Have you ever thought about building your own wind turbine? It is not as simple as making your own solar panels but it is not hard either. Making your wind turbine look nice is a bigger problem than making electricity from it. The first thing you have to do is get a set of plans to make a wind turbine and then set about buying all the components.

Assembling the components is easy. The bits and pieces can be picked up cheap from vehicle scrap yards and your local DIY store. Just imagine being even only 50% self-sufficient in electricity? Add in a few solar panels or a second wind turbine and you could soon be off the grid altogether.

Everyone knows about the continually increasing cost of electricity and that it would be a good idea to create energy from the wind and the sun just for the cost of the generators – the wind turbines and the solar panels – so you may be wondering why it is not a good idea to just go out and buy what you need from a professional installer.

Well, the answer to that is expense. Professionally installed wind turbines can cost tens of thousands of dollars and it can take 20 years to recover the cost. On the other hand you can make your own for between $200 and $500.

If the turbine saves you $200 a month then it is obvious that you will have recouped your outlay within three months maximum, if you make the turbine yourself. This is a very good incentive as with a little regular maintenance it will last you 15-25 years. Let’s just say 15 years or 180 months at at least $200 per month. That is $36,000 or an 7,200% return on capital.

Wind generated electrical power is very green as it requires practically no fossil fuels to produce it. I say practically none, because it may need a little engine oil to keep the blades turning efficiently. And that is it. You may have to replace a bearing from time to time, but that is the extent of your maintenance routine. It is not severe. You will also have to put some water in the batteries from time to time as well, unless you buy the sealed models, which you cannot fill up.

It really is not so hard to build a wind generator. The average DIYer can complete this project with everyday tools. There are detailed instructions and plans available on the Internet or at DIY stores to manufacture a wind generator in your workshop or home.

So why not start to make yourself a wind turbine today? Fix it on a roof or a pole and start generating your very own free electricity. You could be off that grid more quickly than you know it and you will be doing more than your bit to help the planet too.

If you want to read more about home-made wind turbines and solar panels, there is plenty of advice on the Internet.

There are various reasons why you might want a hybrid car. You might like a hybrid car in order to cut your ever increasing petrol bill; in order to reduce your personal impact on the environment or you may just like the kudos of driving a car that is at the vanguard of technology. Naturally, it could be for a combination of all three reasons as well.

Hybrid cars have been around for around ten years and so the technology is quite well advanced. The thing to keep in mind is that hybrids are not performance cars in the conventional sense of the word. In the perspective of cars, the word ‘performance’ normally means ‘high speed’, but hybrid cars are performance cars because they save more than eight percent on the fuel bill.

They make this saving by basically using two engines. The one engine is a conventional internal combustion engine (ICE) and the other is an electric motor. Both engines deliver their power through the same mechanical means to the wheels. The ICE generates electricity and supplies it to a battery, like any car does, however, a hybrid car can use this battery power to drive the car as well.

The electricity is generated by alternators and the braking system. Regenerative braking supplies a large amount of power to the batteries. In fact, so much so that under normal driving conditions, the batteries do not have to be charged from the national grid.

The ‘early’ hybrids used the electric motor just as an ‘assist’. In other words, while the petrol engine would usually require to be revved up to produce enough power to overtake or go up hill, the electric motor would jump in to assist it, thereby saving fuel, but the petrol engine is effectively running all the time. This a form of halfway hybrid. The Honda Insight was one of these.

However, a full hybrid will use one or the other or both of the engines, depending on how its computer best interprets the power requirements of the driving conditions. The driver has no decisions to make, engines are turned on and off automatically and seamlessly by the car’s on board computer. Examples of this sort of full hybrid are the Toyota Prius and the Ford Escape Hybrid.

Although most individuals think of hybrids as new technology, the first hybrid car was manufactured more than a hundred years ago. Modern hybrids are around ten years old and the technology is improving quickly. However, what really has to happen now for hybrids to create a real effect on the amount of oil that the West consumes is for the prices to come down.

And I mean actually come down a lot. Hybrid cars are way too costly for the average driver. If manufacturers reduced the price of the cars, more people would purchase one which would stimulate the economy and aid the balance of payments deficit to say nothing of the effect of burning less fossil fuel would have on the environment.

If you access the Internet, you certainly need anti-virus software. It does not matter whether you do not use a computer. Whatever you use to get on line you must have anti-virus software. Although there are hundreds of malicious idiots producing viruses to attack those who access the Internet from a computer, there is an growing number who are targeting mobile phone users too.

It is harder to clear viruses from your mobile phone as well, because there are less vendors for the anti-virus software and mobile phone users are often less technologically knowledgeable than computer users, although the technique of clearing the virus is fairly analogous.

Let’s just use the example of using computers to go on line. If you go on line, your ant-virus software is your most essential item of software. It does not matter what you use the Internet for – transferring data back to base or receiving emails from friends – you are subject to attack.

For instance, if you use the Internet only to communicate with your head office, a hacker could try to piggy-back your link to gain access to the mainframe at head office and possibly access financial or other personal data and if you just send to and receive emails from your friends and family, you are open to attack from malicious fools around the globe.

If you use webmail such as that provided by Yahoo, Hotmail and MSN to name only the most popular, you will be protected from the most obvious attacks, but still not safe. If you obtain your email via an email client such as Outlook or Outlook Express, then you do not even have that small amount of security.

If you do not use email, but only surf the Internet for research or whatever, you are still not safe, because some websites and loaded with viruses, trojans and worms, waiting to unload them onto unwary surfers.

Therefore, whatever reason you surf the Internet for, you could do with some type of protection. Fortunately, anti-virus software for personal use is inexpensive and may even be free. Business users will normally get tax relief on their purchases.

However, be cautious with the free anti-virus software, because not all of it is effective enough. The exceptions that spring readily to mind are Avira and AVG. These are excellent items and have rightly achieved worldwide acclaim. Just Google the two names to get the download address.

The anti-virus software that costs something (typically $25-$50 per annum) invariably offer one to two months free trial before you buy and a reduction in price, if you pay for more than one year at a time. Names that fall into this class are Kaspersky, McAfee, Norton and Nod.

After you have chosen your software, the following steps are the same for free and paid software. First install it and then configure it. If you are not sure how to do that do not be concerned, the default settings are fine for the vast majority of users. The only choice you will get that it is vital you make properly is to consent to automatic updates.

New viruses are being exposed or fixed every day and for your anti-virus software to be effective, you must allow it to bring itself up to date whenever it wants to.
