The first commercial flight landed on the British island of St. Helena a few days ago. It was the first passenger flight ever to land on the remote island, located in the middle of the Atlantic Ocean. St. Helena’s authorities hope that the new air service from Johannesburg, South Africa will help boost tourism on the island.
Up to now only a boat service every three weeks connected the island with the African continent. It took a ship about 6 days to travel from South Africa. The small island reliesheavily on British aid to survive. St. Helena’s tourism officials say that the new air link will bring 30,000 visitors to the island every year, compared to only 4,000 last year.
The airport cost almost £ 300 m and has been widely criticised as being the most useless airport in the world. Only smaller airplanes can fly to the island because strong winds to not allow large jet planes to take off and land.
Saint Helena is mostly known as the island to which French emperor Napoleon was banned and diedafter he had suffered a defeat at Waterloo. The British overseas territory is only 122 square kilometres large and lies 2000 km off the coast of Africa. It has a population of 4,200 .
Development on the island has been slow. It got its first mobile phone service in 2015 and the first luxury hotel on the island is opening soon. Wildlife and nature on and around the island is why tourists find there way to St. Helena. A Marine Protected Area was established there last year.

Winds and storms in the Atlantic are so strong that wind-powered turbines in the Atlantic Ocean could provide the whole world with clean energy. Energy experts now claim that ocean wind farms can produce three to five times more energy than wind turbines on land. Over water wind speeds are up to 70% higher.
Winds on land create friction because of mountains and buildings. They slow down as they move inwards . In addition, turbines are built closer together, which takes some of the wind speed away .
Winds are especially strong across the northern Atlantic Ocean because of differences in water temperature. When the warm Gulf Stream moves up the North Americancoast it mixes with cold water in the northern Atlantic. This leads to higher storm activity and more winds, especially during the winter months.
Norway’s energy company Statoil has been operating floating wind turbines in the shallow North Sea for over a decade. These are connected via cable to the ocean floor. In order to make them work in the deep sea , however, they must be attached to vertical poles that have massiveweights in the water.
One of the biggest problems that face ocean wind farms is transporting energy from the deep sea to land. Energy companies , like Statoil, are looking for high-wind areas that are closer to shore.
While wind farms on land are becoming more and more common, production costs of running them are becoming lower. In the near future wind energy is expected to become one of the cheapest alternative energy sources .
Europe is the number one wind energy producer at the moment. Every year, about 12 gigawatts of energy are produced by wind power, whereas in America green energy from wind is still in its infancy. If produced more effectively, the solution to the world’s energy problems may lie in ocean wind farms.

Researchers have found that 3 million dollars worth of gold lands in Switzerland’s sewage system every year. After taking a close look at Swiss waste-water treatment plants, they claim that over a hundred pounds of gold and 6,000 pounds of silver are washed away with waste. However, it would be too expensive to remove the gold from the wasted water.
Switzerland is a country that processes and refines gold on a large scale. About 70% of the world’s most precious metal passes through Switzerland in some way or other. Gold is used especially in the country’s watchmaking industry, which dominates the world market.
Other valuable metals pass through the country’ sewage system, but they do not pose an environmental threat.
Most of the refineries lie in the southern canton Ticino, only a short distance from the Italian border.

The second largest diamond ever mined has been sold to a private owner at a public auction in London. The Canadian company Lucara brought the diamond to the surface in Botswana two years ago.
The gem, called Lesedi La Rona, which means “Our Light“, is the size of a tennis ball and has a weight of 1,109 carats. The diamond was bought by a London jeweler for $53 million , the biggest diamond sale in the last one hundred years. In the next few months the new owner of the diamond wants to cut it into several smaller stones.
The only diamond larger than the Botswana diamond was the Cullinan , which was discovered in South Africa in 1905. It was cut into several smaller diamonds, which are today part of the British Crown Jewels.
Lucara tried to sell the diamond last year but did not get the price it wanted, probably because the diamond is extremely difficult to cut. The Canadian mining company is one of the largest in the world and operates diamond mines in Botswana, Zimbabwe, Angola and South Africa.

According to a new report, diesel cars have caused thousands of premature deaths in Europe in the past few years. These deaths could have been avoided if countries had met anti-pollution standards. The recently published paper comes almost two years after the Volkswagen scandal, in which the German car maker was caught cheating on emission tests.
Europe is a continent with about a hundred million diesel-driven vehicles, almost twice as many as in all the other countries of the world combined. Years ago governments and car makers encouraged consumers to buy diesel cars because they were cheaper, used less fuel and produced less carbon dioxide. Many governments also offered tax reductions if people bought diesel cars. What has not been known until now is that diesel cars produce more nitrogen oxides, which may cause lung diseases.
Italy, Germany and France were the countries that recorded the most premature deaths from diesel-polluted vehicles. Especially diesel trucks that drive in denselypopulated areas contribute to the high level of pollution.
The Volkswagen scandal also shown that emission tests are not accurate and that in some cases diesel vehicles emit up to 4 times more substances than they do when tested in a lab.
Since the scandal broke , governments in Europe and elsewhere have been trying to get people to buy more petrol-driven cars. They have become more efficient than diesel vehicles and the difference in prices are not not as high any more.

The world’s longest railway tunnel, the Gotthard Base Tunnel, was opened after many years of construction. Trains can travel at speeds of up to 250 km an hour through the 57 km long tunnel. It took 17 years to complete and cost $12 billion. The engineeringmilestone will bring southern Germany and northern Italy closer together.
The new Gotthard Base Tunnel is also the world’s deepest tunnel, located 2300 metres below Swiss mountain peaks. A total of 2600 workers involved in building the tunnel had to excavate more than 28 million tonnes of rock.
Gottardinoshuttle trains will be running between the two endpoints of the tunnel and make a stop at Sedrun, a mountain station in the middle. 65 passenger and 240 freight trains are expected to travel through the tunnel every day. The Gotthard Base Tunnel will reduce the time it takes trains to pass through the Alps. A journey from Zurich to Milan, for example, will be reduced by an hour.
The new tunnel is part of a larger European transportation project that includes two other tunnels in the Alps. Ultimately, the EU plans a high-speed rail connection between its two majorharbours, Rotterdam and Genoa.
During the course of history the Alps have been a natural barrier to travel. In the past traders and merchants had to use mountain passes to travel from north to south. The first Gotthard rail tunnel opened in 1882, but as time went on it could not handle the growing traffic.
In the 1990s, Swiss citizens approved of a government plan to build a new tunnel. How hard such a construction feat would be soon became obvious . In places where there was hard rock boring was extremely slow. Workers could only advance only about half a metre every day.
The new tunnel is expected to reduce road traffic crossing the Alps as more and more lorries and cargo companies will put their freight on Swiss trains.
