What if we could tap into water as a source of clean energy? What if it could provide hydrogen that we could use in fuel cells or burn with no carbon dioxide messiness?
The key to unlocking water’s potential as an energy source is being able to split the water molecule, H2O, into its atomic components, hydrogen and oxygen. Plants do this all the time (and it’s a good job too because we breathe the oxygen). A new project is trying to split water molecules efficiently using just visible light – and borrowing a few tricks from the electronics industry along the way.
