Seismic liquefaction threaten the safety of suction bucket foundations supported offshore wind turbines. The shaking table tests for sandy seabed - suction bucket - offshore wind turbine
Sand liquefaction under seismic load causes severe failure of bucket foundations for offshore wind turbines. This study conducted shaking table tests for two different types of
On the contrary, the shaking table test studies on seismic performance of wind turbine towers using TMDs are relatively scarce. One of the most famous shaking table tests of a full-scale wind turbine (65-kW rated

A pole-shaped wind turbine, Vortex Bladeless, generates power by shaking. Vortex Bladeless has designed a technology that is an alternative and innovative way to turn wind energy into power...
Madrid-based SME Vortex Bladeless, which led the project, is now targeting the local distributed energy market, enabling renewable power to be harnessed close to the point of consumption using its compact bladeless wind-powered
Vortex Bladeless is designed to solve the problems of traditional wind turbines, such as operational costs, noise, and impacts on birds. Owing to its simple shape and light weight of 15 kg, its material costs are reduced.
It’s a promising technology still in its infancy. When people think of wind power, most imagine rows of giant turbines stretching across wide expanses of land. David Yáñez envisions something else entirely. Yáñez is co-founder of Vortex Bladeless, a Spanish startup.
Vortex Bladeless Ltd. was founded in 2012 by David Yáñez and Raul Martín. A video inspired them to develop the generator. It was a video of the Tacoma Narrows Bridge in the USA that collapsed in 1940, showing how the bridge’s frequency resonated with that of the vortices caused by high-speed winds resulting in its collapse.
Vortex generators (VGs) can effectively delay air separation occurring on the inboard-section of the wind turbine blade. Many scholars have investigated the principle of VGs in terms of flow control and validated their ability to enhance efficiency.
Studies have proven that VGs can effectively delay stall angle, increase CL.max and L / D, and lower the LER sensitivity of airfoils. VGs can markedly enhance the AEP or power output of wind turbines as per wind site experiments and CFD analyses.
NIMBYism is one of biggest threats to the transition to renewable energy. So silent, small designs could make a big difference to installation rates. Nicknamed 'the Skybrator' by the internet, a bladeless wind turbine has been designed to generate energy from its vibrations alone.
The European energy storage market is booming with Germany leading residential adoption (+58% YoY) thanks to €500/kWh subsidies. Italy's new tax credits drive 5.2GWh commercial deployments, while UK grid-scale projects exceed 8GWh with 2-hour duration systems. Key selection criteria: German-certified safety (VDE-AR-E 2510), 10+ year warranties, and VPP readiness. Top-performing products include Sonnen's hybrid inverters (98% efficiency) and BYD's Blade Battery (12,000 cycles @80% DoD). For snowy regions like Scandinavia, consider Huawei's -30°C compatible systems. France mandates carbon footprint declarations - Sungrow's ISO-14067 certified solutions gain preference.
For European homeowners, 5-10kWh systems with 3-phase compatibility are ideal. Top picks: 1) Tesla Powerwall 3 (13.5kWh, 97% round-trip efficiency) for smart home integration; 2) LG Chem RESU Prime for compact urban installations; 3) SMA Sunny Boy Storage for retrofit projects. Critical features: EU-made battery cells (exempt from CBAM tariffs), dynamic tariff optimization (like Octopus Energy integration), and fire-safe LiFePO4 chemistry. Southern Europe demands 85%+ depth of discharge capability, while Nordic markets require -25°C operation. Always verify CEI 0-21 compliance for Italian grid connection and EnWG certification for German feed-in.
