见所未见（111）- 生物燃料真的能替代航空煤油开飞机吗？

昨天在美国休斯敦布什国际机场，美国的大陆航空公司首次演示用生物燃料代替航空煤油进行民用客机的飞行。以下为这次演示的照片以及最近一段时间内世界各国同类项目的新闻照片。

新能源企业Sapphire Energy公司已经利用藻类制成一种符合燃料质量标准的汽油，与当前的汽油生产基础设施相配套，这种汽油的辛烷值达到了91。日后为这些飞机提供动力的燃料，极有可能由藻类制造。75加仑容器里的藻类粘性物，在一个星期的过程中，其颜色从灰绿色变到近乎黑色。这种藻类生物反应器，是近乎xx的生产未来燃料的温床。藻类是具有3万种来源的简单有机物，许多种类可以进行转基因改良。航天和航空公司都相信，藻类制造的燃料可以作为喷气式飞机的环保燃料。藻类制造的燃料也可以混入汽油或柴油，未来某{yt}，甚至可能取代以石油为基础的汽油和柴油。
