Legend has it that at the end of every rainbow is a pot of gold hidden by a leprechaun. In the laboratories of the Renewable Energy and Environmental Research Centre, they have struck gold with luminescent solar concentrators (LSCs), which use certain colours from sunlight to produce elettricity. The warmest of them (red, orange and yellow) they use to make our surroundings more comfortable.
This research yielded the Eni Ray Plus® technology, employed in Domal's Smart Window. Produced from transparent panels made by Arkema (containing suitable dyes from Eni laboratories), the Smart Window can charge a battery that, hidden in the frame, feeds a series of sensors that monitor internal and external temperature. This lets it automatically move the shutters installed in the double-glazing and ensures the surroundings are warm and well lit.
