Archimedes Screw Generator produces Electricity at low-head Hydro sites

A centuries-old technology is being used today to generate electricity. The design of the Archimedes screw is attributed to Archimedes of Syracuse in the 3rd century BC. Originally, this technology was used to lift water up an incline. Recently, scientists determined that it is possible to produce electricity by letting water drop through the screw.

 

The screw generator consists of a central shaft with a helical blade, like a screw. Allowing water to flow downward through the screw causes it to rotate. This rotation can be used to produce electricity using a generator. The screw generator is safe for fish to pass through and can serve as a fish ladder. The screw generator can be used in locations with relatively low head (up to 10 meters) and requires minimal maintenance.

 

There are many companies that manufacture the Archimedes screw generator. Units are available in capacities up to 500 kW.

 

The Archimedes hydro screw  is being used in several applications in UK and Europe,due to its fish friendly qualities .

In May 2010, a contract was awarded to supply and install four Archimedes screw generators at a training camp location for the London 2012 Olympic Games. This work is part of an ongoing upgrade of the Tees Barrage whitewater course. The screws will pump water to provide the course. When not needed, the screws can use the river water to generate electricity.
