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.

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.
