INTRODUCTION

Wind power is the conversion of wind energy into a useful form of energy, such as using wind turbines to make electrical power, windmills for mechanical power, wind pumps for water pumping or drainage, or sails to propel ships.

Page 3: Wind energy car

Wind-powered mechanical vehicles primarily use wind turbines installed at a strategic point of the vehicle.

The wind power, which is converted into mechanical energy through gears, belts or chains, causes the vehicle to propel forward.

In this problem we are supposed to construct a car, which can be able to drive straight into the wind. The car has to be propelled just by wind energy, which means that we can not use others energy sources to move the car.

Objective :

Page 5: Wind energy car

The principle of the electric car is to transform the kinetic energy into electric energy (using a dynamo moved by a weather vane). Then, it would transform, with an electric engine, this electric energy into mechanical energy that would make the car walk.

Principle

Frontal Area: It is important to have the smallest frontal area (not considering the weather vane area). Air resistance force depends on the frontal area of the car. Smaller frontal area have smaller resistance (wind buoyancy), which is capable to reduces the car final speed and, consequently, the car efficiency.

The weather vane size: The total torque on the weather vane determines the driving speed of the car. A bigger vane will have a larger torque on it, and, consequently, the car will drive faster into the wind. However, a larger weather vane has more contact surface area, thus it will have more resistance force, which tends to push back the car. So, we need to find a optimum size that delivers a maximum torque and a minimum resistance force.

Wheels: There are four wheels in our car: Two are moved, indirectly, by the wind (motored wheels) and two wheels (not motored) have the function of equilibrating the car (this wheels are located at the back of the car). Below we show a drawing of the wheel’s arrangement.

Wind Source: In our experiment, we will use a fan as the wind source. Our fan has three different powers: it means that there are three possibilities of wind power (three different wind escape intensities). For a more complete resolution, we will utilize all powers to calculate the efficiency.

Wind direction: The efficiency depends on the direction that the wind blows at the car frontal area. For a better performance, we used a step to put the fan, so we had a better wind utilization (picture)

Efficiency:Classically, in general problems, we calculate efficiency as the ratio between the effective energy used to our purpose and the total energy available. Ratio equal to 1, means the system has a 100% performance.

On land :

Terrestrial wind-powered mechanicals includes Ventomobile, and Spirit of Amsterdam. The Mercedes-Benz Formula Zero uses solar cells, batteries, and a sail.

The Green bird, which currently holds a world record for fastest wind powered vehicle, is sail powered.

Ventomobile

The Ventomobile is a solely wind powered lightweight three-wheeler designed by University of Stuttgart students. It won the first prize at the Racing Aeolus held at Den Helder, Netherlands, in August 2008. At the Aeolus race, several universities from all over the world participate in race to build the best and fastest wind powered vehicle

Spirit of Amsterdam

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

Mercedes-Benz Formula Zero

Unlike traditional racing, which focuses merely on the order of finish, Mercedes' new concept introduces energy efficiency as an integral part of the competition. The Formula Zero Racer is loaded with technology designed to extract the maximum thrust from the electric hub motors, aero-efficient solar skin and high-tech rigid sail.

Green bird

Ecotricity's Green bird vehicle, designed and piloted by Richard Jenkins, broke the land speed world record for a wind-powered vehicle in 2009.“Green bird recorded a top speed of 126.4 mph (203.4 km/h), and sustained a speed of 126.2 mph (203.1 km/h) for the required time of three seconds, beating the previous, American held, record of 116 mph (186.7 km/h), set by Bob Schumacher in the Iron Duck in March 1999 at the same location.

Blackbird

The Blackbird is an experimental land yacht, built to demonstrate that it is possible to sail directly downwind faster than the wind (DDWFTTW).

Advantage

Generate energy from wind turbines and drive an electric car.

 The wind is free and with modern technology it can be captured efficiently.

Once the wind turbine is built the energy it produces does not cause green house gases or other pollutants.

Wind turbines have a role to play in both the developed and third world.

Page 21: Wind energy car

Disadvantage

The strength of the wind is not constant and it varies from zero to storm force. This means that wind turbines do not produce the same amount of electricity all the time. There will be times when they produce no electricity at all.

Wind turbines are noisy. Each one can generate the same level of noise as a family car travelling at 70 mph.
