Instinctively, this sounds unwise in the same way that a lot of big science ideas in the 1960s sounded foolish years ago, e.g. using atomic weapons to build canals https://en.wikipedia.org/wiki/Project_Plowshare https://en.wikipedia.org/wiki/Project_Plowshare It also sounds like it faces the same resource allocation problem that oil reservoirs across political boundaries face, except the reservoir is in the sky and constantly being recharged. So who will play the role of the Texas Railroad Commission for clouds? https://en.wikipedia.org/wiki/Railroad_Commission_of_Texas https://en.wikipedia.org/wiki/Railroad_Commission_of_Texas Silly ideas of big science died in the West in part because of the sort of political resistance that current China seems determined to weaken/squash. This makes China’s involvement in these schemes more problematic. Who would have stopped Mao from building canals with H-bombs? Who would stop Xi? Still, a lot of neat science and modeling work to be done to evaluate the ideas...
