Home Made Wind Turbine - How To Build Home-Made Wind Generators

By Caleb Carr


Learning how to build a home-made wind turbine became important to our family when we first started wanting to buy a wind generator to run our off gird home. The price of 1000w models needed to run our replenish-able energy system cost nearly $4000 including the tower. We had to even assemble it ourselves. We believed there must be a neater way.

Our solar panel array just wasn't sufficiently big to run our home and we figured a giant wind turbine would add to our power supply enough to meet the increased demand of three children growing up in a mainly normal home.

What did we need?

1000w of power production

40 foot tower

Could we build a home-made wind turbine?

We decided to have a look at the option of building our own, as we claimed when we saw the price of new ones. The difficulty was that no straightforward plans existed to do just that. All of the wind turbine plans we encountered requested complicated layout and much more welding than we cared to pursue. What we required was a simple set of plans.

None existed so we decided to make our own.

Our homemade wind turbine project took us over 10 years to complete. Attempting to find a source of inexpensive parts that we could put along with comparatively easy tools was really difficult. Everybody seems to always wish to complicate things so as to keep their share of an exceedingly big business sector. The renewable energy field has grown substantially over the past couple of years and most makers simply did not want anybody building their own wind turbine. I guess we can understand that.

But, not everyone can afford $4000 for the system we required. We know we could not. So we went to work to design a system that would be employed by anyone. We even learned ways to habitually offer a wind turbine blade design that met the easy tool- simple to learn criteria.

Do you want more information?

Learn how to build a home-made Wind Turbine. The plans are easy to follow, need simple tools only and no previous experience. It did take us over ten years to put together our testing and research so that the typical person could build their own; but we have still done our best to keep the price reasonable, under $30.

Excursion to Chernobyl and the Exclusion Zone

By Rob Atherton


At 1:23am on 26th April 1986, an explosion at the number 4 reactor of the Chernobyl nuclear power plant blew the roof open and sent a cloud of radioactive dust into the sky.

In recent times, agencies set about leading trips to the area in the region of Chernobyl. The full day tours set out from Kiev somewhere around 9am and these have to be booked in advance. Details of people on the trip need to be submitted and you have got to take your passport. If you are not on the list or you don't have your passports, the guards at the edge of the exclusion zone will not let you through as two people on our bus found to their dismay and had to disembark the bus. The checkpoint is just about 78km (49 miles) from Kiev and there is absolutely nothing to do there. From here the bus makes its way into the exclusion zone and doesn't return for several hours.

At the time of the catastrophe, Chernobyl was home to 14,000 people and today, a few hundred people still live in the exclusion zone and many people work in the town for around 4 days a week. The visit commenced in Chernobyl for a traditional Ukraine lunch. First stop is the fire station where there is a monument to the brave fireman who struggled to contain the radiation a lot of of whom died of radiation sickness.

Next stop is the Chernobyl power plant and it is here you have your first look of the disused structures. There are a handful of stops in and around the plant and you get to within two or three hundred metres of the reactor. Nowadays, it is tough to envision what occurred here but the guides Geiger counter leaves you under no illusions that there is still a large amount of background radiation in the area.

The last stop is at the ghost town of Pripyat which is situated no more than a couple of miles from the power plant. At the time of the catastrophe it was a much bigger city than Chernobyl with a population of approximately 50,000. Yet, authorities evacuated the populace with no warning and it is an eerie place to take in. Books lie all over the class rooms, the fun fair which was due to be opened on 1st May 1986, is gradually rusting away and nature has started to over grow the roads, town square and buildings.

The excursion leaves Pripyat and returns to the edge of the exclusion zone where everyone must pass through a scanner to make certain they haven't been exposed to abnormal quantities of radiation. Once everyone is back on the bus has been given the all clear, it travels back to Kiev.

Minor Holidays And Occasions In The USA

By Owen Jones


Below is a list of minor holidays and occasions in the United States. Some of them are practically unknown, and others are fairly obscure.

April Fools' Day - (April 1): the day for practical jokes (only before noon in the UK). Its origins are obscure, but it bears a similarity to an ancient Roman festival for the goddess of nature.

Arbor Day - (last Friday in April): devoted to trees and their preservation. It is held on December 22 everywhere else in the world.

Armed Forces Day - (third Sunday in May): a day to honour the US armed forces.

Citizenship Day - (September 17): replaced Constitution Day in 1952 by presidential proclamation.

Daylight-Saving Time: was first proposed by Benjamin Franklin in 1784, but became the Uniform Time Act in 1966. It is not observed in Hawaii, the Eastern Time Zone of Indiana, most of Arizona (except on the Navajo Reservation), American Samoa, Puerto Rico, the Virgin Islands and Guam.

Election Day - (Tuesday after the first Monday in November): presidential elections are held in years divisible by four and elections for all members of the House of Representatives and one-third of the Senate in years evenly divisible by two.

