Le fait de pr\u00e9alablement bouillir le tubercule multiplie sa puissance \u00e9lectrique par dix comparativement \u00e0 un morceau non trait\u00e9. La pomme de terre produit une \u00e9nergie qui est cinq fois moins ch\u00e8re qu\u2019une pile D de 1,5 V et six fois plus \u00e9conome qu\u2019une lampe \u00e0 k\u00e9ros\u00e8ne, souvent utilis\u00e9e dans des pays en voie de d\u00e9veloppement ou sous-d\u00e9velopp\u00e9s.<\/p>\n<\/p>\n<h4>Chercher son \u00e9nergie dans la nature<br \/><\/h4>\n<\/p>\n<p>Les scientifiques ont d\u00e9cid\u00e9 d\u2019ouvrir cette technologie aux pays les plus d\u00e9favoris\u00e9s afin qu\u2019ils puissent l\u2019adopter sans avoir \u00e0 acheter de licences.
