This is, technically, idiotic. The solar heating of asphalt is extremely low grade energy. No, a road does not actually get hot enough to fry and egg on. It gets hot enough that you can barely stand to walk on it which is about 140-150 degrees F max. That is not hot
Ever been to Texas? I've seen it done- of course, I must admit that they used a black iron frying pan, but nonetheless, I have seen an egg fried by the sun.
