At first glance this lesser known part of the telephone inventor's life seems crazy. Bell became obsessed with pyramids, building towers, buildings, boats, kites and eventually planes made entirely out of little tetrahedrons (triangular pyramids). Eventually setting up the Aerial Experiment Association, he built 3 tetrahedral kite planes where each pyramid frame component had 2 of its 4 sides covered in fabric.His obsession, however, was ingenious and is possibly feasible - that if you could fly a pyramid frame structure then by combining lots of them together you would be adding no more weight per unit of lift, so you could fly a structure of any size.Although only one of Bell's planes managed to fly under its own power, the tetrahedral frame structure was to become a much used component of high tech architecture more than half a century later, giving these images of the Victorian inventors a bizarre science fiction feel.

Unintentional comedy is one of the consequences of Moores Law (that computer power doubles every two years) and almost any claim made in a computer ad more than a decade old. Included here are claims that compared to the Macbook Air that I am writing this on, a computer with 2 million times less RAM will "satisfy your lust for power"; that a computer a thousand times slower will give you "answers fast" for demanding applications and that a computer with several thousand times the volume is "compact and mobile".

Long before periscopes became uniquely associated with submarines, they were widely used to peer over the trenches in WW1. Here are other uses from on board jet aircraft to golf courses, bank vaults and even to look underwater from dry land - the inverse of what we associate periscopes with.

9 nail houses

December 21st, 2012 link to (permalink)

Nail houses have become emblematic of the accelerated rate of development in China. They are buildings whose owners have resisted selling to developers and which remain standing in the middle of new construction all around, like stubborn nails which can't be beaten down with a hammer. Here are 9 examples including ones in the US and Europe.
