Producing electricity on the Moon at night

Scientists have proposed a system of mirrors, processed lunar soil and a heat engine to provide energy to vehicles and crew during the lunar night. This would preclude the need for batteries and nuclear power sources such as those used by the Chinese rover that recently landed on the moon. The lunar night lasts approximately 14 days, during which temperatures as low as -150 ºC have been recorded. This complicates vehicle movement and equipment functioning on the lunar surface, requiring the transport of heavy batteries from Earth or the use of nuclear energy, as exemplified by the Chinese rover Yutu.
