At least that is what an Israeli company thinks. The certain company figured out a way to transform the gas emissions into energy.

Specialists at Haifa want to install, on their roads, generators that will collect the polluted gases that cars leave behind and transform it into electricity. But their initiative has some practical problems, as these generators should be placed beneath the layer of asphalt.

The results however would be spectacular. A generator placed beneath one kilometer of asphalt could produce 500kw per hour, enough energy to sustain more than 800 households.

Their discovery is by all means a great one and would indeed have spectacular results. The question that remains unanswered is “would any country reconstruct their entire infrastructure for this” ? Hopefully, they will realize how much this could help the planet and give it at least a second thought than simply saying no to it as soon as they hear about what it takes to do this. Even though many people might have blamed car washing companies for not being at all safe for the environment, they actually are.

Regarding commercial car washes, these, as any other business, want to make money. The main thing every car wash needs is, well, water. Therefore, water is the thing they pay for the most. This lead to creating special systems that control the amount of water used in a single wash, thus being more cost effective to run and economical for the water suply.

Yes, but most of the people that say car washes aren’t good for the environment aren’t necessarily talking about the amount of water used, but about where the water goes after being used, filled with dirt and cleaning chemicals. Well, they will be glad to learn that, for the same reason - that of cutting the costs down, most car washes have private recycling systems through which they reuse the same water over and over again for a number of cars.

Apparently, washing your car at a commercial car wash takes 45 gallons of water. Washing your car by yourself at home takes between 80 and 140 gallons of water. The cleaning chemicals infested water at a car wash is recycled and does not go back into rivers or lakes, damaging the Eco system, as for the waste water resulted from someone washing its car at home, goes untreated into the environment and causes environmental damage to lakes, streams and river eco-systems.

Now with Spring just around the corner and sunny days ahead, most of you will wash their cars. Keep these things in mind before deciding between washing your car by yourself or paying a few dollars more and taking it to a car wash. You will be thanked by your children’s children.

Solar Water Heating

admin | Other | 0 Comments

Solar water heating systems are a great way to effectively conserve energy and reduce your energy bill.

Contrary to popular belief, this is not a new technology. Solar water heating systems have been used commercially for over a century now, with the first commercial water heater (the Climax Solar-Water Heater) going on sale in 1891 in the United States. By the year 1900, over 1600 houses in California were equipped with this solar water heater.

Due to its effectiveness and low cost, the solar water heater gained popularity until, by 1941, more than half the population of Florida was getting its hot water through solar water heaters!

It only lost its popularity as a result of lowered electricity rates, and an aggressive campaign by Florida Power and Light to increase electrical consumption. This was done by offering electric water heaters at bargain prices. Thus Florida’s solar water heating was brought to halt.

The United States is not the only country with a history of heating its water using solar power. There are many other countries where this heating method was used in the past, and has since fallen out of use, - but not all of them. In fact, there are currently more than ten million Japanese households which heat their water using solar heating systems. This is definite proof that it is a workable technology.

Important Facts about Solar Water Heating Systems:

  • A solar water heater can reduce your water heating bill by 50%-80%. But with energy prices going up, the amount of savings will soon be even higher.
  • Solar water heating will significantly reduce your carbon footprint, and reduce the demand for fossil fuels which pollute the environment.
  • Solar water heating can be used in any climate. Sound unbelievable? Check it out on the U.S. Department of Energy website. They say so as well.
  • Solar heaters can be installed in combination with backup systems. In fact, you could install a solar water heater next to your existing system and make it possible switch to conventional water heating whenever necessary. This way you are guaranteed always to have hot water.
  • Aside from reducing your energy bill right now, a solar water heating system will protect you from future energy price increases. Your heating will no longer rely on fossil fuels for electricity.
  • The fuel used to run a solar water heater is sunshine. And, at the time of this writing, sunshine is free - no tax has been added yet.
  • When building a new home, or when refinancing, the economic aspect of this becomes even more interesting. You can, for instance, include the cost of a solar water heater with a new thirty-year mortgage package. This would usually amount to about $13.00 -$20.00 a month. Federal income tax deductions for mortgage interest would reduce the payment for the solar water heater by about $3.00 -$5.00 per month. If your fuel savings with a solar water heating system is $15.00 or more per month (which it likely will be) you will have reduced your monthly heating bill right then and there.

