This could be interesting (as I have also been looking for something to reduce CO2 and VOC in the home), but the important part is probably this:

> only require a visible light source that also produces heat—such as a halogen or incandescent bulb—and a lampshade coated with a thermocatalyst.

My read is that you wouldn't be able to do this with an LED, and I only use LED lights around the house. Isn't any heat production from a light is an inefficiency to begin with?
