It's been the documentation that has been difficult. I wholly miscalculated the level of disbelief that the claim would generate. Air flow patterns are quite hard to document without specialized laboratory equipment and cooperating engineering expertise. What I was able to learn developed over time by way of painstaking observation of smoke tracers and 24 hour multi-point chart recordings of local environments. The reservoir does not get thermally polluted and neither does the current.
Passive convection is a low intensity heat transfer mechanism.
Segregating the passive flows greatly improves its efficiency. This might have diverse useful applications, including things like controlled chemical deposition as well as heating and cooling applications. Only some basic facts are known about the structural details of the turbulent convection stream. Rhythmic patterns that allow working fluid to pass through the stream without interrupting the stream can be observed and the rate of flow is nominally 8 times the rate of normal turbulent convection. Given the right dimensions and temperatures, drawing fluid from a slit along the streamward edge of a heat transfer surface at the right rate will trigger a confined sheet of organized turbulence to propagate over the whole surface.
