Spherical wind turbine small generator

What is a home energy spherical turbine?

Home Energy has developed a unique concept, that entails that energy is yielded from wind through a spherical turbine: the Energy Ball. The Energy Ball offers the following benefits above a traditional propeller powered wind turbine: • No noise disturbance; the sound of the wind turbines is caused by the airflow at the end of the propellers.

Why do wind turbines have a spherical design?

• No noise disturbance; the sound of the wind turbines is caused by the airflow at the end of the propellers. Because of the spherical design of the Energy Ball it has no such ends, causing it to be silent. • Higher efficiency; the aerodynamic design of the Energy Ball ensures a higher efficiency in the yield of energy.

How do small wind energy systems work?

Small wind energy systems can be connected to the electricity distribution system. A grid-connected wind turbine can reduce your consumption of utility-supplied electricity for lighting, appliances, and electric heat. If the turbine cannot deliver the amount of energy you need, the utility makes up the difference.

What is energy ball wind turbine?

Energy ball wind turbine, known as Venturi wind turbine, has untraditional blades’ shape and special aerodynamic behavior that creates a venturi effect on the air stream passing through its aspherical shape.

How much power does a small wind turbine generate?

Small wind turbines can have a generating capacity in the range of 0.3–100 kW, though the amount of power they generate depends on the wind speed. A small turbine typically needs a wind speed of 3 m/s at the height of the turbine, which makes them ideal for many applications. 1

Why do small-scale wind turbines need a gearbox?

Small-scale wind turbines (SSWTs) operate with relatively high rotational speed due to the small radius so that there is no need for a gearbox. This approach reduces the cost, maintenance, and improves the reliability and efficiency at low wind speed operation.
