There is a Lincoln, Nebraska-based company called Axis Technologies (AXTG.PK) that has been helping cities and public buildings across the country "go green."
To save money, the buildings use solar harvesting technology that automatically adjusts the amount of electric current in a light fixture.
Dubbed a "ballast," this electronic component can regulate voltage, thus using up to 70% less energy than traditional lighting. When windows or skylights provide natural daylight to a room, the Axis Ballast uses integrated automatic photo sensors capturing the light to dramatically reduce energy consumption.
Axis Technologies was nominated for the 2007 Chicago Innovation Award, as well as featured in BusinessWeek as one of '10 Green Technologies That Could Change Your Life.'
