Micro-scale heat and electricity generation by a hybrid solar collector-chimney, thermoelectric, and wind turbine

Energetic Valorization of the Innovative Building Envelope: An Overview of Electric Production System Optimization

“…The thermoelectric generators heat the fresh air, causing it to ascend due to buoyancy force and the chimney effect, passing through the vertical chimney and slanted collector. Upon reaching the turbine blades, the rising air induces rotation, generating electricity generation [25]. This system encompasses a solar air collector, solar chimney, thermoelectric generators, and a Savonius wind turbine.…”

Indeed, the adaptability of solar paint to various surfaces, the aesthetic integration into building envelopes, ease of application using a simple brush, low-cost, adjustable electrochemical performance, and environmental friendliness with no emission of ozone-depleting substances are all advantages of this exceptional paint.…”
