Comment est-ce possible?Tout simplement en installant les panneaux solaires la\u0300 ou\u0300 il ne fait jamais nuit, la\u0300 ou\u0300 le soleil brille toujours a\u0300 son intensite\u0301 maximale, c\u2019est-a\u0300-dire&#8230; dans l\u2019espace.<\/p>\n<p>Il s\u2019agit du projet Ohisama, qui doit e\u0302tre lance\u0301 par l\u2019agence spatiale japonaise en 2025. Son objectif: mettre sur orbite un satellite avec d\u2019immenses panneaux solaires et renvoyer toute l\u2019e\u0301nergie re\u0301cupe\u0301re\u0301e vers la terre.<\/p>\n<p><b>Un projet ancien mais a\u0300 l\u2019e\u0301poque trop cou\u0302teux<\/b><\/p>\n<p>Les scientifiques ont trouve\u0301 le moyen de renvoyer l\u2019e\u0301lectricite\u0301 vers la terre en la convertissant en ondes radio. Ces ondes sont ensuite transmises vers une station au sol qui va les reconvertir en e\u0301lectricite\u0301. En posant la question, a priori, il n\u2019y aurait aucun danger ni pour les avions, ni pour les oiseaux.<\/p>\n<p>Ce n\u2019est pas un concept nouveau. Pour la petite histoire, ce sont les Ame\u0301ricains qui ont commence\u0301 a\u0300 s\u2019y inte\u0301resser lors du premier choc pe\u0301trolier en 1973. Mais ils ont rapidement abandonne\u0301 pour des raisons de cou\u0302t. Aujourd\u2019hui, avec les lanceurs re\u0301utilisables et surtout, l\u2019urgence e\u0301nerge\u0301tique, ce sont de\u0301sormais tous les grands pays qui recommencent a\u0300 s\u2019y inte\u0301resser. Me\u0302me la France, avec l\u2019Agence spatiale europe\u0301enne et le projet Solaris. Mais on n\u2019en est encore qu\u2019a\u0300 des expe\u0301rimentations terrestres.<\/p>\n<p><b>Une premie\u0300re centrale comple\u0300te pre\u0301vue par la Chine en 2030<\/b><\/p>\n<p>Le Japon est plus avance\u0301 avec ce premier satellite test qui sera lance\u0301 l\u2019anne\u0301e prochaine, en 2025. Mais c\u2019est la Chine qui pourrait coiffer tout le monde au poteau. Elle pre\u0301voit d\u2019avoir une ve\u0301ritable mini-centrale ope\u0301rationnelle de\u0300s 2030. Avec l\u2019objectif d\u2019atteindre la puissance d\u2019une centrale nucle\u0301aire en 2050.<\/p>\n<p>Ce ne sera pas une mince affaire. On parle quand me\u0302me d\u2019un kilome\u0300tre carre\u0301 de panneaux solaires. Une structure immense qu\u2019il faudra construire dans l\u2019espace. Mais pour obtenir le rendement similaire avec des panneaux au sol, il faudrait couvrir une surface de plus de 20 km2. C\u2019est tout l\u2019inte\u0301re\u0302t de mettre les panneaux solaires dans l\u2019espace. Non seulement ils produiront 24h\/24h, mais en plus, ils n\u2019occuperont plus aucun espace au sol.<\/p>\n<p><strong>Pour plus d&rsquo;informations et d&rsquo;analyses sur la <span style=\"color: #ff6600\">Senegal<\/span>, suivez <span style=\"color: #ff6600\">Africa-Press<\/span><\/strong><\/p>\n","protected":false},"excerpt":{"rendered":"<p>Africa-Press &#8211; Senegal.