Types of Solar Water Heating Systems

There are two types of solar water heating systems, active solar water heating systems and passive solar water heating systems. They both work on the same principles.

The only difference is that active systems have a pump or other mechanical means of moving the water through the solar heating systems, and passive systems rely on nature’s principles: warm water rises to the top, and cold water sinks to the bottom. Therefore, with a passive solar water heating system, the water storage tank must always be positioned above the solar water heater collector.

Active Solar Water Heating

There are two main designs of active water heating systems. Which one is best for you depends on the type of climate you live in.

There is what’s called an “indirect circulation system” which uses a non-freezing heat-transfer fluid to transfer heat from the collector to a heat exchanger (a device used to transfer heat from the heat transfer fluid to the water in your storage tank). This is good for colder climates.

There is also the direct circulation system, in which case water is simply passed through solar heat collector and is then routed to the water storage tank for use. This system works fine in milder climates.

Passive Solar Water Heating

Passive solar water heating systems are usually cheaper than “active solar water heating systems,” as they do not need controls or pumps to circulate the water.

But generally, they are not as effective as the active systems. If you live in a warm climate, a passive water heating system may be all you need. Passive water heating systems are also known for being very reliable.

Essentially, solar hot water heating systems consist of a water storage tank and its solar collectors. The solar collectors are used to collect solar energy (which heats water), and the tanks store the heated water. That’s all there is to it.

Every time there’s an increase in oil prices, people feel it, even if they don’t drive a car. Some suggest we use biofuel to lessen the impact of the rising fuel costs.

But what is biofuel, and how does it differ from fossil fuel?

Biofuel is produced from recycled elements of the food chain, and from plants. It is used in vehicles, and is considered a sustainable renewable source of energy, as compared to majority of the liquid and gas fuels which are used today. Conventional fuels are fossil-based, and there are limited sources available. These sources are depleting fast, and if we don’t find a good replacement, one day our cars will basically stop running.

Types of Biofuels

Biofuels can be used in their pure forms, or they can be blended with other fossil fuels. There are two basic types: biodiesel, and bioethanol. These are currently available on the market and most engines are compatible with them. There is no need to modify one’s existing engine in order to use them.

Biodiesel

This type of biofuel is created using a process that combines oil with alcohol, in the presence of a catalyst, to produce either methyl or ethyl ester. The alcohol used can either be methanol or ethanol. The esters are then blended with the standard diesel fuel, or can be used in their pure forms (100% biodiesel). Biodiesel can replace diesel, or it can be combined with it in such a way that it helps run diesel engines with little or no modifications required. Biodiesel is said to be better for the environment because of the fact that it produces fewer emissions, while at the same time being made from renewable supplies.

Bioethanol

Bioethanol is made by oxygenating various agricultural stocks, such as sugar and starch crops. It can be used in existing engines, although a small quantity of conventional fuel is needed for cold starting. Vegetable ETBE is used at present, as a fuel additive that can enhance octane rating. The vegetable ETBE is a replacement for MTBE, which is made from unsustainable sources.

Controversy

Biofuel might appear to be a promising renewable energy solution, but there are still some issues that need to be addressed regarding its use. While its use may lower the level of carbon emissions on the planet, the production of biofuel has caused debate. The concern is whether crops should be used for fuel or be reserved for use as food.

Hopefully these problems can be resolved. Biofuel might be an inexpensive and renewable source of energy, but people certainly shouldn’t starve because of it.

Small Wind Generators

admin | Other | 0 Comments

With the world’s ever-increasing demand of power being more than its supply, it is about time that we take concrete steps to save power. Apart from being conscious about the usage of power and water at home, one can employ pollution-free and cost-effective power solutions at our homes. Solar power solutions and wind power solutions are the two of the most efficient solutions that can replace the conventional power solutions employed at our homes. wind generator plans are needed to make wind power.

