This technology: Energy and the environment have become a keyword energy and their extraction for industrial and household. Prosperity and full employment depend on a sufficient energy supply. On the other hand: each primary energy production environmental impact. Energy and environment: the central theme of the Düsseldorf mass "Envitec with 77," which took stock and presented models of the future. The use of solar energy has come out from the Coporate stage. Already, House, operation halls and swimming pools with solar panels are heated. Although the often cloudy skies over Europe limited the use of solar energy, it remains attractive enough. In Germany alone, 250 solar installations were installed last year.
This glass tile roof is an example of the combined use of Sun, fresh air and a conventional heating system. Even when no sun is shining, the outside air intake via a heat pump for space heating and domestic hot water is sufficient. The oil boiler must only be carried at ambient temperatures below freezing in operation. This so-called "heat pump heating" reduced to 30 percent the oil share in the energy supply of the House. The principle is easy and trouble-free according to the manufacturer. Warm outside air to the compressor is the 6° conducted and heating up the water from 45 then the cooled air is then returned to the outside air or - a vision of the future - with the help of heat exchangers used for air conditioning.
Out of the air, the natural water reserves of the Earth and the earth itself through the system of the heat pump could become energy donors. The future of environmentally-friendly energy production has begun, you will not displace the primary energy sources such as coal and petroleum, but replace in some areas. Manufacturers of solar systems now report supply shortages.
This report: news from yesterday memories in February 1947: what is my young apprentices in training (original sound 1947) a tour through some of the most important professions shows that gradually enters normal railways the problem of the next generation. School and teaching, learning and testing get back their old value. In special apprentice workshops, E.g. the apprentices of the Reichsbahn receive a thorough preparation for their future profession in 3 year training period. The 350 Mason apprentices of a Munich school enjoy lessons in theory and practice. The test is at the end of the apprenticeship. Everywhere offer experienced master can the technical and the small but important tweaks. Here, the candidate as a task needs to build a vault. To produce the daily bread needs to be also learned in a 3 apprenticeship. Here pictures of a journeyman's examination. The bread over the bread and cakes, fine pastries to the salt bar, the aspiring bakers must master all. A small detour to the young artist, in this case to a ballet school. This includes fitness, energy and zeal. Young moves on hands and toes, which wants to become a prima ballerina. Sports training the offspring of miners in the Ruhr area. One of the most important professions for reconstruction is the miner. In practical work, as well as in a 3-4jährigen study the aspiring to the profession of the miner, of Hauer and the Steiger prepares mountain academies. Becoming a miner, has today some advantage, E.g. increased rations. The care of this profession is considered to be especially important, because Germany's future depends on the coal. The next generation on the cusp of the profession. Distribution after passing the exam. Parade of black lucky charms on the chimney of the big city. Yes, to do so, so it returns to fireplaces in airy heights. 100 candidates to the profession are trained in Berlin currently the black man. A profession that has remained constant through the centuries to sweep with a dual task, chimneys and to bring good luck.
This economy: New today professions in 1977. For example, the fisherman's. Seemingly it has changed little in centuries. The catch will be auctioned each morning in the auction halls, in the evening, the ships run out again. The limits to growth but is also fishing already encountered. Many fishing grounds are overfished, the pollution of the seas threatened fish stocks. While politicians at international conferences to delineate fishing areas and set fishing quotas, fishermen use the insights of science and modern technology to adjust their trade to the changed conditions. Next generation of are carefully trained. Each fisherman apprentice on the training ship "Queen Juliana" is trained in Holland. There, he meets including equipment and fishing methods. For the herring fishing is prescribed a 150,Meter network, dragged the 40 metres below the water surface. This helps the depth sounder. This tracking method is long used to encircle herring shoals.
After a few days on the training ship, 14-15 years students are allowed their first own catch on board dragging.
The processing of fish at sea will be taught. Rational and at the same time gentle use of the technical possibilities are now available, so that the fish stock of the seas for the next generations is maintained.
This society: The silent black forest bread are Narrenfreiheit to recognize these days not winter time is here - at least for a few days fool time. Peaceable citizens slip into bizarre masks and costumes and take possession of the city. The "Rottweiler fools jump" is one of the oldest and most famous Carnival customs in South Germany. Be more than 800 years in winter demons expelled with exuberant parades. Creative anxiety once spawned the grotesque masks before ghosts and demons. Today, the original meaning of this creature is blurred. What remains is the desire for the turn, teasing and playing - a contagious lust, which not only locals but also visitors and tourists succumb to the Carnival.
