Ok I am constantly on the
move for informative info on
Alternative Energy Sources. This evening, I
ran across a very
amazing article that discusses Eco Energy Sources from a new
angle. Today’s fun post is titled Kinetic Energy to Electric Generators? .
Question by Ray of Freaking Sunshine!: Kinetic Energy to Electric Generators?
I noticed that the formua for Kinetic Energy (KE=.5mv^2) results in Joules, and Joules can be converted into Watts/Kilowatts, which is the same unit of measure as the energy output of electric generators.
So my question is this: If you have an electric generator that is powered by Kinetic Energy such as Wind or Hydro power, is the calculation for how much energy the generator will generate simply the amount of kinetic energy multiplied by some “Generator efficiency” percentage? And if so what is that percentage called?
Best answer:
Answer by Robert A
Your physics is correct. There will be an overall efficiency for the turbine, (any gearbox) and generator in converting kinetic energy into electrical power. I am not aware that it has a special name.
The efficiency, however, will depend on the design, in particular of the turbine which is likely to be lower than the generator, and will vary with the operating conditions.
What do you think? Answer below!
