Obvious the very word submarine implies something below sea level, so submarines on dry land are particularly weird. Here are some of our favorites, ranging from abandoned washed up submarines, like beached whales, to those which have been specially buried in the ground as museum exhibits.

Ever since James Bond had tricked out briefcases as an accoutrement for his array of gadgets, the idea of a suitcase full of a kit of gizmos for a specific task is seductive; or morbidly curious, in the case of apocryphal suitcase nukes.

Bridge layers have to be about the closest thing in the real world to a Transformer, giant fold up, extendable instantly deployable bridges that are most often fixed to modified tanks. They have been around since tanks first existed, during WW1, and are one of the more bizarre and obscure forms of military hardware. There is also something incredibly circular about a vehicle that carries its own road.

Before electricity, lighthouses relied on lamps that would almost be considered mood lighting by today's standards. Mechanisms were clockwork and had to be wound as often as every two hours. In the 19th century, Fresnel designed a lens that could focus this light into parallel rays and project it horizontally, dramatically improving lighthouses. By the end of the century, all lighthouses had Fresnel lenses classified into orders, with first order being the largest and most impressive.These days lighthouses use less elaborate lamps such as the beacons found at airfields, or even powerful, but unremarkable to look at, LEDs. Here is a list of some of the most beautiful and important lights ever made, including some 1st order beauties that stand 20 feet tall, and were floated on a mercury bed. There are no descriptions of each item, for this chart, as the images speak for themselves, however, the sites linked to have information about the lighthouses where they came from.

The Wienermobile is quintessentially American: pure, whimsical, 4-wheeled fun in the name of capitalism. It’s history goes rather like most design classics form Apple computers to the Coke bottle: 2 custom built homebrew prototypes (1936-40), a defining form (1958), a refinement of this to produce a classic, by a famous designer (1958, Brooks Stevens), variations on the same theme till now, with a novelty version in 2008.
