Shallow geothermal energy – high efficient heating and cooling of hotel complexes and commercial buildings with borehole heat exchanger systems as seasonal storage for heat and cold The utilization of shallow geothermal energy with borehole heat exchangers and heat pumps for heating and cooling of buildings is very popular in Europe due to low costs of operation and high operating reliability. These systems have the highest rates of growth of all energy supply systems in Europe. In order to provide a productive and comfortable climate for a living and working environment, buildings have an anti-cyclical demand of heat and cold. During the summer, when abundant heat is available, they have to be air-conditioned, while in wintertime, when cold is at disposal, the buildings have to be heated. Especially the heat and cold supply for hotels and commercial buildings is a challenge, as their huge energy demand needs to be satisfied with a reliable and cost-effective solutio

In this view of Egypt, we see a population almost completely concentrated along the Nile Valley, just a small percentage of the country’s land area. The Nile River and its delta look like a brilliant, long-stemmed flower in this astronaut photograph of the southeastern Mediterranean Sea, as seen from the International Space Station. The Cairo metropolitan area forms a particularly bright base of the flower. The smaller cities and towns within the Nile Delta tend to be hard to see amidst the dense agricultural vegetation during the day. However, these settled areas and the connecting roads between them become clearly visible at night. Likewise, urbanized regions and infrastruct

For instance, nighttime lights in some Middle East cities were 50 to 100 percent brighter during the holy month of Ramadan. The maps on this page show changes in lighting intensity and location on the Arabian Peninsula and in the countries along the eastern Mediterranean coast. They are based on data from the Visible Infrared Imaging Radiometer Suite (VIIRS) on the Suomi NPP satellite. The maps compare the night light signals from the months of Ramadan in 2012–2014 (parts of July and August in these years) to the average light output for the rest of 2012 to 201

JOHANNESBURG'S gold mining industry was established when a large gold reef was accidentally discovered on a remote farm in 1886, triggering a massive gold rush by thousands of speculators.   The City of Johannesburg is littered with Defunct shafts, Old Mine Workings and Mine Waste Dumps... all a history to the name Egoli - The City of Gold... The Powerhouse of Africa...     Zaheer Bux - Gold Exploration - Central Rand Goldfield Within 10 years, there was a fully fledged town on the same spot; within 30 years it was South Africa's largest city. Today Johannesburg is Africa's biggest city, ringed by the deepest gold mines in the world. The Central Rand Goldfield - Johannesburg Consolidated Main Ree
