L\u2019\u00e9nergie et la chaleur ainsi produites permettent de purifier de l\u2019eau impropre \u00e0 la consommation (sal\u00e9e ou pollu\u00e9e) au cours d\u2019un processus de distillation (jusqu\u2019\u00e0 5000 litres d\u2019eau potable par jour) sans aucun filtre \u00e0 changer.

En effet, rappelons que pr\u00e8s de 783 millions de personnes n\u2019ont pas d\u2019acc\u00e8s \u00e0 l\u2019eau potable (ce qui est autant probl\u00e9matique pour les cultures que pour le pr\u00e9vention des maladies), 1,2 milliard sont priv\u00e9es d\u2019\u00e9lectricit\u00e9 et 4,2 milliards ne peuvent pas se connecter \u00e0 internet. Selon le chef de projet, \u00ab la seule condition pour que cela fonctionne, de l\u2019eau sale et beaucoup de soleil \u00bb. Watly est donc un nouveau type de g\u00e9n\u00e9rateur multi-fonctionnel, qui plus est, construit \u00e0 pr\u00e8s de 90% avec des mat\u00e9riaux recyclables. Son empreinte carbone est donc faible et sa dur\u00e9e de vie de l\u2019ordre de 15 \u00e0 20 ans selon les estimations. La particularit\u00e9 de ce g\u00e9n\u00e9rateur est de combiner solaire photovolta\u00efque et solaire thermique, comme l\u2019explique M. Attisani : \u00ab L\u2019eau est utilis\u00e9e pour refroidir les panneaux solaires photovolta\u00efques afin qu\u2019ils puissent fonctionner \u00e0 une efficacit\u00e9 optimale. Le r\u00e9chauffement de l\u2019eau permet ensuite d\u2019optimiser le syst\u00e8me solaire thermique\u00ab . On notera que la structure mesure 40 m\u00e8tres de long et qu\u2019elle p\u00e8se pr\u00e8s de 15 tonnes !<\/p>\n<p><strong>Sources<\/strong>&nbsp;:&nbsp;<a href=\"https:\/\/watly.co\/watly\/\">Watly.co<\/a>&nbsp;\/&nbsp;<a href=\"https:\/\/www.maxisciences.com\/energie-solaire\/watly-l-039-invention-qui-pourrait-fournir-de-l-039-eau-et-de-l-039-electricite-a-des-millions-d-039-africains_art37718.html\/\">maxsciences.com<\/a>&nbsp;\/&nbsp;<a href=\"https:\/\/www.pv-magazine.com\/news\/details\/beitrag\/watly-launches-crowdfunding-campaign-for-its-off-grid-power-generator-and-water-purifier_100024058\/#axzz49dxpDofE\">pv-magazine.com<\/a>&nbsp;\/&nbsp;<a href=\"https:\/\/edition.cnn.com\/2016\/05\/09\/africa\/watly-solar-hub-ghana\/\">cnn.com<\/a><\/p>\n<p class=\"bawpvc-ajax-counter\" data-id=\"16130\">(851)<\/p>\n<!--CusAds0-->\n<div style=\"font-size: 0px; height: 0px; line-height: 0px; margin: 0; padding: 0; clear: both;\"><\/div>","protected":false},"excerpt":{"rendered":"<p>Une start-up italienne veut r\u00e9volutionner la vie de millions de personnes en rendant accessibles \u00e0 la fois eau, \u00e9lectricit\u00e9 et&#8230;<\/p>\n","protected":false},"author":1,"featured_media":16131,"comment_status":"open","ping_status":"open","sticky":false,"template":"","format":"standard","meta":{"_exactmetrics_skip_tracking":false,"ngg_post_thumbnail":0,"_jetpack_newsletter_access":"","_jetpack_dont_email_post_to_subs":false,"_jetpack_newsletter_tier_id":0,"_jetpack_memberships_contains_paywalled_content":false,"_jetpack_feature_clip_id":0,"_jetpack_memberships_contains_paid_content":false,"footnotes":"","jetpack_post_was_ever_published":false},"categories":[26],"tags":[196,101,100,684,5999],"class_list":["post-16130","post","type-post","status-publish","format-standard","has-post-thumbnail","hentry","category-solutions","tag-afrique","tag-energie","tag-solution","tag-video","tag-watly","wpcat-26-id"],"jetpack_shortlink":"https:\/\/wp.me\/p631RN-4ca","jetpack-related-posts":[{"id":12984,"url":"https:\/\/www.laterredufutur.com\/accueil\/watly-linvention-qui-pourrait-fournir-de-leau-et-de-lelectricite-a-des-millions-dafricains\/","url_meta":{"origin":16130,"position":0},"title":"Watly, l&rsquo;invention qui pourrait fournir de l&rsquo;eau et de l&rsquo;\u00e9lectricit\u00e9 \u00e0 des millions d&rsquo;Africains","author":"Admin","date":"30 juillet 2016","format":false,"excerpt":"Pour am\u00e9liorer les conditions de vie de plusieurs millions de personnes, une start-up italienne a con\u00e7u un dispositif innovant capable d\u2019utiliser l\u2019\u00e9nergie solaire pour fournir de l'eau potable, de l'\u00e9lectricit\u00e9, et m\u00eame un acc\u00e8s \u00e0 Internet.
