Which is the best hybrid car ever made so far? Who can point to a hybrid vehicle and say this is the best hybrid car? Well, if you really want compare unique car features, let me tell you this is something specialists can aim at. Just think about the competition in the car industry. Each and every car maker has one important goal in their range of activity, namely to create better green vehicles, and hopefully the best hybrid car.

Several factors indicate the candidates for the title of “best hybrid car” but with an ever changing market, chances are that the first position will not always be occupied by the same model. The efficiency to get a better consume, more horsepower, a reduced price, an improved design and great utilities remain only some of the elements to judge and appreciate a hybrid vehicle.

The concern for the fuel consume efficiency of the best hybrid car is justified given the ever increasing oil price and the burden put on the environment by toxic emissions. Well a hybrid car first and foremost aims at reducing fuel consume. Hence the best hybrid car, from this perspective at least, should be running more on electric power than on gas, and even when the regular engine is in full swing, the average gas need must remain below that of a regular car.

Regardless of the combination of battery and engine, the best hybrid car needs to achieve a gas consume that makes the initial investment worth making. Some of the best hybrid car materializations, in this line of thought, are Toyota Prius and Honda Civic, that have systems with high fuel economy rates thanks to the contribution of the electric motor.

When making classifications of the best hybrid car models size also sets them apart. Thus, you might like to know that the best hybrid car in the small, town-use category, or maybe the mid-size hybrid sedans are more suitable for your needs. Luxury hybrid vehicles are rather pretentious and expensive, but they do have their targeted buyers.

The best hybrid car according to personal requirements should be chosen by asking an expert for advice and guidance in this field of green-oriented vehicles. Thus, you should consider the cost of replacing certain equipment items, governmental tax credits, fuel economy, warranty, battery charging system and so on. Clarifications are necessary for other technical features, but that is the expert’s call.

Thin Film Solar Panels are made up of a lightweight and flexible material which can be rolled up and easily transported. Thus, they are very useful as a source of portable solar power.

The following are some basic facts about Thin Film Solar Panels:

Any person who has ever used a solar-powered calculator has had “hands on” experience with Thin Film Photovoltaics. This technology has been with us for years, creating the solar cell strips which are used to power calculators

Thin film technology has now evolved to a point where we can mass-produce solar panels, through the use of machines not unlike printing presses.

The substance used to “print” thin film solar panels is called solar ink.

Solar ink can be made in any color. In fact, it is possible to design the inks in such a way as to make use of different parts of the light spectrum.

Solar presses print thin film solar panels called solar rolls. A solar roll is 13 inches wide and can be up to 2400 feet long.

A solar roll can be cut to the required size after the solar ink has been printed onto it.

The electrical connections in a solar roll are automatically welded in by laser. This takes away a lot of the time which is required to construct our “conventional” solar panels.

Once solar technology reaches a cost effectiveness, of $1.00 per watt, its prices will be competitive with conventional fossil fuels. TFPV is rapidly approaching this benchmark and could possibly beat this in the near future.

Solar ink can be printed onto fabrics, plastics and metals, allowing one to design solar panels for a wide range of products, each tailored to their specific needs.

Thin film photo voltaic solar panels are not as effective as solid solar panels. It’s the fact that it is so much cheaper and lighter than conventional solar panels, that gives it the “edge”.

The U.S. military is extremely interested in the development of thin-film technology, and spent 1.7 million dollars at one laboratory last year in order to facilitate the development of thin film photovoltaics. It’s interested in using thin film photovoltaics for troop communication devices and to reduce the heat signatures when troops using conventional generators.

Solar shades and tents are now available, using thin film photovoltaics, that provide up to 2kw of power. This allows them to operate laptops, communication devices, TVs and much more.

Thin film photovoltaic devices are now widely available on the consumer market. A good example of this is the flexible Brunton Solarroll which comes in several sizes.

A thin film flexible solar panel weighing less than a pound is capable of recharging a laptop. Due to its flexibility, it can be rolled up and transported easily.

