Mechanised vehicles are introduced to the battlefield Read more on the Popular Mechanics website. These cost a minimum of $10,000 ($120,000 in today’s money) when they were launched in 1932. Air conditioning remained the preserve of the wealthy for decades, despite the invention in 1931 of the conventional window ledge unit that we still see today. From the 18 th century onwards, Europeans and Americans experimented with various devices for mechanically cooling air, followed by an electrical air cooling machine invented in Buffalo, New York, in 1902.Īir conditioners were included in a private home for the first time in 1914, when a unit measuring seven feet high by six feet wide was installed in a mansion in Minneapolis. Most of their ideas were based on rotary fans operated by water or manual labour. Once again at the forefront of technology, the Chinese nation was the first to introduce mechanical air cooling. A New York Times editorial called this idea “absurd” and stated that Goddard “seems to lack the knowledge ladled out daily in high schools”. When Goddard published his results in 1920, he even made reference to sending a rocket to the moon. Physicist Robert Goddard spent two years, from 1912 to 1914, working on the idea of a rocket designed with separate stages, a separate combustion chamber, and with greatly increased exhaust speed. However, the concept behind the modern rocket was patented in 1914, during a period when scientists were inspired by sci-fi writers such as HG Wells and Jules Verne. The concept of the space rocket has been around for centuries, ever since Chinese warriors experimented with “fire arrows” hundreds of years ago. Here we present some of 1914’s most interesting scientific and technological advances, as we look forward to the New Year almost a hundred years later on.
