Is the leap from a small pilot to a 200/400MW plant not too risky?
No, since the chimney structure will be completely insured against design and building failures. Construction will be double-checked. Power production is also completely insured, based on the guaranteed expert opinion of Prof. Kröger, University Stellenbosch. To that end the collector area increase required to compensate the shortfall in power production will be insured. This will at the same time increase the greenhouse area by 150% of the collector area added. Hence the insurers carry no risk, since the additional greenhouse income will quickly pay for the additional collector area. This will lead to nearly negligible insurance rates. Aeroplane manufacturers normally use a linear scale of 1 : 10 for wind channel models, the Solar Chimney uses the linear flow dynamic scale of 1 : 7,5 (200m : 1500m chimney height). Prof. Kröger’s calculations, supported by large collector model testing, will easily meet the accuracy required by the insurance company.
