There were justifiable fears of being buried alive, before modern medicine could safely identify the difference between certain types of paralysis or coma and being dead. Fears which were exacerbated by fiction such as The Premature Burial by Edgar Allan Poe. As a result a bizarre range of contraptions were invented to signal having been buried alive, from bells, whistles and even a spring loaded ejector coffin which might actually kill other people from the shock of seeing an interred body spring out of the ground in a cemetery.Added to this were ranges of hermetically sealed iron coffins and a device to prevent grave robbing consisting of a booby-trap subterranean torpedo.For more of these, check out: http://deathreferencedesk.org/2010/02/02/premature-burial-device-patents/

And you thought the matrix was fiction? Robots designed to access hostile areas such as radioactive areas are also used beneath the streets to clean or repair sewers or to lay cables. They were among the first things on the scene after 911 or Katrina and have a particular rugged beauty. Vote for your faves.

Long before periscopes became uniquely associated with submarines, they were widely used to peer over the trenches in WW1. Here are other uses from on board jet aircraft to golf courses, bank vaults and even to look underwater from dry land - the inverse of what we associate periscopes with.

The irony in these advertisements for guns is sometimes accidental and sometimes deliberate. What many demonstrate, however, is that Americans' relationship to the gun is completely different from almost any other nation in history.

Flea circuses share one thing in common with combine harvesters. They are something that you hear about lot as a kid but rarely see. Popular since the 1600s till the late 19th Century, there is something fantastically creepy and Victorian about them, since they were cheap entertainment for the poor and the best performers were human fleas. Despite the mythology, flea circuses are real, and some still exist. Here are some pictures and videos to prove it.

This list covers the period from 1920 when the Harding - Cox election results were first broadcast by radio, to the present day when presenters have to interact with a virtual reality zoo of giant, artless, real-time animated charts.The first live TV election broadcasts were produced in the 50s, employing professional sign writers would have to paint charts, live. Static and very basic sets were used well into the 70s, as can be seen from the spartan US military set in South Vietnam for the 1972 Nixon election.Despite the technology behind contemporary broadcast sets, they are all unimaginatively dull, with identical patriotic, red white and blue color schemes and similar color blends and soft shading. These are the TV equivalent of a hideous blue-white blend default Powerpoint template.

Ironically, airports are one of the few things you often don't get to see an aerial view of since you don't get a cockpit seat. Here are a dozen of our favorites, purely in terms of their abstract graphical layout. See if you can guess them.

Kowloon Walled City (KWC) was a 10-16 storey monolithic 6.5 acre city block in the flight path of the old Hong Kong airport, that housed somewhere between 35,000 and 50,000 people when it was finally demolished in 1993. 30 times the density of Manhattan with no streets and little daylight, it was a rat infested, cockroach ridden filthy labyrinth. KWC was a no-man's land that fell neither under British Jurisdiction nor Chinese, where Hong Kong's appetites for the 3 vices: prostitution drugs and gambling could be satiated, but where ordinary families lived alongside nearly 800 factories and shops. It had 161 unregulated doctors and dentists along with food producers from whole pig roasters to the suppliers of most of Hong Kong's fish balls. Most of the people that lived in KWC never left.Dozens of sites have covered KWC before (as have we), but its such a strange and unusual Oobject that we've trawled through hundreds of sites to try a pull together a list of our favorite images and links which succinctly describe it.

It seems that for maximum impact, upside down houses need to be cartoon versions of what a building should be, pitched roof, symmetric, central door.

Jet engines undergo a variety of tests shown here, from chucking water, sand and flocks of dead birds into their gaping intakes. They are also tested to see what happens when a fan blade is destroyed while the turbine is spinning, with an explosive charge, not something to try at home. But the best tests of all are those involving jet engine afterburners and the best of the best has to be those with vector nozzles.These are real oobjects, objects that make you go ooh.

Quite often a company will release a limited edition item to mark a product's anniversary that is actually worse than the original. We trawled the web to find examples of well designed anniversary gadgets, including our favorite, the 300lb limited edition espresso machine that was used by the Pope. Vote on your favorite.

