If the tower has a broad base with space for air to enter and the tower or building is tapered to narrowing at the top and the top of the tower is colored black with a lighter colored base, would wind speeds be sufficiently increased by solar heating to drive one or more propelers and turbines throughout the height(calculate best height)? This design, if feasable could be located any place there is sun and would not endanger birds or necessarily look obnoxious. Do nuclear towers look obnoxious? It might not even need too much sun to cause a strong updraft. Deserts could be packed with these and if direct electricity plus hydrogen and oxygen were produced by electrolysis on a more or less continuous basis, a new industry of production, storage and transportation of byproducts could be created. It sounds great … if enough wind speed is generated.
Or if design is broad lower building; similar concept but with many smaller turbines strategically located as calculated by engineers…?
