Off-grid Wind Home Power

1. Why Wind Over Solar and Any Other Energy?

• The first is 24-hour a day power extraction is possible. Wind energy rises as the cube of wind velocity, so a steadier wind at the same average velocity provides significantly less energy than a variable wind. However, there are big benefits to consistent winds, such as reduced dependence on costly storage systems.
• The second is that raised wind turbines have essentially zero footprints and will not reduce top-deck area, which is needed for food production. Winds are stronger the higher you go above flat terrain, which is great for our seasteads that tower above the ocean. Experiments have shown that to raise a turbine from 18m to 30m increases power by 25%.
• Wind turbines can be built on farms or ranches, thus benefiting the economy in rural areas, where most of the best wind sites are found. Farmers and ranchers can continue to work the land because the wind turbines use only a fraction of the land. Wind power plant owners make rent payments to the farmer or rancher for the use of the land.
• Wind energy is fueled by the wind, so it's a clean fuel source. Wind energy doesn't pollute the air like power plants that rely on combustion of fossil fuels, such as coal or natural gas. Wind turbines don't produce atmospheric emissions that cause acid rain or greenhouse gasses.
• Wind energy relies on the renewable power of the wind, which can't be used up. Wind is actually a form of solar energy; winds are caused by the heating of the atmosphere by the sun, the rotation of the earth, and the earth's surface irregularities.
• Wind energy is one of the lowest-priced renewable energy technologies available today, costing between 4 and 6 cents per kilowatt-hour, depending upon the wind resource and project financing of the particular project.

2. Disadvantages:

• Wind turbines can be a bit loud, and elevating them out of the way involves guy wires - more difficult on a small seastead platform than land.

• Maintenance: it is difficulty to offer maintenance service for generator and blade and guy. But now GTE/JITE makes the hydraulic elevating tower to resolve this problem.

3. ABOUT SMALL WIND SYSTEM

• Wind Generator: it needs foundation to fix wind generator. It consist tower, blade, generator, Anemoscope and Dogvane.
• DC breaker: break off the wind generator for service and protection. Breaker need be with ground wire.
• DC lighting arrestor: protect system from lighting.
• Charge Controller: control battery bank charge and discharge reasonable and safety.
• Battery Bank: a single battery or multiple batteries connected together to create essentially one large battery of the required voltage and amp-hour capacity. In some ways the battery configuration and capacity are the most important electrical power decision to make, and a wise choice can help guarantee a steady supply of electrical power as well as a system that is simple to operate and maintain.
• DC/AC Inverter: A power converter that inverts” the DC power from the battery into AC power. The characteristics of the output signal should match the voltage, frequency and power quality limits in the supply network.
• AC lighting arrestor: protect system from lighting.
• Inverter Power Box with breaker: to break off AC and DC of inverter for service and protection.
• AC Load Power Box with switch to control AC load.
• Accessories: power cable, manual.
