Lower costs, cheaper wind turbines and hurricane safe. That’s the future of offshore wind energy promised by SeaTwirl, a company that makes vertical wind turbines. These new turbines have capabilities ...

Small vertical axis wind turbines (VAWTs) possess the ability to effectively operate in the presence of high turbulent flow, which makes them ideal energy harvesting devices in urban and suburban ...

The type of wind turbine you’re used to seeing in stock photos of wind farms is called a horizontal axis wind turbine (or, HAWT). But there is another form of wind power, called a vertical axis wind ...

Propeller wind turbines are the most common way of using one of the most abundant energy sources on Earth to generate electricity. The tall three-bladed fans are the ubiquitous symbol of wind energy, ...

The number of designs for vertical wind-power turbines is growing because they’re efficient, small, and cheaper to build than regular windmills. Sound familiar? One of the companies that seem to be ...

These scale model wind turbines use fixed-pitch blades to evaluate a new vertical axis wind turbine design. Vertical axis wind turbines are easier to install than traditional horizontal axis wind ...

Urban wind turbines face an up-hill battle, as many people feel they are too big, too expensive, and potential eyesores. However McCamley just unveiled a prototype for a new vertical-axis turbine with ...

A concept rendering of offshore vertical axis wind turbines (VAWTs). What makes renewable energy so exciting is the immense economic potential of groundbreaking technology advancements. A recent ...

Researchers at the UK’s Oxford Brookes University think wind turbines would be more efficient if they were designed differently. A team from the School of Engineering, Computing and Mathematics has ...

Vertical wind turbines get more interest as the Wind Show kicks off. This week's Windpower show in Dallas looks to host several kinds of wind turbines that depart from the traditional horizontal axis ...

A debate over whether it is best to harness wind energy with horizontal-axis devices or vertical-axis devices has raged for thousands of years. Even how the technologies evolved is under some dispute.

Offshore wind turbines have problems that include high construction and maintenance costs and the risk of toppling in high seas or strong winds, especially for floating turbines. These problems can be ...