These solutions can help you combat power outages, reduce your electricity bills, and also help the environment.

This article will explore the cost-effective wind power solution that you can employ at home.

Wind power solutions work best when the following conditions are met:

* You have a house or farmhouse spread over a big area. Typically, wind power solutions are employed in areas that spread over an acre.

* The average wind speed in your area is around 11 miles per hour. If you stay in a place that has little wind flow, your system will not work. Consult an expert before installing the wind power solution at home.

* You need to draw water from external sources. You can install a wind power system even when you do not need to draw water from outside. However, if you need to draw water from outside on a regular basis, a wind power system offers the best solution.

* Your house needs a lot of uninterrupted power supply. Combating those power outages is easy with the pollution-free wind power systems. You need no longer worry about a break in your work because of a power uncertainty.

A typical wind power system comprises of a tower and five blades to churn out wind energy. The length of the wind tower varies depending on the location of your house. You may need a longer tower if you are in low-wind zone; you can work with a shorter tower if you live by the beach. Using a wind generator plans, this wind energy can be converted into useful electrical energy to be employed at home for running various electrical appliances. You can even store the power generated for later use, making wind generators more efficient than convention power systems.

If you are confused with the wind power jargon, here’s a piece of information for you. The terms, wind mills, wind turbines, and wind generators are used to refer to the same machine.

How Solar Energy is Created

Solar energy consists of the light and heat emitted by the sun, in the form of electromagnetic radiation.

With today’s technology, we are able to capture this radiation and turn it into usable forms of solar energy - such as heating or electricity.

Although one could go into technical dissertations on the subject of electromagnetic radiation, how it is converted into solar energy, and the exact qualities of its electromagnetic rays, this is not something the average person needs or wants to know.

But in order to benefit the most from the use of solar power, there are a few facts you should know. Knowing these facts can assist you to make a sound decisions, when looking at the use of solar power as a clean energy source for your home, RV, or whatever the case may be.

Available Solar Resource

The technical feasibility and economical viability of using solar energy depends on the amount of available sunlight (solar radiation) in the area where you intend to place solar heaters or solar panels.

This is sometimes referred to as the available solar resource.

Every part of Earth is provided with sunlight during at least one part of the year. (I say “part of the year” as the north and south polar caps are each in total darkness for a few months of the year.) The amount of sunlight available is one factor to take into account when considering using solar energy.

There are, however, a few other factors which need to be looked at when determining the viability of solar energy in any given location. These are as follows:

* Geographic location

* Time of day

* Season

* Local landscape

* Local weather

Because the Earth is round, the sun hits its surface at different angles, at different locations on the globe. This ranges from 0? (just above the horizon - a good example of this is the north pole during the winter) to 90? (directly overhead, at and near the equator).

When the sun’s rays are vertical (directly overhead), the Earth’s surface gets a maximum of solar energy. The more slanted the sun’s rays are, the longer they have to travel through Earth’s atmosphere before reaching the surface (becoming more scattered and diffuse as they go along).

The more scattered and diffuse the sun rays are, the less concentrated the solar energy is. Because of the fact that the Earth is round, the polar regions never get direct sunlight, and, during their respective winter months, they receive no sun at all.

The Earth travels around the sun, in an elliptical orbit. Because of its elliptical path, the northern hemisphere of the Earth is closer to the sun during one half of the year, and the southern hemisphere is closer during the other half of the year.

When one part of the Earth is closer to the sun, it receives more concentrated solar energy. This is the time of year that is referred to as “summer.”

But regardless of summer or winter, the 23.5? tilt of the Earth’s axis plays a larger role in determining the amount of sunlight striking Earth at a particular location. The tilting of the earth results in longer days in the northern hemisphere during one half the year, and longer days in the southern hemisphere during the other half of the year.

Areas such as the United States and Europe receive more solar energy between May and September - not only because days are longer, but also because the sun is almost directly overhead during this season. The sun’s rays are far more slanted during the shorter days of the winter months. Cities such as Denver, Colorado, receive nearly three times more solar energy in June than they do in December.

