Greetings and vision : Wind, sunlight, water, energy in nature and human life. Harmonious mini home appliances Our Natural Energy Lab was created in July 2018, and we would like to develop and distribute various products using solar cells, fuel cells, and water electrolysis devices. As the first challenges, we developed Solar Cell Independent Power Vehicle Air Purifier (Sol-leaf) and Automobile Fragrance Diffuser (Aroma-wind) Second, we will apply a tube-type solid polymer water electrolysis device (2010 patent registration) that can produce hydrogen and oxygen to various products. We will do our best to apply eco-friendly energy sources to small home appliances and help people's health with them. Business Plan 1. New type air purifier for automobiles. We will try to develop a satisfying product that can give the driver freshness when the door is opened by developing a portable and wireless independent air purifier to truly implement air cleaning capability for the driver. The Natural Energy Lab will constantly research and develop to add functions that help consumers' health and improve performance. 2. Small portable oxygen supply. We will do our best to solve the difficulties of consumers who have been uncomfortable with noise , vibration and heavy bodies by developing a portable oxygen supply device with a tube-type solid polymer membrane. 3. Light tube type fuel cell power box (for drones) We are developing a fuel cell power box that can dramatically increase power supply time and drone operation time, which are disadvantages of secondary battery power boxes. We will make a light and high-efficiency power box using the patented tube-type fuel cell, and do our best to ensure consumer satisfaction with the power supply for long-distance drones combined with compressed hydrogen containers and hydrogen storage alloy containers.
