Home Wind Turbines
Welcome to homewind.net! Our website is dedicated to clean, sustainable energy sources, particularly wind power. The movement of air is an ever present force in our world, and it has the power to radically change the way we produce and consume power. The amount of power available for us to harness is currently in the range of 72 terawatts. This is more than four times the total annual power consumption of the entire world! So what’s stopping you from joining the wind power revolution?
Wind is known as the flow of air through the earth’s atmosphere. This air flow is created by the disparate heating of different portions of the earth via sunlight. In a planet that has over 70% of its surface covered by water, you might think that the difference in heat absorption would not be a significant factor. You would, however, be wrong. You see, before sunlight strikes the earth’s surface, it must pass through the atmosphere. The sun strikes the earth from the side, this means that at the equator, or in the tropics to be more precise, the sun has the most direct path to the surface. When sunlight strikes the poles, it must travel through hundreds of miles more atmosphere to reach the surface. This difference causes the air, ocean, and land to heat differently at the poles than the equator, and this difference in heat (and therefore pressure) is what causes the air to move.
Knowing what wind is; is one thing. Knowing how to harness it is a more useful thing entirely. The simplest way to harness its power for use is with the turbine, and more effectively for individuals, with home wind turbines. The mechanical basis for the turbine has been in existence for centuries, since the invention of the mill. A mill was originally intended to grind corn, wheat, or other grain into flour so that it could be used for baking. Early men sought to find more effective ways to run their mills. The one that we owe our current turbines to was known as the windmill. It had large blades that were set in a vertical wheel shape. The axle of this wheel was connected via gears to the mill stone, so that when the air turned the blades outside, it caused the mill inside to turn as well. The modern home wind turbine replaces the mill apparatus with a simple turbine.
One of the most effective ways to harness wind power is with a home wind turbine. These turbines are scaled to comply with residential structural codes and noise ordinances. Home wind turbines alone cannot power a house, because wind power is inconsistent in most areas of the world. However, a single can ease the grid drawn power a household utilizes, and if coupled with other forms of clean energy, such as solar power, home wind turbines can be part of a completely off grid home’s power network. Multiple turbines can even be connected with a battery storage system in a type of miniature wind farm for the household that wants to be completely reliant on air for power. One of the most impressive aspects of air as a power source is that once the turbine is in place, it operates at zero carbon consumption, making it an extremely environmentally friendly power source!
