Hydrological Cycle

Water is the source of life because life on our Earth originated in, more precisely, under the water. Water is essential for animals, plants and for us humans. Without water survival is impossible. Pure water is transparent, it smells and tastes of nothing. But where does the water come from? Where does it flow? And what happens to the water we do not use?

Dead Angle

Not only lorries have a dead angle. Other big vehicles such as buses or motor homes, even perfectly normal cars have a dead angle, that means an area where a driver might overlook a cyclist or pedestrian when turning corners. New technology is meant to help prevent accidents between cyclists and lorries. For example, sensors are often attached to lorries nowadays.

The Otto Engine

This DVD offers an insight into the historical birth of the Otto engine and also describes its latest version – the hybrid engine. In addition, other engines of the future are covered. The life and achievements of Nikolaus August Otto are dis- cussed, with all his successes and failures, from his first en- gineering attempts when reconstructing the Lenoir engine to the presentation of the “atmospheric gas engine” on the Paris World Fair through to his cooperation with Gottlieb Daimler and Wilhelm Maybach. The mode of operation of the Otto engine is explained to the pupils in detail, also with the help of a variety of animations and diagrams. The DVD goes into the four strokes of intake, compression, power and exhaust as well as the Otto engine as energy converter. Crude oil is one of our most important sources of energy. Besides outlining the evolution and processing of crude oil into fuel, this DVD puts emphasis on the increasing shortage of global crude oil resources. Alternative propulsion sources like hybrid engines as well as hydrogen-fuelled or gas-fuelled vehicles offer an environmental-friendly vision for the automobile’s future in times of global climate change.

Source of Energy

Energy determines our lives. Without energy, plants, animals and humans would not be able to live. Without energy, there would be no movement. But what is energy? Where does it come from and how is it used – yesterday, today, tomorrow? The DVD provides an illustrative introduction into the highly topical issue of energy. Starting with the human perception, it leads us to the cosmic primal source, the huge fusion power plant above our heads – to the sun. In doing so, it explains how energy reaches the Earth and is used here in different ways by plants, animals and humans. The physics part clears up the terms work, power and degree of efficiency. The DVD shows what conversion losses occur in the process from primary energy to useful energy, of course including the clarification that energy can neither be generated nor lost in a physical sense. The ecological, economic and social sustainability is discussed. This way, it is made clear that only Renewable Energy – thus energy from the Sun – can secure our future.
