Letters from the March 13, 2004, issue of Science News
Dry hole? “Tapping sun’s light and heat to make hydrogen” (SN: 1/17/04, p. 46: Tapping sun’s light and heat to make hydrogen) seems to be delivering good news for the environment: “Clean” hydrogen can be produced from water using solar energy. This seems to me, however, to be even more horrifying than the burning of […]

I believe a reader rushed to judgment regarding the environmental impact of splitting water to produce hydrogen for fuel (“Letters: Dry Hole?” above). The split water isn’t ultimately consumed, only recycled. Burning hydrogen reunites it with oxygen, returning water to the environment. Much more intriguing questions might concern the human-accelerated migration of water from liquid […]
