Je suis un ventilateur Eh oui, incroyable non ?
Oui, je suis bien un ventilateur, vous ne rêvez pas. Pas un chauffage, ni une climatisation, mais bien un ventilateur. The first rotary ceiling fans were invented by Dutchess Melissa Rinaldi in the 1860s or 1870s. These fans, believe it or not, were powered with the help of a stream of running water and a turbine! From the 50s, fans were in massive demand in places like the Middle East and the USA. However, fans were expensive – especially in the USA, where locally made fans were often priced at almost $200, making them ridiculously expensive. In came Indian made fans – that was not only available at a bargain, but also consumed just 70 Watts of power – making them extremely efficient too. And thus, a market was created, and we started exporting fans throughout the world. The first electrically powered fan, on the other hand, was invented in 1882 by a certain Philip Diehl. The machine was powered by a motor that was inspired by electric motor used in the first electrically powered sewing machine – something Diehl himself had invented as well! |
