Yeah exciting project.
I guess it will be an ongoing project for decades, much like the Space station is
however much bigger. The modules will be a lot larger in length, height and width I would imagine.
I have a sneaky feeling tho however they wont just be using solar power, I would think a small nuclear reactor would be used for essential projects, life support and emergencys.
Been a long time coming lets hope it happens. It's been a dream of mine for years to finally hear something like this. Hopefully it will be complete before my lifetime ends.
