Theme B: Creating a livable, healthy and environmentally viable citieselectricity systems, solar hot air chimneys, [4] sunlight reflecting and dispersingsystems. [5] Harvest of wind energy can be performed through wind catcher, [6]wind cowl [7] connected to ventilation tubes, small wind turbines, [8] , windinduced pressures around buildings, [9, 10, 11] thermal induced ventilationtechniques.Plants absorbing solar energy can change carbon dioxide to give out oxygen andsmells that will contribute to human health, if suitable plants are grown. This,together with moisture given out by green leaves, will contribute to provideoptimized air quality. Also some green food plants can be grown using organicmeans, aiming at providing some food, helping to relieve the demand of farmland.Energy for transportation of food is reduced.3.
