[1] and recently reviewed by Guo et al. [2] offers \n the possibility of large scale generation of electricity using natural convection. The reasons holding \n back development concern its height (up to 1000m) and efficiency (about 2%). \n The proposal outlined in this paper is based on the solar chimney but has three additional features: \n (1) The air flow created by warm air in the chimney is required to pass through a convergent- \n divergent nozzle or venturi to multiply flow velocity. The turbine is then placed in the throat of \n the nozzle to harness the much higher flow kinetic energy. \n (2) A rectangular configuration is suggested for the chimney and a long, narrow solar collector. This \n would be easier to build and could allow multiple units to be built in parallel. \n (3) The author wondered what would happen if air flow created by the chimney was required to \n flow through several turbines in series. Would the extra turbines yield greater efficiency?","bbox":{"left":0.100143,"top":0.33779,"width":0.800445,"height":0.2348780000000001}},{"text":"Linear Configuration with one turbine \n Consider Figure 1","bbox":{"left":0.100143,"top":0.610361,"width":0.33245,"height":0.04716100000000001}}],"images_bbox":[{"left":0.238075,"top":0.668295,"width":0.470776,"height":0.28685}],"images_bbox_not_text_overlap":[{"left":0.238075,"top":0.668295,"width":0.470776,"height":0.28685}]}
