Le patron d\u2019Amazon soutient un projet de fusion d\u2019hydrog\u00e8ne particuli\u00e8rement disruptif.<\/div>\n<div>Le nucl\u00e9aire nouvelle tocade des milliardaires? Depuis pr\u00e8s de quinze ans, Bill Gates finance TerraPower, une entreprise am\u00e9ricaine qui vise \u00e0 produire des r\u00e9acteurs de taille r\u00e9duite de 200 \u00e0 300 m\u00e9gawatts, six \u00e0 huit fois moins puissant qu&rsquo;un EPR. Cette fois, c\u2019est Jeff\u00a0 Bezos qui se lance. Mais pas sur le m\u00eame cr\u00e9neau que le fondateur de Microsoft. Le patron d\u2019Amazon ne vise pas le march\u00e9 des r\u00e9acteurs SMR (small modular reactors) mais celui de la fusion de l\u2019hydrog\u00e8ne. Encore exp\u00e9rimentale, cette technologie vise \u00e0 produire de l\u2019\u00e9lectricit\u00e9 en liant les atomes entre eux et non en les cassant comme c\u2019est le cas pour la fission nucl\u00e9aire.<\/div>\n<div>Si elle se r\u00e9alise, la fusion pourrait \u00e0 terme devenir le cauchemar des \u00e9cologistes car contrairement \u00e0 la fission, elle ne produirait pas de d\u00e9chets hautement radioactifs. On y est encore tr\u00e8s loin, mais Jeff Bezos, en ind\u00e9crottable optimiste, y croit dur comme fer. L\u2019homme le plus riche de la plan\u00e8te soutient la start-up canadienne General Fusion. Et hier, cette entreprise a annonc\u00e9 qu\u2019elle construirait une centrale de d\u00e9monstration \u00e0 Culham \u00e0 l\u2019ouest de Londres, l\u00e0 o\u00f9 se trouve le programme de recherche britannique sur la fusion nucl\u00e9aire. La construction d\u00e9buterait l\u2019an prochain et entrerait en phase op\u00e9rationnelle en 2025.<\/div>\n<div style=\"text-align: right\">(Challenge)<\/div>\n","protected":false},"excerpt":{"rendered":"<p>Apr\u00e8s Bill Gates, c\u2019est au tour Jeff Bezos de se lancer dans le nucl\u00e9aire.
