Lunar Light

I live in downtown DeLand, on a busy street with streetlights, it seems, every few feet (two on my small property zone alone). I've never understood why we have so many lights, generally speaking: Walking at night along a dark beach or a quiet road, I'm always struck by how little artificial light is really necessary to navigate and feel safe, especially when it's clear. My son is into stargazing, and a month or so ago we spent a new-moon night at Woodruff Preserve stargazing with the local high school astronomy teacher. It was as dark as one could imagine, but we had no navigating the alligator-infested, boggy area.

I have also noticed how street lamps, while illuminating their narrow radius, cast deep shadows at the periphery. It seems to me that outdoor lighting, which makes our eyes so less sensitive to ambient light at night, makes areas more dangerous: The perfect place to hide for a thug would be the wells of darkness beside houses and overgrown lots, taking advantage of our purblindness.

Give me full darkness any night.

Anyway, this entry's not technically on gardening, but it's Earth Day, and I often dwell here on the intertwined issues of sustainability, localism, and the need to appreciate the beauty of the world around us. Click through to read about a civil engineering idea that would change outdoor lighting for the better: "What if streetlights could respond to ambient moonlight, dimming and brightening each month as the moon cycles through its phases?...." But what was most striking was this (unsubstantiated but unsurprising) assertion:

Lunar Light: Perhaps the most fascinating fact that the collective’s research revealed, however, is a little-known detail about the history of electricity: in the 1930s, with the spread of electrification and the consolidation of utilities, streetlights became a convenient way to off-load excess energy from the grid at night, when power demands dropped significantly. This intentionally inefficient system determined the norm for nighttime outdoor lighting levels, a standard that has not been revised since, even though the need for off-loading ended in the 1970s. What we now assume is a safety measure is in fact the forgotten remnant of an obsolete energy practice. Next Gen juror Fred Dust, head of IDEO’s Smart Space design practice, says the jury found this part of the proposal both shocking and compelling. “It’s such an archaic concept that it seems like science fiction,” he says.

Questioning current lighting standards and asking what level of illumination is actually necessary brings some sur­prising answers. Willis explains that the human eye, with its com­-ple­mentary systems of rods and cones, evolved to adapt to both full-sun days and moonless nights. “We can see an incredibly broad range of intensities,” he says. “The difference between sunlight and starlight is something like a hundred thousand orders of magnitude.” Bright moonlight is in"

Florida Counties Try to Contain Phosphate Mines - New York Times

Your corrupt, corporatist and inept federal government, looking out for the best interests of the highest bidder. If this kind of thing doesn't rile you, then WAKE UP.

Florida Counties Try to Contain Phosphate Mines - New York Times: "Two large companies, Mosaic Fertilizer and CF Industry Holdings, operate most of the open pit phosphate mines in Hardee and Polk Counties... The mines pump on average more than 100,000 gallons of water a minute, according to the Florida Institute of Phosphate Research, an industry-financed organization.

The Environmental Protection Department regulates the mines. The counties say that state officials have granted too many mine permits and that many permits do not meet federal standards.

Mining companies have been allowed to destroy streams and wetlands, according to the counties, and areas they have reclaimed remain damaged and scarred.

“We found out through consultants that none of the permits complied with the environmental regulations on the books,” the natural resources planner for Charlotte County, Bill Byle, said. “We thought all these agencies were protecting us.”

A study by the Environmental Protection Department found that the forestland in the Peace River Basin had declined, to 17 percent from 60 percent in 1940. Wetlands declined to 16 percent from 25 percent

FPL Group, Boca start-up join in ethanol fuel project -- South Florida Sun-Sentinel.com

FPL Group, Boca start-up join in ethanol fuel project -- South Florida Sun-Sentinel.com: "A tiny Boca Raton start-up got a big boost on Thursday from FPL Group, which will partner with Citrus Energy LLC to make ethanol from discarded orange peels.

The two firms will build a first-of-its-kind plant designed to produce 4 million gallons of ethanol a year to be blended with gasoline for vehicle fuel.

'It's great news,' said David Stewart, a former computer engineer who founded Citrus Energy last year. He said that the state now has very little ethanol in its gas. 'This would be a start in Florida.'"
