Making blacktop white to cool the world

The Heat Island Effect is the tendency for hard surfaces to retain heat, releasing it at night. So cities don't cool down at night. Any school child knows that dark, black surfaces absorb more of the sun's rays. Our asphalt roads are one huge heat-battery snaking around town.

Now there is a solution. Paint the roads a light color.
