Superconductivity and the [near] future




Superconductivity is one of those things, like fusion energy or quantum computing, that are always JUST ABOUT TO make a big splash in the world, change everything ... and ten years ago this was just on the verge of happening too, and in another ten it will still be right on the knife's edge of realization. And so on.

The notion that superconductivity will be the next big thing comes from experience of materials at very low temperature, Properly cooled materials (most often metals such as lead, tin or aluminum) conduct direct current (DC) electricity without energy loss: resistance vanishes. 

If you've watched cheesy old sci-fi movies in which aliens tell humans "resistance is futile" you will probably be at work on your puns already. Still ... the absence of current resistance is enticing. It is a prospect with no end of possible practical applications.

But, of course, the process of cooling the proposed superconducting material below the threshold temperature and keeping it there is not costless. Indeed, the danger is that any serious attempt to implement this will involve the expenditure of more energy of the cooling than is then saved on the resistance-free transmission.

The latest company to claim that it has solved this problem and is about to unleash superconducting upon the world in a big way is VEIR, a firm based in Woburn, Massachusetts. It aspires to change the US power grid. Here is a link to the website. 

Are they going to pull this off?  You heard it from me first, psssst, probably not.

A Story About Coleridge

This is a quote from a memoir by Dorothy Wordsworth, reflecting on a trip she took with two famous poets, her brother, William Wordsworth, and their similarly gifted companion, Samuel Taylor Coleridge.   We sat upon a bench, placed for the sake of one of these views, whence we looked down upon the waterfall, and over the open country ... A lady and gentleman, more expeditious tourists than ourselves, came to the spot; they left us at the seat, and we found them again at another station above the Falls. Coleridge, who is always good-natured enough to enter into conversation with anybody whom he meets in his way, began to talk with the gentleman, who observed that it was a majestic waterfall. Coleridge was delighted with the accuracy of the epithet, particularly as he had been settling in his own mind the precise meaning of the words grand, majestic, sublime, etc., and had discussed the subject with William at some length the day before. “Yes, sir,” says Coleridge, “it is a maj...

Searle: The Chinese Room

John Searle has become the object of accusations of improper conduct. These accusations even have some people in the world of academic philosophy saying that instructors in that world should try to avoid teaching Searle's views. That is an odd contention, and has given rise to heated exchanges in certain corners of the blogosphere.  At Leiter Reports, I encountered a comment from someone describing himself as "grad student drop out." GSDO said: " This is a side question (and not at all an attempt to answer the question BL posed): How important is John Searle's work? Are people still working on speech act theory or is that just another dead end in the history of 20th century philosophy? My impression is that his reputation is somewhat inflated from all of his speaking engagements and NYRoB reviews. The Chinese room argument is a classic, but is there much more to his work than that?" I took it upon myself to answer that on LR. But here I'll tak...

Recent Controversies Involving Nassim Taleb, Part I

I've written about Nassim Taleb on earlier occasions in this blog. I'll let you do the search yourself, dear reader, for the full background. The short answer to the question "who is Taleb?" is this: he is a 57 year old man born in Lebanon, educated in France, who has been both a hedge fund manager and a derivatives trader. He retired from active participation from the financial world sometime between 2004 and 2006, and has been a full-time writer and provocateur ever since. Taleb's writings for the general public began where one might expect -- in the field where he had made his money -- and he explained certain financial issues to a broad audiences in a very dramatic non-technical way. Since then, he has widened has fields of study, writing about just about everything, applying the intellectual tools he honed in that earlier work. As you might have gather from the above, I respect Taleb, though I have sometimes been critical of him when my own writing ab...
