Working prototype

Movie clip: Demonstration of the prototype silent wind turbine

Click here to view our promotional video clip (48 seconds; 4.9MB; WMV format).

Movie clip: New blade design

This movie clip shows just how much more efficient the new blades are compared to the previous design. The wind speed was very low when we took this movie: just 1.7 m/s! An electrical current was being generated, even at that low speed.

(The movie clip is 19 seconds; 1.2MB, WMV format.)

Fully-functional prototype

As a result of high levels of commercial demand, we’re currently working on a micro-turbine with a 500W output, though in the future other sizes of turbine would also be developed as the technology is scaleable.

Right: This is a fully-functional prototype of the Luethi Enterprises silent vertical axis wind turbine, measuring 1.5 m tall, with a diameter of 90 cm. It weighs approximately 50kg (without the mast).

This particular prototype has been sited on a farm in Nottinghamshire for three years, powering an LED streetlight non-stop. The wind turbine has survived numerous storms without sustaining any damage.

Below: The turbine is mounted on a trailer ready to travel anywhere for demonstration.

Below: The new blades are aesthetically pleasing - as well as extremely efficient.

Below: field testing allowed us to refine the blade shapes and configurations further still. This photograph shows the latest prototype of the 500W DC Silent Wind Turbine.

Below: demand for a cheap wind turbine for developing countries led us to create a 250W Barrel Turbine:
