最新实验证明从太空传输太阳能可行[凯普生物仪器网论坛] u8e.com

北京时间9月16日消息，据美国宇航局太空网9月15日报道，一位曾供职美宇航局的科学家利用无线电波，将太阳能在两个夏威夷岛屿之间传输了92英里(约合148公里)的距离。他宣称，实验成果证明这一技术可以将太阳能从卫星传回地球。

　　约翰·曼金斯(John C. Mankins)向《探索频道》演示了这项太阳能传输技术。《探索频道》为这次历时4个月的实验提供了经费，并于美国东部时间9月12日晚9点播出了实验结果。曼金斯的构想是将重达1102磅(约合500公斤)的轨道卫星收集的太阳能传输至地面一个大型接收站。

　　曼金斯曾在美宇航局工作25年之久，长期负责宇航局太空太阳能项目，直至该项目被取消。今年5月，他成功将20瓦的太阳能在两个岛屿之间传输。据曼金斯介绍，由于岛上的接收站过于小，只有千分之一的能量被接收到。这次实验耗资约100万美元，曼金斯表示，他要是有更多的资金，那么就能造出更大的太阳能阵列。

　　按照设计，在实验所用的9个太阳能电池板中，每一个的传输能力达到20瓦左右，不过为了让美国联邦航空管理局批准这次实验，每个太阳能电池板传输的能量只能限制在2瓦。尽管接收站接收的能量极为有限，但曼金斯说，地面实验证明通过大气层传输太阳能是可行的。他说：“实验并没有获得完全的成功。但我认为，此次实验表明快速、经济有效地传输太阳能是可能的。”
