Good restrooms, merry gentlemen!

"It all began with an idea to do something other than an old, tired, traditional card to wish our customers a happy holiday. It seemed rather fitting to do something more light-heartened and entertaining...an idea that revolved around music and holiday lighting...oh, and porta potties of course." [more inside]

"the horrible things that come for us when everything goes dark."

Drowning In Light
n 1996, Yale economist William D. Nordhaus calculated that the average citizen of Babylon would have had to work a total of 41 hours to buy enough lamp oil to equal a 75-watt light bulb burning for one hour. At the time of the American Revolution, a colonial would have been able to purchase the same amount of light, in the form of candles, for about five hour’s worth of work. And by 1992, the average American, using compact fluorescents, could earn the same amount of light in less than one second. That sounds like a great deal. Except for one thing: We treat light like a drug whose price is spiraling toward zero.

The Light that will Be

After Michael Mann set out to direct Collateral, the story’s setting moved from New York to Los Angeles. This decision was in part motivated by the unique visual presence of the city — especially the way it looked at night. Mann shot a majority of the film in HD (this was 2004), feeling the format better captured the city’s night lighting. Even the film’s protagonist taxi needed a custom coat to pick up different sheens depending on the type of artificial lighting the cab passed beneath. That city, at least as it appears in Collateral and countless other films, will never be the same again. L.A. has made a vast change-over to LED street lights, with New York City not far behind.

Lights Out, Luthor. I said...LIGHTS OUT!

January 1st, 2014 ushers in a new era for the U.S. population, as 40 and 60 watt incandescent lightbulbs will no longer be produced nor imported into the mainland. This turnaround follows the demise of non LED/CFL 75w bulbs on January 1st, 2013, and 2012's phaseout of 100 watt bulbs under the revised provisions to the National Energy Law of 1978. The ultimate catalyst for the greening of America? The 1973 Oil Crisis.

Slug bugged

Consumption of lungworm snails can transmit the lungworm parasite Angiostrongylus cantonensis, which can cause meningitis in humans and respiratory problems in dogs, which can eat afflicted slugs while running through open fields. Researchers at the University of Exeter hooked up LEDs to these snails to study their nighttime movements through gardens and how those movements might help them act as a vector for the parasites.

Incandescent lightbulbs banned

Incandescent lightbulbs are now banned across the entire European Union as of September 1. "Concerns about poor performance of replacement bulbs have been proved wrong." It is predicted to save 39 terawatt-hours of electricity across the EU annually by 2020. "The phase-out has been very smooth." BanTheBulb said "..the vast majority of the public have adjusted to using the next generation of lighting technologies with the absolute minimum of fuss and drama." [more inside]

HP-01 calculator watch

"Time: elusive and immediate...limited yet infinite. Because time is important to you, Hewlett-Packard introduces the HP-01, a new dimension in time management and personal computation." Truly, such an important model number could only be bestowed upon the king of all early calculator watches. No less than three batteries were required (two for the LED display alone), and even HP's impressive engineering was unable to save the HP-01 from the curse of bulkiness; it did not sell well at the $650 price point. The HP-01 was discontinued in 1980, as inexpensive LCD calculator watches began flooding the market (don't lie, you know you had one).

Turn off the lights when you leave.

The end of the light bulb? E. Fred Schubert, a professor at Rensselaer Polytechnic Institute "claims to have invented a 99-percent efficient reflector that promises to speed the replacement of light bulbs with LEDs." According to researchers, this could happen within the next five years. The current prototype is bankrolled by the ARPA and The National Science Foundation "recently award Schubert's team a $210,000 grant to create in three years a commercial version of his patented omnidirectional reflector."

"Schubert claimed that lighting accounts for 25 percent of U.S. electrical energy consumption. Since white LEDs emit more light per dollar and generate less unwanted heat, they are potentially a major energy saver."

Meanwhile, some of the oldtimers seem to be pretty refractory.

"Arrr, matey, insecure transaction off the port bow!"

"Arrr, matey, insecure transaction off the port bow!" Data can be stolen as it is transferred by recording and interpreting the flashing of LED lights on your equipment. Theoretically, then, your data isn't safe within viewing distance of a telescope, unless some engineer comes up with an ingenious workaround.
