Water Turbines

If you have a significant water flow on your property you may be able to generate power from it with one of our wide range of impulse and reaction turbines.

A "significant flow" can be anything from a small stream with a large drop to a large, slow-flowing body of water to a large river with a steep fall. 

Obviously, a large amount of water falling from a great height has the potential to produce a large amount of electricity but even a small stream can provide most or all the needs of a single house. In this case we store the power in a battery bank and then feed the output through an inverter to give high quality 230 volt AC power.

 

The system is flexible, allowing you to modify it at any time by, say, adding a solar panel or back-up diesel generator.
Some people run a hybrid wind / water system using a wind turbine in parallel with a water turbine.
Twin micro-hydro power turbines.  Each turbine has two 3-phase delta windings providing up to 3kWatts of power.  These turbines charge a battery bank (48V) to provide power to a set of inverters, which in turn provide power to a house as and when it's needed
Should the turbine just be needed to provide heating then there is no need to go to the expense of having batteries and an inverter.

Once we know your requirements and the potential of your water resource we can quote you for a system tailor made to your needs.


The Stream Engine:

The Stream Engine is designed for use in battery-based power systems, with electricity generated at a steady rate, and stored in batteries for use at higher rates than is generated

The Stream Engine operates at heads of about 2m (6 feet) and upwards. The water passes through a nozzle, where it accelerates, strikes the bronze turgo wheel, and turns the generator shaft. The generator is a robust permanent magnet alternator, efficient and highly tolerant of overspeeding.
During times of low demand, power is stored. An inverter is
Used when residential power is desired. Water from a stream is channelled into a pipeline to gain enough head (the vertical distance the water falls) to power the system

Calculate your water flow:

One method of measuring water flow is by the use of a notched weir. This is usually a piece of plywood with an accurately cut rectangular notch of an appropriate size to allow all the water to flow through. If certain steps are followed carefully the flow of the stream can be calculated fairly precisely.
