The discussion revolves around the optimization of a hyperboloid tower's dimensions to maximize the venturi effect generated by thermal updraft from human body heat, particularly after physical activity on a hot day. The focus includes theoretical considerations of design parameters such as base size, skirt dimensions, and height.
Participants express differing views on the significance of human body heat in contributing to the venturi effect, indicating that there is no consensus on the extent of its impact.
Assumptions regarding the effectiveness of human body heat as a power source and the specific design parameters of the hyperboloid tower remain unresolved.
For a natural updraft tower, the larger the better. However, the human body won't contribute significantly to it.Kai G said:What are the ideal dimensions of a hyperboloid tower that would maximize the venturi effect started by thermal updraft from human body heat (assuming previous physical activity on a hot day)? Given a 40ft base, how large should the skirt be and how high off the ground? A vertically symmetrical hyperboloid may not be required.

Probably, yes. People aren't a very dense power source, but 20 people is about 1400 W of sensible heat, which should be enough to induce a measurable convection.Kai G said:The intent is to act as a gathering place. Would 20+ bodies be sufficient?
