Lightway is a window and lighting system based around the existing Breezway window louver system.

The major difference being the Lightway uses organic OLED's and advanced transparent Photovoltaic Nanoscale technology to allow sunlight to enter the household during the day and to fill the house with light during the night.

Lightway is essentially a modular light that absorbs solar energy during the day, using it a night to illuminate an area as if it were daytime again.

The entire system is transparent and extremely efficient. There is also a portable application to the system.
