A incandescent bulbs more energy-efficient than LED

The biggest advantage of LED bulb is energy saving, but it is also very obvious shortcomings, it is not "warm." Are you sure you want to reduce the energy-saving bulb itself heat it? The answer is definitely not the case. Recently, the MIT research team proposed a new solution.

The MIT researchers have developed a new incandescent bulbs, the bulb can absorb heat from their own, those calories then converted into electrical energy to power lights. After this cycle, the new LED bulbs than incandescent bulbs more energy-efficient.

In fact, this new type of incandescent light bulb does not change the principles of traditional incandescent bulbs, the light bulb is only attached to the surface layer of the crystal filter. The role of this filter is: After the light emitted, then you can at the same time reflecting infrared waves to the filament, filament reabsorbed emitting light into electricity again. So it goes, ad infinitum, until the lamp is turned off.

But hear this, as a big fan of incandescent light bulbs should not be too excited. Currently this new incandescent bulbs exist only in theory, that possibility is not listed on the short term. However, research and development team said that for this theory into practice, they are still very confident.
