could anyone help explain what a Golov turbine is and what does it do?

Answer 1

I think you mean the Gorlov turbine.
Gorlov's helical turbine is based on the so-called Darrieus turbine, developed for windmills in the 1930s. The original never proved practical. The design, with its straight airfoil blades, was efficient but unstable, tending to break easily because of extreme vibrations. When Gorlov tested it in flowing water, however, he found it worked better than any other turbine, although it still had vibration problems.

After laboratory testing, he found that twisting the blades into the shape of a helix, like a molecule of DNA, would solve the problem. In flowing water, the Gorlov turbine captures 35 percent of the water's energy, compared with 23 percent for a straight Darrieus turbine and 20 percent for a conventional turbine.

Answer 2

Answer 3

It's a turbine used to extract energy from flowing water.
