Early designs of perpetual motion machines were done by Indian mathematician–astronomer Bhaskara II, who described a wheel (Bhāskara's wheel) that he claimed would run forever. [ 2 ] A drawing of a perpetual motion machine appeared in the sketchbook of Villard de Honnecourt , a 13th-century French master mason and architect.
A lottery machine is the machine used to draw the winning numbers for a lottery. Early lotteries were done by drawing numbers, or winning tickets, from a container. In the UK, numbers of winning Premium Bonds (which were not strictly a lottery, but very similar in approach) were generated by an electronic machine called ERNIE.

The rival machine, the throstle frame or ring frame was a continuous process, where the roving was drawn twisted and wrapped in one action. The spinning mule became self-acting (automatic) in 1830s. The mule was the most common spinning machine from 1790 until about 1900, but was still used for fine yarns until the 1960s.
The wheel consisted of curved or tilted spokes partially filled with mercury. [1] Once in motion, the mercury would flow from one side of the spoke to another, thus forcing the wheel to continue motion, in constant dynamic equilibrium. Like all perpetual-motion machines, Bhaskara's wheel is a long-discredited mechanism.
An electrostatic pinwheel, or corona spinner, attached to a small Wimshurst machine (electrostatic generator) is shown stationary and rotating. Ion wind, ionic wind, corona wind or electric wind is the airflow of charged particles induced by electrostatic forces linked to corona discharge arising at the tips of some sharp conductors (such as points or blades) subjected to high voltage relative ...
That wheel then spins another bladed wheel, sucking and compressing outside air into the engine. Superchargers - Superchargers are used for engine-power enhancement as well, but only work off the principle of compression. They use the mechanical power from the engine to spin a screw or vane, some way to suck in and compress the air into the engine.
In 1757 the Rev. John Dyer of Northampton recognised the importance of the Paul and Wyatt cotton spinning machine in his poem The Fleece (Dyer, p. 99): A circular machine, of new design In conic shape: it draws and spins a thread Without the tedious toil of needless hands. A wheel invisible, beneath the floor, To ev'ry member of th' harmonius ...
