News bulletin: New blade shape promises extra efficiency – 10 November 2008

The new, curved blades perform even more efficiently in low wind speeds than our previous design. In fact, we estimate that the increase in performance could be as much as 20%.

Made from fibreglass, the new blades are strong, durable and relatively lightweight. Luethi Enterprises Ltd has applied for a global patent to protect the design.

The new blades are aesthetically pleasing - as well as extremely efficient.	The blades are curved on both planes.

Movie clip: New blade design – 10 November 2008

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 motion is converted into power by a bespoke generator designed and manufactured solely for Luethi Enterprises Ltd by Lafert Motors. It's designed to give 1.5kW of power. The generator's performance is being monitored: testing will identify suitability for different sites.
