美国能源部爱达荷国家实验室的科学家研制出一种手提箱大小的核电站,能够在火星、月球或者任何外太空基地发电,发电量为40千瓦,能供八个普通家庭使用。这种小型的发电设施正是外太空发电的理想设备。因为其小巧,可以将其安置在无人星球的陨坑或者洞穴中;而其轻便性也是在外太空正常工作的一个基础要件。美国宇航局已考虑将这种微型核电站用于氧气或氢气发生器的电力支持,另外也可用于有人或无人电子侦察设备的电力供应。研究人员计划为该设备建立一个物理演示室,并在明年对其性能进行测试。
Humans might not be living on Mars or the moon anytime soon, but scientists might have just overcome one major hurdle on the route to interstellar habitation: electricity.
Scientists at the U.S. Department of Energy's Idaho National Laboratory have designed a suitcase-sized nuclear plant that can power up to eight normal-sized homes. Thanks to its size and durability, the plant can provide fission power not only on Earth, but on the moon, on Mars, or any other place NASA requires a power generator.
While most nuclear plants generate hundreds or thousands of megawatts of electricity, this portable generator would create only 40 kilowatts. This smaller size is ideal for the type of conditions seen in space, said James Werner, lead researcher on the project.
