Imma try my hand at making a DIY mini solar chimney: black spray paint, duct tape, 1.5 meter flat ducting, and a preexisting duct hole (for ventilation when we installed the stove) in the hottest room in the house. Coupled with metal foil taped to the windows, hoping to crash the daytime temperature in that room tomorrow as the heat here in #Ireland hits a predicted 30°C (national disaster territory, FYI).
