I have seen far smaller estimates, 300x300 km area for entire world (current consumption) in Sahara, or 125x125 km area for Europe. Dunno about credibility, was in a newspaper article related to some German investors building large solar farm in Sahara.
I actually think that the 125x125km area should be doable. Its not like we don't have space in Sahara. US is more difficult as its probably not practical to transfer electricity as it from Africa. Maybe as hydrogen, dunno.
