Step 1: Get Some 25mm ID / 50mm OD Bearings. Go get at least 2, or ideally 4 ball bearings with a 25mm (1inch) inner diameter, and a 50mm (2 inch) outer diameter. I bought mine for aout 6 Australian Dollars each at my local bearings store. Prise the side seals off and scoop out all the grease, then rinse the bearings out with some diesel or ...

turbines include vertical axis or horizontal axis wind turbines. The turbines are classified upon how the shaft of the generator is mounted. The horizontal axis wind turbine HAWT was invented before the vertical axis wind turbine (VAWT), which led to its popularity and wide use. Figure 1.2 shows a diagram of these two types of systems.

The vertical axis turbine is designed for urban environments having windy conditions. Having a diameter of 8m and a height of 3m, the turbine can generate up to 175MWh per year. Being vertical axis the turbines are safe for birds and are also less noisy when compared with the horizontal axis counterparts.

A water pumping windmill is simple, and efficient. The blades of the windmill wheel catch the wind, which turns the rotor. … A typical windmill with 8′ diameter wheel can lift water 185 feet and pump about 150 gallons an hour in 15 to 20 mph winds when using a 1 ¾ "pump cylinder. How much does a windmill water pump cost?

Vertical Axis Wind Turbine (VAWT) A wind turbine cannot be a wind turbine unless it has few blades. Likewise, the horizontal axis turbines, vertical axis ones also have a set of blades. But instead of spinning horizontally, they spin vertically. So, the rotational axis of a VAWT is in the vertical direction, and that's why it got such a name.
