Battery electrolysis of h2O into o2 and h2 that these engage in need a consistent power source. Either the power source is the core of the earth spinning, or there is some electrical something making these nodules consistently split.<p>I'll be curious about it, but I think that climate change may slow more from lower cost land surface batteries than these electrolysis water splitting batteries and associated ecosystems. Aka I won't hold my breath... ba dum tsss
