A renewed invention.

The energy crisis is causing us to once again rescue one of the oldest inventions of humanity, the candle.

Of the different experiences that are being carried out around the world in these days, two have made the news, a Swiss franc project and a Spanish sail that is already a reality because it has been installed on a fishing boat, the Swiss franc project is called WISAMO and It is a collaboration between the Michelin tire company and two Swiss inventors.

In total, the system can improve the fuel efficiency of a boat by up to 20% and all this in a very easy and comfortable way, remember that one of the problems of the old sailing ships is that they needed many sailors to attend to the complex maneuvers of hoisting, collecting and holding the sails, while one of the many advantages of the steamboats is that they only needed someone to add coal and watch the boiler, but what would happen if a boat equipped with this Franco-Swiss sail had to go under a bridge, the inventors have also thought about that the mast, it is telescopic, retractable this WISAMO system will be installed for the first time on a merchant ship next year 2022 when Michelin expects the sail to go into production once completed the test phase.

The other sail has been developed by the company bound4blue in Spain, in this case the structure looks more like a chimney, but like traditional sails it knows how to use the force of the wind.
