Provides water for 100 people.Requires hand operation no more than 4 days a month (due to insufficient wind speeds).Requires regular maintenance once a weekHas a system cost of $800.00.

We conducted a survey that included citizens of Ghana. Although we had initially hypothesized that price was very important, and that customers would prefer to spend time if it meant spending less money; our survey results did not agree with our hypothesis. Our respondents reported that they would prefer a greater initial cost if that meant it came ready to install. They desire a system that:

Engineering design optimization model seeks to optimize the total hydraulic output over the entire day. This can be done by utilizing the wind energy efficiently at the

widest feasible range of wind velocities. The key variable to achieve this is the torque on the shaft attached to the

rotor.

Economic AnalysisEconomic AnalysisObjective: Maximize water output over

the entire day

Objective Relationship Value

Amount of Water Pumped 250m4/day

Maximum Well Depth 30m

Minimum Operating Wind Speed 3m/s

Height of Rotor < 10m tall

Total System Cost $480

Simplicity < 50 different parts

Quality = high

Use of Recycled parts 20%

Efficiency 20% wind

Durability 10 yr. lifespan

Maintenance = Easy, routine

Weight < 300lbs.

Aesthetics = Appealing

Simple operation,

water is lifted by disks.

Hand crank mechanism for periods of insufficient wind.

Windmill rotor will turn this gear via a pulley system.
