Beavers. Beavers are the engineers of the rodent world. They fell trees by gnawing through their trunks, then use the branches to dam streams. The dams create a pond, in the middle of which the beaver family constructs an island made of more branches.eavers. Beavers are the engineers of the rodent world.

Dams produce hydroelectricity, and the step to creat that, is very easy. What you need to build a dam is a river with a large drop in elevation-such as a waterfall.The dam stores lots of water behind it in it's reservoir-or a lake-type thing as a result of decreased water flow.Near the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.In the tunnel, the water flows down a large drop-called a penstock-and gravity causes it to gain speed.ear the bottom of the dam, there is a water intake controler, that only allows certain amounts of water to flow into a tunnel.
