Turning Sand into fuel - Silicon oil as an energy carrier

High grade energy is needed to transform silicon oxide into pure silicon, to be hydrated producing the silanes. One possibile way to go about this is to use photovoltaic electricity to disassociate hydrogen and oxygen from water. Those gases could then be used to process sand into pure silicon and to obtain silanes.
