Camka's favourite invention...

For this article, we have to introduce an invention which for us is a revolutionary invention. For me, a revolutionary invention is an invention which is ingenious, who contribute to make our daily life better. We have seen on the blog the Suvir Mirchandani’s smart idea. Thanks to him, the US government have saved about $234 million !

So, I have decided to introduce the windmill. A windmill is a machine that converts the energy of wind into rotational energy by means of vanes called sails or blades. The reason for the name "windmill" is that the devices originally were developed for milling grain for food production; the name stuck when in the course of history, windmill machinery was adapted to supply power for many industrial and agricultural needs other than milling. The majority of modern windmills take the form of wind turbines used to generate electricity, or windpumps used to pump water, either for land drainage or to extract groundwater.

I think that windmill are good invention because thanks to that, in 2011, 3% of the french electricity was produce by the windmill. Moreover, this new market promise round 60 000 new jobs for french peoples. This market is growing in France and everywhere on the world, thanks to that, in few years, we can hope that all of the electricity of the world can be produce by the windmill.
