Seattle Wind Energy
Energy Ball V100

This beautiful and low-noise turbine is being characterized by the six curved rotor blades which are attached to the rotor hub with both ends. When the Energy Ball® rotor turns it resembles a sphere, and as a distinct feature the wind blows parallel to the rotor hub through the rotor. This wind flow direction (flow pattern) forms a key contrast with classic sphere shaped Darrieus turbines, whereby the wind hits the blades perpendicular to the rotor shaft or rotor hub.

Due to the unusual and exceptional aerodynamics characteristics of the Energy Ball®, it creates a wind flow pattern that converges first and is then accelerated through the rotor, resembling the rapids in a river (the so-called Venturi effect). This translates into a higher aerodynamic efficiency compared to conventional wind turbine designs.

The Energy Ball® starts producing electric energy as from very low wind speeds and has therefore a very low standstill time. The unique design makes that an electricity producing Energy Ball® is virtually transparent.

Energy Ball V100

The Energy Ball® V200 is an artistic spherical wind turbine with 5 rotor blades and a diameter of 1.98 m which you can use to produce some of your own electricity supply soundlessly. We deliver the complete Energy Ball® package and then install it for you on a mast reaching 12 or 15m in height.

The Energy Ball® V200 also comes with a WindPower Inverter. This converts the electrical energy generated by the Energy Ball® V200 into electricity with a suitable specification for supplying to the mains. (230 Vac, 50 HZ). The WindPower Inverter is connected to a distribution circuit in your electric installation. You can start to use the electricity which has been generated immediately. If you use less energy then the Energy Ball® will deliver to the grid, which immediately results in negative measurement of your grid electricity meter.

The Energy Ball® V200 supplies the maximum amount of power at wind speeds of 19 m/s (wind-force 8 to 9 on Beaufort scale). The Energy Ball® V200 can produce a maximum of 2500 W (see specifications). This maximum power is not supplied to the mains, but rather the power supplied by the generator. If the generator supplies maximum power, this is supplied directly to the mains by the WindPower Inverter 2250 W at 230 Vac and 50 Hz (see Power Curve Energy Ball® V200).

The Energy Ball® V200 can produce an output at the mains of between 240 kWh and more than 2000 kWh each year, with a respective wind regime in the installation location of between 4.0 and 7.5 m/s. This will occur as long as the Energy Ball® V200 has been installed free of surrounding obstacles and attached to a mast which is 15 m high.
