The Greeks gave us so many wonderful old concepts — Archimedes’ screw, the Olympic Games, democracy — that I figured a new Greek concept could be a real game-changer.

Balls ride up Archimedes’ screw, roll across an aerial track, race through a table top maze and bounce across the inside of a piano, hitting notes as they strike the wires.

A giant Archimedes screw has been lowered into place as part of a Lancashire community project to generate power.

Archimedes’ screw systems have already been implemented throughout the UK, as pictured, and Europe.

Now, the development process is underway as the company begins to woo potential customers with the Archimedes screw system and coordinates construction to dams’ specific needs.
