“Green” Village: Third project in Bielefeld, Germany

This was the third and the greatest project in Bielefeld. Here is our construction: The Split Rock Photovoltaic Lighthouse.

There were some other great ideas too, as you can see in this photo gallery below:

Second Project: Renewable Energy Sources Paintings in Bielefeld, Germany

Comenius Projects 2012-2014.

This was the second out of the three projects in Bielefeld, Germany. The students under the instructions of the German team designed those beautiful paintings regarding Renewable Sources Energies (RES).

The Greek Team in action…Final results. We must admit that all the other paintings from German, Poland, Turkey, Denmark and Italy were also gorgeous!!! Thanks to all students and teachers contributing to this great project!!!

Yamie Poster: First project in Bielefeld, Germany

Comenius 2012-2014

This was one of the three construction projects during our visit in Bielefeld, Germany. The poster was made by smashed tiles on a big wooden board. Thanks to all students from Germany, Greece, Denmark, Poland, Italy and Turkey for their excellent work!!!

Thanks goes especially to the German team who organized and instructed the whole project!

“Green Model” : Photovoltaic Lighthouse

Split Rock Lighthouse is a lighthouse located southwest of Silver Bay, Minnesota, USA on the North Shore of Lake Superior. The structure was designed by lighthouse engineer Ralph Russell Tinkham and was completed in 1910 by the United States Lighthouse Service at a cost of $75,000, including the buildings and the land. It was built in response to the loss of ships during the famous Mataafa Storm of 1905, in which 29 ships were lost on Lake Superior.[3] One of these shipwrecks, the Madeira, is located just north of the lighthouse. The light was first lit on July 31, 1910.

Our project: We will build the model of this historical lighthouse in a scale of 1:300 and will light it up for the first time using Photovoltaic energy!!!

The model will be placed eventually on the “Green Village” among other models at Bielefeld, Germany as the final goal of our project.

 

Energy Production: Visit to the Photovoltaic Park, Livadi Ropa – Corfu (Photos)

Short Report: Our visit to the Photovoltaic Park, Livadi Ropa – Corfu

On November 16th the Comenius-Team of our school visited the Photovoltaic Park in Livadi Ropa (west Corfu), one of the three photovoltaic parks on our island. It was a beautiful sunny day; the perfect weather conditions for our excursion!

The supervisor of the park was kind enough to show us around and answer to all of our questions.

Some interesting facts…

Photovoltaic systems convert solar light into electricity. A photovoltaic system is made up of one or more panels, each of which consists of solar cells, an inverter, electrical interconnections and other equipment. There are two kinds of photovoltaic systems; the fixed and the tracking solar panels. The fixed are always aimed directly at the east.

The trackers on the other hand can move and collect more sunlight, but they need more space and cannot be used in windy areas. The photovoltaic park in Livadi Ropa has only fixed panels.

The expert also told us that the photovoltaic park was built in just 2 ½ months and that unfortunately a number of trees had to be cut down for its construction. An expansion has already been planned and while we were there, new solar panels were actually being delivered by a transport company.

The produced electricity is being sold to the Public Power Corporation (national electricity company). The rate is at the moment 0,25 € per kilowatt.
