How many of you have “observing a Total Solar Eclipse” on your bucket list? Did you know that a total solar eclipse will occur on Monday, August 21, 2017? It will be visible in totality only within a band across the entire contiguous United States ( covering: Oregon, Idaho, Montana, Wyoming, Nebraska, Kansas, Iowa, Missouri, Illinois, Kentucky, Tennessee, Georgia, North Carolina, South Carolina). The last time a total solar eclipse was visible across the entire contiguous United States was during the June 8, 1918 eclipse.

A solar eclipse occurs when the Moon passes between Earth and the Sun, thereby totally or partly obscuring the image of the Sun for a viewer on Earth. A total solar eclipse occurs when the Moon’s apparent diameter is larger than the Sun’s, blocking all direct sunlight, turning day into darkness. Totality occurs in a narrow path across Earth’s surface, with the partial solar eclipse visible over a surrounding region thousands of kilometers wide. This eclipse is the 22nd of the 77 members of Saros series 145, which also produced the solar eclipse of August 11, 1999. Members of this series are increasing in duration. The longest eclipse in this series will occur on June 25, 2522 and last for 7 minutes and 12 seconds.

The total eclipse will have a magnitude of 1.0306 and will be visible from a narrow corridor through the United States. It will be first seen from land in the US shortly after 10:15 a.m. PDT at Oregon’s Pacific coast, and then it will progress eastward through Salem, OR, Casper, WY, Lincoln, NE, Kansas City, Nashville, TN, Columbia, SC, and finally Charleston, SC. Total Solar Eclipse will darken skies all the way from Oregon to South Carolina, along a stretch of land about 70 miles (113 kilometers) wide. People who descend upon this “path of totality” for the big event are in for an unforgettable experience. A partial eclipse will be seen for a greater time period, beginning shortly after 9:00 a.m. PDT along the Pacific Coast of Oregon.

The longest duration of totality will be 2 minutes 41.6 seconds at about 37°35′0″N 89°7′0″W in Giant City State Park, just south of Carbondale, Illinois, and the greatest extent (width) will be at 36°58′0″N 87°40′18″W near the village of Cerulean, Kentucky, located in between Hopkinsville, KY and Princeton, KY. This will be the first total solar eclipse visible from the Southeastern United States since the solar eclipse of March 7, 1970, which was only visible from Florida.

 

 


A partial solar eclipse will be seen from the much broader path of the Moon‘s penumbra, including all of North America, northern South America, Western Europe, and some of Africa.

The August 2017 eclipse will be the first with a path of totality crossing the US’s Pacific coast and Atlantic coast since 1918. Also, its path of totality makes landfall exclusively within the United States, making it the first such eclipse since the country’s independence in 1776. (The path of totality of the eclipse of June 13, 1257, was the last to make landfall exclusively on lands currently part of the US.

If you are interested in observing this event (total Solar Eclipse), below, in italics, is excerpt from “Eye Safety During Solar Eclipses” from NASA:

The Sun can be viewed safely with the naked eye only during the few brief seconds or minutes of a total solar eclipse. Partial eclipses, annular eclipses, and the partial phases of total eclipses are never safe to watch without taking special precautions. Even when 99% of the Sun’s surface is obscured during the partial phases of a total eclipse, the remaining photospheric crescent is intensely bright and cannot be viewed safely without eye protection [Chou, 1981; Marsh, 1982]. Do not attempt to observe the partial or annular phases of any eclipse with the naked eye. Failure to use appropriate filtration may result in permanent eye damage or blindness!

Generally, the same equipment, techniques and precautions used to observe the Sun outside of eclipse are required for annular eclipses and the partial phases of total eclipses [Reynolds & Sweetsir, 1995; Pasachoff & Covington, 1993; Pasachoff & Menzel, 1992; Sherrod, 1981]. The safest and most inexpensive of these methods is by projection, in which a pinhole or small opening is used to cast the image of the Sun on a screen placed a half-meter or more beyond the opening. Projected images of the Sun may even be seen on the ground in the small openings created by interlacing fingers, or in the dappled sunlight beneath a leafy tree. Binoculars can also be used to project a magnified image of the Sun on a white card, but you must avoid the temptation of using these instruments for direct viewing.

The Sun can be viewed directly only when using filters specifically designed for this purpose. Such filters usually have a thin layer of aluminum, chromium or silver deposited on their surfaces that attenuates ultraviolet, visible, and infrared energy. One of the most widely available filters for safe solar viewing is a number 14 welder’s glass, available through welding supply outlets. More recently, aluminized mylar has become a popular, inexpensive alternative. Mylar can easily be cut with scissors and adapted to any kind of box or viewing device. A number of sources for solar filters are listed below. No filter is safe to use with any optical device (i.e. – telescope, binoculars, etc.) unless it has been specifically designed for that purpose. Experienced amateur and professional astronomers may also use one or two layers of completely exposed and fully developed black-and-white film, provided the film contains a silver emulsion. Since all developed color films lack silver, they are always unsafe for use in solar viewing.

