The Archimedes Screw Company
The Archimedes Screw Company (TASC) has designed and built a revolutionary new Hydroelectric Turbine based on the Archimedes Screw principles. It is a fish friendly, efficient device for converting the potential energy in water to electricity.
The TASC turbine is made from reinforced plastic and is suited to smaller, domestic sites producing less than 15kw. The Turbine is designed and manufactured in UK and is easily transported and installed with minimal construction works. There are Archimedes Screw Turbines currently available in the market, but these are made from metal and are thus expensive to manufacture, transport and install. They are suited to large scale sites where you might hope to generate more than 50Kw. The Archimedes Screw Turbine is the turbine of choice of the Environment Agency, due to its low impact on the environment.
