That's interesting. I wonder how that will affect the car on a hot day?
Will it cause more heat (as the material is designed to encourage the conversion of light into heat)?
Or will it reduce the heat (as most of the easily convertible wavelengths get converted on the surface of the car, not on the dashboard)?
Or (as I suspect) will it have next to no effect either way?
- rbanffy 8y agoMy guess is that it converts part of the incoming light into heat and radiates that in both directions. The fraction of light that is absorbed inside the car and then radiates, but don't radiate through the window, is smaller than it would be if nothing was absorbed by the windshield, so I guess it'll be cooler inside the car. But nobody should trust my math in those matters (because I didn't do any)