Thin film photovoltaics are also a realistic source of emergency power. This makes them a handy and economic addition to emergency preparedness kits and wilderness survival kits.

Current research on thin film photovoltaics is aimed at increasing the power output of thin film solar panels, should it achieve this goal there is a very good possibility that we will have solved the problem cheap clean renewable energy.

It will be very valuable if people have better understanding about “what is solar energy“. It may help lot of people to find a new way to overcome the problem of fuel energy scarcity. What’s more, let’s find the answer of “what is solar energy” in this article.

In fact, solar energy is the sun’s power exploitation. That is the first answer for the question of “what is solar energy”. It can either be used instantly or stored in cells for later use. Web can utilize solar energy in three different ways: solar photovoltaic (PV), active solar energy, and passive solar energy.

What is Passive Solar Energy?

Passive solar energy applies the position and orientation of rooms to get the most out of the sun’s warming effect on the room. It also uses effective insulation and air-tight construction to lessen heat loss from solar-warmed rooms. The use of passive solar can be done with very little time or money. In real fact, new homes being built today are built with these principles because they assist save energy costs.

What is Active Solar Energy?

The alteration of solar energy into high temperature is engaged in the active solar energy. It is used to heat the water and the air in your home. You can heat the air by applying the solar energy then distribute it by using pumps and fans. At the present times, you can find that several homes all over the world already use solar energy to warmth the water in their homes.

What is PV Solar Energy?

Photovoltaic (PV) solar energy utilizes sunlight to convert the energy of the sun into useable electricity. While PV cells do not entail direct sunlight, the charge will be larger when the light is stronger. This is the kind of energy that is being used when you see the large collection panels on top of a building.

Lots of small electronics have already used PV energy such as calculators and outdoor lights. It is increasingly being used to supply power to houses that may not have access to the power grid. For owner who want to turn to clean, renewable energy rather than using the existing power grid, panels are becoming easier to find and less costly to install.

What is Solar Energy’s Future?

To answer the question “what is solar energy’s future”, it requires us to think about the condition of energy at present times. Some experts predict that solar energy will become one of the major option energies that we utilize to power our lives. We have known that the cost of solar energy is costly but some experts predict that it will alter in nearly time. Then many people will choose to shift to the renewable and cleanest energy sources for their life.

Are you still at sea of knowing more about what is solar energy actually? Just look around your best answer herein!

What are thin film solar panels, and what could possibly be so exciting about them?

Thin film solar panels operate in the same manner that regular solar panels do, the only difference being that they are a lot thinner and require far less materials and energy for construction.

This might not sound extremely spectacular, but in fact it is. It’s a major breakthrough in solar technology.

Why are Thin Film Solar Panels so Important?

The reason thin film solar technology is considered to be such a major breakthrough is because, until now, the two barriers that have prevented solar energy and solar technology from becoming mainstream energy providers have been the 1. the cost to produce them, and 2. the problems in mass-producing them rapidly.

Both of these problems have been solved. This paves the way for rapid expansion of clean energy in the form of solar power.

What is Thin Film Solar Technology?

Thin film solar technology is a method of putting extremely thin films of photovoltaic material on to a thin layer of backing for support.

This is made possible through new inventions, such as Solar Ink. A photovoltaic material is dissolved into a solution, that is then printable as ink. It is then printed out, similarly to how books are printed.

Because of the invention of solar ink, it is possible to print photovoltaic material onto thin layers of plastic fabric or metal. This printing process is extremely fast, and thus it allows you to mass-produce solar panels at a high speed and at only a fraction of the cost.

Whereas, in the past, solar panels were bulky and weighed a serious amount, thin film solar panels weigh almost nothing and take up almost no space. This means that solar panels can now be produced at only 5 percent of the cost, as compared to our old bulky solar panels.

Uses of Thin Film Technology

The new possibility of literally printing solar panels onto materials such as fabric, plastic and metal, has opened up new doors in the application of solar power.

