Cutaway drawings are a standard way of revealing the inner complexity of machines, and they are an art form unto themselves. Occasionally cutaways are real, however, as with this collection of cars which have been literally sliced apart to show their innards.

Sometime in the last few years bored programmers realized that they could strap things like chairs and surfboards to the end of an assembly line robot – and so was born the robocoaster. Here are some videos of them as actual rides and as a recreational high for coders.

Inflatables are an obvious choice for space vehicles and satellites, a small sized payload than can be inflated once up, yet for some reason they aren't the norm.The first passive communications satellites were inflatable spheres, such as the Echo series, which mylar was developed for, and early prototypes for space stations were inflatable. More recently, funding for the inflatable replacement for the habitat unit on the space station was cancelled and a private company Bigelow Aerospace is now the pioneer in the field, having successfully launched an inflatable unit.My favorite in this list, however, is the grid sphere satellite which replaced the Echo ones which didn't stay up long becuase the suns heat would deform them and slow them down. A helium inflated plastic balloon expanded a signal reflecting hollow geodesic mesh, with the plastic then dissolving under the suns rays. The mesh could then stay up for 11 years or so.

Phoropters, the gadgets used by opthalmologists to test your eyes look like the most spectacular binoculars you have ever seen.The traditional complex mechanical versions are technological works of art made by lens makers such as Bausch and Lomb and have the design quality of a classic vintage Leica camera. Only now are these marvelous gadgets slowly being replaced by simpler looking, wireless, digital versions which relay data to a computer for image analysis.

This year is special, in theory it is the first year since 1982 that keytars have not been mass produced as musical instruments, and that would have been something to celebrate if Guitar Hero and Rock Band hadn't brought them back, with a vengeance in the form of game guitars.This list is a warning reminder of what people really look like when they play Rock Band. It features keytars from their earnest debut to parody, to some kind of post-post-modern resolution with self aware but not-really-joking keytarists like Ben Folds.After the Moog Liberation was introduced in 1980, a variety of performers from Thomas Dolby to Jan Hammer made keytars a staple of 80s music, with Devo being the first to seize the ironic potential. Later weird Croation keytarist Belinda Benekovic became an internet meme and more recently Flight of the Conchords took a jab at a Roland Axis player.Her are some videos of keytars in action from classic 80s synths to circuit bent toys. Vote for your worst.

Manikins (the alternate spelling, mannequin, is usually used for the store window variety) which are used for medical training are extremely interesting devices with accurate and working anatomical elements. This list is larger than usual since the number of interesting items meant that we kept on looking.

Suits for hazardous materials are serious business and high tech., but look ridiculous. They come in several varieties: Splash Suit, Gas Suit, Turnout Coat for different levels of contamination. Their look ranges from giant pink translucent condom like outfits, to oversize Tasmanian Devil shaped suits. From the examples in this list, standard training procedures include washing down while standing in a regular inflatable kids paddling pool and basketball dribbling.

Last night our very, very ,very bad cat had diarrhea, then stepped in it, walked all around the house and trampled all over the bed. Here is a list of the best gadgets to deal with cat and dog feces, including a $7000 device for cleaning out paddocks, which I think we might have to buy.

Although the West Coast of the US and Japan have plenty of above-ground, tangled, utility cables, for some unknown reason telephone and electricity cabling in Vietnam is particularly horrendous. This list, may seem like an obscure joke until you look at the examples of some of the worlds most unbelievable rats nests of above ground cabling - all in Vietnamese cities.

Anyone self respecting geek who has been spellbound by the inspired rescue of the Chilean miners, will have found plenty of great info-graphics showing just how impressive a mine is. Here we have gathered some other cutaways, sections and 3d models showing a variety of mines, from the two coal mine alternatives (room and pillar or longwall) to the cavernous chambers of salt mines. Most impressive of all, however, is the physical model of Kidd Creek mine in Ontario where the relatively insignificant looking blobs at the bottom are the world's tallest man made structures, to scale.

Although the term galvanometer is often used to refer to things other than devices which measure electrical current (such as charge or resistance), there are an amazing array of early designs for this instrument, considering their simplicity.Many of these design differences are to do with the cases that surround what is basically a twisting wire, however there is something definitively analog in their mechanism and 19th century amateur scientist in their variety. Early galvanometers represent the extreme opposite of todays high energy physics, which requires giant multi billion dollar apparatuses and extreme digital processing for measurement. A long way off a compass and a battery.

New York's retro futurism is particularly interesting becuase the city itself is an anachronistic view of modernism - an antique skyscraper city. Each one of these proposals is not just a past vision of the future, but a past vision of the future which is now in the past itself.The 15 items here, range from the purely conceptual work of Italian 60s architects, Superstudio, who designed a continuous monument around the earth, crashing through lower Manhattan to Lindenthal's serious proposal for an absolutely gargantuan bridge across the Hudson, with towers bigger than some of the tallest skyscrapers and where the keystone, still exists today.Along with Buckminster Fuller's well known idea for a geodesic dome over mid-town Manhattan, is his lesser known one for an array of huge, cooling tower like housing projects in Harlem, each holding 40,000 people. There are a couple of representative engineering projects showing plans to dam the Hudson or drain the East River and an array of transportation concepts, including Raymond Loewy's idea for a helicopter pad covering Bryant park, 10 storys above ground.Weirdest of all is the proposal for a spherical nuke proof 2nd city, below ground.

