A wind turbine that spins in a spherical formation increases efficiency and reduces noise, according to its Dutch developer, Home Energy.
The Energy Ball replaces the traditional rotors of a wind turbine with an egg whisk-shaped structure designed to funnel wind within the turbine’s blades.
Erik Aurik, Home Energy marketing manager, said the technology works on the Venturi effect, which is usually associated with the drop in pressure that results when a gas or fluid flows through a constricted space at speed.
The spherical ball uses that principle by constricting the wind, so causing the pressure inside the ball to drop. The low pressure means the air flowing around the ball is sucked in and this helps turn the rotor blades.
