Wind Mill Wind Turbine Solar Panel Inverter/HomeUPS Batteries
How Wind Mill Work
The power of the wind is captured and harnessed in two steps. Each step is easy to identify by simply observing a windmill in action.
First, notice how the fan turns. A windmill captures the energy of the wind with the large, circular fan, or "wheel", located at the top of the tower. When the wind blows, the fan rotates. This turning (rotary) motion is so commonplace that it's easily taken for granted. But don't. This is where the free energy of the wind is captured.
Second,look just below the turning wheel and notice a long rod moving up and down. This "sucker rod", is powered by the windmill's motor. This motor is a unique set of mechanical gears that converts the rotary motion of the wheel into a reciprocating (up and down) motion that powers the cylinder pump located deep underground.

How Wind Turbines Work
Wind is a form of solar energy. Winds are caused by the uneven heating of the atmosphere by the sun, the irregularities of the earth's surface, and rotation of the earth. Wind flow patterns are modified by the earth's terrain, bodies of water, and vegetation. Humans use this wind flow, or motion energy, for many purposes: sailing, flying a kite, and even generating electricity.
The terms wind energy or wind power describe the process by which the wind is used to generate mechanical power or electricity. Wind turbines convert the kinetic energy in the wind into mechanical power. This mechanical power can be used for specific tasks (such as grinding grain or pumping water) or a generator can convert this mechanical power into electricity.

How Solar Cells Work
You've probably seen calculators that have solar cells -- calculators that never need batteries, and in some cases don't even have an off button. As long as you have enough light, they seem to work forever. You may have seen larger solar panels -- on emergency road signs or call boxes, on buoys, even in parking lots to power lights.
Although these larger panels aren't as common as solar powered calculators, they're out there, and not that hard to
spot if you know where to look. There are solar cell arrays on satellites, where they are used to power the electrical
systems.

How Hybrid Solar-Wind Systems Work
Wind speeds are often low in periods (summer, eventually) when the sun resources are at their best. On the other hand, the wind is often stronger in seasons (the winter, in many cases.) when there are less sun resources. Even during the same day, in many regions worldwide or in some periods of the year, there are different and opposite patterns in terms of wind and solar resources. And those different patterns can make the hybrid systems the best option in electricity production.
How Inverter/Home UPS Work
So how can an inverter give us a high voltage alternating current from a low voltage direct current.
Let's first consider how an alternator produces an alternating current. In its simplest form, an alternator would have a coil of wire with a rotating magnet close to it. As one pole of the magnet approaches the coil, a current will be produced in the coil. This current will grow to a maximum as the magnet passes close to the coil, dying down as the magnetic pole moves further away. However when the opposite pole of the magnet approaches the coil, the current induced in the coil will flow in the opposite direction.
As this process is repeated by the continual rotation of the magnet, an alternating current is produced.

Why you should build your own wind turbine? The reason is simply. It is because you get to save over 80% of your electrical expenses every month. Many families are affected by the current economic depression and with the present incident on the Swine flu H1N1 Influenza A virus, things are getting from bad to worst. With such crisis happening in the world today, it can be a breath of fresh air to see the cost of such items actually decrease for a change. You will have to make a small investment when you build your own wind turbine. Yet you will find it pays for itself in a matter of months.
