Nikola Tesla dreamed of sending electricity without wires. It never happened on Earth. Now Chinese scientists have a new plan. They want to use laser beams on the moon. Their idea focuses on the moon's south pole. Some areas there have constant sunlight. Others are in permanentpermanent/ˈpɜːrmənənt/L2永久的，长期的lasting for a very long time or forever shadow. These dark areas may contain valuablevaluable/ˈvæljuəbl/L2有价值的，宝贵的worth a lot of money or very useful water ice.
Future lunar roversroversL1探测车rovers will explore these dark craters. They cannot use solar panels there. However, laser beams can send energy from sunny peaks. Scientists from the Harbin Institute of Technology tested this idea. They used data from a NASA map. The team adjustedadjusted/əˈdʒʌstɪd/L2调整，调节changed slightly to make something work better the positions of laser stations by about 100 meters. This increased the network's effective coveragecoverage/ˈkʌvərɪdʒ/L2覆盖范围，覆盖the amount of space or area that something covers by more than 35 percent. As a result, the powered areas became almost fully connected.
The scientists wrote, "The study provides theoretical support for the construction of lunar research bases." The system can send about 371 watts of power over 5 kilometers. This is enough to run a rover in the dark. In addition, the team plans to study using the laser for both energy and communication. This will help solve data challenges on the moon.
