On November 14 the same year, His Majesty donated his private funds to launch the Royal Rainmaking Project, and he devoted a great deal of time and energy to develop rainmaking technology. Later, he entrusted M.R. Debariddhi Devakula, an expert in agricultural engineering at the Ministry of Agriculture and Cooperatives, to undertake research into rainmaking. M.R. Debariddhi conducted intensive research and experimentation over several years from various models applied by various countries, such as the United States, Australia, and Israel. After initial research, the first practical experiment took place over a mountain barrier at Khao Yai National Park in Nakhon Ratchasima Province in July 1969, supervised by His Majesty.
