| Here are the photos of this morning preliminary inspection to the soccer and athletic stadium of my small city. Hope images aren't too big.
Here we are:
This is the tower we are going to climb. about 30 meters high, made by 3 section of about ten meters of steel pipe, the diameter is about 55 cms (22-23 inches)flanged at the junctions. I assure you that despite that, at the top of the tower you will feel like you are in a boat. Oscillations are small, only fraction of a centimeter i suppose, but really scaring.
As you can see, towers are higer than any other building in the surrounding area.
The stadium is VERY near to the sea. Only a road betwen the tower we choose and the beach. Thogh this is a touristic city, this part of the beach is not suitable for that due to trees continously bringed in by the near river. Even if they periodically clear the beach surface from them. If we will get good report from anemomether, we plan to place a wind turbine about 20 KW a little (50 metres) right (south) of this photo, in a public field (we already got the permission from municipality) The place is ideal to get maximum effect from the "sea breezes", wind caused by the temp difference between sea and ground. They are here even (and expecially) during the hot summer days, when the azorres or african anticyclon stay over Italy for about 2 months. Not very windy, but anyway 4-6 hours each day.
Another shot from the same point. I was at the lowest platform
This is from the top of the tower. I didn't remember to take some panoramic photos cause I was here to take some close picture of the structure, in order to find the best way to place the anemomether respecting safety issues.
This is the anemomether we are going to install. It comes from APRS world, in USA, via a spanish importer (you can see the sticker). We choosed it due to his low energy consumption (7mA), high memory capacity (6 months with a step of 30 seconds) and flexibility (it works from 7 to 45 volts, letting us choose the batteries we want to).
Also, the memory stick is removable, and that mean we don't have to bring on the tower a laptop, we can just extract it and place another one in its place, without loosing a second of logging. Cards costs about ten dollars.