Fathers' Day - (third Sunday in June): was first celebrated in West Virginia in 1908, but this distinctively American holiday was not made official until 1972.

Flag Day - (June 14): was first observed in 1877, which was the centenary of the adoption of the modern design. Truman approved the Flag Day Bill in 1949.

Groundhog Day - (February 2): on this day the groundhog looks out of his burrow. If he sees his own shadow there will be six weeks of Winter to come, otherwise Spring is just around the corner.

Halloween - (October 31): All Hallow's Eve is the day before the feast of All Saints. It started as a pagan custom honouring the dead and a celebration of Autumn. 'Trick or Treat' is purely American with no historical basis.

Kwanzaa - is a secular celebration by African-Americans to commemorate their African heritage. It starts on Dec.26th when a candle in a candelabrum is lit every day for seven days. It was first observed by Maulana Karenga in 1966.

Mothers' Day - (second Sunday in May): was conceived by Anne M. Jarvis of Philadelphia as a way for children to pay tribute to their mothers. It received presidential proclamation in 1914.

National Maritime Day - (May 22): was initiated in 1935 to commemorate the SS Savannah's first successful transatlantic voyage by a steamship in 1819. It is also a day of remembrance of merchant mariners who died in defense of their country.

National Teachers' Day - (Tuesday of the first full week in May): is when students are meant to honour the teaching profession.

St. Patrick's Day - (March 17): has been borrowed from Ireland where it is their national saint's day.

St. Valentine's Day - (February 14): was originally to honour two saints martyred by Emperor Claudius (214 - 270), but has been devoted to lovers since the Middle Ages.

Susan B. Anthony Day - (February 15): Anthony (1820 - 1906) worked for women's rights and suffrage.

United Nations' Day - (October 24): commemorates the endorsement of the UN Charter in 1945 by the then five permanent members of the Security Council.

Are "Develop Your Own Solar Panel Kits" Worth Considering?

By Joe Sharp


Have you heard about the new build your own solar panel kits they're selling nowadays? They're actually quite straightforward to install and are very cheap once you get them going.

Solar power is definitely a superb source of alternative energy. It is renewable, thus it can't be exhausted. It leaves no by-products so it is environment friendly. The only obstacle it likely has is when it is clouded or wet outside; this could significantly affect its methodology of gathering energy.

It is possible to buy a kit over the internet and assemble it yourself. Transforming available and existing solar power into electrical energy may now be done right in your own home. Basically, the quantity of wattage that you select for your solar panels as well as the quantity of direct sunlight received will define the quantity of power that can be stored as potential energy.

One of the better things in having the ability to generate power by yourself is that if you've got an excess fuel, you may sell the excess power to electrical companies. This is called a grid on and grid off application. This puts you in a pleasing situation where you can sell electricity right back to your local utility district.

There are some topical issues to consider before making your call to install such a power system in your house. Buying solar panel kits is like making an investment, right? Now, when we try investing, we would like to recover them. Thus, it is vital to discern that once you make a decision to install solar panels in your place, you will not be moving out of that house before you've had the opportunity to get back your investment.

Ensure that a big portion of your roof is open to exposure to direct sunlight. This is terribly vital since solar cells react best with direct sunlight. If most of your roof area is being shaded by massive trees, then your panels will not be able to gather enough power. You might also want to check if your roof would be safe and snug enough for you to spend at least six hours in installing and wiring your panels. If you are not that assured working on your roof for that long, then you might want to hire someone else to install them for you.

Tips for Choosing the Best Figured Wood

By Curtis Cadenza


For those who may not be familiar with woodturning, I will outline a definition for it. This art form is an ancient process that began in the third century BC by the Egyptians. Since then, many refinements have been made to the tools used, but the concept remains similar. Woodworkers prefer using soft woods, such as Maple, for turning bowls and pens, as it is cut more easily.

Lacking a knowledge of trees would make it difficult to tell the difference between the unique varieties.

Figured wood, where the grain pattern is disrupted by swirls and whorls, is particularly valuable; in fact, due to its uniqueness and the quality, even a single board could cost hundreds of dollars. The most highly figured wood is used often for lids on jewelry boxes and other items that can show off color and texture. A skilled woodworker may consider a pile of stacked wood and envision the kinds of products that could be created from them. Those who are not knowledgeable of what a piece can produce, on the other hand, may think it to be simply an eyesore that should be burned or carted away. It can be difficult to tell the potential of maple and other woods until it is completed as a finished piece by an experienced craftsman.

You should take into consideration which species of tree is best suited for your particular craft, and the intended design that you are basing your creation on. Highly figured designs in the wood grain are extremely desirable, and add depth and color to wood objects.

One growth abberation known as a burl can be seen, usually on the lower trunks, of some trees. These types of growths are a result of unusual environmental factors that the tree experiences early in life.

