All technological systems exist to perform something, and can be described with four major functions of technological systems: Transform, transport, store and control. This film will introduce you to the function of transporting. People have always had the need to move objects or themselves from one place to another, first by simple boats and rafts, but thanks to advanced technology we can now travel in airplanes through the air and even up to space. In this film you will learn how materials, people, information and energy have been transported historically and how modern transportation systems have developed over time.
