The Benefits of Typhoon-Proof Wind Turbines

Typhoon-Proof Wind TurbinesA Japanese energy startup called Challenergy is creating the first wind turbines that can withstand and harness energy from typhoons. The wind turbines are designed to help countries, especially in Asia, derive some benefit from frequent tropical storms. Typhoon-proof wind turbines could provide a solution to the challenges storm-prone countries often face when they have to shut down standard wind turbines because of typhoons. The robust design of typhoon-proof wind turbines could make renewable energy more accessible to developing countries where tropical storms are prevalent. Building the turbines could also create jobs and protect the environment, which benefits low-income communities.

Deriving Benefits From Typhoons

Atsushi Shimizu, the founder of Challenergy, told Reuters that a central goal behind creating the turbines is to turn typhoons into a positive. Tropical storms have historically caused ample damage to Japan and other Asian countries, but the typhoon-proof wind turbines could make the storms highly beneficial to people and the environment. Typhoons often destroy traditional wind turbines and put them out of service, but the design of Challenergy’s “Magnus Vertical Axis Wind Turbine” withstands and benefits from storms by harnessing powerful wind energy. The turbines could save people, energy and the environment by withstanding tropical storms and providing sustainable energy, even during typhoon season.

How Typhoon-Proof Wind Turbines Work

Challenergy designed the “Magnus Vertical Axis Wind Turbine” without the traditional pointed blades that are characteristic of wind turbines. The typhoon-proof wind turbines resemble egg beaters, featuring square, upright blades that spin horizontally in the wind’s direction. As a result, Challenergy’s wind turbines are sturdier and better able to capture clean energy from typhoons than traditional wind turbines.

Shimizu told CNN that Japan has often imported wind turbines from Europe, but they are poorly designed for areas with frequent typhoons. If Challenergy’s typhoon-proof wind turbines are successful, Shimizu predicts the turbines could provide enough clean energy to “power Japan for 50 years.” Challenergy is on its way to introducing a new, sustainable energy source to Japan and the rest of the world through its typhoon-proof wind turbines.

The Benefits at Large

Every year, Japan experiences around 26 typhoons and other tropical storms, which makes it difficult to maintain wind turbines and harness energy from the storms. Challenergy’s typhoon-proof wind turbines could provide a long-term solution to Japan’s current low capacity for wind energy. The turbines could create jobs in Japan and other countries and provide a reliable source of clean energy amid both normal and extreme weather conditions. Challenergy’s turbines offer a solution to the challenges of integrating clean energy in typhoon-prone countries. The turbines could help all parts of the world, regardless of climate, adopt sustainable energy sources to protect the environment, which everyone relies on to survive.

Challenergy is still testing its wind turbines to optimize performance, but nevertheless, the typhoon-proof turbines offer hope of a clean energy source that will cater to countries that experience an abundance of natural disasters. For many developing countries, this could mean a long-term energy supply that shows resilience in the face of frequent natural disasters in contrast to traditional wind turbines.

A Look at the Top 10 Worst Typhoons

Worst TyphoonsA tropical cyclone is a generic term for a rotating, organized system of clouds and thunderstorms that starts over tropical or subtropical waters and has a closed low-level atmospheric circulation. The words hurricane and typhoon both refer to tropical cyclones.

However, the word hurricane is used for tropical cyclones that form over the North Atlantic Ocean and Northeast Pacific, and the word typhoon is used for tropical cyclones that form over the Northwest Pacific Ocean. Typhoons are often seen as more destructive than hurricanes because they tend to hit the densely populated countries of Asia. Below is a list of the top 10 worst typhoons of all time.

Top 10 Worst Typhoons

  1. Haiphong – The Haiphong typhoon of October 8, 1881, was one of the most catastrophic events in history. It is the third deadliest tropical cyclone in history. The category of this typhoon is unknown since it occurred before the meteorological advances of the twentieth century. However, what is known is this gigantic typhoon was able to travel through the Gulf of Tonkin. As a result, it ravaged Haiphong, Vietnam and the surrounding coastal area, killing 300,000 people.
  2. Nina – Typhoon Nina, a Category 4 typhoon that appeared on July 30, 1975, currently holds the rank of fourth-deadliest tropical cyclone ever recorded. Most of the destruction from this typhoon came not from its devastating winds but from flooding triggered by the collapse of the Banqiao Dam in Zhumadian City, Henan province, China. The collapse of this dam also caused other smaller dams to collapse, which caused even more damage. The death toll is totaled at 229,000 people.
  3. Haiyan – Typhoon Haiyan formed rather recently in November of 2013. Haiyan was a Category 5 super typhoon that produced world record wind speeds of 315/km/h or 195/mi/h. It hit parts of Southeast Asia, especially the Philippines. With a death toll of 6,300, it is the deadliest Philippine typhoon on record.
  4. Vera – Out of the many typhoons Japan has suffered throughout its history, typhoon Vera was the strongest and deadliest. This Category 5 superstorm began on September 20, 1959. Through heavy rains, enormous waves and powerful winds, it destroyed thousands of homes, ruined crops and flooded rivers. In total, it left 1.5 million people homeless and took the lives of 5,000 others.
  5. Ida – The sixth deadliest typhoon to hit Japan was typhoon Ida on September 20, 1958. Landslides caused by this Category 5 super typhoon damaged or destroyed 2,118 buildings and swept away 244 road and railway bridges. More than 120,000 acres of rice fields were covered with two-foot tides. The Kano, Meguro and Arakawa rivers flooded and spilled onto piers and then destroyed houses, religious shrines, freight depots and stores. In addition to the 1,269 lives Ida claimed, it also left 12,000 people homeless.
  6. Sarah – Typhoon Sarah, another Category 5 super typhoon, formed on September 11, 1959. In Japan and South Korea, Sarah’s high winds and rain destroyed or damaged thousands of homes, ruined millions of dollars of crops, caused extreme flooding and left thousands homeless. There is no agreement among sources about casualties of Sarah. Some sources claim that 840 lives were lost and others claim that 1,869 lives were lost.
  7. Nancy – On September 12, 1961, the nations of Guam and Japan experienced the destructive power of typhoon Nancy. As a Category 5 super typhoon, Nancy hit the land with 215 mph winds. It currently holds the rank of the longest-lasting Category 5 equivalent hurricane in the Northern Hemisphere, and it took 191 lives.
  8. Wanda – The Category 2 typhoon Wanda in Hong Kong formed on August 27, 1962, until September 1, 1962. It is the most intense tropical cyclone on record in Hong Kong. Even though it was only a Category 2 typhoon, Wanda wrecked or damaged more than 2,000 boats and left 72,000 people homeless. There were 130 people who lost their lives in this tragedy.
  9. Megi – Megi, which is Korean for “catfish,” became a Category 5 super typhoon in the northwestern Pacific. It made landfall in the Philippines on October 8, 2010, and was one of the strongest typhoons on record. The impact of Megi was around 2 million people in 17 cities and 23 provinces of the Philippines. In addition to killing 69 people in the Philippines and Taiwan, it destroyed agriculture, infrastructure and more than 148,000 houses.
  10. Forrest – One of the fastest-moving tropical cyclones on record, typhoon Forrest developed in the Western Pacific on September 19, 1983. This Category 5 super typhoon damaged 46,000 homes in Japan. Although it was not as destructive, it is still responsible for 21 deaths.

The damage done by the top 10 worst typhoons reveals how vulnerable humans are to uncontrollable forces of nature. Humans have not yet developed the technology they need to shield themselves from all of a typhoon’s destructive effects though research efforts are ongoing.
