White roofs catch on to save energy costs

I don't mean to make fun, but this sentence struck me as funny: "Relying on the centuries-old principle that white objects absorb less heat than dark ones"<p>As if before those "centuries" light and dark objects absorbed heat differently. :)

How about making them more reflective and aiming them at New England for a little winter heating help.

A friend who used to live in Florida told me they would put water on the roof in the summer. The evaporation of the water would cool down the roof and house.

My Toyota FJ Cruiser has a white roof and tinted glass, it seems to stay much cooler in the sun than any vehicle I had before.

What you really need is a roof is that is black in the winter and white in the summer.
