Britain is probably the only country in the world where electric vehicle use is declining, due to the rapid disappearance of the electric milk delivery vehicle, or milk float.Until recently it was common place for milk to be delivered to almost every house in the UK, daily. Presumably in order to secure the national flow of tea. To achieve this a vast army of distinctive, cheap looking, sluggish, electric utility vehicles paraded suburban streets.Here are some different varieties, including new concept vehicles and milk floats from movies, all preserved for posterity.

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.

The picture of people hunched over radar screens is the ultimate image of the cold war. Here are a collection of various radar consoles, from land air and sea and from round analog displays with orange, green or blood red displays, to today’s computer monitor versions.

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.

Bamboo scaffolding is used around the world, but nowhere does it stand out more than in Hong Kong, where the majority of scaffolding is bamboo. It may look low tech. but bamboo is a perfect scaffold material, being strong, straight, lightweight, cheap and renewable. This ancient building material is most impressive when juxtaposed against modern high tech buildings and is sometimes used as scaffold for the tallest of skyscrapers. Here is a list of our favorite examples.

Although this list has been done by others, we have spent an unhealthy amount of time looking for specific examples of massively long, futuristic tunnels and impressive stations to give a definitive list from specific vanatage points, including some more obscure examples.

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.

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

July 15th, 2009 #link

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.
