Talk:Screw turbine

Article Title

The screw turbine is not a well-known term for this technology. It is recommended to change the article title to "Archimedes screw generator/turbine"

Kinetic energy and efficiency

Deleted the comparison of efficiency with water wheels.

• Screw turbine efficiency between 60 and 80% Research Gate. water wheel.
• Another source [1] states "Mean plant efficiencies were 69% and the six top.performing plants achieved peak efficiencies above 75%. The concept of the rotary screw turbine was evaluated. In the main experimental tests of seven different screw designs efficiencies of up to 94% were recorded."

whereas an overshot or backshot wheel can achieve efficiencies in the 80 to 90% range

I also change "kinetic energy" to " work". The terms have well defined meaning in physics and engineering.
