Heart rate monitors connected to an ink plotted graph are a staple of movies and TV and they usually come in beautiful portable versions by companies such as Lafayette Systems, making them a classic spy suitcase gadget.Polygraph lie detectors are widely believed to be useless quackery, no more effective than a Scientology Dianetics machine, but they are commonly used by law enforcement and government agencies, usually in the US and are an anachronistic cultural legacy of the cold war.Today, the classic analog polygraph is being replaced by much less interesting computer versions.

I started this list as a Thanksgiving homage to American innovation via its greatest inventor. Reading more about Edison and his strange obsession with things like filming electrocutions, using alternating current, of everything from small animals to people and even an elephant, just to try and put people off the rival AC system, managed to put me off him. So as an act of revenge here are some of his less successful, stranger inventions from concrete phonographs to what became the tattoo machine and a ghost detection instrument. Happy Thanksgiving anyway.

I combined two types of concept plan in this list that are very different but share the fact that they show an alternate universe where airports weren’t giant fields on the edge of cities.On the one had there are the airports that literally float on water, and although these have become a reality with projects such as Kansai or military aircraft carriers, some of the original designs are for runways floating on rivers right in the middle of cities. Here the concept overlaps with the other type of floating airports: those that metaphorically float above the city on stilts – or over rather than on a river, via a structure like an overhead railroad.These concepts are not as unpractical as they appear, by using short-takeoff, quiet planes, London city airport is very close to the financial center of London and its a shame that aircraft haven’t been developed to allow some of these magnificent, early ambitions to have become a reality.

The original British Secret Service headquarters was just that, secret. But the increase in importance of electronics meant that it was more important for a building to be invisible to electronic eavesdropping. as such the current M16 HQ in London is about as obvious a giant sign saying ‘secret building here’, yet it is enclosed in a giant Faraday cage to protect its communications.Not all Intelligence agencies have had a discrete architectural past, Franco’s House of Screams, or the Soviet Lubyanka are demonstrably terrifying. Mossad’s HQ, until the 60s or the current Australian Secret Intelligence Service look quite modest compared to the hardly known Ministry of National Security of Azerbaijan, which houses its intelligence service, in a large and monolithic building of dramatic proportions.

The original wireless network used pigeons. One of the worlds largest information firms, Reuters actually started out as a messaging service with carrier pigeons, they were used widely for messaging during the WW1 and even for aerial photography. The famous psychologist, Skinner worked on a guided missile which was to be controlled by live pigeons.

If imitation is the sincerest form of flattery then Apple is getting it in spades.For those that worry about Apple blazing a trail for others to copy less expensively, its not that simple. A product like the iPhone is heavily tooled rather than fabricated. The hole for the headphones is actually drilled. To do this, Apple have hogged the world’s supply of the type of high tech, multi-dimensional machine tool needed.While companies like Nokia may copy, they may not be able to get the same build quality, even if they want to. Vote on the most blatant copy and post tips in the comments.

A perfect environmental nightmare, these hellish looking open faced mining machines have been largely decommissioned. Luckily some are being preserved as they are staggeringly impressive. The Ferropolis in Germany has many of these machines on display and forms an industrial park which host the famous MELT music festival. There have been several images of these floating around blogs, including the infamous pictures of the bucket wheel excavator that swallowed a full sized bulldozer, however we have tried to find as large a variety as possible.

12 tourbillon watches

February 21st, 2013 #link

Tourbillon watches are the most expensive in the world often costing $500,000. They became fashionable in the last decade as non-forgeable status symbols for billionaires, but that is now being threatened by Chinese imitations.The style of these devices is baroque in the truest sense, but becuase their aesthetic derives from the rational world of mechanics the style jars and they are, to my mind, as grotesque and kitsch as their diamond encrusted counterparts in the luxury watch market.After facing the existential threat of digital which made accuracy cheap, the Swiss watch industry turned to making high end jewelry either directly with diamond encrusted gold watches or indirectly via those that fetishised complex mechanics for the sake of it, such as these. Ironic, since the origins of Swiss watch making came from the ban on jewelry in Calvanist Geneva.These tourbillon (whirlwind) watches are the most extreme example of complex analog mechanics, the most expensive clockwork items in the world, costing between $100,000 and $500,000, they all share a rotating escapement which theoretically leads to better accuracy (even though that does not compare to a $50 swatch).This mechanism is very difficult to make and fascinating to look at, so most tourbillon watches directly expose their intricate mechanics, which originally only the Swiss could make. Recently, however, Chinese watch makers have brought tourbillon watches to market, for a tenth of the price, threatening their cache as a status symbol which is difficult to fake.
