Clock That Needs No Winding.

Two Austrian watchmakers have built a clock which receives its motive power from a current of air blowing upon a turbine-shaped wheel. The clock is so simply built that the current of air produced by a stove or kitchen range 1b sufficient to make it go. The air is brought to the clock by a pipe fixed upon the wall. A very strong current is reduced by a certain clever contrivance which regulates the speed of the works.
