Vaticano instala coletor solar

Vatican City Installs Solar Collectors To Heat, Cool Buildings VATICAN CITY—Last week, Vatican City installed solar collectors to help heat and cool its buildings. The installation includes 110 solar collectors, covering nearly 3,800 ft2 (350 m2 ), and will use absorption cooling during warm weather. The installation comes about a year after the city-state converted the roof of its Paul VI audience hall into a solar-power generator to produce energy for the Vatican’s power grid.
