Snow and LED traffic lights

January 8, 2010

Lynne Kiesling

The snowy weather across much of the northern hemisphere this week is being disruptive in many ways. At the Freakonomics blog, Eric Morris highlights one unanticipated and unintended disruption — snow obscuring energy-efficient LED traffic lights:

The biggest weakness of LEDs is their biggest strength – they don’t radiate much heat. What on earth could be wrong with that? Depends on which part of the earth you inhabit. In the upper Midwest, LEDs can have deadly consequences.

LEDs’ energy conservation creates a problem in case of a – literal – perfect storm. Low temperatures, wet snow, and driving wind can coat – and obscure – traffic signals. Traditional bulbs throw off heat which melts the snow. LEDs don’t. The result is intersections without visible traffic lights which are hazardous and sometimes deadly, as was recently the case in Chicago.

The principal tradeoff in this example is between energy efficiency/cost/environment and safety while driving. I hope that one of the commenters is correct and that there are straightforward engineering approaches to minimize this tradeoff. My initial thought was downward-slanted shields around each light, both to keep the snow off of the light directly and to take advantage of gravity to prevent the snow from accumulating on the fixture.

Ten words you need to stop misspelling

Lynne Kiesling

The Oatmeal is a great one-man operation with outstanding, witty visual representations of a range of topics, including 10 Things You Need To Stop Tweeting About. For this one he earns my undying gratitude:

10 Words You Need To Stop Misspelling

Love.Love.Love. Will be sharing with all of my students. I wish I could copy it onto a card and hand it out on the street, like some grammar evangelist. His explanation of the differences among the homonyms “their”, “they’re”, and “there” is hilarious. But I don’t know what he’s got against dolphins …

Wolfers on cheap economists and comparative advantage

January 6, 2010

Lynne Kiesling

Count me among the economists who enjoyed the Wall Street Journal’s funny article about how cheap we are. But I also get a lot of pleasure out of trimming the Christmas tree, so I’m not inclined to be so stringent in following comparative advantage that I want to hire someone to do so. I do, however, agree with Justin Wolfers that hiring someone to take it down is very, very appealing. Instead, though, the KP Spouse is bribing me with pizza to do so this evening.

Henderson on WSJ on Mexico and drug violence

January 6, 2010

Lynne Kiesling

Ever since David Luhnow’s article in the Wall Street Journal on how drug legalization in the U.S. could reduce the horrific violence going on in Mexico right now, I have been mulling over writing about it. Happily, David Henderson has done so at Econlog, and much of his commentary is along the lines that I’ve been thinking.

… the demand for illegal drugs from Mexico would decline. The reason is simple: the implicit tax in the U.S. would fall to zero. The implicit tax imposed by the Mexican government would stay high. It’s as if the U.S. government was imposing both a tariff on imports, a tax on domestic production, and a tax on domestic consumption, and then suddenly ended the tax on domestic production and the tax on domestic consumption. The amount demanded would rise because of the lower tax, but domestic production, suddenly facing a much lighter tax burden, would be advantaged relative to imports. Therefore domestic production would rise, crowding out imports. The net effect on imports is likely to be negative. So, yes, the supply chain in Mexico would be illegal and organized crime would be the supplier, but they would supply less to the United States, the main area of consumption.

Not only would they supply less, but because they would be competing with suppliers charging lower prices (presumably), their revenues would fall as well as their quantities sold (note also that this result reflects the reasonable assumption that the demand would be inelastic, in which case prices and revenues move in the same direction). That revenue hit is where the real power to undermine drug gangs lies.

The rest of David’s analysis is excellent and worth a read.

Oregon Scientific’s elegant in-home energy monitor

January 5, 2010

Lynne Kiesling

The Consumer Electronics Show has started, and we device and gadget geeks are having fun! One thing I noticed quickly is in this Engadget post about Oregon Scientific’s new device offerings:

Look at the device on the far right — it’s a wireless appliance manager “to help users keep an eye on how much energy up to eight appliances are using”. Look at how elegant it is! Clean, simple interface, shows the energy costs by appliance and a total energy cost for all of them, boom, done. It would probably not require much programming to make it transactive, so that the homeowner could choose trigger prices by appliance to make the appliances themselves price responsive.

That’s what I’m talking about when I effuse about the potential for in-home energy management technology. Clean, elegant design, transactive (or, in this case, potentially transactive) functionality.

