  • Strom


    From Turbine to Socket

    You realise how important and self-evident electricity has become in our everyday lives only when it is no longer there. At home, household appliances run by electricity would not work anymore. The refrigerator would not cool anymore, the heater would not heat anymore. No washing machine, no telephone, no television, no game consoles – and, of course, we would suddenly be plunged into darkness if the light went out. Even a flashlight would not help because it works with electricity as well even though this electricity does not come from the socket but from a battery. Without electricity we would actually be in the dark.
