Despite common cartoon knowledge, it's actually quite difficult to have new ideas about lightbulbs. That's why this concept from Mahendra Chauhan and Sanjay Rajput is so surprising—it obviously took twice as much brainpower to conceive it. 
The idea is simple: put two filaments inside a bulb instead of one. When the first one burns out, give the bulb a half turn and use the second filament. Sounds great to me—now where's our light bulb engineers to tell us why this wouldn't work?
In Design Boom's RE-think RE-cycle competition, Mahendra Chauhan and Sanjay Rajput from India propose a novel, extremely TreeHugger way to double the life of the common lightbulb.
Their concept: a typical lightbulb is 35 grams, 0.5 grams of which is the tungsten filament. The tungsten fails, the bulb is pitched, 35 grams of materials out the window. Add an extra filament and 2 extra contacts and when the first filament fails, you can rotate the bulb 90 degrees and get a whole other lifetime from the same bulb.
