China, in Search of Water, is Building a Rain-Making Network Three Times the Size of Spain (scmp.com)

China is testing cutting-edge defence technology to develop a powerful yet relatively low-cost weather modification system to bring substantially more rain to the Tibetan plateau, Asia's biggest freshwater reserve. From a report: The system, which involves an enormous network of fuel-burning chambers installed high up on the Tibetan mountains, could increase rainfall in the region by up to 10 billion cubic metres a year -- about 7 per cent of China's total water consumption -- according to researchers involved in the project. Tens of thousands of chambers will be built at selected locations across the Tibetan plateau to produce rainfall over a total area of about 1.6 million square kilometres (620,000 square miles), or three times the size of Spain. It will be the world's biggest such project.

The chambers burn solid fuel to produce silver iodide, a cloud-seeding agent with a crystalline structure much like ice. The chambers stand on steep mountain ridges facing the moist monsoon from south Asia. As wind hits the mountain, it produces an upward draft and sweeps the particles into the clouds to induce rain and snow.

    Yeah, they'll use up all the water before it rains over the pacific ocean. Oh, noes, the Pacific Ocean will dry up! AAaaaaaaa!

    You so smarter than everyone. No they no think that. But you see big idea. Better than many experts. Just one person knows most. I vote you me come over border next week. I network engineer I can work. Make space me will better deal for company.
