Wait, I thought climate change was from CO2. Now the materials used to build cities is contributing, too?
The LA Street Services began rolling out the project last May, which preliminary testing shows has reduced the temperature of roadways by up to 10 degrees. The project involves applying a light gray coating of the product CoolSeal, made by the company GuardTop.
So where does the energy go, that used to be absorbed by the pavement? Perhaps the energy is destroyed by the CoolSeal, or converted into unicorn food?
"CoolSeal is applied like conventional sealcoats to asphalt surfaces to protect and maintain the quality and longevity of the surface," according to the company website. "While most cool pavements on the market are polymer based, CoolSeal is a water-based, asphalt emulsion."The water evaporates, leaving the asphalt - you know, that icky fossil fuel stuff?
While each coasting could can last up to seven years, they are also pricey, with the estimated cost of $40,000 per mile, the L.A. Daily News reported.
I can't seem to find anything about this magical product at the company's website. Maybe someone calculated the energy 'savings'?
