INTRODUCTIONThe floating solar chimney technology is the source of renewable energy for the present and future world.

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

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

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

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

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

PARTS UNDER OPERATION AND THE PRINCIPLETHE GREENHOUSETHE FLOATING SOLAR CHIMNEYTHE TURBO GENERATOR

SOLAR AERO ELECTRIC POWER PLANTSAEP is similar to Hydro Electric Power Plant as water turbines convert dynamic energy (due to gravity) to rotational energy similarly in SAEP the dynamic energy (due to buoyancy) is converted to rotational energy.

In both of these power plants power output is proportional to height.

WHY FLOATING CHIMNEY?In order to build efficient and cheap SAEP and less expensive than concrete solar towersFloating solar chimneys are lighter than air structures that can be up to 3 km providing efficient air up draft.

SOCIAL AND ECONOMIC BENEFITSReduce production of 900,000 tons of greenhouse gases annually.Agriculture is promotedCondensation at night provides moisture to soil

TECHNICAL ISSUESFloating SAEP must be free from heavy winds.

Large land area required not suitable for area with high cost / acre

Corrosion of materials

IS IT FEASIBLE?Easily available parts in commercial market and can be installed anywhere

Green technology that overcomes the present energy crisis and global warming

Renewable energy source and efficient electricity production

CONCLUSIONThis technology has the potential to replace all the energy activities related to fossil fuelled activities and to eliminate energy crisis

We should start building floating solar chimneys to bring a solution to global warming and in succeeding to generate zero emission clean electricity
