rubber band. My biggest model was able to take off and actually fly a few feet before running out of rubber power. Imagine what it would have been like to fly it on solar power alone.
Of course, that’s what Pegasus is supposed to do. It’s hard to imagine a plane with a wing span of 16m and a light weight of 27kg (that’s 53.3 feet and 52 pounds for the metrically challenged). One person could easily carry it. To achieve that the solar panels must be paper thin, the skeleton of ultra light carbon fibers, and the batteries and the transmission equipment incredibly small and lightweight.
The drones already developed have broken altitude records, flying as high as 94,000 feet, the edge of space. The HALE will fly in the stratosphere. Maybe they should have named it Icarus.
