If it woes, it leads

We’re backing into the climate future/present with woes leading the way. It’s the perfect media framing and supports the status quo – yes everything is awful. We’ve tried nothing and we’re all out of ideas, let’s see how we can keep cheap gas going a little bit longer. It’s this way, in part, because ALL of the progress is boring. For instance, wide bandgap:

Silicon and silicon carbide are useful in electronics because they are semiconductors: They can switch between being electrical conductors, as metals are, and insulators, as most plastics are. This ability makes semiconductors the key materials in transistors — the fundamental building blocks of modern electronics.

Silicon carbide differs from silicon in that it has a wide bandgap, meaning that it requires more energy to switch between the two states. Wide bandgap, or WBG, semiconductors are advantageous in power electronics because they can move more power more efficiently.

Silicon carbide is the senior citizen of WBGs, having been under development as a transistor material for decades. In that time, engineers have started using younger upstart WBG materials, like gallium nitride, or GaN. In the 1980s, researchers used gallium nitride to create the world’s first bright blue LEDs. Blue light comprises high-energy photons; gallium nitride, with its wide bandgap, was the first semiconductor that could practically produce photons with the sufficient energy. In 2014, three scientists were awarded the Nobel Prize in Physics for that innovation, which became ubiquitous in devices like TV screens and light bulbs.

Lately, researchers have started using gallium nitride to improve power electronics. The material reached commercial fruition over the past few years in adapters for charging phones and computers. These adapters are smaller, lighter, faster-charging and more efficient than traditional ones that use silicon transistors.

“A typical charger that you buy for your computer is 90 percent efficient,” said Jim Witham, chief executive of GaN Systems, a Canadian company that supplied the transistors in Apple’s gallium-nitride laptop chargers, which were released last fall. “Gallium nitride is 98 percent efficient. You can cut power losses by four times.”

Keep going, science.

Math Lesson v. Popular Garbage

Now, popular garbage can and does take all kinds of forms. In this case, it’s Superfreakonomics, the swftly-selling follow-up to Levitt and Dubner’s Freakonomics. A counter-intuitive take on economics? Whoa, count me in!

Panned in all the finest establishments, not least (and maybe the best) by Elizabeth Kolbert in the current New Yorker, the new book has all of the appeal of high-minded contrarianism for the too smart to think mixed with the feel good ease of shortcuts to to problematic solutions. Consider the promise of certain geoengineering solutions to the AGW set (The denierati, in common parlance). Anyway, Kolbert slices, dices and disposes, but also gives the nod to one of Levitt’s colleagues at the University of Chicago, Raymond Pierrehumbert.

In an open letter published to RealClimate, Dr. P-h brings it:

By now there have been many detailed dissections of everything that is wrong with the treatment of climate in Superfreakonomics , but what has been lost amidst all that extensive discussion is how really simple it would have been to get this stuff right. The problem wasn’t necessarily that you talked to the wrong experts or talked to too few of them. The problem was that you failed to do the most elementary thinking needed to see if what they were saying (or what you thought they were saying) in fact made any sense. If you were stupid, it wouldn’t be so bad to have messed up such elementary reasoning, but I don’t by any means think you are stupid. That makes the failure to do the thinking all the more disappointing. I will take Nathan Myhrvold’s claim about solar cells, which you quoted prominently in your book, as an example.

He then goes on to quote-unquote do the math, to show that Levitt and Dubner’s refutation of solar energy capture solely on the basis of the waste it generates is yet another example of making us play a game of ‘fool or liar’, in which he respectfully eliminating the possibility they are fools. He even shows his work, by manner of screenshots of wikipedia searches and other applications of The Google.

So, to recap… the tally after 4 innings

Math lesson: 1,  PG: infinity- 1

But PG is definitely on the run.
