Play LEDs plus Solar cells make a well-lit world
Ever wonder how a stoplight works? We all know they never work precisely how we want them to, but what about their innards? I head to the factory of Carmanah Technologies for some hard workobservation (I hate getting my hands dirty). Carmanah combines solar energy and LEDs in order for planes and ships to traverse the planet safely. We can also thank them for those metering lights getting onto the freeway on our way home.
