Discussion Overview

The discussion centers on the feasibility of using wind-powered turbines in cars, exploring concepts related to hybrid energy systems, efficiency, drag, and the practicality of such designs in varying wind conditions. Participants consider both theoretical and experimental aspects of wind propulsion in vehicles.

Discussion Character

  • Exploratory
  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant proposes building a wind turbine-powered car with an electric motor, questioning the efficiency of turbines as an energy source and the potential drag they might create.
  • Another participant suggests that a sail would be more efficient than a wind turbine for propulsion.
  • A claim is made that conservation of energy principles indicate a wind turbine cannot effectively power a moving car using its own relative wind.
  • One participant references existing wind-powered vehicles, such as the Ventomobile and Spirit of Amsterdam, which have achieved success in competitions, raising questions about feasibility in regions with low wind speeds.
  • Several participants agree that vehicles designed for wind propulsion might perform better with sails, potentially achieving higher speeds in favorable wind conditions.
  • A participant notes that wind power transmitted directly to the car shaft may be insufficient for effective electrical generation and propulsion.

Areas of Agreement / Disagreement

Participants express differing views on the practicality and efficiency of wind turbines in cars, with some advocating for sails as a superior option. The discussion remains unresolved regarding the overall feasibility of wind-powered vehicles.

Contextual Notes

Participants mention specific examples of wind-powered vehicles and their performance, but there are uncertainties regarding the impact of local wind conditions on the viability of such designs. The discussion includes assumptions about energy efficiency and the mechanics of wind propulsion.

use of wind powered turbine in cars ??

helloo.. I'm just thinking to build an wind turbine powered car using with electric motor like an hybrid car .. there are certain question arises in my mind are .. that the use of turbine as a source of energy will be efficient or just theoretical concept as will there be too much drag and will the power generated will be too less and how much of dia should i need of turbine blades for making an average small one person car ... and even I'm thinking of using regenrative breaking as Electric motors also allow us to use the magic of regenerative breaking .. will it be possible ?? and even will it be economical ?? please if any knows about it ..

You likely will be more efficient with a sail.
 


Conservation of energy says a wind turbine cannot power a moving car (utilizing its own relative wind).
 


yeah i know it totally can't depends upon it . but there are certain cars even like wind proppelled car racing oocurs every year like ventomobile designed by University of Stuttgart students. It won the first prize at the Racing Aeolus held at Den Helder, Netherlands.
and even these

The Wind-powered vehicle "Spirit of Amsterdam 1" and "Spirit of Amsterdam 2" is, just like the Ventomobile, a WPV build by the Hogeschool van Amsterdam (University of Applied Science Amsterdam). In 2009 & 2010 the Spirit of Amsterdam 1 and 2 won first prize at the Racing Aeolus held in Denmark .

The Spirit of Amsterdam 2 is the second vehicle built by the Hogeschool van Amsterdam. It uses a wind turbine to capture the wind velocity and uses mechanical power to propel the vehicle against the wind. This vehicle is capable of driving 6.6 meters per second with a 10 meter per second wind

check out it ..

i'm just asking is it feasible as in my country the air usually quiet slow ..
 


I agree, those cars would probably be better off with a sail. Then they could go 10m/s in a 10m/s wind.

They could go faster.

Most definitely. You ever see those Dutch bikes, Whikes? They cruise under constant winds.
 


Wind power is directly transmitted to the car shaft. This is too weak to allow an electrical generator and an electrical drive inbetween.
