It’s Earth Day: Look Up!

Earth Day. Could the answer to our planet’s energy problems and resultant climate change be found by looking up? Every culture on earth has myths about the sun. For example, Egypt worshipped Ra, the sun god whose falcon head was crowned with a solar disk. In 1973, building upon the success of COMSAT and the Apollo Moon Landing, Peter Glaser was awarded the United States patent for solar power from space, via satellite. Honored in the spring, as the sky glows with a stronger light, Earth Day might call us to look up.

Secret of the Sphynx

Queen of the Nile, Cleopatra might grieve over the alarming change in one of the world’s most fertile deltas. As water flows north from Ethiopia, through the Sudan and Egypt to the Mediterranean, nutrients enrich the Nile River Delta. The Aswan Low Dam (1902) and Aswan High Dam (1965), along with the newly constructed Grand Ethiopian Renaissance Dam, to be the largest hydroelectric facility in Africa, are in part responsible for changing conditions. Now, less than 10% of the Nile’s waters reunite with the sea. Land subsidence and sea level rise are also factors threatening the Nile Delta. Studies of pollen and charcoal found preserved in delta sediment date back 7,000 years, to the time of the pyramids, may reveal ancient responses to similar conditions. Will the Sphinx reveal the secret?

Treasure Hunt: Grand Canal

 

King Wen, Zhou Dynasty. Image: wikimedia commons.


Yang Junxi, aged eleven, was just washing his hands, but he touched history. When the lad dipped digits into China’s Laozhoulin River, he felt an object, pulled it out and brought home a 3,000-year-old bronze sword of 10-inches (26cm) length. It was probably never used for fighting, but instead is judged by the Gaoyou Cultural Relics Bureau to be an artistic rendering, perhaps belonging to an official of the Shang or Zhou dynasties. Junxi’s father, Jinhai, and his son who donated the precious relic, have been heralded. Perhaps more treasures will be found as China plans an archeological exploration in this river that formed part of the Grand Canal. In Egypt, a similar expedition might discover Nubian art hidden beneath the High Dam at Aswan. In the future, should Lares be placed in significant infrastructure?

Power in Egypt

Giza pyramids and Sphynx, Library of Congress at loc.gov

As Egypt forms a new cabinet, will Prime Minister Hazem el-Beblawi consider rights — human and environmental? Electricity Minister Ahmed Imam, initially appointed by Morsi, must now address Egypt’s growing power needs (http://www.aljazeera.com/indepth/spotlight/egypt/2013/07/20137195138823979.html). Might Egypt draw lessons from the High Dam at Aswan?
