Ricardo Azevedo rides his Honda NX 200 motorbike, which he converted to be powered by water, in Salto, northwest of Sao Paulo, Brazil, August 6, 2015. The Sao Paulo civil servant built the motorbike which can cover up to 500 kilometres (311 miles) fueled by just one liter of water. Dubbed "Moto Power H2O", the bike is powered by a process of electrolysis by which the water molecule is broken down into its constituent elements. Picture taken August 6, 2015. REUTERS/Nacho Doce
