My wife and myself are enthusiastic Geocachers. Geocache is a world wide game for which a subject is hidden in the field. The subject can be found if you know the coordinates and if you have a GPS. In every Geocache there is a small book in which you can put your name if you have found it. At home, you log the Geocache on your computer if you have found it. One of the Geocache types is the Mystery for which you have to solve a puzzle about a certain subject to find the cache coordinates. Last year I have made the two Mysteries: "Wind Turbine Theory" and "Wind turbine practice". The description of the Mystery is in Dutch and in English. The cashes are hidden in the small village Boskant, about 15 km north of Eindhoven in the Netherlands. My caches are only accessible for premium members of Geocache.
For Wind Turbine Theory, ten questions have to be answered about my free public report KD 35 which is available in English and in Dutch on my website
www.kdwindturbines.nl. Every correct answer gives a number of the coordinates. The cache description contains a checker with which you can check if all answers are correct. At this moment 92 people have logged this Geocache which means that KD 35 can be understood by people who are not specially interested in wind energy but more in Geocache.
For Wind turbine practice, ten questions have to be answered about the folder of the seven free VIRYA-designs and about the technical drawings of every wind turbine which are incorporated in the free manuals or KD-reports. The folder is available in English and in Dutch but the manuals and the drawings are only in English. At this moment 70 people have logged this geocache but Wind turbine practice was placed some months later than Wind Turbine Theory.
By making these two geocaches, probably more people have studied wind energy in one year than wind energy enthusiasts did this in the three years since this information is available on my website. The two puzzles can be solved by any premium member of Geocache all over the world and if you did so, your knowledge of wind turbines will have increased a lot. But to log the geocache, you have to visit my village Boskant in the Netherlands. If you do so, you are invited to visit my home and drink a cup of coffee.
