This works by heating a thin tungsten wire to temperatures of around 2,700 degrees Celsius.
Thats why country after country has banned or is phasing out the inefficient technology.
It recycles the energy that would otherwise be wasted, said Professor Soljacic.
But this new two-stage incandescent the MIT team is working on could raise efficiency up to 40 percent.
And it shows colours far more naturally than modern energy-efficient bulbs.
An important feature is that our demonstrated machine achieves near-ideal rendering of colours.
In addition to returning the warm glow of incandescent bulbs to the living room, Professor Solja?i?
believes that infrared-reflecting structures could have applications in a number of different energy systems.
you’ve got the option to read MITs paper on their new approach to incandescent bulbshere.
