Nikola Tesla would not be impressed.
Cool! What a bright idea.
Thanks for the chart. I was thinking of practical lighting for the home.
also this:
"The Vanderbilt researchers are the first to report making quantum dots that spontaneously emit white light, but they aren’t the first to report using quantum dots to produce hybrid, white-light LEDs. The other reports – one by a group at the University of St. Andrews in Scotland and one by a group at Sandia National Laboratories – describe achieving this effect by adding additional compounds that interact with the tiny crystals to produce a white-light spectrum. The magic-sized quantum dots, by contrast, produce white light without any extra chemical treatment: The full spectrum emission is an intrinsic effect. "
Example. "How many pollacks does it take to got ( screw in light bulb) stir quantum dots into polyurethane and coat a blue LED light.
(grab slide rule pocket)HAR HAR HAR
"A stupid question from someone with no technology aptitude. How does one turn the light off, particularly on the silverware example?
Better still, what happens if one were to swallow one of those dang things?
This is why I continue using vacuum tubes. There is nothing like them.
Oh my God, then how is anyone going to know when I have an idea?
lol
How much power plant electricity goes to lights as opposed to other uses?
If these lights allowed us to reduce the demand for electricity for light usage by 90%, how much impact would it have?
Would it have a significiant impact on the demand for oil? the demand for natural gas?
There would be some offsetting trends, people would leave lights on more, there would be more outside lighting, etc.

Good chart - thanks.
Personally, the one thing I liked was 'led lights don't produce heat' That would seem to indicate that you could have savings in other areas, maybe not in a home, but in industry that uses lights 24/7 and also cooling. Less energy to produce the same light combined with less heat...would there also be energy savings in the cooling? Perhaps not significant in one place but if all industry did that? I don't do science, I just ask questions and let those knowledgeable in the area tell us :)
That's obviously a "good thing", as I've used white LEDs as spectoscopy sources, and in various flashlights, and the current "cool blue white" isn't really practical for "everyday" lighting use.
