Rolando Ratti, fabbro di Malvaglia, ha concepito un collettore da applicare al camino. Nell'impianto viene fatta passare l'acqua per i radiatori, che viene così riscaldata. Un sistema ingegnoso e promettente che permette di sostituire la nafta con la legna per il riscaldamento delle abitazioni. Da "Il Regionale", 06.08.1979. Di Graziano Terrani. Commento di Edoardo Gatti da "La storia del Regionale", 28.02.2007.
