Kinda reminds me of my dad asking me why I wanted him to pay to heat the outdoors if I left the door open when I was a kid.
Also, I have to wonder what happens if the runoff is not managed well - seems like you would be trading one ice problem for another once the water runs off the heated section onto an unheated section.
