Conceptual design to persuade people to save electricity energy by using the metaphor of pot and constructing the cognitive concept of "daily electricity consumption" to users' mind.

It indicates how much and when energy is being used and thus gives users the information they need to control and reduce their electricity consumption.

+ Use the metaphor of pot to indicate electricity containing and saving

+ Visualize invisible electronics runing in order to remind people the invisible consuming.  

+ Borrow the concept of clock to suggest user how much energy one has used per day. Similar to framing the endless time resource into "day. hour, minute" units, I frame the "unlimited" electricity resource into units to build a daily using concept in people's mind.
