Tree Windmill (1901)
December 6, 2010 by Filed Under: Random, Trees, Wind Power, Windmills
Last year, William Kamkwamba made headlines around the world with his crude windmills built out of tree trunks and scavenged materials.
He could have saved himself some work if he had seen the illustration on the right, which I copied from a 1901 Dutch newspaper. The accompanying text says:
“Windmills are ugly contraptions and many attempts have been made to make them look better. This illustration shows how nature and mechanics can coexist.”
“It is a windmill constructed in combination with two trees. The trees only serve as a support for the upper part and for the ladder to reach the top. The mill was built in Illinois (US) and worked so well that several have been constructed.”
I could not find any more information about it.
Primitive Kitchen Timer by Ludvik Cjep
“This wooden chronograph works according to the principle of a kitchen timer. An interval from 0 to 60 minutes can be set on the yellow clock face. When the time elapsed a tinkling signal sets off at the Bottle on the upper right side of the timer. The forefinger of the blue hand under which the yellow clock face is gliding, indicates the time set, resp. the time left. At zero the finger falls into the notch at the circumference of the clock face. Hereby the whole arm is lowered and the blockage of the ringing mechanism is lifted.”

Metropolis II by Chris Burden
“The California artist Chris Burden may be in his 60s, but he is still playing with toys. The thing is, the older he gets the more outrageously complicated the toys become. ‘Metropolis II’ includes 1,200 custom-designed cars and 18 lanes.”

Horse-Drawn Public Transportation

“For a hundred years, from the early 1800s to the early 1900s, Europe and America had cities of at least a million people that ran on a massive, sophisticated network of carriages and streetcars. By 1880, according to historian John H. White, Jr., US cities had 415 horse-drawn railways running, with 18,000 cars on 3,000 miles of track, carrying 1.2 billion passengers a year. Most of these lines continued decades into the age of electricity and coal, simply because the horses worked better than any other option.” Read: Horse-drawn public tranportation. Thanks, Johan.
