I ache, therefore I am
Every week I do something new to reduce light pollution. Eyes on the Sky is at 600,000+ views so far; more views = more awareness. Please consider sharing with others.

Quote:I don't care for the blue spectrum of it - maybe that can be altered - but I sure like how much less light it seems to give off, while still illuminating the pathway. I'd like to know more about it though.
Quote:That's a cool article--I'm glad you posted it. It looks like a good idea. It will be interesting to see what kind of cumulative reduction affect it will have on light pollution and that darn city halo. It seems like an idea that can cut done on electricity and light pollution at the same time.

For a city/county to cover a pathway or sidewalk would be prohibitively expensive and it would only last 5 years at the most.I'd be surprised to see this anywhere other than some private attractions and homes.
Quote:I can see that most folks here are not thinking the matter through fully when voicing support for the concept.In no way would it offer any advantages for those of us in the astronomy community. Rather, it could only markedly add to light pollution. The general public would never accept replacing conventional outdoor lighting with softly glowing path and walkways under any circumstances. Instead, you might more likely see this sort of a coating applied for the purpose of illuminating every residential drive way, etc. IN ADDITION to still having conventional exterior and garden lights, as softly glowing landscape features are in no way any sort of substitute for illumination that will light up an entire property, as most home owners seem to like today.In addition, all the subtle glow produced by this coat is directed upwards. While the addition of a few hundred yards of coated walkway might not be found unacceptable, should the practice become widely accepted the combined illumination from say thousands of residential driveways in the suburbs could be disastrous for us.BrooksObs
