(EN) UNBOUNDED VORTICAL CHIMNEY
(FR) CHEMINEE TOURBILLONNAIRE NON BORNEE
Abstract
(EN)
A solar energy collection structure (110) uses the greenhouse effect to heat air between a dark-coloured base (100) and a transparent upper surface (104). Wind vanes (202) located between the base (100) and the transparent surface (104) cause the moving, heated air (118) to rotate about the center of the structure. Air escaping through a centrally located aperture (106) in the transparent surface (104) has a vortex-like flow which alleviates the need for a physical chimney structure to prevent ambient air from mixing with the escaping air. To produce commercially significant power, a collector approaching 106 m2 in size is contemplated. The sun provides approximately 1 kW/m2 and thus a collector with a radius of 1 km provides an energy input of $m(k)3 x 109 W to be converted to output power by associated turbine driven generators. Other benefits of this encapsulation of the world's weather cycle include air conditioning on a grand scale and rain making.

L'invention concerne une structure de collecte d'énergie solaire (110) utilisant l'effet de serre pour chauffer l'air entre une base de couleur foncée (100) et une surface supérieure transparente (104). Des ailettes à vent (202), situées entre la base (100) et la surface transparente (104), permettent la rotation de l'air en mouvement chauffé (118) autour du centre de la structure. L'air s'échappant à travers une ouverture centrale (106) de la surface transparente (104) présente une trajectoire tourbillonnaire, ce qui évite d'avoir à utiliser une structure de cheminée physique pour empêcher l'air ambiant de se mélanger avec l'air s'échappant. Pour produire une puissance importante d'un point de vue commercial, un collecteur de près de 106 m2 est prévu. Le soleil fournit à peu près 1 kW/m2, un collecteur présentant un rayon d'1km fournit donc une entrée énergétique de $m(k)3 x 109 W, qui est transformée en puissance de sortie, par association avec des turbo-générateurs. Cette encapsulation du cycle météorologique mondial présente un intérêt dans la climatisation à grande échelle et dans la production de pluie.
