Royal Patent - Chaipattana Low Speed Aerator

His Majesty King Bhumibol Adulyadej combined his keen interest in mechanisms, motors, and vehicles and his strong desire to help the Thai people by cleaning the increasingly polluted waters of his country by developing water aeration devices. In 1993, His Majesty became the world's first sitting monarch to be granted a patent for an aerator used in waterway treatment. The device, referred to as "Chaipattana Low Speed Aerator", which is a paddle-wheel machine attached to a floating buoy that adds oxygen to water though the moving of the water with the paddle scoops. The Chaipattana Low Speed Aerator can be seen in many of the waterways in Thailand. The photos in this blog are from Lumpini Park in Downtown Bangkok. ​The monument shown in the photo to the right is a tribute to the Thai King and his efforts in developing this important device.