Diffuse and Direct Sunlight

As sunlight passes through Earth’s atmosphere, some of it is absorbed, scattered, and reflected.

The following is a general list of materials that cause the sunlight to be diffused:

* Air Molecules

* Water vapor

* Clouds

* Dust

* Pollutants

Sunlight affected in this way is referred to as diffuse solar radiation or diffuse sunlight.

Sunlight that reaches the Earth’s surface without being diffused is called direct beam solar radiation or direct sunlight.

The sum total of all diffuse and direct solar radiation in a given location is called global solar radiation. It is the total amount of sunlight hitting the Earth at any specific spot, both direct and diffuse combined.

Pollution and other atmospheric conditions (such as weather patterns) can reduce direct sunlight by 10% on clear dry days. They can reduce direct beam radiation by 100% on thick, cloudy days.

Note that the absence of direct sunlight does not imply total darkness, as some diffuse light will still get through.

Measuring Sunlight and Solar Energy

Scientists measure the amount of sunlight available in specific locations during the different times of year.

They are then able to estimate the amount of sunlight which falls on similar regions at the same latitude with similar climates and conditions.

Measurements of solar energy are normally expressed as “total radiation on a horizontal surface”, or as “total amount of radiation on a surface tracking the sun”.

In this last case, the assumption is that one is using a solar panel that automatically tracks the sun.

In other words, the solar panel would be mounted on a tracking device so that the panel would remain at right angles to the sun throughout the day.

This system is primarily used for industrial setups, when it is used at all.

Solar Energy Measurements

Radiation data (the amount of solar energy available at a given location) for solar electric (photovoltaic) systems is often represented as kilowatt-hours per square meter (kWh/m2). Direct estimates of solar energy may be expressed as watts per square meter (W/m2).

Radiation data for solar water heating and space heating systems is usually represented in British thermal units per square foot (Btu/ft2).

Anna supports of clean living and the use of renewable energy in order to combat pollution and Global Warming, as well as the humanitarian and economic consequences of dependency on fossil fuels.

Slip back in time 30 years and you’ll see that the green movement was positively against nuclear fuel. It seems strange that 30 years on a number of the very same people are placing their hopes on nuclear power to stop the global warming Crisis. It could well be that we have no choice other than to go Nuclear but we have to ask the question “why aren’t we placing more emphasis on cleaner types of energy?” Some governments (Denmark is a case in point) have already come a long way in utilising cleaner and safer types of energy including both wind farms and solar power systems. They have had great success so you have to ask why other countries are favouring Nuclear Power?

The old concerns about using Nuclear Power have by no means gone away. It is still a form of energy with inherent dangers and we still have no viable solution to getting rid of radioactive waste! What is holding us back from moving to other forms of energy?

The common argument is that the cost of moving to cleaner forms of energy is far more expensive than sticking with fossil fuels. But what of those unspoken costs staying with fossil fuels or switching to nuclear power?

It is common knowledge that our fossil fuel resources are running out. With the demand for energy on the increase there is only one possible result. More price increases! On the other hand, the renewable energy provided by the Sun, Wind and Water is free and will be there for a very long time.

Harnessing the power of alternative forms of energy may not be cost effective at this time but future developments will surely lead to greater efficiency. For instance, take solar technology. As semiconductor technology moves forward in leaps and bounds, solar panels are becoming ever more efficient. Not so long ago solar panels could only be utilised effectively in warmer climates. Today, we see them being used in many different environments. Indeed, the science of solar technology has advanced so much individuals are investing in their own DIY Solar systems. If people think it worth their while to plan and build their own solar power systems then why can’t it be done on a wider scale.

The financial considerations of sticking with fossil fuel energy resources is not just limited to supply. We will have to deal with CO2 emissions or the removal of nuclear waste material, a cost that will be with us for many years. Alternative forms of energy like solar, wind and Hydro power are all clean and pollutant free. Future generations will not have to pay for what we do now. The cost of short term thinking is a high price to pay for the future of the planet. Let’s keep nuclear power at a distance. The Sun would be far enough.

