The Shimizu Corporation's "Luna Ring" proposes constructing an array of solar cells around the Moon's equator, about 11,000 km (6,800 miles), to harvest solar energy and beam it back to Earth.

Nine will air Earth to Luna, which follows the adventures of a six-year-old who is passionately in love with science, on its free-to-air multichannel 9Go! from later this month.

All five seasons of Earth to Luna!, an International Emmy-nominated preschool animated series, have been picked up by Nine in Australia.
