Hybrid Drives
Technology of the Future
When Lena goes through the city centre by car, she has to be particularly careful, because her car is almost inaudible and therefore pedestrians often hear it just in the nick of time. For in the city centre, her car is powered by electricity. The power is provided by a strong battery in the boot.
But as soon as the destination is located far away, Lena switches to petrol operation. Then the car is powered by a normal combustion engine. The fuel comes from the tank – just like with all other cars. Depending upon when and where the car travels, it uses different engines and different types of energy in doing so. That is why the car is also called a hybrid vehicle. Hybrid means something like “mixed”.
This may also refer to an e-bike, which Lena has in her garage as well. It combines electric energy from the battery with energy from muscle power.

Seal of approval
Quality seals such as the "Bio-Siegel", "Blauer Engel", "Stiftung Warentest" and up to 1,000 other seals represent characteristics such as sustainability, health or safety with regard to a product, a service or even a company.
Product Piracy
Counterfeiting takes place in almost all economic sectors – textiles, watches, car parts, machine parts, tools, accessories, software and medicines. Some counterfeits are easy to recognise, others are so well-executed that even experts have difficulty distinguishing between original and imitation. This DVD covers the development of a product from idea to manufacture. Once a product has become a trademark, product pirates appear on the scene.
Ceramic
Ceramics are indispensable in our everyday lives. We eat from ceramic plates, drink from ceramic cups, use tiled ceramic bathrooms. But how is ceramic manufactured? The film reveals the secrets of this fascinating material! We get to know more about the beginnings of ceramic in the Old World of Egypt and Mesopotamia, about Greece, China and Rome. We gain interesting insights into the valuable earthenware and are also shown the exquisite further development of the "white gold". Today this versatile material is irreplaceable in industry, too. Whether in space or as an easily compatible substitute in medicine, ceramic is applied in many places.
