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

Click For Summary

Discussion Overview

The discussion revolves around the potential methods for converting the movement or speed of vehicles into electricity or other forms of energy. Participants explore various principles and technologies related to this concept, touching on electromagnetism and energy recovery mechanisms.

Discussion Character

  • Exploratory
  • Technical explanation
  • Debate/contested

Main Points Raised

  • One participant suggests researching electromagnetism and detection as a potential field for energy conversion from vehicle movement.
  • Another mentions Faraday's law of induced electromotive force (emf) as a relevant principle for converting movement to electricity.
  • A participant notes that vehicle batteries are charged while running through electromagnetic induction using alternators.
  • Concerns are raised about the energy lost as frictional heat in vehicles, which is not recoverable, and the implications of energy extraction on fuel consumption.
  • It is mentioned that generating electricity from motion would require the vehicle's engine to compensate for additional energy losses, such as through induction methods.
  • A suggestion is made to look into "electric speed bumps" as a method of energy generation from vehicle movement.

Areas of Agreement / Disagreement

Participants express differing views on the feasibility and implications of extracting energy from vehicle movement, with some acknowledging the potential while others highlight the associated energy losses and increased fuel consumption. The discussion remains unresolved regarding the practicality of these methods.

Contextual Notes

Participants do not fully agree on the efficiency of energy recovery methods, and there are assumptions about the recoverability of energy lost to friction and the impact on fuel consumption that are not fully explored.

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.
