Solar-powered light emitting cement developed


Washington: Scientists of Michoacan’s University have developed a new-light emitting cement that could last 100 years and illuminate roads, highways or bicycle lanes at night by absorbing solar energy during the day. The cement exists in blue or green color and the light intensity can be regulated to avoid dazzling drivers.

Jose Carlos Rubio, from Michoacan’s University of San Nicolas Hidalgo (UMSNH) in Mexico said “The main issue was that cement is an opaque body that doesn’t allow light yo pass to its interior. The common cement is a dust that when added to water dissolves like an effervescent pill. In that moment it starts to become a gel, similar to the one used for hair styling, but much stronger and resistant; at the same time, some crystal flakes are formed, these are unwanted sub-products in hardened cement.”

Morning, the building, road, highway or structure that is made out of this new cement can absorb solar energy and emit it during the night for around 12 hours, researchers said.
