Virginia,
The only thing I have found similar was in
Luck and Consequences by Bob Bartholomew. Bob had Bernie find the source of Clark's power in attempt to explain why he and Lois could not have children by inventing 'Kryptonian Extensions", nano-technology that binds to Clark's cells and processes sunlight into super powers. That story and how they got around it
is a great read but
Bernie/Bob explain it best.

So basically Debbie is not breaking totally new ground but who knows where she will take it. In this story Kara was found at night, taken to the hospital, kept inside, taken by car to Emily's house, kept inside, and now is sleeping. The poor girl has not had any sunlight in probably a couple of days and the Kryptonian Extensions (Bob's naming) are probably starved. However when they get sunlight, who knows???
