KU-AN was installed in July 2021 to evaluate the sustainability and stability of MPC (Micropower Collection) technology. It uses 1,500 wooden collection cells filled with soil and compost to supply power to 800 indoor 12V LED lights. KU-AN also records power logs and environmental data such as temperature and humidity, enabling analysis of MPC’s electric behavior under various environmental conditions.
Designed as a “floating space of light”, KU-AN creates a visual effect where LED reflections on glass resemble an endless starry sky. It also can be stored for potential emergency off-grid use, allowing for adjustable brightness.

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

Power is collected using wooden cells filled with soil and food compost.
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.
