太陽熱空気集熱器を用いて、空気を加温する。加温した空気を煙突状柱体に集中させ上昇気流を生じさせる。この煙突の中の上昇気流中に風車羽根車を設置する。風車を回転させて、動力を取り出し、小型モータを転用した発電機を駆動し発電を行う。本研究では、第一段階として、上昇気流の発生と風車から動力を取り出すこと、および微弱ではあるが、発電機から電力を取り出すことをめざし、成功させた。

The urban canopy model could reproduce typical temporal change of heat fluxes in sunny days over urban canopy with and without vegetation. During consecutive sunny days, daytime sensible heat flux did not show rapid increase from day to day over the modeled urban canopy with vegetation. Analysis of the model simulation clearly indicated this was due to the vegetation's ability to subtract water in deep soil layer and to use it for evapo-transpiration. Another interesting feature found in the simulation with the vegetation case was that vegetation canopy forms cool island through development of relatively cool mixed layer with large turbulence, associated with drag and strong wind shear by vegetation, and small sensible heat flux from the canopy to upper layer.The urban canopy model could reproduce typical temporal change of heat fluxes in sunny days over urban canopy with and without vegetation.
