According to various sources, Dr José Carlos Rubio from the Michoacan University of Saint Nicholas of Hidalgo in Mexico has created a light-emitting cement that is designed to illuminate roads, pavements and bicycle lanes without using electricity.
The cement absorbs solar energy during the day and releases it in the dark. The product is claimed to have a lifespan of 100 years.
Rubio explained that when water is added to common cement, crystal flakes are formed that block the absorption of solar energy. The researcher focused on modifying the micro-structure of the cement in order to eliminate the crystals.
Rubio claims this new cement is sun resistant, contributing to its estimated 100 year lifespan.
Currently, the material is available in blue or green, and the light intensity can be regulated to avoid dazzling drivers or cyclist, or unnecessary glare.
