User Needs

Helping the environment

Wind energy is a clean fuel source

Supply is abundant Using a cost effective system

It takes about 10-12 years for a 1.5 MW turbine

to pay for itself, assuming a 500 dollar/yearelectricity bill.


6/20

The Size of the Market

The 2009 Small Wind Global Market Study

found that the U.S. market share accounts

for $77 million of the $156 million globaltotal.


7/20

Competition

GEEnergy has around 50% of the US windturbine market

Others Include:

System Block Diagram

The sun unevenly heats the earthsatmosphere.

Uneven heating creates wind.

The wind turns the blades of theturbine.

The blades drags a conductor acrossa magnetic field

The magnetic field builds a chargeon the conductor.

The charge creates electricity.

Enabling Technologies

WindVAR

Automatically maintains specified voltage

levels

Advanced Electronics

Allows for continues adjustment of blade angle

Active DampingLessens tower ocilations

Functional Requirements

Wind Speeds

3.5 meters per second ( mph) to

25 meters per second (5 mph)

Temperatures

Operational

-30C (-22F) to 40C (104F)Survivable

-40C (-40F) to 50C (122F)

Product OperationBasically the opposite ofa fan

Blades are lifted by the

wind which causes themto move

Movement of the blades

is then converted into

electrical energy througha series of gears and a

generator

An Environmental Perspective

Creates no air pollution.

Steel, aluminum, and concrete, fossil fuels are used to create

a turbine but within 9 months of operation all the energy has

been paid back in full by clean power.

Wind farms do not require large scale construction and

demolition of the surrounding area so have a minor impact on

the immediate environment and unlike fossil fuels for

example coal which tears pits in the ground can be

considered an aesthetic improvement, rather than an eyesore.

Turbines Built Offshore offer a completely negligible impact

on the Environment.


19/20

Known Issues Lubricant and hydraulic fluid can leak if not properly

maintained and contaminate nearby drinking water.

Biggest environmental problem is with killing birds

and bats though it kills twenty times less birds than

fossil fuels.

In the UK only 1 bird a year is killed by wind

turbines.

It is unknown exactly how much of an impact

turbines have on bat populations due to the lack of

information on bats, but one solution has already

been put into place to stop bat deaths, which involves

installing a microwave transmitter on the turbine.
