Return of incandescent light bulbs as MIT makes them more efficient than LEDs

Just found this, 40% efficient incandescents lol. Not as efficient as diy leds, but still crazy.

"Researchers at MIT have shown that by surrounding the filament with a special crystal structure in the glass they can bounce back the energy which is usually lost in heat, while still allowing the light through.

They refer to the technique as ‘recycling light’ because the energy which would usually escape into the air is redirected back to the filament where it can create new light.

"It recycles the energy that would otherwise be wasted," said Professor Marin Soljacic."

I would replace my cfls with those in a heartbeat.

The efficiency numbers mentioned in that article do not square with numbers I've learned from other sources. Still, it looks promising.

Lol they would be more efficient than hps, so I think that a lot of people would be replacing hid setups with these.

Yeah I couldn't tell if it is legit or not, but definitely looked interesting.
