Some feel that open field testing is the only true way to test the performance of a micro
wind turbine, stating that other testing leaves room for the data to be unrealistic if it is
only tested under optimal conditions. However to accurately test the results more testing
methods will be needed in order to compare results from different tests.
The next testing method that will be looked at will be the rpm gauge to see what kind of
energy is generated by subjecting the turbine to various degrees of rpm speeds and
measuring what kind of results are delivered. In order to accurately measure how many
rpms are being subjected to the turbine a drill or rated motor will need to be utilized so
that the turbine can be accelerated up to a pre-determined rpm rotational speed and
kept at that rotational speed long enough to obtain an accurate measurement of the
energy produced. This will need to be reproduced multiple times at different rotational
speeds and the results compared to one another as well as the rated values. The
following image shows how such a test can be implemented using a drill and an
automobile transmission as an example.

Since this test will be the most accurate way of determining what kind of energy will be
produced at a certain rpm speed the collected data could be used to compare the
actual performance of the turbine with the rated values of the turbine supplied by the
manufacturer.
The last and final testing method that will be researched will be the automobile
approach. As previously stated this will entail mounting the turbine atop of a moving
automobile and using the speed of the car at various speeds to simulate wind speed
moving across the blades of the wind turbine. In order for this kind of testing to work a
place of relatively dead air space will be needed so that the wind speeds from outside
breezes will not interfere with the testing data. Most likely the most ideal situation will be
to utilize parking garages when they are not in use so as the testing does not interfere
with normal traffic activity.
