How familiar are you with tornadoes?
DCIKey Insights
- Extracting energy from tornadoes and hurricanes is still a theoretical idea, fraught with technical and ethical hurdles.
- Efforts to tap into these extreme weather events could endanger human lives and disrupt environmental balance.
- Although the concept fascinates scientists, practical application is currently unrealistic and could be hazardous.
As the powerful winds and chaotic storms of an approaching tornado force you to seek shelter in a secure, windowless area, you can’t help but wonder if there’s a silver lining to nature’s fury. Could we potentially harness the energy generated by tornadoes and hurricanes?
To date, experts have not successfully harvested energy from these storms, but the concept holds promise if we can develop affordable and efficient technology to achieve it.
Tornadoes and hurricanes generate enormous amounts of energy. According to one scientist, a hurricane's energy output at any moment is roughly 200 times the global electrical generating capacity. However, this energy isn’t evenly distributed. These storms are chaotic, with much of their energy focused on sustaining the storm itself.
According to Chris Landsea, science and operations officer at the U.S. National Hurricane Center, the feasibility depends on the method of energy collection. For hurricanes, the majority of energy and heat is released during the condensation of water vapor into droplets. Currently, we lack the technology to capture this heat energy. Moreover, hurricanes spend most of their brief lifespan over the ocean, presenting numerous logistical challenges. Landsea notes that these storms can dissipate in as little as two days, and upon reaching land, they lose much of their power and energy.
Another idea involves positioning windmills in the path of storms to capture wind energy. However, there’s a significant hurdle: turbines would need to be both durable enough to endure the extreme forces of tornadoes and hurricanes and mobile enough to be strategically placed in the storm’s path. Currently, companies protect their equipment by deactivating wind turbines during storms to avoid damage or the risk of them becoming dangerous projectiles, as reported by a Scripps Howard News article.
Harnessing wind energy from storms would require technology like wind turbines to be both robust and portable—two characteristics that are typically difficult to combine.
The unpredictable nature of tornadoes and hurricanes makes it challenging to develop methods for harvesting their energy. Scientists are still grappling with fundamental questions about these storms, such as how and why they form so suddenly. Additionally, investors would require assurance that any proposed energy-capturing technology has a high likelihood of encountering these storms.
Currently, extracting energy from natural tornadoes and hurricanes is impractical. However, what if we could create smaller, artificial versions of these storms?
Inspired by tornadoes?
While we can’t contain tornadoes and hurricanes, could we replicate them on a smaller scale to harness their energy?
For tornadoes, this might be achievable in the future. Tornadoes gain power by channeling warm, low-pressure air from the ground into high-energy thunderclouds. Much of this energy circulates through the storm’s vortex, which moves unpredictably across the terrain. Instead of recreating an entire tornado, the idea is to create conditions that foster a vortex. You can even see a similar effect at home by observing water spiraling down a bathtub drain—it’s the same principle.
Engineers have drawn inspiration from these storms to develop controlled vortices, the intense energy spirals central to tornadoes (and even bathtub drains!). For instance, the Atmospheric Vortex Engine, conceptualized by a small engineering team, would feature a 328-foot (100-meter) tall, chimney-like structure where heat is applied at the base. By introducing steam, engineers aim to stimulate warm air to condense into water vapor, releasing heat and energy. The objective is to generate a vortex, which turbines near the structure’s top could convert into energy, as outlined on the project’s website.
Replicating tornadoes in a controlled setting has proven challenging. Since energy cannot be created or destroyed, scientists would need to input an equal or greater amount of energy to produce usable electricity. Additionally, replicating realistic tornado conditions is difficult. Tornado wind speeds can reach up to 300 mph (482 kph), according to the U.S. Federal Emergency Management Agency. Simulating such conditions would also require much taller structures.
Landsea emphasized that harnessing energy from tornadoes and hurricanes requires significant innovation. Until technology advances to match our ambitions, controlling these high-energy natural storms will remain a future endeavor.