Although making a 3d image is more dramatic than increasing its resolution, say, the technology is fairly primitive. Because of this, stereo cameras are something of an interesting retro curiosity. These days, custom made stereo cameras with twin lenses at eye separation are usually replaced by custom rigs for digital cameras, with appropriate software.

ts very hot today, so we are giving you some visual ice cream - massive railroad snowplows. These devices which are both terrifyingly impressive, when in action (as the video in the list shows) and dramatically beautiful to look at either in the fan-like rotary versions or the futuristic wedge shaped models. Some of these plows are still being used, having been built in the 19th Century.

1927 to 1959 was the golden era of General Motors. This was the period when Harley Earl started as Vice President of the Art and Color Division and gave birth to the modern notion of car design.Earl eschewed the purely engineering driven practicality of Ford to take inspirations from aircraft and space age concepts and add them to cars, turning them into works of art. The designs ranged from the highly futuristic Firebird gas turbine concept vehicles to the wildly successful production Corvette.Like almost all product design and architecture, the stamp of authorship is not clear cut and nor should it be. Many designs that are associated with him were produced by people working under him, but it was Early himself who created the school and he deserves a place alongside Frank Lloyd Wright and Charles and Ray Eames as one of America's most important designers.Vote for your favorite.

Famous French industrial designer, Roger Tallon recently died, leaving something of a design mystery. Newspapers universally credited him as the designer of the iconic French high speed train, the TGV, but that was almost certainly the work of Jacques Cooper. Tallon did take over from Cooper to do the TGV Atlantique, but this was an evolutionary rather than a revolutionary design. Perhaps Tallon's influence was more on the interiors? For me, Tallon's best work was his 1960's M400 spiral stair which seems to be the direct inspiration for some of Ross Lovegrove's best work.

The Segway took the idea of the two wheeled vehicle and made it require thousands of dollars of electronics to remain as stable as an ordinary two wheeled bicycle. The Apple Newton was a personal organizer that required a personal assistant to carry it around for you.The common thread in the choices here is people mistaking sophisticated engineering for sophisticated design. Many were and still are technical triumphs.The Space Shuttle, for example, still bathes in the reflected glory of the Apollo missions, yet its design was largely a mistake based upon the PR potential of a plane-like craft, rather than practicality. Its replacement will look much more like a Saturn 5 rocket and it forms part of the hardware for what Nasa refer to internally as the ‘crude missions'.Below is our chart of the biggest all time tech. failures. Vote for the biggest loser or suggest some alternatives in the comments.

If you thought the Bullet train was the fastest thing on rails, you would be wrong - more than 6000 miles per hour wrong. Rocket sled test tracks were originally designed for the V2 in WWII and can reach up to 6400 mph.They were made famous in the 50s when Lt. Col John Paul volunteered himself to test a 200mph track designed for crash test dummies, called the Gee Whiz. The test was intended to show the effects of deceleration in a plane crash, where it was assumed that nobody could survive more than 18G. Strapp survived an unbelievable 35G.More recently a rocket sled was featured in Indiana Jones and the Kingdom of the Crystal Skull.However, the lasting legacy of the Gee Whiz test is Murphy's Law, coined after a real engineer called Murphy who worked briefly at Edwards Air Force Base on the test track.

Although current proposals for 4000 mph Maglev trains running in evacuated tubes, would offer New York to Beijing in less than 2 hours, built versions of pneumatic railways predate regular subways. Brunel built one, and an underground pneumatic railway was built by Alfred Ely Beach, in Manhattan, in 1869. The late 19th century stock market crash, depression and Civil War, destroyed the idea and little of it remains apart from the station, which features in the movie Ghost Busters II.

In case there were any doubt about just how unpleasantly weird Kim Jong Il’s tyrannical grip over North Korea, here are 12 examples of his propaganda posters. They range from imagery of attacks on the US in a bizarre blend of Soviet art and 50s American comic books to perhaps the most macabre of all, pictures of copious abundance of produce in a place where people are starving to death.
