William Waldon:

The construction of the luna ring would more than likely take place in multiple phases, possibly through 2 generations. The first step is to set up an infrastructure to get the materials needed for the project into space which would include a space port that could robotically build ships in low Earth orbit.

It sounds so crazy futuristic, but at the same time it’s pretty amazing that something like this hasn’t been attempted.

Sounds better than heating stuff up as hot as the Sun… On Earth.
