The first mechanical cooling system was invented by Dr. John Gorrie. -Qwasas
Air conditioning techniques were used in Ancient Egypt, Ancient Rome, and medieval Persia. Mechanical cooling has been around since the 2nd century.The first modern electrical air conditioning unit was invented in 1902 by Willis Carrier.Air conditioning was invented in 1783
The first cooling fan was invented in 1882. It was invented by Schuyler Skaats Wheeler. The ceiling fan was invented in 1887 by Philip Diehl.
Herman Hollerith who developed the first mechanical tabulating system in 1890 (approximately).
The idea of artificial people dates back to time immorial;certainly to 1000BC. However, the first mechanical automata we're made in the 18th century as sophisticated mechanical toys. In 1926, the first "modern" robot was built by Westinghouse - it was the first robot that could do useful work.
Archimedes of Syracuse invented the water screw, and Sir Joseph Whitworth invented the first standard screw thread system.
who invented the first mechanical digital calculator
The first computer cooling device was an off the shelf forced air refrigeration system. Probably better ask "Who invented the air conditioner?", because thats what it was.
1812
The introduction of the 1st mechanical calculator was invented in Europe. This type of calculator production then spread world wide. The first ever was invented by Willhelm Schickard.
The first mechanical pencil was invented in Britain in the early 1820s, and patented by John Hawkins and Sampson Mordon in 1822.
It was invented in Middle Ages. Around 1300 AD.

In the late 1800's a German student names Paul Gottlieb Nipkow developed the first mechanical module of television. He was able to send images through wires with the help of a rotating metal disk. This was called the "electric telescope" and had 18 lines of resolution. In 1907 two inventors used the cathode ray tube with the mechanical scanner system to create a new system. American inventor Charles Jenkins in 1923 invented the first practical mechanical television system. British inventor John Logie Baird was the first person to transmit moving pictures through a mechanical disk system first used by Nipkow. This was done in 1926, but from 1926 to 1931 the mechanical television system was improved and by 1934 it was converted into the electronic system that is still in use today. All early TV was black and white and it wasn't until later color TV will be invented.

The first mechanical counting device was invented by Blaise Pascal in 1642. It was primarily used as an adding machine. It could add and subtract two numbers.
