The Liam F1 Urban Wind Turbine, developed by Dutch tech firm The Archimedes, aims to bring urban household wind turbines a more common sight.

The 75-kg, 1.5-meter wide Liam F1 Urban Wind Turbine doesn't have the shape of a typical turbine. It instead draws on the form of nautilus shells and the screw pump invented by ancient Greek scientist Archimedes. This shape supposedly minimizes mechanical resistance, allowing the turbine to spin freely and operate quietly. The design also ensures that the contraption is always pointed into the wind for maximum efficiency.

The Liam F1 Urban Wind Turbine is capable of generating an average of 1,500 Kilowatt-hours of energy a year at wind speeds of 5 meters per second. This is enough to cover half the power consumption needs of a typical household.
