Automatically following the sun and directing light to an area of your choice.
Some people prefer well lighted rooms. But that is not always possible. Obviously, it would be insane to spend electricity during the day by having the lights turned on. Nevertheless, all those seeking plenty of light can now buy Lucy (produced by the startup company Solenica). This is a smart mirror that follows the sun during the day and casts light to a predefined area, i.e. precisely where you have directed it. It is best to direct it at a bright ceiling, which then disperses the light throughout the room.
Lucy measures 30 centimetres in diameter and weighs 2.5 kilograms. It can be used both outdoors as well as indoors. Notably, it need not be connected to the mains, but is charged by solar energy allowing it to follow the sun.
Lucy is enclosed with an application advising you on its usage and calculating the reduced carbon footprint achieved by turning off an incandescent lamp and replacing it with natural daylight.
The price of the smart mirror is $300.
