This highway can be quiet, bright and full of energy

Researchers at the Eindhoven University of Technology have developed a system that has the potential to kill two birds with one stone: large colourful noise barriers for highways that also generate solar energy.

“They are basically large luminescent solar concentrators (LSCs),” Michael Debije, from the university’s Department of Chemical Engineering and Chemistry, told CNBC via email.

“That is, they are large sheets of plastic filled with a fluorescent dye,” he added.