Some of the uses now possible are as follows:

• Military, Police and Emergency Services:
• AA battery solar charger
• Water purification systems
• Remote sensors and data transmitters
• Cell phone chargers
• Highway/transportation lighting and signals
• Foldable solar chargers
• RVs Campers Boats GPS devices
• Communications systems
• Handheld game chargers
• Medical refrigeration systems
• Metal roofing Membrane roofing Architectural fabric
• Weather stations
• Water pumping systems
• Sol laptop chargers

The above are just some of the ways that solar power can be and is being used, with the advent of thin film solar panels. I am sure that many more uses will be added, now that the price and manufacturing barrier of solar power have been broken.

1. RSS Feeds

Most blogging software such as Wordpress come with a built in RSS feed, which is the equivalent to having a newsletter subscription service, but of course is 100% free and requires no details to be passed over from the subscriber. Most people just let their RSS feed sit there on their new blogs but what you must do is submit your RSS feed URL to as many RSS directories as possible. Therefore, when you post new content on your blog, this is syndicated to your RSS feed and the directories display your most recent posts. This is one of the easiest ways to get immediate exposure every time you post content.

2. Blog commenting

If you’re looking for targeted traffic and some solid one way backlinks to boost your search engine listings, then try commenting on other people’s blogs leaving a link back to your website. Providing you post relevant and useful content/comments on other people’s blogs, the blog owner will "approve" your comments and you link will then become live. This can bring direct traffic and of course help with your rankings in the search engines. Find out about Blogging Guides – Blogging to the bank

3. Guest Bloggers

There are many advantages to having guest bloggers post their content on your site. Apart from the credibility of your blog going way up (depending on who the guest actually is), you are forming a mini joint venture where the guest is likely to tell his/her own audience about the material on your site, plus you may be able to work out a deal where you can return the favor and get access to their blog audience by appearing as a guest writer on their blog.

4. Trackback links

A trackback is when one blog communicates with another to inform the bloggers that their material has been referenced on someone else’s post. So if you were to write a really good post, I could write about your post and create a trackback on your blog that tells the readers I’ve been talking about you and your post. Not only can this bring direct traffic, but also provides another backlink to your blog which is great for a little SEO boost. When would this be most effective? Probably when I have a contrasting opinion to your original post or if I have something helpful (or controversial) to add to the original post.

Commercial wind turbines are being manufactured and installed world-wide by the main industrialized countries as a part of an international drive to both reduce atmospheric pollution, which causes climate change, and due to consideration of the depletion of oil and gas stocks and their increasing cost.

In 2008 worldwide there was approximately 94,000 MW of wind energy capacity. Of this, 60% is located in Europe, 18% in USA, and with the remainder of 22% in the rest of the world.

The largest national capacity is in Germany at present, but the Germans are likely to be overtaken by new capacity due to come online in the United States during late 2008.

The current contribution to electricity (2008) of all sources of green wind power is approximately 5% now, and achieving the 2010 target looks unlikely under current conditions.

However, many governments worldwide are reacting to high oil and gas prices to reduce national dependency on oil & gas and we can expect that renewable energy sources or “alternative” sources, as they are often termed in the US, to be strongly encouraged by most governments which do not hold their own large natural reserves of oil and gas.

The present EU policy is to require member states to contribute to 20% of all European Union (EU) energy by 2020. Within this a UK contribution of 15% of all energy by 2020 would require approximately 35-40% of electricity to come from renewable energy sources. With wind energy as the primary source envisaged to realize this commitment you can begin to imagine the huge scale of the wind energy market in the years to come.

Overall, approximately 2,500 MW of operational operational wind capacity exists at present in the UK, spread across 170 projects.

The largest wind farm today is Horns Rev, Denmark, 160MW (2002).

An example of a UK offshore project operational is the Burbo Bank Farm, off Merseyside with 25 No. turbines.

