Photonic Structure Increases Light Bulb Efficiency

Posted by Hemos on from the bulb-bulb-burning-bright dept.

An Anonymous Coward writes "A new experimental microscopic tungsten lattice can increase the efficiency of an incandescent electric bulb from 5 percent to greater than 60 percent. This is done by converting waste heat into visible light. "

    This would make for an incredibly cheap and effective night vision system with a small battery and a CCD camera. IR floodlight with 60% efficiency... mmmmmm.

    This is great work. But if people want high-efficiency, pleasant-looking light-bulbs, they can already get them and save money in the process. The fact that people don't buy them despite all their advantages suggests that the problem isn't technology, it's people.
