Silent rooftop wind turbines could generate half of a household’s energy needs

Silent wind turbines have been invented to revolutionize the home.
A Dutch company has created a soundless wind turbine that is set to change the way renewable energy in the home is used.
Wind turbines of all sizes have their supporters, and indeed their enemies. Despite being hailed as eye-sores by many, when used on a small scale, the main complaint about them has been their noisiness.
The home wind turbines of the past have been exceedingly noisy, putting many people off and rendering them unusable for those that had them installed.

But this is set to be a thing of the past, with Dutch start-up The Archimedes who have designed a noiseless turbine, perfect for any home.
Their Liam F1 turbine has been built in such a way that it can produce 1,500 kWh of energy per year at wind speeds of just 5m/s and is virtually silent when in use.
The designers are so happy with their product, the estimate than when used together with solar panels, this would be enough for a regular household to produce enough energy to live ‘off-grid’ – a goal for any environmentally conscious family.

Richard Ruijenbeek, CEO of The Archimedes project says:
“When there is wind you use the energy produced by the wind turbine; when the sun is shining you use the solar cells to produce the energy,”
Just looking at the shape of the design of the blades, these don’t look like the normal image of a wind turbine. The blades are more shapely, inspired by the Nautilus shell.

This clever shape allows the turbine to harness far more power than previous designs, inventor Marinus Mieremet says it can harness around 80% of the wind power at any given time.
He says:
“Even when the wind is blowing at an angle of 60 degrees into the rotor, it will start to spin. We do not require expensive software: because of its conical shape, the wind turbine yaws itself automatically into the optimal wind direction.”
