Vehicles that are actually driven by screws were developed as all terrain vehicles for places like snow driven Siberia. In the US there were several experimental vehicles including the Fordson snow devil, built on top of a tractor. Included here are as many videos of them in action, as I could find.

Although the Omega Speedmaster is the most famous space watch, being worn on all moon missions, it is one of 7 watches which are NASA certified, including a range of far less glamorous Casio G-Shocks. Ironically, the watch which has possibly been in space most is one that costs a fraction of the price of a Speedmaster and is more associated with computer geeks - the Timex Datalink.Rules as to what watches could be worn by Russian Cosmonauts were more relaxed, however, Poljot military watches were often worn. The Chinese have chosen the Fiyta Chronograph for their manned space missions.

watches worn in space have just released their updated list of the worlds most powerful supercomputers. In June all of the top 5 were in the US, now only 2 are, with India, Sweden and Germany appearing.Here's an interesting thing, you can make it into this list for less than the cost of a family house in Manhattan.The fact that a Swedish Military computer is at number 5 indicates that either the Swedish military require the world's most powerful computers, or they are just unusually unsecretive, and that there are many machines we don't know about.Here are the top 15, with pictures of the actual machines, where they have been built. Although the IBM Blue Gene has a simple and striking case, only the Barcelona Computer Center and Leibniz Rechenzentrum are contained in rooms that are at all impressive. Vote for which ones you think are worthy of note.

Although we previously did a list on diving helmets, the variety of strange diving outfits warranted another list. Having spent hours pouring through these to pick my favorites, it occurred to me that the inspiration for early science fiction robots and space suits, before the age of actual space travel, clearly comes from this pre-space age technology.Deep sea diving equipment needs to be solid and heavy it has a very different aesthetic from aviation and space equipment which needs to be light, so there is a market difference between the look of space things in science fiction, between the 50s and 60s.

Jean Nouvel created a spectacular facade, based upon electronically controlled camera iris shaped devices in the style of decorative Arab screens, for the IMA in Paris, 20 years ago. For some reason, mechanical facades have recently started cropping up here and there in architecture. Here are some of our favorites.

12 Creative Uses of a GoPro

April 23rd, 2012 link to (permalink)

Aside from the POV Parkour here, non of these videos involve super human skills, Spidey Senses or Red Bull addiction. I actually prefer the seemingly bland but interesting ones such as strapping a GoPro to a dog, hula hoop, time lapse of the view out of a commercial flight or RC car in Walmart to endless surfing videos
