The Spark Lamp idea by Beverly Ng is an LED lamp that is flipped over during the day to recharge itself via solar power. But that’s not all! Inside the lamp is an integrated WiFi which wirelessly gets your home’s power usage information. When you turn the lamp on, it briefly changes colors and flashes to tell you what your home’s power consumption is at that moment. The entire lamp sort of looks like a houseplant and is itself a metaphor for how plants receive sunlight and convert them to energy via photosynthesis. The idea is to make the owner more aware of their own energy usage. Interesting concept.
