William Cullen at the University of Glasgow demonstrated the first artificial refrigeration system in the year 1748. However, he never used his discovery for practical purposes. In the year 1805, US inventor Oliver Evans, designed the first refrigeration machine that didn't use liquid and instead used vapor to cool. -
electricity
Building upon Franklin's work, many other scientists studied electricity and began to understand more about how it works. For example, in 1879, Thomas Edison invented the electric light bulb and our world has been brighter ever since! But was Benjamin Franklin really the first person to discover electricity. -

In the late 19th century, a couple of scientists made pivotal discoveries, without which the first television would not have existed. In the 1920s, over 50 inventors from Japan, Britain, Germany, America and Russia were all seriously attempting to build televisions, many of which had very promising demonstrations.
