Biodiesel has been used as a fuel increasingly over the past years on account of oil crisis and high prices of the conventional fuel. Blends of Biodiesel and conventional hydrocarbon-based diesel are products most commonly distributed for use in the retail diesel fuel marketplace. A labeling convention involving “B” factor is used to state the amount of Biodiesel in any fuel mix.

For instance, fuel containing 30% Biodiesel is labeled B30, while the pure Biodiesel is always referred to as B100. B99 is commonly seen, because 1% petrodiesel is sufficiently toxic to retard mold. Blends of 20 percent Biodiesel with 80 percent petroleum diesel can generally be used in unmodified diesel engines. Biodiesel can also be used in its pure form, but may require certain engine modifications to avoid maintenance and performance problems.

Mixing of pure Biodiesel with petrodiesel may be accomplished by in-line mixing wherein two components arrive at tanker truck simultaneously or by mixing in tanks at manufacturing point prior to delivery to tanker truck.

The Biodiesel has calorific value of about 33 MJ/L which is 9% lower than regular petrodiesel. Moreover the variations in Biodiesel energy density are more dependent on the feedstock used than the production process. It has been claimed Biodiesel gives better lubricity and more complete combustion thus increasing the engine energy output and partially compensating for the higher energy density of petrodiesel.

The color of Biodiesel varies between golden and dark brown, depending on the production feedstock. It is immiscible with water, having a high boiling point and low vapor pressure.

Biodiesel is known to have better lubricating properties than the other currently available low viscosity diesel fuels. Addition of Biodiesel reduces engine wear increasing the life of the fuel injection equipment that relies on the fuel for its lubrication, such as high pressure injection pumps, pump injectors and fuel injectors.

Biodiesel can also be used as a heating fuel in domestic and commercial boilers, sometimes known as bioheat. Older furnaces may contain rubber parts that would be affected by Biodiesel’s solvent properties, but can otherwise burn Biodiesel without any conversion required.

The usage and production of Biodiesel are increasing rapidly. Fueling stations make Biodiesel readily available to consumers across UK, Europe, and increasingly in the USA and Canada. A growing number of transport fleets use it as an additive in their fuel and surprisingly in some countries; Biodiesel is less expensive than conventional diesel.

Approximately 85% of Biodiesel production comes from the European Union as the Global Biodiesel production reached 3.8 million tons in the year 2005.
It is suggested that waste vegetable oil is the best source of oil to produce Biodiesel, but the available supply is drastically less than the amount of petroleum-based fuel that is burned for transportation and home heating in the world.

Biodiesel has been popularly used in running the older models of Mercedes Benz and in due course usage of Biodiesel as a regular replacement to the conventional fossil fuels would most certainly revolutionize the world.

Bio-fuels are the latest alternatives to the conventional fossil fuels. Everyone is aware of the problems associated with the traditional petroleum based fuels and we all know about how expensive it is. Biodiesel is an alternative that can save your money big time and also help in keeping the environment unpolluted.

It’s about time you change the habit of spending all your money on filling gas for your car. Biodiesel can be made by using a Biodiesel kit.

Biodiesel kit is the required equipment for Bio-diesel production so as to use Biodiesel as an alternative source of energy for home consumption. You can use the kit to make your own Biodiesel, by means of an easy, safe and non-harmful process, or buy the full Bio diesel kit as well.

With fuel prices all over the place and your wallet getting emptier with every fill up, no wonder how quickly Biodiesel is getting incredibly famous. Moreover it gives you the capability to make it at home, which just makes the idea even better, no longer leaving you at the mercy of the big oil companies.

Biodiesel kit processor comes in several sizes and scales and therefore has wide price range. Before you think of buying a Biodiesel processor kit, you should check your needs, your required quantity and the frequency of usage.

For making Biodiesel on your own, you would need the Biodiesel kit, water, methanol and vegetable oil. Your can set up your kit anywhere anytime. Mostly people prefer to do it outside in a covered spot like a garage.

There are different choices in a Biodiesel kit. You should look for the one that will suit your needs in the best possible manner. These Biodiesel kits are absolute fun, although one of the main factors is the obnoxious odour it produces. A closed system will give off no odours but will cost more to purchase.

