Can pointing giant loudspeakers to the sky help regions recover from a drought? The answer may be yes.
A new study out of Tsinghua University in Beijing found that sending powerful, low-frequency sound waves into the sky may have triggered an increase in rainfall on the Tibetan Plateau.
The researchers said they recorded increases in rainfall of up to 17% by pointing a giant loudspeaker at the sky.
The sound waves also appear to be safe for the environment, but scientists said the experiment would need to be replicated many times to confirm if the technology works.
The team led by Professor Wang Guangqian from the university’s State Key Laboratory of Hydro-science and Engineering, said i
