thats because the roads currently are black ... have you ever seen a white road
The thread is about painting
roofs not roads but yeah one thing I remember about my town of origin, Lithgow, is that they had a white road (concrete) as opposed to bitumen, and lots of coal dust and soot in the air.....but the road stayed white.

You've confirmed to me that you are an idiot if you believe this mumbo jumbo is possible.
Really, are you denying that white is more efficient in reflecting heat than other colours? Why are solar panels black Doc?

Sure, so long as you don't have to come up with the price tag or think about the details. Just wave your arms in the air and tell everyone you have a magic bullet that costs 'bugga all'.
Well FD the cost is bugga-all
if its just about choosing a colour when roofs are first constructed or when they are replaced. It's not about ripping roofs up and replacing them just to change the colour.
As the linked article SAYS........
Quote:The researchers believe that it would be cheap and easy to increase the albedo of cities by applying the reflective materials when roofs and roads are routinely resurfaced, rather than doing it as a special measure.