Because of the beautiful textures and designs that appear as a result of burling, they are highly prized and often expensive, but work beautifully as a foundation from which large objects may be sculpted.

Maple is the most costly raw wood for woodturning projects. However, these types of wood, particularly in their erratic burl forms, can be used to produce artistic pieces of great quality. What may be seen as "defects" by many, a wood turner makes into beautiful works of art, which can hold great value, both monetary and sentimental.

Buying A Hybrid Car To Save On Gas

By Owen Jones.


As you pull up to the petrol station pump and fuel your car up with $10-$40 worth of gas, you may find yourself releasing a huge out sigh. How on Earth did petrol get to be so expensive? Should you consider one of those new hybrid cars you saw on the television? Everyone's talking about hybrid cars anyway. Hybrid cars and other types of cars may seem to be a good idea, but before you go out and do something you'll regret, maybe you should ask yourself some basic questions about how you can start to save on petrol.

There are so many options now including everything from not going out to purchasing a hybrid car, but you have to find out what is best for you. You can only do that by asking yourself the following questions.

Should you just drive less?

Sure, you could spend the rest of your life at home on the couch, but how would you eat then? I know what you're thinking you will walk more and get more exercise. That may be true, but what happens when you get bored with walking and riding your bike? How are you going to be able to get to the gymnasium? And, have you forgotten about work? You know you love listening to your books on tape while you sit in traffic at the end of the workday. Should you drive less? Probably not then. But what should you do? Well, have you ever considered buying a hybrid car?

Perhaps, I should buy a car that is more economical on gas?

Yes, you could do this, but what about when the vehicle starts to depreciate and it's not as fuel-efficient as you thought it would be? And subconsciously, because you know you have a car that gets more mileage out of fuel, you are going to start traveling more miles than you traveled before.

Should I get up earlier each morning to look for the cheapest gas prices in town?

Really, who has the time for all that? If you really think about it, you could probably spend your time better finding the right answer to the real question. Do you really want to spend extra time looking for a cheap fuel station? What would your boss think if you arrive late for work and tell him you were trying to save money on fuel? And anyway, how long do you think you'd keep that up?

Should I find a way to run my car on electric batteries?

Well, you certainly don't want to have to recharge your car every day before you go to work because that might make you late as well. With a hybrid car, you wouldn't have to worry about that. Therefore, the next question should be obvious.

How about purchasing a hybrid car?

Perhaps you should. It's possible that buying a hybrid car would be a wise method to avoid paying higher petrol costs. Will your car depreciate right after you drive it off the forecourt? A hybrid won't do that so quickly as it brings the buyer in more and more money as they save on gas. A hybrid car really could be a good solution here. However, it is always a good idea to conduct further research before buying a hybrid car.

What's Required For Green Construction To Be Considered Green?

By Jim Hokins


Most folks would say there are two components that produce green construction . The two items people will agree upon that produce a home "green construction" are the design and process and the finishing or "features" of the home.

The thing is, people don't know is that although these homes are green based on conventional building methods the fact remains that most of these homes could be greener than they are.

This is what quite a few people consider green construction.

FSC (Forest Steward Certified) Lumber - This is local timber that is provided from responsibly managed harvesting. Eco friendly paints Energy efficient appliances (Energy Star Rated) Energy efficient heating and air with programmable thermostats (Energy Star Rated) Tankless water heaters 2 x 6 exterior walls which allow for more insulation installation. Capture and reuse of rain and snow melt and gray water. Low flow or dual flush toilets Solar power Renewable resources such as bamboo flooring, blinds Solar tubes Awnings to protect windows and entries from extreme sun exposure Energy efficient windows and doors.

Here are the ways that the architect and general contractor design and build a home to be considered green.

The actual design of the structure to minimize waste of contruction materials. The design of the dwelling to take advantage of space for energy efficiency. Positioning of the house on the property on an east/west axis. Materials used i.e. renewable, green, recycled, improve energy efficiency. Methods of construction that will minimize impact of the land. Methods of building to reduce waste of resources such as power, gas, water, material, and man power. Methods used to reduce waste ending up in the dump such as donating unused construction materials to Habitat For Humanity stores, recycling metal and plastic and recycling wood to mulch operations or bio energy plants.

Yes these methods are green, there is no denying this fact. However, there are two important areas that are being unnoticed. The framing and the insulation are two areas that are being totally unnoticed. The framing and insulation are the two areas that are responsible for up to 80% of the homes heat loss.

The good news is there is a very simple answer for this problem. The first step would be to replace wood framing with steel framing. Instead of using insulation in the wall cavity and blown insulation in the attic you would use a radiant barrier sheathing. Finally, with a continuous ridged exterior insulation you are creating an air tight envelope around the home to prevent air infiltration. These three things combined can reduce utility bills by as much as 60%.
