why not just buy one of those compressed air cars and keep a panel or two on the roof ? drive to work and when you come out its charged and ready to go again !
well it would have to count towards the usual top up of compressed air but seriously it would give more power return than using the panel to make hydrogen and unlike the hydrogen that needs storing which you can't do you could store it as compressed air
