KU-AN was installed in July 2021 to verify the sustainability and stability of Micropower Collection technology. KU-AN uses 1,500 wooden collection cells filled with food compost and soil to supply power to 800 12V LED lights installed indoors. It also records power logs and environmental data such as temperature and humidity, enabling observation of the electrical characteristics of Micropower Collection under various environmental conditions.

Designed with the concept of a “floating space of light,” KU-AN creates a visual effect in which LED reflections on glass resemble an endless starry sky when illuminated. In addition, the electricity generated by KU-AN can be stored, allowing adjustable brightness and the potential use of the stored power as an emergency off-grid energy source.

Testing improvements in Micropower Collection performance and sustained energy harvesting.
Verifying the interoperability of Micropower Collection with various advanced IoT systems.

Power is generated using wooden cells filled with food compost and soil.
The electricity harvested by the wooden cells is stored in a custom-developed storage unit and can be used as needed.

Developing locally sourced, sustainable power using soil and compost.
Providing emergency power support during disasters.