Airstream was neither the first nor the only manufacturer of streamlined trailers with examples shown here, by Spartan, Silver Streak, Westcraft and Bowlus, among others, yet they are deservedly the best known and continue to thrive. Because of their futuristic design they have a unique place in the history of technology. An Airstream was used for quarantine after the first men returned from the moon and today takes astronauts to the Space Shuttle. Their iconic silver bullet shape still looks modern, yet it dates from the 30s and is based upon a prior streamline designed trailer, called the Bowlus. Here is a list of some of the most beautiful things to have ever been on the roads.

Charles Sheelers iconic image of the Albert Kahns Ford River Rouge Plant, with its criss crossing conveyors and spire like chimneys, is probably the most iconic image of the American Car manufacturing industry whose future, like Kahns original buildings, hangs in the balanceEven among architects, Albert Kahn is less renowned than Louis. But Albert Kahn is far more important in terms of the influence of his buildings. He is sometimes referred to as the architect of Detroit. Kahn invented the American factory style, taking early European modernism to the place where assembly lines were invented and developing an architectural style that was supremely innovative both in terms of construction and design. The plants he built are in many places around America, but most famously in Detroit, where, lie the car industry itself, some of his most important building lie in ruins.We have two favorite images in this list. One if of the abandoned Detroit Public Schools Book depository, with its once minimalist, clean modernism in absolute and total decay, overflowing with rotting books strewn across its floor. The other image is, of course, Charles Sheelers

There’s not much information about helter skelters on Wikipedia, so we decided to find out more:Despite becoming a recent fixture at Victorian themed winter fairs and a perennial one at summer funfairs, the helter skelter is clearly modeled on a Victorian lighthouse, and so is originally and end of pier attraction. We found a picture from 1907 where the helter skelter is clearly labeled as a one and we even found one labeled a helter skelter at Coney Island, so perhaps its a term that did carry to the US. The architectural style is even referenced in a spire at Disneyland, the capital of the funfair world.An almost exclusively British term for a spiral fairground slide, helter skelter is known in the US from songs by the Beatles, Oasis and Genesis, and from the association with Charles Manson. In the UK its one of those things that every child can recognize, but which when you really look at, becomes strangely unfamiliar and weird – an architectural naked lunch. The taste of this naked lunch combines hints of jousting, medieval pageants and overtones of Paganesque Englishness, from Morris Dancing to the Wicker Man. Its principal flavor, however, is of the English seaside: damp and Victorian.

Babel is interesting because it represents the ultimate in imaginary architecture, a skyscraper of the mind. The Tower of Babel is the archetypal image of a giant tower, a man made hill, yet nothing like our idea of it has ever been built. The closest are possibly Mont Saint-Michel or perhaps the downtown Manhattan cluster, yet one is a natural mound and the other an apparent hill created from many buildings.The idea of Babel traces back to ancient Sumerian stories from the time of 5000 year old Mesopotamian Ziggurats, to the reinterpretation of these myths in the book of Genesis. In the 16th century the ironic obsession with Babel among 16th century painters in hill-less Lowland Europe, created the most well known imagery, but it evolved further with the unbuilt Palace of the Soviets or the imaginary babel in the retro futuristic skyscraper cities of Fritz Lang's Metropolis.

Metal plate armor is one of the few technologies that emerged, disappeared in the 18th Century then re-emerged briefly during World War 1. Because of the this, WW1 armor has a particularly creepy, anachronistic look, from chain mail fringed splatter masks to body armor which looks decidedly Roman.

One of Silicon Valleys most famous landmarks, and possibly its only truly monumental one is under threat of demolition. The giant airship Hangar One at NASAs Moffett Field, is one of Americas architectural treasures.Airship hangars were collectively the largest spaces ever built, larger than cathedrals and just as awe inspiring. Vote for 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.

Imagine a gas powered desktop publishing system that weighed several tons, leaked oil, had thousands of moving parts, its own boiler full of molten lead and a keyboard where you couldn’t see what you had typed and which looked a thousand times more strange and complicated than any deliberately anachronistic Steampunk PC casemod.

This is how the machines that laid out the pages of newspapers were till the 80s, and to give some idea of how recent this technology was used, they were manufactured until after the release of the Apple computer. Linotype had a virtual monopoly on the typesetting of newspapers for a hundred years and their design is a superb example of an endlessly refined solution to what became an anachronistic problem. Linotypes were unlike any keyboard driven device, before or since.


Machines designed to smash large tough items into small bits, including a machine that eats trees whole, and yes, a real bone crusher, that makes fertilizer from animal bones.

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.

Resqtec make instruments that prise open cars after a crash or find people in the rubble of buildings after an earthquake. What's amazing about this equipment, however, is quite how beautifully designed it is.
