Vertical Wind Turbines Slated for UK Arena Installation (Int'l.)
Alpha 311
Date: 2021-03-17
In the UK, Alpha 311 reports its innovative vertical wind turbines are to be installed on the 20,000-seat O2 Arena in Greenwich making the arena the first in the world to trial the new turbine system. The Alpha 311 vertical turbine can turn with minimal wind due to its size, weight and unique shaftless design.

While currently still being manufactured, 10 of the new turbines could produce up to an estimated 87,600 kWhs a year, which is equivalent to the annual total electricity used by 23 British homes. (Source: Alphha 311, Website PR, 13 Mar., 2021) Contact: Alpha 311, Barry Thompson, CEO,

SeaTwirl Floating Vertical Axis Turbine Awarded EU Patent (Int'l.)
Date: 2020-01-22
Following up on our Jan. 10, 2018 coverage, SeaTwirl AB, the Swedish developer of a floating vertical axis wind turbine with folding blades, is reporting receipt of a patent from the European Patent Office (EPO) for its divisible offshore wind turbine. The European patent is in addition to earlier patents issued in Sweden, the USA and China.

The turbine is mounted on a buoyant underwater structure anchored in deep water. The wind turbine, tower and underwater structure are permanently joined and rotate as a single unit with water carrying the full weight of the structure which, similar to a sailing boat, is stabilized by the keel. The unit does not require a yaw system for the turbine to face the wind nor a pitching mechanism to turn the rotor blades. Accordingly, fewer moving parts incur lower maintenance and operating costs. The SeaTwirl S2, 1MW turbine is expected to be available in 2020. (Source: SeaTwirl, Offshore Eng., 20 Jan., 2020) Contact: SeaTwirl AB, Gabriel Strangberg, CEO, Managing Director, +46 70-480 55 29,
