[Pearls Before Swine]

Actually the filter/mirror is constructed by vacuum deposition of many alternating layers of materials.

I know, I browsed the paper.

Still, the effect of the composite device is that the radiation is no longer black body--as you say, it is concentrated in the visible range, because infra-red (most of the black-body curve at regular filament temps of about 2700 K), can't escape.

A brilliant (pun, sorry) idea. The practical questions, are cost of the layered envelope, and ultimate durability of the final composite structure. Will the filament hold up any better than it does with a traditional bulb?

The REAL question...

How many Mormons will it take to change this new fangled lightbulb?

Six

One to change the light bulb;
one to deny that there was any change made;
one to say that we shouldn't focus on the change--only the need for light;
one to say we don't teach that the light bulb needed changing in the first place;
one to say that the changer was acting for himself and not as an official changer;
and one to say "who cares who changed the bulb, don't you feel the burning of the light?

 

 

12,560,869   (the total Church membership according to the most recent Conference Report).

One prophet to propose it in General Conference, and 12,560,867 to sustain the motion and accept it as Scripture and as God's Will, and one to actually change the light bulb.

 

It depends...
If it is the Relief Society it takes four. One to fix refreshments. One to bring the tablecloth. One to design the Center Piece, And one to screw in the light bulb.
If it is the Bishopric, forget it, they don't do light bulbs. They call a Priesthood Executive Council And delegate it to the Elders.
If it is the Elders it takes four. Three that don't show up, and One to change the bulb.
If it is the High Priests it takes four. Two to push the wheel chairs. One to handle the oxygen tank, And one to screw in the light bulb.
If it is the Home Teachers, it only takes two, But you have to wait until the end of the month.
If it is the Aaronic Priesthood, it only takes one. He holds the light bulb in the socket And the whole world revolves around him.