India is so large and diverse it is hard to classify it. India is, as you will no doubt know, the name given to the vast peninsula which the continent of Asia throws out to the south of the magnificent mountain ranges that stretch in a curve across the southern border of Tibet. Shaped like an irregular quadrilateral, this large expanse of territory, so richly deserves the name of a subcontinent.

Government controls on domestic investment have been largely abolished in the last 10 years, and since then it has been agreed that the public sector should wherever possible stay out of any endeavor that could be accomplished by private firms.

This has now led to a sense of optimism in which many view India as perhaps now still only in the initial stages of a long boom that could extend over several decades. However, India remains as a country with a vast army of unemployed. Many families depend on just one earning member for sustenance and survival.

We have seen other countries in the region go down the same road and eventually emerge out of mass poverty at the end of it. August, 2007, saw the 60th anniversary of Indian independence, so it is still a young nation.

The sub continent has always been, through history a land of brave and chivalrous rulers who patronized arts and architecture and had a real knack for rewarding the deserving people. There are many forts and palaces around the land that demonstrate this, and if you visit them they will open up a whole new range of experiences of the local culture, and a respect for old Indian traditions.

Unfortunately, India is generally not cost-competitive with China for low-tech manufacturing work such as producing toys and household goods, because resource india labor and transit costs are higher. However, high-tech manufacturers are diversifying to India for other reasons.

India is also poised to play a major role in the large-scale commercialization of renewable energy technologies and can offer technology transfer to other industrializing nations. The country has achieved installation of over 10,000 megawatts of renewable-based capacity. India has been said by some experts to be short on natural gas, and that is expected to last only until 2012.

Alternative fuel vehicles are making their mark! Otherwise known as hybrids, they combine the best of both worlds with respect to electrical and internal combustion engine models. Their function is not to be confused with rocket science either! Simply put, if they are not recharging off the battery, they are drawing energy from it.

It’s inevitable that these new types of cars are going to change the automotive landscape. Today’s alternative fuel vehicles, like tomorrow’s, will only be limited by the imagination and how serious the world is in keeping the planet safe for the following generations. The future is now and the horizon for alternative fuel vehicles looks bright and promising.

alternative fuel vehicles
When it comes to alternative fuel technologies, vehicles that are making their mark include Nissan, Lexus, Toyota, Honda and Ford Escort. The alternative power supply models are smart, sophisticated models that are both functional, environmental friendly and aesthetically pleasing to the eye.

As the world gets on board as a collective whole to combat the use of fossil fuels, alternative fuel vehicles will become the car of choice for many people. You won’t be giving up comfort or performance either! You’ll be getting the best of both worlds while stretching fuel mileage and making your heard-earned dollar stretch further.

Sorting through the type and models of alternative fuel vehicles that will fit you and your family’s lifestyle should present no great challenge. Your choices will include models that employ biodiesel, hydrogen, propane, electrical, and natural gas technologies. The challenge may be in finding a local alternative fuel station. Yet for those who are environmentally responsible, owning alternative fuel vehicles is a great place to start.

alternative fuel technologies
As alternative fuel vehicles become a part of the automotive mainstream, there will be a hybrid model for the needs of just about everyone. You can expect to see models with bigger and more powerful engines which will be capable of delivering power at the top of the charts.

There will also be vast improvements in performance and fuel economy. Why not be a part of the trend that saves the world for tomorrow?

Although it is much less expensive to initially get hooked into the local electric company’s grid than it is to set up and hook into wind turbines, in the long run one saves money by utilizing the wind for one’s energy needs—while also becoming more independent. Not receiving an electric bill while enjoying the advantages of the modern electrically-driven lifestyle is a wondrous feeling.

