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 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.
