Isn the power delivery of 120MW in a paper by Prof. Kröger contradicting the values here presented?
No, since the very low maximum power output of 115MW in the paper Performance Evaluation of a Solar Chimney Power Plant at the 2001 ISES congress in Australia represents the worst case according to the understanding with our company (compare Q.9), whilst the best case is beyond the envisaged 400MW power delivery mark. This surprisingly great difference is caused by the small weight difference (buoyancy) between the much heavier inside and outside air column. Small errors in the latter will multiply with the calculation of the difference and inflate the error in buoyancy. The minimization of this difference in power generation to less than10% for insurance purposes is one of the main tasks of the feasibility study. In addition none of today’s design improvements were included like the use of solar glass, anti-reflection layers at top and bottom of the glass, IR reflection layer at the glass bottom in the whole collector improving power output over the whole collector area, streamlined s
