Solar panels on the moon could one day power Earth
|
view preview
Architectural and engineering firm Shimizu plans to solve Earth's climate crisis by building a band of solar panels 400 kilometres wide along the entire 11,000-kilometre equator of the Moon. The energy generated will be beamed back to Earth in the form of microwaves and converted into electricity at ground stations. The team hopes to start building the "Luna Ring" from Moon materials in 2035.