Biodiesel kits are becoming very popular, especially with people who are just using Biodiesel exclusively for all the purposes. People who have large amounts of used vegetable oil at their disposal take deeper interests in purchasing these kits. It takes longer to make Biodiesel using used oil rather than fresh oil. However it can be done either way without affecting the outcome.

The major reason that many people consider for buying a Biodiesel kit is its safety. The built in safety elements in a Bio-diesel kit are very handy. But make no mistakes in understanding that, it is a valid option to build the kit yourself.

Although while doing so, do ensure that you follow the detailed instructions from a reliable resource and avoid any accidents which could result in any disasters.

So try to keep the process of making Biodiesel safe and have fun making it with your hands sitting lavishly at home and it doesn’t really matter whichever way may you opt to do so. Save good bye to all your gas expenses and say hello to the greener world with the highly economic and green Biodiesel!

Fuel gas is a common term which refers to any of several gases such as methane ethane propane butane and the higher compounds, which are burnt to produce thermal energy.

Methane popularly known as natural gas is the most common fuel gas, while others also include Town gas, Syngas, liquified petroleum gas, Wood gas, Producer gas and Water gas.

In scientific terms, fuel gas is defined as a gaseous substance that burns in air and releases enough heat so as to be used as a fuel, while also remaining sufficiently stable at ordinary temperatures to permit long-term storage without deterioration or any hazards.
These fuel gases are good alternatives for domestic purposes such as cooking, while the other possible alternative options include the use of biogas.

Coal gas is a flammable gaseous fuel made from coal, which is popularly known as ‘Town gas’ referring to the manufactured gaseous fuels produced for sale to consumers and municipalities.

Depending upon the processes used for its creation, coal gas may be a mixture of many combustible gases such as hydrogen, carbon monoxide, methane and volatile hydrocarbons, along with small amounts of non-calorific gases like carbon dioxide and nitrogen, as impurities.

Coal gas has been extensively exploited in the 19th and early 20th Centuries for lighting, cooking and heating. Originally this is a by-product of the coking process. As development of fuel gas spread across all horizons, its byproducts, coal tars and ammonia, were considered an important chemical feedstock for the dye and chemical industry.

In past the coal gas plants were commonly referred to as the Manufactured Gas Plants or MGP’s by the environmental professionals.

Coal gas may be any of a variety of gases produced by heating coal in the absence of air and driving off the volatile constituents. But it is not as high in fuel value as other gases and often contains tars, light oils, ammonia, and hydrogen sulfide

It is also known as manufactured gas, hygas, producer gas, and syngas (SNG), in few countries, which is supplied via a piped distribution system to the user.

Natural gas occurs alone and in conjunction with petroleum deposits, which is an excellent fuel gas in wide commercial use.

Liquefied petroleum gas is a manufactured mixture of flammable gases that is easily stored in its liquefied condition. This is processed and filled up inside the gas cylinders which are used by millions around the world as cooking gas.

Oil gas is a type of fuel gas manufactured by applying heat to various petroleum distillates. Its principal use is as a supplement to natural gas during periods of heavy demand.

The fuel gas finds many other applications in the industry too; for instance a whole rainbow of artificial dye colours can be made from coal gas and coal tar.

It is advantageous if a fuel gas is readily transportable through pipes and is easily liquefied. Practically all fuel gases meet the first condition, and some meet the second as well. Hydrogen may also be considered as a fuel gas in the future.

Most of us waste a lot of gas and hence money just due to sheer carelessness. As the gas prices are ever increasing, you must try to save more gas by doing the needful. There are plenty of ways to save gas on daily basis; some of the good tips are mentioned below that may help you to surely save more gas.

As a matter of fact the gas consumption depends a lot more on your driving skills, so surely you must learn to drive smarter to save more gas. First thing is to avoid unnecessary stops. While approaching a red light, see if you can speed up enough and cross through safely, to avoid stopping at the signal. Speeding up from 15 or 25 mph will save more gas rather than starting from full stop.

Moreover start slowly from a full stop, as this is one trick that will have dramatic effects on your gas mileage. So don’t fancy a kick start from a stoplight, avoiding so may save a lot of gas.

