This paper provides a review of research and development of the SCPP technology. Besides, a feasibility of implementing the SCPP technology is analyzed, and it is found that this green technology can be considered as an alternative renewable energy source for Thailand. Furthermore, a computational fluid dynamics (CFD) based program for steady-state viscous incompressible thermal flows is introduced and utilized to study air flow in the SCPP. The numerical results reveal that the curved junction with a diffuser is the most suitable model for adopting the SCPP technology in practice. Keywords : electricity generation, solar chimney
