Passage 2

Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off and on again when you return. A sensor will detect the presence of a human and turn the systems on, and when the humans leave it will turn them off again.
The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will detect faulty electrical appliances, isolate them so that they cannot harm anyone, and then warn you that they need repair. They will detect fire and if you are out of the house, the computer will call the firemen. It will also call the police should the sensors detect an intruder. You will open the door using your personal card---the one you use for shopping---maybe using a number known only to you.
