At this moment we do not have sufficient data of installed Airturb's to give an answer to this question. When more Airturb's are installed and monitored we will have access to more data about power generation and loation specifications. For this to happen on a large scale we need innovaters and early-adopters to create these Airturb data points. Until then we can only provide the theoretical data from our calculations and available databases.

The Maximum power output of the Airturb Model One system is 420 Watts. This is the total of the 300 Watt capacity from the generator and 120 Watt capacity from the solar panels.

How much the total energy production of the Airturb Model One system will be is largely dependant on the location it is installed. The wind speed is very different on every location and cannot be predicted precisely. There is a powercurve of the generator and the translation of this curve. However, this powercurve is a statement of the possible energy production when the windspeed is constant for 24 hours a day and 365 days a year. This is not a reflection of the reality but merely an informative powerchart of the potential energy production of the Airturb Model One system.

The powercurve for the Airturb Model One system is based on theoretical calculations. These calculations are based on data provided by Royal Netherlands Meteorological Institute (abbreviated: KNMI).

In this report, the Netherlands is divided into three wind areas and thus a fundamental value for the basic wind speed:

➢ Wind region 1: Coastal region and open waters

➢ Wind region 2: River deltas and coastal hinterland

➢ Wind region 3: Inland

Each wind area is divided into terrain categories.

• Terrain category I: Coastal area

• Terrain category II: Unbuilt

• Terrain category III: Built

Based on the "load thrusts" and "load speeds" we are able to theoretically calculate the average windspeed in the above mentioned areas in The Netherlands. The windspeeds for the graph below are assumed to be 24 hours a day for 365 days a year. Accumulating the powercurve of the Airturb Model One system we have also calculated the inverter efficiency at 90% and the savonius type windturbine coefficiency at 30% based on a heigth of 10 meters.
