WTC Attacks Not Listed On Bin Laden’s FBI Poster

Today’s Washington Post notices today what I noticed last week: Osama Bin Laden isn’t wanted by the FBI for the attacks of 9/11. Nowhere on his most wanted poster does it mention the September 11, 2001 attacks on the Pentagon or the World Trade Center.

The article says its because Bin Laden’s never been charged with the attacks. In a way I’m glad to see the FBI is going by the book on this one, and only listing crimes for which a suspect has been indicted.

Rule of law. What an amazing concept. If only the rest of the gummint held this standard.

Cheap Thoughts: Air Conditioning

I’m listening now as the air conditioner in my office slowly tears itself apart. Bad bearings have once again caused it to wheeze as it runs, providing some grating background noise as I work. Left unaddressed for a few days, it will increase to a point where one cannot think.

The air conditioner is a fussy, mechanical affair, largely unchanged since its invention in 1842. That’s when Dr. John Corrie of Apalachicola, Florida thought to use a compressor to cool his hospital patients. A compressor is still at the heart of today’s air conditioners.

Still, in a hundred and sixty years compressors haven’t evolved much. Like the one squealing over my head right now, they need frequent maintenance, they’re very sensitive to voltage changes, and they consume a tremendous amount of electricity. Why, after 160 years of cooling air, do we still use such a troublesome part?

Why do places like California and New York suffer blackouts in the heat of summer? They do because of electricity demand fueled by air conditioner compressors. People don’t turn on more lights or run more equipment when it gets hot. That surge in electricity demand is all air conditioning.

There are ways of cooling things which do not require a compressor. A recent technology called thermoacoustics uses sound to do the work. While thermoacoustic refrigerators are still under development, they promise to solve many of the issues plaguing modern air conditioning. Should they catch on, air conditioners will become more reliable, perhaps even more quiet, and use a fraction of the electricity the compressor models use. Our need for oil, coal, and neutrons to cool ourselves will drop as well. It will be nothing short of revolutionary.

With every whine and grind of the compressor above me, I long more for this cooling revolution.
