Eco Trees

Besides the "traditional" solar systems, which transform solar energy into electricity, there are solar towers, constructions that besides the electricity production allow the cereals cultivation, producing food.

The operating principle of a solar tower is quite simple: to the tower bottom there is a will, which is heated directly by the sun. The heat allows the cereals growth, the hot air goes then up, in the concrete portion of the tower, which put in motion wind mills which produce electricity.

The only problem of the solar towers represents the feasibility only for very large buildings, so this type of solar system was implemented on a large scale. However, there is in plan the construction of such structures in Namibia, a country that enjoys space and over 300 sunny days per year. For beginning, the towers will have approximately 1.5 km in height and 280 meters in diameter.
