Exhaust hood system with fluid wall air filter

An exhaust hood system comprising:

• an intake located within a building;
• an output located outside of the building;
• a duct connected between the intake and the output, the duct fluidly connecting the intake and the output together, the duct having
• a vertical intake portion positioned within the building;
• a vertical exhaust portion positioned outside of the building;
• and
• a horizontal portion positioned between the vertical intake portion and the vertical exhaust portion;
• a filter positioned within the duct between the intake and the output, the filter emitting a liquid within a portion of the duct;
• a drain in fluid communication with the filter;
• a drain line in fluid communication with the drain;
• a valve in fluid communication with the drain line;
• a recirculation line in fluid communication with the valve, the recirculation line in fluid communication with the filter;
• a pump in fluid communication with the valve and the recirculation line, the pump directing fluid from the valve, through the recirculation line, and to the filter to emit the liquid;
• an energy harvesting system including
• a power source;
• an electric turbine in electrical communication with the power source;
• and
• a thermoelectric generator in electrical communication with the power source;
• and
• a chamber in fluid communication with the drain, the chamber comprising a photosynthetic agent or a fungal agent,
• wherein a flow path is defined from the intake and to the output,
• wherein a portion of the vertical exhaust portion of the duct is coupled to the chamber, and
• wherein the cross-section of the portion of the vertical exhaust portion of the duct that is coupled to the chamber increases along the flow path, and
• wherein the cross-section of the chamber is larger than a cross-section of the vertical intake portion of the duct.