Avoid idling because while idling, you waste a lot of gas. Factually starting the car uses the same amount of gas as idling for 6 seconds. Park your car and go into the restaurant rather than idling in the drive-through to save your precious gas.

Avoid idling with the air conditioning on to save some extra gas. Also try not moving so fast that you have to suddenly brake for someone, as while doing so, you waste the gas it took to get going that fast.

Stay away from store fronts as you will spend significantly more time idling and waiting for pedestrians and other vehicles to pass by. Use air-conditioners only on the highway, at lower speeds open the windows. Although it increases the drag and reduces fuel efficiency, it still helps you to more save gas in comparison to the usage of the air conditioners at lower speeds.

Learn to drive at consistent speeds. Avoid quick acceleration, hard braking and even try to use cruise control whenever possible, it will surely save gas.

While returning from office daily, if you always get stuck in traffic on a particular time, then try to do near your work until the traffic dies down, rather than trying to fight your way through and wasting your gas.

Tune up your car regularly, as good maintenance of your car will increase the mileage and save gas. Also try to change the oil regularly. Using a synthetic oil instead of mineral oil, because doing so will help your engine to run better and will help you to save more gas.

You may also consider the option of upgrading your air filter. More efficient brands of air filters cost a little more, but most certainly help you to save a lot of gas. Clean them regularly as well, because clogged air filter causes engine to work overtime wasting more gas.

Perform a complete fuel system treatment occasionally. Not only will it boost your gas mileage, but also result in betterment of your car’s overall performance. Faulty injectors vaporize gas poorly, burning it incompletely, so avoid them to save your gas

Save ElectricitySaving electricity is not only a matter of money that you pay for your electricity bill there are rather issues related to the amount of resources that are used to create the electricity. The researches have projected that in the next 20 years even with diligent conservation of energy, the world will need one third more electricity than it currently is using.
A great aspect that can help you to save electricity is to look at the design of your home. If you live in an older home that was built long time back, it may be worthwhile to consult an electrical contractor to find out whether or not your electrical wiring is up to code and functioning at its optimum best. Although implementing these suggestions might cost you a bit right now, but in long term aspects it would definitely help you to save a fortune.
It is an astonishing fact that homes that have electrical systems that are not energy efficient, the amount of electricity wastage can add up to hundreds of kilowatts per year as well as thousands of pounds in the bills. Also surprisingly, as winter rolls around energy consumption also rises, which bad news for a house that is not energy efficient is resulting in even higher bills.
It has been noticed that many homes use a central heating system that runs on electricity. But instead of using this you can save a lot by simply using space heaters in the specific room. Most of the modern space heaters today are designed to conserve electricity and be easy to use for safe handling. Moreover, the evaporative coolers are very effective when installed correctly. The operating cost of an evaporative cooler is only a fraction of that of a refrigerated unit.
There are tiny things that make huge differences altogether and may prove very useful to save electricity. For instance remember not to leave heating or cooling appliances on when rooms are unoccupied. You may consider the option of using personal fans and ceiling fans for relief from hot weather, as these fans cost much less to run than the air conditioners.
While cooking, a microwave is very economical option for suitable functions. It is excellent for reconstituting food, so avoid using bigger electrical appliances to save the electricity. Try not to use grill-boiler plate on top of range for utensils that are not large enough to cover it. Instead of considering the option of boiling the water on a hotplate, you may rather use an electric kettle. Another thing you should ensure is that sure your door of the microwave or the oven seals properly.

Although these advices may sound quite silly, but still most of us tend do commit these tiny mistakes which result in huge wastage of precious electricity as well as many. As there are countless things that may help you to save electricity, so the best possible thing that you can do would be to try to change your habits, and change whatever you can to save electricity.

Make Bio DieselBiodiesel is produced from the combination of alcohols such as methanol with vegetable oil, animal fat, or materials such as recycled cooking grease. It is used as an additive to reduce vehicle emissions and or as a renewable fuel for diesel engines in its pure form.

