ROTTERDAM, Netherlands—A Dutch company has launched a new domestic-use wind turbine that it claims “hardly produces sound” and has a yield more than three times that of traditional household turbines.

According to The Archimedes, a Rotterdam, Netherlands-based research and development firm, its new Liam F1 urban wind turbine has a yield of 80 per cent of the maximum feasible, compared to an average of 25 per cent from current generation turbines.

Designed with a screw form, the Liam F1 generates an average of 1,500 kWh of energy or about half of the power consumption of the average European household.

When used in conjunction with roof-mounted solar panels, the company claims a household could be totally self-sufficient.

“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,” engineer Richard Ruijtenbeek said in a statement.

By combining the form of a nautilus shell, the theories of Greek scientist Archimedes and his own mathematics, inventor Marinus Mieremet created the Liam F1 to have little resistance, making it virtually soundless.

What’s more, because of its screw-form, the Liam F1 automatically aims itself to be in line with the optimal position of the wind.

The company said it has already sold 7,000 turbines in 14 countries and has started developing smaller turbines for use on boats and lamp posts and in water.
