When most of today’s wind projects were developed, first costs were the focus; operations and maintenance (O&M) costs were largely unknown. Now, with hundreds of turbine models in operation—sometimes ...

What is wind power density? The different types of generators used in wind-turbine systems. What architecture is most commonly used in high-power wind-energy-conversion systems (WECS)? Fundamental ...

Looking somewhat like a giant reed gently swaying in the wind, the new Vortexbladeless wind-driven generator prototype produces electricity with very few moving parts, on avery small footprint, and in ...

Hackaday editors Elliot Williams and Mike Szczys recap a week of hacks. A telescope mirror that can change shape and a helicopter without a swashplate lead the charge for fascinating engineering.