It’s early in the CES; there’s more of this to come.

… goes to Tunku Varadarajan, in his Daily Beast column today about terrorism and air security:

Of course, it may be that the one way to ensure a grassroots Democrats clamor for action against terrorism is to call it “anthropogenic”…

Hah, climate policy humor!

Another early music fan

January 1, 2010

Lynne Kiesling

Imagine my delight upon perusing the Volokh Conspiracy earlier this week to find that Kenneth Anderson is a fellow early music fan! Not only that, but he also appreciates and plays the cello, my favorite non-percussion instrument. I listen to a lot of Baroque music, which of course means that I listen to a lot of J.S. Bach, especially the Brandenberg Concertos 1-3 and 4-6 performed by Trevor Pinnock and the English Concert, violinist Daniel Hope’s concertos recording, and Yo-Yo Ma’s cello suites recording. I’ve also had Ofra Harnoy’s recordings of Vivaldi cello concertos and Nigel Kennedy’s recording of Vivaldi’s Four Seasons in my short rotation for a long, long time. But other than the occasional Handel, that’s pretty much been the extent of my deep experience with Baroque music; I’ve long been a big Schubert fan, and have spent more time listening to classical and early romantic chamber music than digging into the Baroque and earlier periods.

For some reason, though, over the past year I’ve been fixated on Baroque and earlier music — completely and utterly fixated. About two years ago we saw Handel’s Giulio Cesare at the Lyric Opera, and it was just stunning musically and visually (it was the Glyndebourne production, available on DVD). And then late last winter I remember coming home from work one evening and walking in the door to find the KP Spouse listening to the Tallis Scholars performing William Byrd’s masses, and for some reason it bored into my brain. Thus two things converged for me — Baroque and earlier music, and my long-standing Anglophilic appreciation of sacred music, especially choral music performed by the Choir of King’s College, Cambridge (yes, I am that pathetic Anglophile who makes a point of listening to the Festival of Nine Lessons and Carols every Christmas Eve day!).

As a result I’ve been exploring more music and more composers — Pergolesi, Palestrina, Scarlatti, Purcell — and finding a wealth of interesting music! My favorites right now are two that I bought in London in August: a new recording of Purcell’s Fairy Queen and The Prophetess, and a 1994 recording of Bach’s The Art of Fugue. I also have a two-volume recording of Palestrina from the Choir of King’s College, Cambridge that I got recently that is rocking my world.

Anderson’s post at Volokh reminds me of more composers to check out, choral and string — Corelli, Gabrieli, Gabrielli (yes, there are two), Caldara, Sainte-Colombe — and I am grateful for that. Another great place to look for recordings of early music is Magnatune, an outstanding label that has lots of pre-1800 recordings (and reminds me to listen to Rameau and Couperin). Coincidentally, on Wednesday in the Telegraph, Ivan Hewett asks if Purcell was the best English composer:

In short, he knew his worth, and didn’t suffer fools gladly (another similarity with Mozart). His technical facility was astounding. In a guide to practical music published in 1697, Purcell described composing a set of variations over a repeating bass as “a very easie thing to do, and requires but little judgment”. It’s actually really hard, especially when combined – as Purcell often did – with strict counterpoint. His wonderful fantasias for viol consort are full of amazing feats, such as combining a tune with itself at three different speeds.

That doesn’t make him great, of course, but it means he had the necessary craft to capture his own expressive world, which was both enormously wide and sharply individual.

Thanks to Tyler Cowen for the link. I’ve never been much of a Vaughan Williams or an Elgar fan (although I have Yo-Yo Ma’s recording of Elgar’s cello concerto, which is quite nice), so I’m open to the argument for Purcell as one of England’s unjustly underappreciated composers.

We’re fortunate in Chicago to have a lot of early music resources, including the Early MusiChicago portal to hear about concerts, lectures, and so on. We have several performance groups/consorts, including the outstanding Music of the Baroque (which will be performing Mozart’s Requiem in February), the Newberry Consort, and the Chicago Early Music Consort. We will also be having the debut Chicago Early Music Festival this April.

For all of these reasons, 2010 looks like a great year for exploring early music! I will be doing so as mentioned above, and I’ll also finally take the plunge and get Glenn Gould’s recording of Bach’s Goldberg Variations. Do you have any recommendations to share?
