The Hase Klimax has won the Eurobike 2010 award. The Klimax is a recumbent trike with a foldable fairing and electric assist. Beats any electric city car in terms of efficiency.
Pterosail Trike Systems is sailing and cycling over 3,000 miles from coast to coast across the USA this summer. The Pterosail is a street-legal recumbent tricycle with sails. It can reach up to 40 mph in good winds. No wind? Pedal. See also, below: the Whike, a Dutch made sail assisted trike.
I wrote about prison treadmills before. They were invented in England in 1817 by Sir William Cubit, who observed prisoners lying around in idleness and put himself to the task of “reforming offenders by teaching them habits of industry”.
Forty-four prisons in England adopted it as a form of hard labour that could also grind grain or pump water.
However, as it turns out, in at least one jail prisoners were only “grinding the wind”: they were walking a treadwheel that was connected to a giant fan built on the courtyard. By this apparatus the resistance necessary for rendering the tread-wheel hard labour was obtained.
The system is explained in “The criminal prisons of London and scenes of Prison Life” (1862), written by Henry Mayhew & John Binny. Starting on page 299, they describe the method of “hard labour”, and the technologies used for it: the treadwheel, crank labour & the shot drill. Great reading.

The punitive treadmill was then implemented in America for two long years, between 1822 and 1824, at Bellevue penitentiary outside New York. Prisoners stepped on the mill for 10 hours a day (with 20 minute breaks per hour), grinding grain, often with a large audience of jeering onlookers housed in a specially built viewing house.

Maybe artists and fantasy are a better foothold for the future than engineers and high-tech. The pedal powered Hennepin Crawler is capable of both street and railroad track cruising and can seat four people. It is comprised of approximately 90% recycled materials and has a sex appeal that can rival that of a Porsche or a Land Rover. Via Make 17. Related: Cycle Chics. More on railcars. More low-tech cars.
