This is a great concept. The trick is to time coffee intake just prior to your nap so that by the time it kicks in you're done with your nap. A 15 minute nap seems to be what they're talking about and I doubt that you could make it an hour unless you're really exhausted to the point where a caffeine hit won't pull you out of slumber. I'm going to try this myself especially if it's a day where I got no sleep.