There are a number of critical issues coming up, forcing the people, in fact the entire nation to consider the usage of alternative fuel sources such as Biodiesel. Problems in the gulf region have also helped the cause of adding a sense of urgency to reduce the world’s dependency on oil. Biodiesel conversion is a viable option and a very popular one which does not involve any complications and is cent percent trouble-free.

Consequently a lot of research has gone into biodiesel conversion which gave positive results. This will probably lead to more companies jumping on the biodiesel bandwagon, bringing more investments into this type of energy source. The sooner we become less dependent on oil, the better it would be for the future.

Biodiesel in pure form produces significantly less emissions than petroleum diesel and zero sulfur emissions.

Biodiesel comes from renewable plant sources, such as oils from vegetables, soy beans, or some grains which are domestically and abundantly available.

Precisely biodiesel conversion refers to the process of subjecting the plant-derived diesel to the process of trans-esterification, which performs chemical modification of ordinary vegetable oil. The conversion helps the fuel to meet high industry standards for usage in diesel engines also prevents it from solidifying at colder temperatures.

The process of biodiesel conversion greatly helps, as it highly increases the quality attributes of the crude diesel and makes it commercially usable, providing a cost effective alternative to the conventional petroleum based products and other fossil fuels.

Commercially, many a times biodiesel is sold under the same name even after mixing it with petroleum diesel in different proportions, although the biodiesel content may be as low as only 5%. Biodiesel and petroleum diesel mix extremely well and commercially available blends use labeling conventions to describe its percentage to regular diesel. The resulting combination has higher calorific value and hence provides greater efficiency when used as fuel.Bio Diesel Production

The researches are going on all over the world to minimize the cost of biodiesel conversion and hence good quality biodiesel production ultimately. This is a crucial time to start the usage of such alternatives because it’s a well known fact that at this rate, all the resources such as conventional diesel petroleum and oil would be exhausted within no time.

Moreover every one in general, understands the need for oil drilling and refining, till the option is available, but even then they are also very well aware of environmental risks of spillage and other disasters associated with it. The best possible alternative available for every one to counter the oil crisis today is usage of biodiesel which is obtained by the simple process of biodiesel conversion.

As biodiesel conversion gains greater popularity, you won’t be required to spend money for performing biodiesel conversion, but rather earn more money as savings, if biodiesel fuel provides a cheaper alternative to gasoline, revolutionizing the world.

Solar Cells Close UpA solar cell is a device that has the capability to convert solar energy into electrical energy by the phenomenon of photovoltaic effect, and hence is also often known as photovoltaic cell.
However, usually the term solar cell is commonly used in context of devices designed specifically to capture energy from sunlight, while the term photovoltaic cell is used otherwise.
One sun is a measurement equal to the solar power incident at noon on a clear summer day, signifying that in a 1000 sun system; approximately 100 watts per square centimeter are concentrated onto the cell system.
Solar Cells are categorised into three generations indicating their chronological order of prominence. Currently researches into all three generations are going on while the first generation are most highly represented in commercial production, accounting for 89% of turn over last year, second generation technologies are most likely expected to gain market share in the year 2009.
The first generation solar cells comprise of large areas, high quality and single junction devices, involving high energy and labour inputs which prevent any significant progress in reducing production costs. Theoretically having limited efficiency of about 33% they are unlikely to achieve cost parity with fossil fuel energy generation.
The Second generation solar cell materials have been developed to address energy requirements and production costs of solar cells. Although major manufacturers have inclination towards the second generation technologies, but commercialisation of these technologies has proven difficult.
Third generation solar cell technologies aim to enhance poor electrical performance of second generation thin film technologies while maintaining very low production costs. The present research is targeted at achieving conversion efficiencies of 30-60% while retaining low cost materials and manufacturing techniques.
Solar cells find wide varieties of applications. Individual cells may be utilized for powering up small devices such as electronic calculators. Assemblies of cells form solar modules, which may in turn be linked as the photovoltaic arrays.
The photovoltaic arrays usually produce a renewable form of electricity, particularly useful in situations where electrical power from the grid is unavailable such as in remote area power systems, Earth-orbiting satellites and similar applications. Photovoltaic electricity is also increasingly being deployed in grid-tied electrical systems.
Solar Panels Home
The electricity is often fed into the electricity grid using inverters in stand alone systems in order to make practical use of the solar-generated energy. A solar cell must be capable of producing electricity for at least twenty years, without a significant decrease in efficiency. Presently the dye-sensitized solar cell is considered to be the smallest solar cell.
Nano-crystalline solar cell structures make use of some of the same thin-film light absorbing materials but are overlain as an extremely thin absorber on a supporting matrix of conductive polymer or meso-porous metal oxide having a very high surface area to increase internal reflections, representing a brand new architecture for solar cells and potentially high efficiency.

