“Addressing climate change and global warming is more important today than ever before” – Michael Le Messurier, Principal Commercial Manager, RESA

Renewable Energy Solutions Australia (RESA): Whisper-quiet wind power

For centuries the wind has been harnessed as a source of energy. Looking to maximize the potential of this infinite power source, RESA Principal Commercial Manager, Michael Le Messurier, saw an opportunity to champion a wind power design-led revolution.

The challenge

Create a viable and environmentally friendly wind power system.

The solution

Silent, sustainable and superior wind power.

From watching planes to developing wind turbines

As a child, Michael Le Messurier would sit for hours watching planes taking off and land. It was this fascination with the wind together with his passion for renewable energy that inspired him to get involved in the development of the Eco Whisper Turbine.

Le Messurier sees a future in which every house or commercial enterprise has some form of renewable energy. He recognizes the limitations of using fossil fuels and sees the solution as a cumulative collaboration using different renewables where appropriate.

“The Eco Whisper Turbine is virtually silent and has really changed people’s perceptions towards wind turbines in general.”
– Michael Le Messurier, Principal Commercial Manager, RESA

A quiet revolution

Most traditional forms of energy come from non-renewable sources and the production of these types of energy can also be damaging to the environment. Le Messurier came to the renewable energy sector with a desire to make a difference to the world and the environment. Le Messurier and his team were determined to address concerns about noise and the environmental impact of wind turbines in order to ensure scalability – they created the Eco Whisper Turbine to do just that.

Les Messurier explains, “It’s a turbine that follows the wind so it’s always trying to face forward into the wind. Basically the wind turns the blades and it’s all directly connected to a generator. The power from the generator goes through a conversion process and we can either put that energy back into the site, into batteries or it goes back into the grid.” A revolutionary aspect of the Eco Whisper is that it’s virtually silent due to an outer ring placed around the tip of the blades. Le Messurier explains the concept by drawing a parallel to a common desk fan or room fan, “As the speed increases, the noise increases as there’s more air coming off the tip of the blades but that outer ring prevents that from happening.” The Eco Whisper Turbine also has 30 blades rather than the conventional two or three, which gives it the ability to start rotating and generating power with just a slight breeze. All of these factors combine to enable the Eco Whisper Turbine to generate up to 30 percent more power than conventional three-bladed designs.

There were concerns that wind turbines can cause negative health effects and have adverse environmental impacts but Le Messurier says, “The Eco Whisper Turbine really knocks a lot of that on the head. It’s virtually silent, and it’s had no impact on bird life to date and its design is especially unique. It has become something that people like and want to be associated with.”

A design-led revolution principle in action

Massive Collaboration

The Eco Whisper Turbine team used local manufacturers, Austeng in Geelong, and they’ve collaborated with the ICN (Industry Capability Network) and Commercialisation Australia. The team’s chief mechanical engineer utilized Autodesk software to quickly incorporate any changes made to the design following from discussions with the other parties, and the design software simplified and enhanced the collaboration process.
