China needs more water. So it’s building a rain-making network three times the size of Spain

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.

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.

“[So far,] more than 500 burners have been deployed on alpine slopes in Tibet, Xinjiang and other areas for experimental use. The data we have collected show very promising results,” a researcher working on the system told the South China Morning Post.

The system is being developed by the state-owned China Aerospace Science and Technology Corporation – a major space and defence contractor that is also leading other ambitious national projects, including lunar exploration and the construction of China’s space station.

  1. Why waste money buliding useless, far too expensive, and space-wasting machines, when all they need do is hire a tribal Originee rainmaker from Australia?
    I have witnessed these people make rain INSIDE a house, INSIDE a motor vehicle, and OUTSIDE, causing great floods….only because they were very ANGRY.
    Brisbane, was a typical example, labelled by ‘officials’, and the courts, as “AN ACT OF GOD”.

    However, if conducted with a positive attitude in mind, these rainmakers can start, and stop, making rainwater in your area within 30 minutes!
    Interested?
    Also, if that’s not what you want….ring NOEL ORCHARD! The US Navy does!

  2. “10s of thousands of solid fuel burning (wood, coal…) chambers…”

    Way to go china, like you don’t already have filthy air to rival that of mexico and india.
