Government bureaucrats require 96% efficiency for electric motors, by law. Nothing could be more ludicrous. Engineers have been working with an inviolable barrier at 40% efficiency for more than a century.
Heat is randomized atomic motion. Kinetic energy is linearized atomic motion.
Everything electrical energy does results in atomic motion being more randomized instead of less, which means heat increases. For that reason, no electrical energy transformation can save more than 40% of the energy as linear motion of kinetic energy. The maximum efficiency for electric motors has been recognized as 40% until recent contrivances claimed an increase. Now, quack numbers are being used to get 96% efficiency in electrifying transportation.
The government requires efficiency in the area of 96% for electric motors, and some talk exists of 98% efficiency.
These claims appear to be the source of the conflict with reality in the minds of persons who promote the renewable energy and electric vehicle causes. Being unqualified to clean a dog house, the promoters of the causes never tell us what the source of their stupid assumptions is. Does everyone know that electric motors get 96% efficiency? All electric motors have cooling fans or mechanisms to remove heat, because they never get more than 40% efficiency, and usually a lot less. To have encountered this highly visible fact of life is to be a flat earther living in a phone booth.
What fakes are doing now days is contriving numbers for the relationship between one form of energy and another, since the misdefinition of kinetic energy does not stabilize the relationships. A wide variety of numbers have been concocted for every purpose due to the muddle resulting from the misdefinition of energy.
Electric motors transform electrical energy into kinetic energy. All transformations lose a lot of energy to heat, which is inefficiency—always far more than the 96-98% efficiency being described for electric motors.
To create kinetic energy from electrical energy, an inductive force acts upon electrons in copper wires which exert a force on the metal around them. Force acting upon electrons or atoms creates a lot of heat. Heat is the same thing as kinetic energy which has been randomized in direction at the atomic level. Actual kinetic energy is linear motion. To get high efficiency, the motion must be almost all linear and very little randomized.
The randomization of motion at the atomic level cannot be prevented in creating linear motion. The number one reason is because all atoms and molecules are constantly vibrating when the temperature is above absolute zero. To get linear motion, every contact would have to by right in the center of an atom or molecule pushing it in the desired direction. But since the molecules are vibrating in every direction, many of the hits will be off-center and push an atom or molecule in some other direction. All of that "other direction" creates heat. It randomizes the motion of the atoms or molecules.
For this reason and several others, it is impossible to get more than about 40% of the energy directed linearly in the transformation of energy into kinetic energy.
