The Illuminati Project Pushes For Dark Skies In 2009

An anonymous reader writes "2009 is the 400th anniversary of Galileo's observations of Venus, Saturn and Jupiter published in Sidereus Nuncius ('Starry Messenger'). To improve scientific literacy, the NOAO and NASA are promoting dark-sky initiatives in 2009 to draw attention to the problem of light pollution which obscures nearly all night sky colors and objects except for the moon and a few bright stars and planets. Project Illuminati is a Flickr project by James Cann to showcase the beauty of light pollution to raise awareness and educate fellow Earthmates to lower energy consumption and become more curious about our place in the universe."

      in fact, mirroring the light back to the ground instead of losing it to the sky, will make for more efficient lights. So just installing mirrors will brighten the streets!
      Installing lamps that are darker by the same amount, that they gain by reflecting everything to the streets, will make them exactly as bright as the old lights, while saving energy.

      First off, let's not pretend that light pollution is harmless to human health. The circadian system is at least in part regulated by the amount and type of light that our eyes receive. As for safety, there are several types. As far as traffic goes, street lights are generally positively correlated with safety at intersections, but lighting of roadways between intersections shows mixed results in the studies I've seen.

      Back to the main point of your post, though: crime. Ever heard of the Chicago Alley Lighting Project? In 1998, Chicago attempted to test this very theory: that increasing lighting of dark places would reduce crimes like rape and muggings. They took two eight-square-block areas, one for study and one as a control, and tripled the lighting in the study area. Guess what happened? Crime went *UP* in the test area, in all categories -- 77% for property crime, 32% for violent crime, etc -- an overall increase of 40%. The daytime crime rate in the study area dropped 23%. In the control area, nighttime crime only went up 19%, while daytime went down 21%.

      Overlighting an area makes the shadows appear darker and makes it easier for criminals to see what they're doing. Extra lighting makes people *feel* safer, but it usually doesn't make them any safer. For public safety, the goal should be not to make as much illumination as possible, but to even out illumination -- not too bright in the bright places, not to dim in the dark places.

    The shields over the lights have been shown to reduce the amount of light being thrown into the sky, but they also increase the amount of glare on the road. In order to be effective, the entire fixture head needs to be replaced with one that has been designed to cast the light downward in the right way, another cost for the muni to absorb.
    Legislation will do nothing to improve these conditions, it will likely pass costs on to the states or local government that they do not have the money to work with.

    First, you legislate it since its the only way to get it done. Sad but true. Next, you only need LED light bulbs. You don't have to replace the full lamp, at least if these consumer sites are anything to go by.

    If the cost of power and the cost of the bulb are figured in, the LED street lamps take an insane amount of time to recoup the cost. Even when you figure in the labor to replace the bulbs every couple of years it still doesn't add up.

    Per the source Wikipedia provided the extra initial cost is paid off within two years just from the electricity savings, and barring a physical disaster (such as the streetlamp falling over or getting shot with a gun) you don't have to change the bulb for 20 years. Really, it is a better choice but it would require work by city employees to actually make the change happen. They may even have to do a slide show!

    Hell yes I would advocate for this. Budgets don't magically get bigger on their own. You have to work for it. You have to plan and invest for it. This is a very, fucking, simple, means to save the city/town a lot of money and power, and it cuts down on light pollution as an added bonus!

    Oh and something else to chew on: as more demand for LED lights increases, in the form of cities and towns using them for streetlights, the manufacturing process will be improved as companies compete with one another to produce a cheaper light bulb to sell. That's basic market principles. Demand drives innovation. Yet another long term economic bonus by mandating a switch to LED lights.

    Apparently the Department of Energy in the US thinks they're a damn good thing that should be improved so they can become the defacto light source. They're hosting a contest since May 2008 to create a better LED light bulb. They call it the L-Prize.

    Really, once you look at the known facts and the future potential you have to ask yourself why not? A handful of employees might lose their job? Taxes may go up a fraction of a percent?