Although the silicon photocells have been utilized at different places, but the technology is limited, nevertheless these powerful solar cells have a great potential.

The term green energy is used to describe sources of energy that are considered eco friendly, non-polluting and therefore may provide a remedy to the systemic effects of certain forms of pollution, and help in preventing global warming.

Alternative energy and renewable energy are terms often used interchangeably with green energy. It suggests a non-polluting, non-fossil-fuel source of energy.

The green energy includes natural energetic processes that can be harnessed with little pollution. Energy derived from the incineration of waste, geothermal energy, wind energy, small-scale hydro energy, solar energy, biomass energy, tidal energy, wave energy and many other forms of energy fall under this category.

In many countries green energy currently provides a very small amount of electricity, contributing less than 5% to the overall sources, nevertheless the popularity is increasing day by day.

Green energy consumers either obligate the utility companies to increase the amount that they purchase from the pool, or directly fund the green energy through a green energy provider.

Green energy is commonly thought of in the context of electricity, heating, and cogeneration, and is becoming increasingly available. Consumers, businesses, and organizations all over the world are now even allowed to purchase green energy in order to support further development.

Green energy certificates have been one way for consumers and businesses to support green energy. Over 35 million homes in Europe, about a million in the United States, and many others are purchasing such certificates worldwide.

In several countries, electricity retailing arrangements make it possible for consumers to purchase green electricity from either their utility or a green power provider. However, in any case, there is no way available for the consumer to check whether or not the electricity bought is green.

Some organizations have specifically classified nuclear energy as green energy, but environmental organizations indicate the problems with nuclear waste and that this energy is neither efficient nor effective in cutting carbon di-oxide emissions, excluding it from the safer forms of energy.

The solar energy is the most popular category of green energy which finds widespread use in countless items such as solar cookers, solar heater, solar cells, solar panels and many more.

However in countries where suppliers are legally obliged to purchase a proportion of their electricity from green sources, there is a danger that energy suppliers may sell such green electricity under a premium green energy tariff, rather than sourcing additional green electricity supplies

By participating in a green energy program a consumer can minimize the usage of energy sources and even promote the use of green energy. They are also making a statement to policy makers that they are willing to pay a price premium to support a noble cause.

So it is quite obvious that green energy is the best form of energy available and we must consider this to be a competitive alternative to the conventional form of energy. It will ensure a healthier, happier, safer and a better future for our forth coming generations, leaving them with sufficient natural resources. Go green, use green energy and lead a healthy and green life!

