The opening on the sides allows for ventilation and a peek at the flames, and the CRA-Carlo Ratti Associati team says that the arrangement relies on the Venturi effect, drawing in more air to keep the combustion going. The team adds that the system can operate for up to negative 20 degrees Celsius and other extreme conditions.
