It would have to be at geostrationary orbit
That's wild. I wonder if they all went to the same art school... Their styles have an uncanny similarity.
Eh, geostationary orbits put the object at the same point relative to the earth, but what we want is it to always be between the earth and sun, basically with an orbital period of Geo requires an orbital period of 24 hours, but we want a period of one year. The best way to do that is probably to put the object at Lagrange point 1, or L1, which is a point where gravity is balanced in such a way that an object will stay perfectly stationary between the earth and sun. Well, L1 is technically an unstable lagrange point compared to Ll4 and L5 and would require small scale corrections but if you have big mirrors and some motors, you'll be able to make minor course corrections by angling the mirrors a bit to take advantage of light pressure from the sun. You could probably get away with very minimal station keeping fuel over very long periods too.
