L’id\u00e9e, bien que farfelue, se r\u00e9v\u00e8le assez int\u00e9ressante d\u00e8s lors qu’on observe que l’hydrog\u00e8ne contenu dans l’urine est beaucoup moins li\u00e9 que dans l’eau. Une production d’hydrog\u00e8ne par hydrolyse de l’eau demande une diff\u00e9rence de potentiel entre les \u00e9lectrodes de 1.23 V contre 0.37 V pour l’urine.<\/p>\n
Il faut n\u00e9anmoins relativiser car la fili\u00e8re de production d’hydrog\u00e8ne par \u00e9lectrolyse n’est pas la plus efficace. En effet, elle co\u00fbte \u00e9nerg\u00e9tiquement plus cher que la fili\u00e8re thermochimique mais a l’avantage de ne produire aucun autre d\u00e9chet que ceux n\u00e9cessaires \u00e0 la production d’\u00e9lectricit\u00e9.<\/p>\n
<\/p>\n
Il faut donc peser le pour et le contre avant de se r\u00e9jouir. Bien s\u00fbr, si l’\u00e9lectrolyse est r\u00e9alis\u00e9e \u00e0 partir d’\u00e9lectricit\u00e9 renouvelable, par exemple \u00e0 base d’\u00e9nergie solaire, il n’y a tout simplement aucun d\u00e9chet produit, on a m\u00eame un bilan des d\u00e9chets n\u00e9gatifs vu qu’on se d\u00e9barasse de l’ur\u00e9e contenue dans l’urine.<\/p>\n
