"lighthouse on the moon" - what ?

Honeybee Robotics plans to build massive lighthouses on the moon to provide light, power, and communications infrastructure, aiding the development of a lunar economy. Named LUNARSABER (Lunar Utility Navigation with Advanced Remote Sensing and Autonomous Beaming for Energy Redistribution), this concept has been selected by DARPA's LunA-10 program. The 330-foot (100-meter) tall tower will feature solar panels, power storage and transfer, communications, navigation, timing, and surveillance capabilities.