Electric bills and fuel bills are rising steadily - but the cost of wind turbine energy is zero, and the cost of installing and hooking up a turbine is steadily coming down as demand rises and more commercial success is realized by various companies producing the turbines and researching technologies to make them ever more efficient. In addition, people are moving away from the traditional electric grids and the fossil fuels for personal reasons including desire for greater independence, the desire to live remotely or rurally without having to “go primitive”, political concerns such as fears of terrorist strikes on oil fields or power grids, or concerns about the environment. Again, this motivation to get away from the traditional energy sources is the same one that causes people to seek the power of the wind for their energy, giving more business opportunities to profit from wind turbine production and maintenance, which drives their costs down for the consumers. In nearly thirty states at the time of this writing, homeowners who remain on the grid but who still choose to use wind energy (or other alternative forms) are eligible for rebates or tax breaks from the state governments that end up paying for as much as 50% of their total “green” energy systems’ costs. In addition, there are 35 states at the time of this writing where these homeowners are allowed to sell their excess energy back to the power company under what are called “net metering laws”. The rates that they are being paid by the local power companies for this energy are standard retail rates—in other words, the homeowners are actually profiting from their own energy production.

Some federal lawmakers are pushing to get the federal government to mandate these tax breaks and other wind power incentives in all 50 states. Japan and Germany already have national incentive programs in place. However, “A lot of this is handled regionally by state law. There wouldn’t really be a role for the federal government,” the Energy Department’s Craig Stevens says. And as might be imagined, there are power companies who feel that it’s unfair that they should have to pay retail rates to private individuals. “We should [only have to] pay you the wholesale rate for … your electricity,” according to Bruce Bowen, Pacific Gas & Electric’s director of regulatory policy. However, the companies seem to be more worried about losing short term profits than about the benefits, especially in the long run, of the increased use of wind turbines or wind farms. Head of the Center for Energy Efficiency and Renewable Technologies of California V. John White points out, “It’s quality power that strengthens the grid.”

Wind Power

admin | Alternative Energy | 0 Comments

Wind power is taking the energy generated from the wind and using it in more productive ways.  Wind turbines are a machine that can transform the kinetic energy found in wind and convert it into mechanical energy. Mechanical energy works with kinetic energy to balance into the mechanical system. When the mechanical energy is converted into electricity it can be called a wind turbine.

There are two different types of wind turbines; Horizontal axis and Vertical axis.  The most common of these two are the horizontal axis. Horizontal axis features the main rotor shaft and generator at the top of the turbine.  The horizontal axis is pointed into the wind. Most of these horizontal axis have a gearbox that allows the blades to turn quicker to generate more electricity.  The tower is what provides turbulence.  The turbine can be pointed somewhat upward and stand well above the blades.  The blades are made of durable material capable of withstanding high winds.

When you see these turbines in the field you may think that they are no longer helpful but there are several people who believe in using them still. Horizontal axis wind turbines can either turn upward or downward.  If they choose to turn the blades upward, they don’t hold good together for longer periods of time.  They begin to crack and breakdown in high winds.  When the blades are downward facing they stay in line with the wind longer and they can outlast through the high winds without breaking.  Because they are so durable it keeps the cost down as well.

Types of Horizontal Axis Wind Turbines

Windmills Consists of four or more blades, usually short, and can wooden blades. These were used to grind grain.  As the winds picked up it would rotate a mechanism inside allowing it to run the grain through a mill crushing it.

Rural Windmills was originally from Australia but later moved over to the USA.  Farmers found that this type of windmill was good to pump water and electricity to the barns and fields. This windmill had several blades and can still be seen today in fields.  They were constructed of metal usually in order to carry electricity for lights or maybe a radio.

Modern Turbines are what we have now standing in fields.  They feature three blades that are pointed at the ends. The reason for their unusual shape is because they have been proven to exceed wind velocity up to 6 times more, allowing for high efficiency and reliability.

The advantages of this type of wind turbine include stability, tallness, bendable, durable and strong.  The disadvantages my include cannot operate well close to the ground,  hard to transport over sea, difficult to install, not in big demand, there are concerns with how they affect radar, structural damage done with storms and wear.

There are good points and bad points to owning these types of turbines. They have been proven to work and you can have one or thirty one out in your field.  They do help to generate electricity and other great things that we would normally have to go without.
