The uptake of residential wind turbines in South Africa has been slow but globally the use of wind turbines in households is becoming more and more popular. The main gripe is the lack of wind consistency for sustained power production and the noise factor (which can get pretty annoying).
Trust the Dutch, who have a reputation of producing energy from wind to come up with a high performing silent wind turbine. The unique product has been developed by Dutch renewable energy start-up, The Archimedes. Their Liam F1 turbine is a game changer.
It comprises of three circular blades which are wrapped around one another and then expanded. This creates a three-dimensional conical turbine, similar to elongated shells found on the beach. The special design ensures that wind is drawn into the turbine. The average yield is many times higher compared to a normal urban windmill propeller.
The Liam F1 will be able to generate 1,500 kWh of energy per year and can be installed on the rooftop of a house. The system can also be integrated with a solar power system and battery bank to provide base load power at all times of the day. A Household could practically be off grid with such a hybrid system.
Hopefully it will be available for the African market soon.
