In order to try out whether this even has a chance of working, we will need to send commands to the NXT over USB. This can be done in many different ways, but here we will use the Python programming language. Python is very suitable for testing and prototyping because it has a REPL and many third-party libraries implementing functionality that we can reuse. In this case, we will use the PyUSB library to talk to the NXT.

聚光型空间太阳能电站的核心思路是通过特殊的聚光系统，一方面将太阳光集中汇聚到太阳能电池表面，提高光电转换效率；另一方面将发射天线发出的微波波束精准对准太空飞行器或地面接收站的天线。代表方案包括美国的“阿尔法”、中国的“欧米伽”等，其优势在于结构紧凑、重量较轻，但对热管理与指向精度要求高。
