Trump should avoid self-dealing President-elect Donald Trump plans to turn over running of The Trump Organization to his children, who are also involved in the transition and will probably be informal advisers during his administration. This is not a “blind trust.” In this scenario Trump and family could make decisions based on what’s best for them rather than what’s best for the country...

Trump the change we need?  I have had a couple of weeks to digest the results of this election and reflect. There is no way the selection of Trump as POTUS could ever come close to being normal. It is not normal to have a president-elect settle a fraud case for millions a couple of months before the inauguration. It is not normal to have racists considered for cabinet posts. It is not normal for a president-elect tweet outrageous comments on his Twitter feed to respond to supposed insults at all hours of the early morning...

Health care system should benefit all It is no secret that the health insurance situation in our country is controversial. Some say the Affordable Care Act is “the most terrible thing that has happened to our country in years”; others are thrilled that, “for the first time in years I can get and afford health insurance.” Those who have not been closely involved in the medical field cannot be expected to understand how precarious the previous medical insurance structure was...

Christmas tradition needs change The Christmas light we need most is the divine, and to receive it we do not need electricity, probably only prayers and good deeds. But not everyone has this understanding, as we see in the energy waste that follows with the Christmas decorations...

CORRECTIONS & CLARIFICATIONS 

A story in last week’s edition about parasailing businesses on East Grand Traverse Bay mistakenly described Grand Traverse Parasail as a business that is affiliated with the ParkShore Resort. It operates from a beach club two doors down from the resort. The story also should have noted that prior to the filing of a civil lawsuit in federal court by Saburi Boyer and Traverse Bay Parasail against Bryan Punturo and the ParkShore Resort, a similar lawsuit was dismissed from 13th Circuit Court in Traverse City upon a motion from the defendant’s attorney. Express regrets the error and omission.

A story in last week’s edition about The Fillmore restaurant in Manistee misstated Jacob Slonecki’s job at Arcadia Bluffs Golf Course. He was a cook. Express regrets the error.

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.
