据外煤报道,德国卡尔斯鲁厄理工学院最新开发了一项无线局域网技术,打破了最快的WiFi网络速度纪录,并可令1公里以外的用户每秒钟下载40GB,即相当于10部时长各为2小时的高清电影。技术近日,日本宣称成为世界上首个成功从沿海化石燃料“可燃冰”中提取甲烷的国家。可燃冰是一种甲烷水合物,形似果冻,广泛埋藏于世界各地的大陆架之下。能源专家普遍认为,可燃冰可能是人类下一个主要的替代能源。甲烷水合物是甲烷和水的混合物,容易在海洋沉积物多或永久冻结带的地下形成,当地的化学反应和微生物将 According to reports from outside the coal, Karlsruhe Institute of Technology in Germany recently developed a wireless LAN technology, breaking the fastest WiFi network speed record, and can be 1 km away users download 40GB per second, which is equivalent to 10 Duration of 2 hours each of the high-definition movies. Recently, Japan claimed to be the first country in the world to successfully extract methane from coastal fossil fuel “combustible ice”. Combustible ice is a type of methane hydrate that looks like a jelly and is buried extensively below the continental shelf all over the world. Energy experts generally agree that combustible ice may be the next major source of human alternative energy. Methane hydrate, a mixture of methane and water, is easily formed underground in marine deposits that have many or permanently frozen strata, and local chemical reactions and microorganisms
