Why is the Hydroscrew so effective?
To release the full potential of energy from rivers or hydropower, we use recently adapted technology known as the hydroscrew. Hydroscrew technology builds on previous developments in order to generate energy in a more efficient way – using the entire length of the screw to harness the energy of flowing or falling water.
This represents a major step forward in engineering. The Hydro Screw itself is driven by the flow orflow or fall of the water and rotates in order to generate electricity in what is a very simple and effective physical process. Due to the simplicity of the process and the low stress mechanics of the system you can expect any Hydro Screw installed on your site to enjoy an impressive predicted life span of at least four decades.
The negative minimal environmental impact of using a the hydroscrew technology is very low and this makes it the perfect choice for organisations and private enterprises interested in a more conscientious and eco-friendly ways of providing their premises with continuous greenadequate energy. The adaptation of the Hydro Screw in its current form to low head sites such as rivers and streams has proved highly successful, meaning the technology is available for use much more widely than before.

What is the Archimedes Screw Turbine?
The Archimedes Screw is the name given to a variety of screw pump invented by Archimedes in the 3rd century BC and the physical processes involved in the mechanics of this pump provide the basis for the Archimedes Screw Turbine.
The design for the Archimedes Screw pump involved the application of energy to a screw in order to pump water from low levels to higher levels. The pump has been used successfully for generations. However, only recently has the concept of the screw pump been turned on its head. The mechanics of the Archimedes Screw turbine run in reverse: the fall of water from high levels to low levels turns the screw in order to produce energy.
The implications of this reversal are extremely positive. This form of hydropower provides an effective and inexpensive alternative to environmentally harmful methods of generating energy. It is amazing to think that generators have only been powered by a reversal of the concept of the Archimedes Screw since 1997. Since then, many enterprises have sought to make up lost time with relation to hydropower.

How did Archimedes Screw Hydro Power develop?
It is is often the case that the most impressive modern technologies are the result of applying different interpretations to to previous ideas. The development of the Archimedes Screw in the 3rd century BC had nothing to do with generating energy – rather it was concerned with using energy in order to pump water from low levels to high levels for irrigation.
The Archimedes pump was extraordinarilily successful and it has been used for centuries. However, in recent years the concept that the Archimedes Screw is built on has been re-evaluated. Instead of putting energy in as a means of manipulating the flow of water, modern minds have found a way to use the same basic piece of machinery to use the flow of water to actually generate energy.
The process of capturing energy in this manner is known as Archimedes Screw hydro power or hydroelectric power. ... It is cost-effective, low maintenance and eco-friendly and it is currently being taken up by a host of businesses and private clients with access to running water, including low head sitess with low flow rates such aslike rural streams. This form of hydro power offers a great deal of potential on for industrial, commercial and domestic sites.

Hydropower
Hydropower is central to the modern search for effective sources of renewable energy. The primary aims of hydro power techniques areis to generate clean, green renewable energy and free sites from a dependency on energy sourced from fossil fuels which can arebe extremely expensive and which haves a deleterious damaging impact on the environment.
We Hallidays Hydropower specialise in engineering hydro power solutions to suit the specific requirements of each site we work on. Our designers and engineers are experts in their field and they are dedicated to helping you incorporate hydropower into your operations.
Our team of specialists are experienced in working on contemporary structures as well as historical sites where hydro power has been identified as an important form of modernisation. We also exercise the utmost sensitivity and professionalism when working in historical settings in order to preserve the character and integrity of the site.
