Lunar Solar Power Generation -LUNA RING-

Lunar Solar Power Generation -LUNA RING-

The Energy Paradigm Shift Opens the Door to a Sustainable Society

A shift from economical use of limited resources to the unlimited use of clean energy is the ultimate dream of all mankind.
The LUNA RING, our lunar solar power generation concept, translates this dream into reality through ingenious ideas coupled with advanced space technologies.
Virtually inexhaustible, nonpolluting solar energy is the ultimate source of green energy that brings prosperity to nature as well as our lives.
Shimizu Corporation proposes The LUNA RING for the infinite coexistence of mankind and the Earth.






How Lunar Solar Energy Reaches the Earth

Transmitting Energy from the Moon to the Earth

The Solar Belt Made from Lunar Resources -Constructing a lunar solar power plant-

Exploiting Lunar Resources


Lunar resources will be used to the fullest extent possible in constructing the Solar Belt.
Water can be produced by reducing lunar soil with hydrogen that is imported from the Earth. Cementing material can also be extracted from lunar resources. These materials will be mixed with lunar soil and gravel to make concrete. Bricks, glass fibers and other structural materials can also be produced by solar-heat treatments.


Robotic Construction

Robots will play a vital role in construction on the lunar surface. They will be tele-operated 24 hours a day from the Earth.


Construction and resource extraction
Robots will perform various tasks on the lunar surface, including ground leveling and excavation of hard bottom strata.


Assembling units in space
Machines and equipment from the Earth will be assembled in space and landed on the lunar surface for installation.

The Solar Belt along the Lunar Equator

The Solar Belt Configuration1. Lunar solar cellsTo ensure continuous generation of power, an array of solar cells will extend like a belt along the entire 11,000km lunar equator. This belt will grow in width from a few kilometers to 400km.2. Electric power cablesThe cables will transfer the electric power from the lunar solar cells to the transmission facilities.3. Microwave power transmission antennasThe 20km-diameter antennas will transmit power to the receiving rectennas. A guidance beacon (radio beacon) brought from the Earth will be used to ensure accurate transmission.4. Laser power transmission facilitiesHigh-energy-density laser will be beamed to the receiving facilities. A guidance beacon (radio beacon) brought from the Earth will be used to ensure accurate transmission.5. Transportation route along the lunar equatorMaterials needed for the construction and maintenance of the Solar Belt will be transported along this route. Electric power cables will be installed under the transportation route.6. Solar cell production plantsThe plants will move automatically while producing solar cells from lunar resources and installing them.
