He doesn't tell us how this will work--but presumably he and other astrobiologists
like to use electricity when the Sun isn't shining and the wind isn't blowing.

have until now thought water was a potential oxygen source only on planets such as Venus, where a runaway greenhouse effect drove temperatures to spiral higher and higher, eventually boiling away the oceans.
