How to convert movemnt/speed to electricity or other E.forms

Click For Summary
SUMMARY

The discussion centers on converting vehicle movement into electricity, primarily through the principles of electromagnetism and electromagnetic induction. Key methods mentioned include using Faraday's induced electromotive force (emf) and alternators, which charge vehicle batteries while in motion. The conversation highlights that while energy can be generated from vehicle motion, it results in increased fuel consumption due to energy loss from friction. The concept of "electric speed bumps" is also introduced as a potential solution for energy generation.

PREREQUISITES
  • Understanding of Faraday's law of electromagnetic induction
  • Knowledge of vehicle alternators and their function
  • Familiarity with energy conversion principles
  • Basic concepts of friction and energy loss in mechanical systems
NEXT STEPS
  • Research "Faraday's law of electromagnetic induction" for foundational principles
  • Explore the design and function of vehicle alternators in energy generation
  • Investigate "electric speed bump" technologies and their implementations
  • Study the relationship between energy extraction and fuel consumption in vehicles
USEFUL FOR

This discussion is beneficial for engineers, energy researchers, and automotive professionals interested in renewable energy solutions and the optimization of energy use in vehicles.

Hi
I was wondering if there is a way to produce energy using the movement of vehicles on the road. I do not know which principles can come into picture, but I believe Electromagnetism/ detection is the way to go?
If someone could at least throw me in the right direction of which field to research to find a solution, it would be awesome.

Thanks!

From movement to electricity... the first coming to me is Faraday's induced emf...
 
Batteries of vehicles are charged while they are running, using the principle of EM induction. An alternator is used for this purpose.
 
All of the energy lost by a car's motion is in various forms of low grade frictional heat, which is not recoverable. There are lots of ways to generate electricity from the motion itself, but all will require the engine make up for the additional loss. Using induction means, literally, pulling on the car with a giant magnet. You can also Google for "electric speed bump"...

If you take any energy out of a car in the form of electricity the fuel consumption will increase by a corresponding amount.