Unsafe filters include color film, some non-silver black and white film, medical x-ray films with images on them, smoked glass, photographic neutral density filters and polarizing filters. Solar filters designed to thread into eyepieces which are often sold with inexpensive telescopes are also dangerous. They should not be used for viewing the Sun at any time since they often crack from overheating. Do not experiment with other filters unless you are certain that they are safe. Damage to the eyes comes predominantly from invisible infrared wavelengths. The fact that the Sun appears dark in a filter or that you feel no discomfort does not guarantee that your eyes are safe. Avoid all unnecessary risks. Your local planetarium or amateur astronomy club is a good source for additional information.

In spite of these precautions, the total phase (and only the total phase) of an eclipse can and should be viewed without filters. It is crucial that you know when to take off and put back on your glasses; see Eye safety during a total solar eclipse

In northwestern Europe, the eclipse will only be visible as a partial eclipse, in the evening or at sunset. Only Iceland, Ireland and Scotland will see the eclipse from beginning to end; in the rest of the UK, Norway, the Netherlands, Belgium, France, Spain and Portugal, sunset will occur before the end of the eclipse. In Germany, the beginning of the eclipse will be potentially visible just at sunset only in the extreme northwest of the country. In all regions east of the orange line in the map, the eclipse will be invisible.

The Dutch Has Shown Us How To Produce Solar Energy & Art Via Bike Paths

Share

Dear Friends, Visitors/Viewers/Readers,

My associations with people from Netherlands have always been extremely positive, enthusiastic, optimistically ambitious. So, it was not surprising that during Nov. of 2014 the Dutch (people from Netherlands) developed the first Solar Bike Path (with embedded solar cells) in the world, outside Amsterdam connecting the suburbs of Krommenie and Wormerveer! This Dutch project integrated solar panels into a bike commuter path to generate power to be funneled into the national energy grid.  The crystalline silicone solar cells are encased in two layers of tempered safety glass, mounted in a concrete housing.

According to SolaRoad, it’s been a challenge to produce energy-producing slabs that are both durable and rideable by thousands of cyclists per day. “It has to be translucent for sunlight and repel dirt as much as possible,” the company says. “At the same time, the top layer must be skid resistant and strong enough in order to realize a safe road surface.” This $3.7 million project is a collaboration between the research group TNO and the government of North Holland. Its technical aspects may be found in Phys Org site.

This 70-meter or 230 feet (over two-third of the length of an NFL football field) section solar bike path is flat instead of angled to optimally take advantage of the sun, therefore the path’s panel will produce about 70% of what similar panel might produce on a rooftop.  With approximately 87,000 miles of roadways, Netherlands’s total road surface area is much larger than that of rooftops.

This project is the first step that the local government hopes will extend to 100 meter (or 328 feet) by 2016. Now that it’s been half year into the installation of the solar bike path, it’s become clear that the solar panels are outperforming expectations, having already generated 3,000 kilowatt-hours (kWh) of electricity. This is fantastic! In a space that previously generated no clean electricity, now it is functioning well and ready for further development and expansion. I have no doubt that the cost and overall efficiency of any solar roadway will continue to improve as more and more visionaries collaborate to enable such Clean Solar Renewable Dream of Solar Roadway to become a reality. Our hats off to the visionaries in Netherlands!

Another solar bike path later unveiled in the same month, but in the city of Eindhoven, Netherland, of the passive solar form, is inspired by Van Gogh’s “Starry Night”, below:

(Be sure to view the whole  video below, “Visions of Public Art: by Daan Roosegaarde”….you won’t regret it….)


Of course, it is the Dutch who would embrace a challenge by innovating first, by being efficient, in being artistic while pragmatic and remaining connected to both the past and the future……look at the Solar Bike Path at night, an inspiration by Van Gogh’s “Starry Night”.

Our future would be simply breath-takingly beautiful, if we don’t destroy our planet first…there lies the beauty of Solar Energy…for it is the answer to Energy-Pollution-Economic Prosperity-Climate Change-International Conflicts. SO, LET’S USE IT !

As long as we’re on the subject of solar roadway, let me remind you of the Indiegogo campaign here at sunisthefuture.net for Scott & Julie Brusaw of Idaho, asking for $1 million but ended up raising more than $2.2 million for their Solar Roadway R & D project. Yes, it is exciting to live in a world where dreamers and visionaries are in many places!
