Engineering tall structures requires managing wind, earthquakes, and other destabilizing factors

Reinforced concrete, energy dampers, braced frames, flexible structures, and aerodynamic decks were among the methods implemented when building structures such as the Shanghai Tower, the Texas Super Skyscraper, and the South Rangitīkei Viaduct.

Due to their enormous size, wind turbines are assembled on-site using prefabricated components, advanced cranes, and vibration-damping systems to withstand the dynamic ocean environment.

Maintenance, curtailment, congestion, and wind speed can park a wind turbine

Wind turbines are optimized to operate at wind speeds between about 10 and 80 kph, but an internal brake stops them if energy is not required. Routine preventative maintenance and cleaning also prevent blades from rotating.

Carbon-neutral data centers may be possible if built within wind turbines

Wind turbine towers are typically hollow, housing only cables and a ladder for maintenance access. The excess electricity a wind turbine collects could power a stack of server racks more than 100 meters (328 feet) high within its tower.

High-altitude kites can perform airborne collection of energy from high-speed winds

Winds at high altitude are stronger and more consistent than those near Earth's surface, where natural and artificial barriers disrupt airflow. Kites pulled by the wind can extend a tether like a yo-yo, creating electricity in an attached ground generator.

Fiberglass and epoxy resin on blades complicate the recycling of wind turbines

Between 85 and 95% of a turbine's materials—except for the blades—can be recycled. Blades have been left in landfills when not repurposed into playgrounds and sheds, but new processes may allow them to be made into pellets for injection plastics and concrete.

Technological advancements will make future wind turbines more efficient and quieter

Manufacturing larger, more powerful turbines will result in future wind farms requiring fewer of them to meet energy demands. Larger turbines will meet these demands while rotating at lower speeds, reducing risks to avian wildlife.

Windmills can be designed to pump groundwater for irrigation or land drainage

A gearbox within the windmill converts the windmill's rotation into the vertical motion of a piston that pushes water up a pipe. It also drives the rotation of an Archimedes screw to move water to higher elevations.

Tornado chasers include scientists conducting field projects

Research teams use drones, mobile weather stations, and radar systems to capture real-time meteorological data, better understand conditions that favor tornado formation, and improve forecasting models. As of 2022, model limitations result in roughly 70% of tornado warnings being false alarms.

Explore an interactive graphic of a wind turbine's components

Wind turbines contain a gearbox that increases the rotation of the blades by a factor of 100 from low to high-speed shafts. The latter moves magnets that change the magnetic field within a generator, creating electricity.

Wind turbines are limited to capturing no more than 59.3% of incoming wind energy

In 1919, German physicist Albert Betz applied the laws of conservation of mass and momentum to airstreams to calculate the theoretical limit. However, real-world turbines only convert 35 to 45% of available wind energy into electricity.

Before Alex Honnold completed his free solo climb of Taipei 101, 'French Spider-Man' scaled the building

Alain Robert completed his climb of the massive skyscraper in 2004, 22 years before Honnold. The crucial difference, though, was that Robert used safety ropes for his ascent. Honnold, on the other hand, completed it "free solo," meaning he climbed the building without any equipment beyond some shoes and a pouch of chalk for his hands.

The carbon footprint of manufacturing a wind turbine is offset within seven months

Despite initial carbon emissions during manufacturing, wind turbines generate nearly zero pollution across their 20- to 25-year lifetimes. Offsets occur when turbines replace energy generation from coal and natural gas plants, which emit carbon dioxide.
