Somehow this actually looks physically plausible, and it's been forever since I've seen a new design for a Dyson ring that could be considered as suchOnly thing I'm wondering about is how would the atmosphere be held in placeIt would be neat to travel from one disc to another (through those three "bars" I assume) and be able to look back on the ones you've just been to. With different ones designed for different purposes, from practical farming discs to luxury holiday discs - you could get anywhere which much less stops along the way than you would travelling around on Earth. Great concept!
