I've seen numerous ideas on here on ways to keep your driveway from freezing but none dealing with extremely hot driveways. In the Sun Belt of the country, it is always rough on the feet in the dead of Summer to walk out of your house bare footed when you have a concrete or asphalt driveway. I think that it would be great to have coils built under the concrete/asphalt in which cold water could be turned on and off to cool this before walking on it.
