Wind power is proportional to the cube of the wind's speed, so relatively minor increases in speed result in large changes in potential output. Individual turbines vary in size and power output from a few hundred watts to two or three megawatts (as a guide, a typical domestic system would be 2.5 - 6 kilowatts, depending on the location and size of the home).
Uses range from very small turbines supplying energy for battery charging systems (e.g. on boats or in homes), to turbines grouped on wind farms supplying electricity to the grid.
In Saddleworth, near Greater Manchester, an eco-war about wind turbines is waging. United Utilities want to build seven 350 foot wind turbines.
These will generate enough power to supply the average electricity needs of 8,500 homes in the local area. This wind farm is not situated out to sea but in the picturesque hills of the Saddleworth Moors and would be visible for miles around. Government targets state that 10% of the UK's energy should be supplied by renewable resources by 2010 and developments like the Saddleworth Moor turbines would contribute towards that total. Leading environmentalists from across the country have previously convened in Saddleworth for the first ever National Forum opposing the creation of wind farms on rural beauty spots.
World renowned TV botanist, Professor David Bellamy, joined former Downing Street press secretary, Sir Bernard Ingham and hundreds of activists at the National Wind Farm Group Conference. There were a total of representatives from over 50 environmental groups from across the country attending this event. It aimed to raise awareness about the perceived dangers of wind farms and bring environmental groups closer together in their fight against the government.
The Saddleworth Moors Action Group says the turbines would have a negative impact on a unique landscape. The group also insist their campaign is not prompted by "not in my backyard" sentiments, but through a genuine desire to preserve the character of the local area.
One could argue that the government is not bothered about the environment then they are continually financing the construction of coal fired power stations in the third world and building more airports and more motorways in Britain? As tensions are mounting in Iran and Nigeria leading to increased oil prices, is now not the ideal time to exploit wind power both on land and at sea via grants to companies? With labour slipping up at the local elections in 05/06 and the Conservatives pushing the eco argument, is not in Labours interest to follow the Conservatives lead and not to pay lip service to wind farms as they currently do?
OR
Will the people that have to live near wind farms and see the things every day change their minds and believe that wind farms form a concerted effort to save the environment or just another commercial money making scheme for the companies involved?

The Wind Farm Debate
Vertical Axis Wind Generators
The vertical axis wind turbine which is sometimes referred to as the (VAWT) for short, is a wind power machine that has been designed so that it maybe attached to a flat roof or stand on a platform in either the rural or urban environment. This type of generator has several advantages to it such as, because of the fact that it can be placed at the bottom close to the ground, the tower does not have to support the generator can be placed at the bottom, not only that but the turbine does not need to be pointed in the direction of the wind.
Although it certainly has its advantages, the turbine also has its disadvantages. Some of the disadvantages are that it is not an easy task to mount vertical axis turbines onto towers, because of this they normally have to operate slower and get the turbulent air flow close to the ground, which results in a less efficient energy extraction.
They only produce roughly 50% of the energy that a horizontal wind generator produces. They also have to be installed on a flat piece of land nothing steep and although steepness of an area might be a problem for a vertical wind generator, that is not a problem for a horizontal wind power generator.
However, like I said before it is not all negative there are also many advantages. Some of these include that seeing how the rotor blades are vertical, you do not have to have a yaw device so this reduces the need for a bearing and its cost. Vertical wind power generators can be at lower heights which can be useful when having to deal with laws that have certain height restrictions to them. Finally, smaller vertical wind generators are much easier to transport.
How to Build A Hydrogen Fuel Cell
Hydrogen power has garnered all the hype these days and if you think that people are not using it, then you're quite wrong. In fact, more and more people are now looking for a limitless supply of clean and usable hydrogen fuel. Have you finally decided to get a hydrogen fuel cell for your vehivle? If your answer to this question is a yes, read on to find out how.
There are a lot of advantages in building a hydrogen fuel cell. One is that it is cheap. If you're looking for a cost effective energy source, make it hydrogen fuel. The fuel cell does not require a huge amount of money or resources. The parts of the hydrogen fuel cell can be obtained from the hardware store in your locality. Even if the hydrogen fuel cell is a powerful system, the parts are fortunately inexpensive and not very complicated.
Another advantage is that the fuel cells are not complicated. In fact, the process is quite easy. You will the following in building the fuel cell:
1. Quart-sized water container
2. Vacuum hose
3. Electrical wiring to be used in connecting the car battery to an HHO generator
4. Baking soda
If you don't want to trouble yourself in purchasing the materials one by one, you can also buy HHO car kits. You can get the kits online or major local stores.
Once you have the different materials needed to build the fuel cells, you should be able to put them together properly. This is not hard to do as long as you have decent handyman skills. Building rocket power is definitely easy as compared to rocket science. The hydrogen fuel cells as mentioned awhile ago are not complicated and if you purchase the kits, it is equipped with step by step instructions in building the fuel cells.
So what's it going to be? Are you going to purchase the materials one by one and later on research for the procedure on the net? Or are you going to opt for the HHO car kits? The choice will greatly depend on the individual. Oftentimes, price is a great factor when choosing between these two options. Well, it's all up to you now. Just make sure that you choose the most cost effective way.
If you choose to purchase the materials one by one, you still need to find the needed information on how to build the hydrogen fuel cells. This is not a big problem and you have the internet to thank for. You can find all the needed resources online to help you build the fuel cells. You can print the instructions to guide you every step of the way.
On the other hand, if you opt for the HHO car kits, you hit two birds with one stone. All the materials needed to build the fuel cell are included in the kit and you don't have to research online for the instructions because it also included in the kit.
If you want to enjoy an unlimited supply of useful and clean energy, build your own HHO fuel cell now. As long as you know how to read and comprehend, you can build the fuel cells in no time. If you want, you can also ask help from friends and other family members.
