Windmill

• 1). Remove the tire from the rear bike wheel by cutting it free, then discard the tire.
  
  
• 2). Attach eight sections of rectangular sheet metal to the wheel spokes by tack welding them to the individual spokes, on the opposite side of the bike wheel's drive gears. The sections should be longer than the wheel is wide, over three feet but under five feet long. The width should be between 10 inches and 20 inches. Curve the end of each steel section like the blades of a fan, all in the same direction, by hand (use gloves). Each section should be angled about 25 degrees off of center when viewed longways. These are the primary drive blades, attached to a mountable, geared hub.
  
  
• 3). Slide the gears off of the wheel by turning the hub nut counterclockwise, then pulling each gear one by one. Leave the largest gear on the wheel, and discard the rest. Center the automotive pulley wheel to the center of the large gear and tack weld it into place around the very edge. Most auto pulley wheels will have an opening in the center to be mounted to equipment, and this will provide a hole to mount the windmill hub.
  
  
• 4). Mount the wheel onto a pole by driving the axle bolt through an opening and securing it on the opposite side. Any mounting position will do, on most surfaces, as long as the windmill is upright and pointed at the wind source. The internal hub bearings will allow the blades to spin freely, turning the gear and pulley wheel.
  
  

Alternator

• 1). Attach the alternator below the windmill on the same mounting surface, in this case a large pole, by tack welding an automotive alternator mount arm to the pole. Position the arm so that the pulley wheel of the alternator will line up with the pulley wheel on the windmill. The alternator should also be the correct distance from the windmill to accommodate the drive belt.
  
  
• 2). Bolt the alternator to the mount arm by turning automotive alternator mount bolts clockwise into opposing nuts.
  
  
• 3). Attach the drive belt to both pulleys by sliding them over the pulley wheels. The belt should be tight, with about a half inch of play.
  
  
• 4). Connect the output terminal on the alternator to a positive terminal on a battery by turning the nuts clockwise. Run a ground wire from the negative terminal on the battery to the alternator's housing (usually the mounting arm bolt will suffice), or directly into the earth with a long steel rod.
  
  
• 5). Connect an inverter to the battery for transforming the 12-volt DC power into 110-volt AC power by turning the battery's terminal bolts clockwise with the correct polarity inverter wire crimped in between.
