The company's V2 turbines are based on the work of the Finnish engineer Savonius, who invented his eponymous Savonius wind turbine in 1922, but according to Venger, their V2 design is a big step forward from previous iterations of the unique vertical
axis turbine design.

Another key difference in ESRU's
design is that the
turbine has two rotors attached — one in front of the other that turn in opposite directions on a single
axis.
Although the efficacy of small wind
turbines, especially vertical
axis wind
turbines (VAWT), is often debated, and the
designs dismissed as not being worth their cost or manufacturing resources, but that hasn't stopped people from trying to improve them or apply them to niche uses.
(I have a
design I call the Cooke AquAero Motor which is a vertical
axis, cyclo -

4 Issue 4) that «offshore vertical -
axis wind
turbines offer the potential for a break through in offshore wind energy availability and reduced life cycle costs due to their
design characteristics of few moving parts and the sitting of the generator at the base level potentially allowing large - scale direct drive.