In the first round of sites the allocation resulted in 18 licenses issued for projects around the UK of up to 100MW each. Fifteen sites were awarded (7,169 MW) but none had started construction at mid 2008, due to constraints of MoD due to radar, financial variability in current markets, grid and distribution capacity provisions, etc. This is really not a large amount of capacity when one considers the number of turbines needed if the UK is going to meet the target for renewable that the EU ministers have set themselves

Just compare the above at less than 10,000MW against the capacity target which the UK Government announced in December 2007 and again in June 2008 adding up to a strategic assessed requirement for an offshore wind power resource of nearly 35 GW (35,000 MW) of offshore wind capacity to come close to fulfilling the EU’s 2020 target for renewable energy.

The UK is well blessed with high offshire winds, other major offshore players in Europe with windy shores include Denmark, which is well advanced in wind turbine installation.

Turbines used in wind turbine power projects will continue to get larger on average with sizes for recent installations on land typically having a 70 - 90m rotor diameter, with a generating capacity of up to 3 MW. Turbine sizes for the proposed offshore wind farms are likely to be 80 to 100m diameter (currently up to 126m) with a generating capacity of at least 3MW, possibly from 5 to 7.5 MW rating.

Just how important to the economics the windiness of a location is can be realised when we tell you that wind energy produced by a rotor blade involves a cube law whereby a 10% increase in wind speed yields a 30% increase in energy available from the turbine.

There is still some debate about the technology predominantly to be used. At one time vertical axis turbines looked like being evolved into very large versions. However, although a few small prototype vertical axis machines remain under development, and these designs are of course being used at a micro windpower scale, the normal consensus is that the technology was tested in 1980/90’s and has lost out to the familiar “traditional” horizontal axis designs.

Let’s admit that hydrogen gas fuel is becoming a real hit in the news and minds of people.

What is the reason for this massive love and attention trend? This has a very simple explanation. The point is that hydrogen is an element that exists in abundance all over the earth. Thanks to its abundance, hydrogen can be converted into hydrogen gas fuel for many of the same uses as fossil fuels. Without having their disadvantages.

Moreover, one should also take into account that hydrogen gas fuel in its purest form must be obtained by the separation of the hydrogen’s chemical bond to those elements. When hydrogen gas fuel is blended with pure oxygen and ignited the only resulting emissions are heat and water, you can’t get much greener than that! And this is also very important for the world of today.

Each method of distilling the hydrogen to it purest form has its own unique set of pros and cons, from emissions generated by the refining process to finding the most cost effective method of producing hydrogen gas fuel. Currently, steam methane reforming is the most popular method in the United States. This method separates hydrogen from natural gas by heating the natural gas at various temperatures.

When building hydrogen production facilities, location is a major concern. However, as a long term project they are worth it under the electrolysis method, as no harmful greenhouse gas emissions are produced. New infrastructure would almost certainly be required if the level of hydrogen gas fuel needed to satisfy mainstream demand. The use of electricity generated through means such as wind power or solar panels could allow us to employ electrolysis (the process of passing an electrical current through water via an ionic transfer device), a technology that we are already utilizing in a more cost-efficient and environmentally responsible manner.

Hydrogen is very flexible and suitable as fuel since it can be stored and easily transported in the form of gas or liquid. Hydrogen fuel can be transported in vapor form from its refinery site to up to a distance of 200 miles. For longer distances up to 1000 miles, hydrogen is transported in super-insulated tanks in liquid form.

Hydrogen gas fuel has the greatest energy to weight ratio of all known and commercially available fuels. When compared to gasoline, hydrogen gas fuel produces roughly three times the amount of energy we obtain from gasoline and over six times the amount of energy we obtain from coal.

Hydrogen gas has much better and more efficient combustion through a larger range of air fuel mixtures than gasoline. Hydrogen gas fuel has an octane rating of 130 and this is higher than the highest octane gasoline available at present at the gas station.

Hydrogen gas fuel could help us power nearly anything - from large cities to cellular phones, moped to rocket ships while still being eco-friendly. Transport vehicles can be designed to run on hydrogen gas fuel or retrofitted to be able to use it. As gasoline prices continue to rise, we will soon see if hydrogen gas fuel will be a workable replacement for gasoline.

A solar tower is a device that converts solar thermal energy (heat from the sun) into electricity. Solar towers are suitable for large-scale power generation.

