Cool Towers

The Russian State Committee for Television and Radio Broadcasting has agreed to demolish the Shabolovka radio tower in Moscow. It is a 50-story conical structure of steel latticework, designed by the engineer Vladimir Shukhov. It was commissioned by Lenin and completed in 1922.

Hyperboloid structures are more superior in stability towards outside forces than “straight” buildings.

But the shape gives large amounts of unusable volume. This can be used in purpose-driven structures, such as water towers (to support a large mass) and cooling towers. As the water first evaporates and rises, the narrowing effect helps accelerate its flow up into the wider upper part where the hot air mixes with the cooler air of the atmosphere.
