The Power of Fish

They do keep coming, don't they? One new and wild invention after another, with much promise to change the world. This one from the Daily Telegraph.co.uk claims to be a device when placed in water that can generate electricity more efficiently, less disruptively and with smaller water flow requirements than turbines and dams.

According to the article:

The new device, which has been inspired by the way fish swim, consists of a system of cylinders positioned horizontal to the water flow and attached to springs.

As water flows past, the cylinder creates vortices, which push and pull the cylinder up and down. The mechanical energy in the vibrations is then converted into electricity.

The technology was developed through funding from the US government. There is a prototype being dispensed currently in the Detroit River, which flows at less than 2 knots.