The Basic Component Parts of a Solar Tower Energy Plant

* Solar Tower - The solar tower is simply a large structure with a boiler (a tank used to heat liquids) at the top. The boiler collects the heat from the sun. It is also referred to as the “central tower” or “power tower”.

* Heliostats - These are movable mirrors that track the sun and reflect the sunlight at the top of the solar tower where the heat is collected. These mirrors move as the sun moves, so as to continuously reflect maximum sunlight toward the tower.

* Heat Transfer Fluid - The reason we use the term “heat transfer fluid” is because not all solar towers use the same. Early solar towers used water to collect the heat from the sun. Some of the newer solar towers use liquid sodium. Whichever liquid is used, it is referred to as “heat transfer fluid.”

* Heat Storage - Because we still want to generate energy at night after the sun is gone, newer solar towers have methods of storing heat so that it can be used during the night to continue generating electricity.

* Steam Generator - As stated earlier, liquid sodium is now used to collect the heat, and the liquid sodium is then used to generate steam.

* Steam Turbine - A steam turbine is a generator that uses steam to generate electrical power. This is the same set-up as is used in a conventional power plant.

How Does a Solar Tower Work?

Computer controlled mirrors called heliostats track the sun, adjusting their position as the sun moves, and reflect sunlight toward the top of the solar tower, where a heat collector tank is located. Of course, more than one heliostat is needed, so an arrangement of hundreds or even thousands of heliostats is used.

The combined reflected sunlight of these heliostats is capable of producing temperatures as high as 550 degrees, Celsius at the focus point.

The liquid inside the boiler is thus rapidly heated and then pumped downward into storage tanks, or directly into to a heat exchanger where it is used to make steam.

The steam produced by the heat exchanger is then led through a steam turbine, which uses the steam to generate electricity.

As an interesting note, liquid sodium is used as a heat transfer/storage liquid, due to its ability to hold and store heat efficiently. Large storage tanks can be used to hold the heated liquid sodium. The stored “heat” can then be used at night, so as to continue generating steam which is used to generate electricity.

Currently, there are two solar towers in operation using the above design. The 64 MW Nevada Solar One and 11 MW PS10 solar power tower in Spain.

Solar tower energy is categorized as CSP (concentrated solar power) technology. There are several other power plant designs which use concentrated solar power technology. This includes the parabolic trough and the solar dish engine.

A “solar cell” is a device which changes sunlight into electricity. More technically, a solar cell is also referred to as a “photovoltaic cell.”

The term “photo” derives from the Greek word for “light,” and the term “voltaic” comes from the word “volt” which means “electrical force.” A “cell” is a small receptacle or container containing electrodes which generate power.

Thus, a photovoltaic cell is a container that creates electric force, through light.

Whereas a solar cell can generate electricity from any light source, its intended use is the collection of solar energy from the sun.

How a Solar Cell Works

The solar cell works as follows:

Photons (which are particles of light in sun rays) hit the surface of the solar cell and are absorbed a semiconductor, such as silicon.

These photons (bits of sunlight) knock electrons loose from the atoms inside the semiconductor. The photons then push the electrons along, leaving a “gap” in the atom. Another electron is then pulled from an adjacent atom to fill the gap. And so an electrical flow is generated.

The simplicity of this is that one atom has an extra electron, and the other atom is missing one. This is referred to as a “difference in potential.” Nature, wanting to remain balanced, tries to even things out by pulling another electron from the neighboring atom.

A solar panel is made up of a group of solar cells linked together to produce the desired amount of electrical energy.

A group of solar cells linked together can also be referred to as a “module.” Thus the terms “solar panel,” and “solar module,” are synonymous to each other, and essentially mean the exact same thing. “Solar panel” is the more common term, and “solar module” is the technical term.

One can use Solar Panels individually or one can link several together in order to generate more electricity. When a group of solar panels are linked together, it is called a “solar array”. The more solar panels are included in a solar array, the more power they produce.

Solar Power is a clean energy source which is virtually unlimited. I say “virtually unlimited” because the sun itself won’t last forever. But we won’t have to worry about that for the next few billion years.

