Design of a wind turbine kit for a car

Click For Summary

Discussion Overview

The discussion revolves around the design of a wind turbine kit intended for installation in a car or vehicle, aimed at recharging the car's battery or powering its components. Participants explore the feasibility, efficiency, and design considerations of integrating wind turbines into automotive applications.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant seeks guidance on starting the design project, posing questions about energy production from wind turbines, compatible vehicle components, and the choice between vertical and horizontal turbine designs.
  • Another participant emphasizes the importance of conducting independent research and suggests that the original poster should be able to answer their questions based on prior education.
  • Some participants argue that a wind turbine would be redundant and inefficient compared to the existing alternator system, which already recharges the car's battery using power from the engine.
  • There is a suggestion that a wind turbine could potentially be deployed only when the vehicle is parked, although this raises concerns about practicality, such as the need for a tall mast and limitations when parked in a garage.

Areas of Agreement / Disagreement

Participants express disagreement regarding the viability and efficiency of using a wind turbine in vehicles. While some see potential in the concept, others argue that it is unnecessary and inefficient compared to existing systems.

Contextual Notes

Participants have not reached a consensus on the practicality of wind turbines for vehicle energy needs, and there are unresolved questions about energy calculations and design specifications.

Hi!

I’m a 4th year student at mechanical engineering. I have been asked to design a kit that can be installed in a car/vehicle which can be used to recharge the car's battery or connected to some of the car's/vehicle's component to power them. Where and how do I start?
Does anyone have a books/articles which can be supportive at completing my project?

As a start, I considered the following questions:
What is the amount of energy can be produced by wind turbines?
What car/vehicle components can be synchronized with such kit?
Which is better to be used for this project? Vertical or horizontal wind turbine?
 
Engineering news on Phys.org
By the 4th year of an engineering degree, you should really be having a stab at these answers yourself. Do some bloody work, your 1st, 2nd and 3rd years of a mech eng degree should have taught you that (and how to conduct independent research and basic energy calculations yourself).

If you have specific technical questions which you need help with, you'll get all the help you need here. You won't get any marks for choosing a vertical design "because some guy on Physicsforums told me it was better".
 
A "kit" that recharges the car's battery already exists: the alternator. It takes power directly from the engine and turns it into electricity.

A wind turbine takes power from the wind, which is powered by the moving car, which is powered by the wheels, which are powered by the gearbox, which is powered by the engine.

Not only would a wind turbine be redundant, but also terribly inefficient considering the alternative (which is already installed).

Why a wind turbine?

You could always deploy the turbine only when parked... might need a good sized mast to get it up into the wind. Of course, it wouldn't work in a garage. :biggrin:
