Japanese startup builds first wind turbine capable of withstanding tropical storms and capturing typhoon energy

Startup from Japan has developed a wind turbine that promises to resist and harness energy from typhoons and storms. The project has already passed its first challenge and fulfilled what it promised

The term “harnessing the power of nature” to generate electricity has often gained momentum, but what if there was a way to also harness destructive forces of nature like storms and typhoons? That's the proposal of an energy startup from Japan, which built the first wind turbine capable of withstanding tropical storms and capturing this tremendous energy in countries that are devastated by typhoons and storms, where ordinary wind power turbines have to be shut down.

Wind turbine promises to change the renewable scenario and cause fewer incidents

Japan faces around 26 typhoons and low-altitude storms on average annually and, therefore, the country's installed wind energy capacity is still small.

Challengergy founder Atsushi Shimizu radically changed the function and appearance of the traditional wind turbine to allow it to generate power under extreme storm and typhoon conditions.

The company Magnus Wind Turbine features large vertical blades that rotate around a horizontal axis, which is the complete opposite of the long, pointed blades that rotate on a vertical axis in conventional wind turbines.

Wind turbine that takes advantage of typhoons and storms faces its first challenge

The company's wind turbine wasn't up long before its first "test" arrived, Typhoon Kiko, a Category 5 storm with winds exceeding 249 km/h, the second strongest typhoon since 1987.

The wind turbine began its activities on the eve of the typhoon and continued operating normally until the early hours of September 11, when it reached its maximum power generation capacity of 11 kWh of net power, even in strong wind conditions. At 6 am, the wind turbine stopped its activities as it reached its maximum projected rotational speed, before the typhoon hole passed.

After the typhoon regained its strength, it became difficult to get speed data due to poor anemometer connection. Although the wind turbine exceeded the designed maximum allowable speed, there were no major damages and structural problems with the support arms or the tower. The cylinder and rectifier plate of one of the wings, however, were partially damaged due to a collision of flying debris.

Startup pronounces on the new wind turbine project

According to Shimizu, who founded the startup in 2014 after a Fukushima nuclear disaster inspired him to enter the renewable energy sector, one of the goals of the project is to turn typhoons and storms into a force.

According to the executive, if it is possible to partially take advantage of the enormous energy that comes from natural disasters, there are chances of considering them not only as disasters, but also as a source of energy.

The startup's first demonstration unit was installed on the island of Batanes, in the Philippines, a country made up of 7.600 islands that has serious problems maintaining rural power grids and has an average of 16,8 typhoons annually.
