INTRODUCTIONINTRODUCTION The floating solar chimney technology is the source The floating solar chimney technology is the source

of renewable energy for the present and future world.of renewable energy for the present and future world.

It is a simple technology that makes use of solar It is a simple technology that makes use of solar updraft tower in which the air turbines are rotated by updraft tower in which the air turbines are rotated by the dynamic energy(buoyancy) of the up drafting the dynamic energy(buoyancy) of the up drafting warm air in the floating chimney combined with warm air in the floating chimney combined with greenhouse.greenhouse.

This green technology is cost efficient, low This green technology is cost efficient, low maintenance, highly safe, agriculturally productive, maintenance, highly safe, agriculturally productive, with high efficiency of power productionwith high efficiency of power production

OVERVIEWOVERVIEW

German engineer Prof. Dr. Ing. Jorg Schlaigh, built a German engineer Prof. Dr. Ing. Jorg Schlaigh, built a working model of a solar chimney power plant in working model of a solar chimney power plant in 1982 in Spain.1982 in Spain.

Annually 100MW power can be produced and it can Annually 100MW power can be produced and it can operate throughout the year , 24 hours a day.operate throughout the year , 24 hours a day.

In comparison with concrete solar chimneys these In comparison with concrete solar chimneys these floating chimneys are with high efficiency and low floating chimneys are with high efficiency and low cost.cost.
