They set it as a goal to turn the Ryuwon Footwear Factory into an icon and standard one and have solved sci-tech problems together with employees of the factory.

A stable and highly efficient solar generation system was established with solar panels covering roofs of several buildings in the factory and its generating capacity reaches several hundreds kW.

The scientists also made a solar collector to build a hot-water supply system based on solar water-heater in the factory.

Thanks to their efforts, a soilless solar-heat greenhouse with an area of over 300 square meters took its shape, equipped with drip irrigation system, automatic system for supplying nutrient solutions and comprehensive measurement system.
