Michigan State University locally here did something very similar a few years back. They claim there's a thirty year payback but seeing as how we live in the second cloudiest city in America I am skeptical. However I cut them a little slack because universities are first adopters driving science forward even when the ROI isn't always there. But we get a lot of snow here and it is really nice to come out after it's snowed and not have to clear the snow off your car!
