I respectfully disagree.
*Our researchers cleverly implied that
changing the thickness of a metal oxide layer (and the resulting

in the light bulb but the two effects are quite different and
have nothing to do with each other, IMHO.

The filament is in a vacuum. Heating it does not cause it's
surface to mix more readily with oxygen because there is no
oxygen to speak of, in the vicinity of the filament.


I did not note any reference to " metal oxide layer "



So if one modified the surface of the filament so
that it would radiate less IR and more visible light, the light bulb
be more efficient.

Theoretically, I agree. *This isn't what our researchers were doing,
however.


Hmmm. I thought the whole article was about how the researchers were
modifying the surface of the filament.
