"Modern science has been a voyage into the unknown, with a lesson in humility waiting at every stop. Many passengers would rather have stayed home." - Carl Sagan Thu, 22 Oct 2009 12:19:13 +0000 http://wordpress.com/ hourly 1 http://enochthered.wordpress.com/2008/04/25/anti-nuclear-quote-of-the-day-8/#comment-380 Klaus A Fri, 25 Apr 2008 18:04:05 +0000 http://enochthered.wordpress.com/?p=103#comment-380 Actually, it is not COMPLETELY wrong. The poster just does not know what he is talking about. High temperature electrolysis is endothermic. At high temperatures the electrical energy required to break the H-O bonds is less than the resulting H2 energy content (lower heating value). So yes, from a purely electrical energy standpoint, there's more energy in the H2 than supplied electrically to the electrolyzer. But that is just as stupid as claiming that nuclear driven Sulfur-Iodine cycle H2 production would be infinitely efficient because no electrical input is required. Only thermal.
