Tomato help, please!

Tomato help, please!

Hi, everybody. *waves* I live in Minneapolis and I have a ginormous tomato plant with at least 50 flowers (I stopped counting at 50) but absolutely no fruit. Not even teensy tiny ones. I want to give this plant time to finish producing. My roommate suggested transplanting it into a large pot and moving it into our glassed-in porch. Has anybody ever done that successfully?? I guess the other option is some kind of cold frame, but this plant is five feet tall. (Seriously. It's almost as big as I am.) That's a lot of cold frame to build for somebody with no skill at building things. Suggestions? Help! P.S. I have other plants with ripening fruit so I don't think this is a pollinator problem. Is there a way to check?
Lots of pictures!
