Solar Cell Factory III: Earth Tube
Factory for making solar cells.
The big tube in the middle is the fresh air intake to the factory. In summer when the air is too hot it is cooled in the earth tubes on its way to the factory. In winter when the air is colder than the ground it is pre-heated in the earth tubes.
To the right and on the roof you can see the backsides of the solar cells that produce electricity for the factory´s own requirement.
