Right now there are 10,000 cubic kilometres of water behind dam walls - five times the volume in the planet's rivers. The weight is so great it triggers earthquakes, and geophysicists estimate that the redistribution of weight from reservoirs may be having a measurable impact on the speed the earth rotates, the tilt of its axis and the shape of the gravitational field. But there's something the dammers haven't been telling you: dams die. And when they do, all hell breaks loose.
We're going to get their stinking dam. We've got secret plans. We're going to set up a laser beam below the dam, drill a tiny hole through the base of it.
