Ricercatori del Politecnico di Zurigo hanno sviluppato una tecnologia capace di generare combustibili liquidi sfruttando luce del sole e aria, ciò che permette di ricavare un prodotto neutro per quanto concerne le emissioni di anidride carbonica.
La catena del processo termochimico che porta al rivoluzionario risultato è stata mostrata giovedì in condizioni reali.
Cuore della sperimentazione è una miniraffineria, installata su un tetto, in grado di "sfornare" un decilitro al giorno, pur nelle condizioni climatiche locali non ideali. Il sistema permette d'ottenere una miscela d'idrogeno e monossido di carbonio, trasformabile poi in cherosene, metanolo o altri idrocarburi.
La squadra guidata da Aldo Steinfeld sta ora lavorando a un reattore solare di grandi dimensioni, realizzato nelle vicinanze di Madrid, nell'ambito del progetto dell'Unione Europea "SUN-to-LIQUID".