Solar CarA solar car is an electric vehicle that is powered by the solar energy obtained from solar panels on the surface of the vehicle. These solar cars are not the practical transportation devices for daily usage presently, but are primarily demonstration vehicles and engineering exercises, often sponsored by the government agencies.
Inside these solar cars the photovoltaic cells convert the sun’s energy directly into electrical energy. Solar cars use the combination of a variety of technologies typically used in the aerospace, bicycle, alternative energy and automotive industries. The design of a solar vehicle is usually severely limited by the energy input into the car as it has the batteries and receives plenty of power from the sun. Most of the solar cars ever built have been for the purpose of solar car races
Solar cars are often fitted with gauges as in case of the conventional cars. Apart from keeping the car on the road, the driver’s main priority should be to keep an eye on these gauges to spot possible problems. Cars without gauges available for the driver will almost always feature wireless telemetry. Wireless telemetry allows the driver’s team to monitor the car’s energy consumption, solar energy capture and other parameters and free the driver to concentrate on just driving.
The most important part of the solar car’s systems is its electrical system as it controls all of the power that comes into and leaves the system. The battery pack plays the same role in a solar car that a petrol tank plays in a normal car in storing power for future use.
Solar cars use a range of batteries including lead-acid batteries, nickel-metal hydride batteries and the Nickel-Cadmium batteries. Many solar racing cars have complex data acquisition systems that monitor the whole electrical system while even the most basic cars have systems that provide information on battery voltage and current to the driver.
The mechanical systems of a solar car are designed to keep friction and weight to a minimum while maintaining strength. Designers normally use titanium and composites to ensure a good strength-to-weight ratio.Gasoline-car-converted-to-run-on-solar-power
The initial solar cars were actually tricycles or quadricycles built with bicycle technology. Presently the solar cars usually have three wheels, but few have even four. Three wheelers usually have two front wheels and one rear wheel: the front wheels steer and the rear wheel follows. Four wheel vehicles are set up like normal cars or similarly to three wheeled vehicles with the two rear wheels close together.
The two most notable solar car races are the World Solar Challenge and the North American Solar Challenge, overland road rally-style competitions contested by a variety of university and corporate teams.
The popular North American Solar Challenge, previously known as the ‘American Solar Challenge’ features mostly collegiate teams racing in timed intervals in the United States and Canada. The latest North American Solar Challenge took place from June 13th to June 22nd, 2008, from Dallas, Texas to Calgary, Alberta.
A practical application for solar powered vehicles is possibly golf carts, some of which are used relatively little but spend most of their time parked in the sun. Some solar cars have also been employed for free standing or integrated sails to harness wind energy
Many countries across the world are in the quest of building better solar cars and the recent developments include a Swiss project, Solar taxi, seeking to build a road-worthy solar car featuring a trailer carrying a 6 m² sized solar array.

More fuel saving tips for increasing efficiency

Save GasIf you consider all the factor wisely, then you would realize that making a car fuel efficient isn’t simply about keeping the engine healthy as the precious fuel can be wasted by something as minor as binding rear drum brakes, incorrect tracking, under inflated tyres or an overweight tool box stashed at the bottom.

As the common tips include changing your driving style and usage of fuel saving devices, there are many other things that are not paid much attention to, resulting in wastage of precious fuel.

Starting with the cooling system, a worn out thermostat will cause the engine to take much longer to warm up than it should. There is nothing more wasteful on fuel, particularly on a cat-equipped car where the fuel mixture is deliberately set to run rich to help warm up the catalyst.

It has been noticed that on an average car, attaining about 25 mpg, it can drop as low as 12 mpg on the first few miles from a cold start up. The quicker the engine reaches operating temperature the better; if you do a lot of short runs it may even pay to blank off a small section of the radiator to aid this, although you must be sure to keep an eye on the temperature gauge.

Many a times even out of alignment steering geometry, can nick a couple of mpg as well as prematurely wear out expensive tyres. As just an innocent brush with a curb can knock the tracking out of true, it pays to have it checked annually.

The tyre selection can greatly help you in saving fuel and cutting down your costs. Special energy-saving tyres are proving increasingly popular. Michelin claim their Energy tyre is some 20 per cent freer rolling over a conventional design and thus can save up to six per cent in fuel use over 10000 miles, equating to approximately £60 a year in the pocket!

It’s quite possible that even if your tyres are in good order, under-inflation will create more drag and sap fuel. So make sure that you keep them inflated properly. Also don’t over-inflate, but you can run them at their highest recommended pressures.Save Fuel

In fact if you need new covers, you could consider opting for a slightly larger tyre, or a higher profile type to raise the gearing and help mpg. Naturally, check that they will safely fit on the rims and not foul your car’s steering, suspension or brake systems, but it’s worth a thought. You could speak to your local tyre specialist for further advice.

As you would know that the Formula One designers spend millions to shave just a few kilos off their cars to maximise performance yet motorists lug around all sorts of weighty junk in the boot. Ensure to have a clear-out and take that roof rack off, it’s not really needed!

You may also consider converting your car to run on LPG, as it can greatly cut short your expenses as well. However, it’s expensive to install and the gas tank steals a lot of luggage space. So it’s only really viable option if you cover a lot of miles and intend to keep your car for a long time.
