The design history of snowmobiles starts with propeller driven sleds, including the amazing Russian combat version and migrates to half track vehicles with rear engines. Today's front engine vehicles were pioneered by Polaris, and are represented here by the Arctic Cat F6 600, which is driven by Sarah Palin's husband. This list of personal snowmobiles also contains two state of the art concept single track motorcycle style vehicles by Keller and Schlootz.

The New York Times put together a fascinating list of Olympic flame relay torches. However, the cauldrons that they light are often more interesting being part of the original Athenian games, both figuratively and in spirit. The torch relay is neither, having been created by the Nazis.Dramatic sculptural cauldrons were built for more recent Winter or Summer Games, such as Salt Lake City, Barcelona or most recently, Turin, with its tall fire breathing chimneys, like an oil refinery burn off.Both Barcelona and Sydney introduced spectacle in the way the cauldrons were lit: a single shot, flaming arrow from a remote archer, in Barcelona, and a spectacular self assembling tower emerging, on fire, from a pool of water, in Sydney.The simple, iconic cauldron also stand out, and nowhere more so that the pared down minimalist version at the 1976 Montreal Games, which could not have been more different from the gargantuan vulgarity of the stadium itself.

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.

A gallery of products using radioactive materials.Because radiation was seen to be new and powerful, at the beginning of the 20th century radioactive material was used in products such as face creams, mineral water and medicine, by equating power with rejuvenation. For similar reasons it was even used in items from spark plugs to condoms. Although many of these items are from an age when the dangers of radiation were not known, radiation is obviously useful as a healing tool for cancer therapy, but it is still used in legal Chinese remedies, which are respected more because of their age rather than efficacy and quack homeopathic medicines which are tolerated while unproven, because they are harmless water.Vote on your fave examples.

Amazingly, the existence of the unsuccessful Soviet moon landing program was secret until the fall of the USSR. It consisted of three principal components: the N1 rocket; Soyuz 7K-L3 orbiter and LK lander.The first stage of the N1 is the most powerful rocket every built, it never launched successfully and when it blew up, it resulted in the largest non-nuclear, man-made explosion in history. All of the hardware looks similar enough to be familiar, but different enough to be slightly alien, such as the bug like lander, of which there are 5 left. All that remains of the N1 itself are a few scraps in a children's playground in Kazakhstan, but its engine type is still in existence, used by the company that formerly owned the satellite system used by Google Maps.

The Apollo 12 Quarantine Airstream – which ended up on a fish farm

July 15th, 2009 link to (permalink)

Vintage Airstreams are cool enough, but imagine owning a NASA moon astronaut quarantine version.

The Apollo 11 Quarantine trailer is in a museum and the never used Apollo 13 one is on board the USS Hornet, but the Apollo 12 one was sold off as surplus and ended up at a fish farm, as seen here.
An amazing find.