Since solar power is a clean energy source which has been around for decades, one might wonder why its not used more. The answer to this lies partially in the cost of producing solar panels, as well as in the efficiency of the solar panels.

We are currently in the second generation of solar panel technology and verging on the third. A lot has changed since the first generation. Solar panels a are becoming a viable source of clean energy.

The first solar cells were relatively large and bulky compared to our current models. In view of the amount of energy and material required to produce them, and the amount of energy they actually produced, it was more costly to use solar energy than to use fossil fuels. The only exception was in places where no fossil fuels were available, such as in space.

With the second-generation solar cells, we attempted to tackle this exact problem. We attempted improve manufacturing techniques so as to reduce the costs, materials and energy needed for the production of solar cells.

Recently, major advances have been made in the production of solar cells, which have reduced production costs.

One contribution in this area was the development of techniques to coat glass or ceramic materials with very thin layers of semi-conductive substances. This made it possible to produce solar panels using only a fraction of the semi-conductive material that was required earlier. The production of solar panels using this second-generation technology is referred to as “Thin Film Technology.” (For more information see Solar Ink.)

Third-generation solar energy technologies are currently being researched and developed. The objective is to improve the power of solar cells even further (while keeping production costs to a minimum) in which case thirty to sixty percent of the sunlight hitting the panels will be converted into electricity. (Current solar panels only convert about twenty percent.)

But regardless of third generation solar technology, the second-generation solar cell is efficient enough to make solar technology viable - and a host of new solar-powered products have hit the consumer market.

Solar-powered calculators have been around for a while now, we’ve all seen them. We have even seen a few other novelty devices. But only in the last few years have solar devices come into serious and practical use.

The last two years in particular have seen a virtual explosion of solar devices hitting the market. Solar flashlights (I’ve often wandered what use they were), solar-powered radios, and, recently, solar battery chargers.

One can also now find a wide range of portable solar chargers and panels, which are lightweight and easy to transport, yet capable of providing a decent amount of power in even the most remote locations. Solar chargers are becoming a standard part of emergency preparedness kits and wilderness survival kits.

All of this is a result of the developments in solar cell technology, and the coming of the Solar Age.

Hydrogen for cars - how to run your car on water.

As gas prices are rising to previously unimaginable levels, every available resource is being explored to replace fossil fuel by official energy commissions as well as by the general public. Hydrogen fuel seems to be a possible alternative. Hydrogen for cars will not only provide the chance to explore new energy sources; it will also open up better potential for us to improve how we travel overall.

The era of hydrogen fuel car?

Hydrogen gas keeps climbing the list as one of the top contenders for fossil fuel replacement. It exists naturally in everything from coal and water to the compost heap in your backyard.

Methods for producing hydrogen fuel for cars can vary, but they are all quite efficient and much cleaner than is fossil fuel production. A gasoline production refinery requires 300 billion gallons of water to produce that fuel, but if it produced the same amount of hydrogen, it would only need one million gallons of water.

A gallon of hydrogen for cars costs half the price of a gallon of gasoline and improves fuel economy by more than two thirds. Hydrogen fuel generates lower engine operating temperature and there is no emission of hazardous fumes by its use.

A big problem hindering the production of hydrogen-fueled vehicles is the lack of available hydrogen fuel. In the future, home hydrogen refueling stations may become a realistic possibility, but they are not currently affordable for most people.

An explosion of new vehicle designs will emerge when hydrogen fuel powered cars become the standard in the automobile industry. The electricity to power these vehicles would be generated within a much smaller engine from the hydrogen fuel, thereby eliminating many of the limitations imposed not only by the size of gasoline engines, but also those restrictions based on the heat produced by a gasoline engine. Limitations from designing around current driveline equipment would also be eliminated by the new hydrogen-fueled vehicles.

Clean, cost effective and environmentally safe, hydrogen is the fuel of our future. As hydrogen production increases and becomes more available, fueling stations will open and we will reap the savings and environmental benefits of using hydrogen for cars.
