🇹🇭 Do you know the ever-loved late Thai king, King Bhumibol Adulyadej has numerous patents under his name and was even designated “The Father of Thai Invention”?

🚩 One of the possibly best-known innovation would be the Chaipattana Aerator. The Chaipattana Aerator is a floating buoy that rotates slowly to pump oxygen into wastewater. The low-cost, simple mechanical device effectively treated polluted water while oxygenates water in ponds for breeding aquatic animals. It was first developed when Thailand faced severe water pollution problems during the 1990s. The Chaipattana Aerator Model RX-2 was granted a patent in 1993 and was the first patent in the world given to a reigning monarch.
