It’s year 2050 and within 10 years, all fossil fuels will be used up. All countries signed an agreement to approve an international construction, described as follows:
A track will be built on the equator, so something like a round railway will be constructed. It’s flat, so mountains on the equator will be flattened. Part of the seas/oceans will be reclaimed. It’s almost frictionless, so wheels can move on it easily. A similar track will be constructed on the Moon.
Solar panels are placed on the Moon, covering over 90% of its surface. The remaining area is used for maintanence, as well as the track.
A thick (perhaps, really thick) wire is constructed, perhaps with the help of airplanes, satellites and space shuttles, so that the tracks on the Earth and the Moon are connected. The wire may look like a thick pole when viewed on Earth, but when we scale down everything it should look only something like a set of electrical wires. At the two ends, wheels are installed, so the wire can move on the track like a train.
All materials used conduct electricity (perhaps with a plastic coating if there’s any safety concern).
All countries are going to work together, so money is (probably?) not a concern, and selling electricity earns money anyway.
All countries have the responsibility to maintain the system. I assume that no one deliberately damages the system.
Flying organisms around the wire are monitored, so they will be killed or brought away before getting close to the wire.
It’s up to the civil engineers of this project to decide the details of the system, for example, how wide the track should be, how thick the wire should be, etc. All of them are well-educated.
There is no aesthetic concern, so it’s okay for the system to look ugly as long as it supplied electricity.
Is this feasible? Any practical difficulties that we are unable to overcome?
