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.

The Egyptian Book of the Dead
The notions described in the texts and pictures of the Book of the Dead are central to the ancient Egyptian belief in an afterlife – the belief in resurrection and life after death. In order to be granted passage to the “Realm of the Blessed”, the deceased first have to justify themselves before the Court of Death and give account that they have led their lives according to the laws of Maat – the order of the universe and justice. The Book of the Dead lists the names of the judges at the Court of Death, who the dead must appeal to and convince of their innocence. Further, it contains a plethora of magical texts for the protection of the deceased and describes the places in the underworld. These texts were inscribed on papyri, coffins and numerous burial objects like canopic jars, uschebtis or mummy masks so that they were available to the deceased at any time. After all, they describe their transformation from mortals to glorified god-like beings who would live eternally.

Aluminium I
In the modern world, we encounter aluminium at every turn. This is due to the particular properties of the metal. Increasingly, aluminium is about to edge iron and steel out of engineering, as aluminium allows energy-saving lightweight construction of aircraft and vehicles of all kind. Aluminium is weather-resistant, does not rust and is therefore well suited as building material for house facades, window frames or simply for all parts that are exposed to wind and weather. At the same time, aluminium has a noble-looking surface recommending it as material for interior design.
