China is running out of room for its growing urban population. This amazing design--an entire prefab city that floats on water--could magically create more space.

As China prepares to squeeze in 350 million new urban residents over the new decade, the government will pave 5 billion square meters of new roads and build hundreds of new cities and towns. And as available land space gets smaller and smaller--especially near the bigger metropolitan regions where people really want to live--China may also start building cities on water.
