The history of hybrid cars is immersed in controversy. Not so much for the product itself, but for the technology it uses. Is it old like the conception of wheel itself, or is it a recent idea, as recent as the embryonic stem cell technology?
First of all, a hybrid car is a vehicle that uses on-board RESS, or rechargeable energy storage system. This is coupled with a fueled propulsion power source for the automobiles propulsion. The Hybrid car is a low-gas consuming vehicle, therefore, a low-polluting vehicle.
The last characteristic is particularly important because of the growing consciousness of people worldwide on the need to protect the environment.
History points to the clear differences between hybrid and all-electric cars. Electric cars use batteries charged by an external source. On this note, almost all hybrids, save for those considered as mild-hybrid, still need gasoline or diesel as their fuel source. Other fuels are also available in the form of ethanol or other plant based oils. Hybrid vehicles also use hydrogen gas occasionally.
What is the history of hybrid cars?
The history of hybrid cars is closely intertwined with the history of the automobile itself. In 1898, Ferdinand Porsche, a young Czechoslovakian, designed the Lohner-Porsche carriage, a series-hybrid vehicle that utilized a one-cylinder gasoline internal combustion engine. This engine spun a generator which powered four wheel-mounted electric motors.
The car was eventually presented at the 1900 World Exhibition in Paris. The said automobile, capable of up to 56 km/h (35 mph) fast destroyed several Austrian speed records. In 1901, it won the Exelberg Rally, with Porsche himself driving the car. Mass production during this time was yet to be developed, but for Porsches future-looking design, 300 units of this model were sold to the public.
The first Porsche model however, technically speaking as we know Porsch today, was a hand-built aluminum prototype, and was completed on June 8, 1948.
The development of the first transistor-based electric car in 1959, the Henney Kilowatt, heralded a new development in the history of automobiles as a whole, and the history of hybrid cars in particular. This transistor-based electric car, paved the way for the electronic speed control. Ultimately, this made the road for the development of modern hybrid electric cars possible.
The Henney Kilowatt was considered the first modern electric car. It was a product of collaborative work between the National Union Electric Company, Henney Coachworks, Renault, and the Eureka Williams Company. Whilst the sales of the Kilowatt during this time were far from encouraging, its development served as the prototype for the other automobiles down the line of hybrid cars.
Between the 1960s and 1970s, another prototype of the earlier electric-hybrid vehicle was built by Victor Wouk. Wouk is among the scientists involved with the development of the Henney Kilowatt automobile. For this work, some historians bestowed upon him the honor being the Godfather of the Hybrid hybrid car.
For his pioneering work, Wouk installed a sample electric-hybrid drivetrain into a 1972 Buick Skylark, courtesy GM for the 1970 Federal Clean Car Incentive Program. The program was later axed by the EPA in 1976. Hybrid enthusiast and supporters continued building hybrid automobiles. These models however, were not put into mass production.
In the fading years of the twentieth century however, the history of hybrid cars has taken on a new course.
1978, the regenerative-braking hybrid, was developed by Electrical Engineer David Arthurs. The said regenerative-braking is to have become the core design concept of most hybrids, currently available in the market. The first attempt of Arthurs used off-the shelf components, including an Opel GT. But the voltage controller that links to the battery motor and the DC generator belonged to Arthurs.
Fast forward in the 1990s
The history of hybrid cars took the final step to modernity in terms of mass production during the Bill Clinton administration. Clinton initiated the Partnership for a New Generation of Vehicles program in September, 1993, that involved the Department of Energy, Chrysler, Ford, General Motors, USCAR, and various governmental agencies. The partnership was tasked to engineer a modern efficient and clean vehicle.
In 2001, this program was replaced George W. Bushs own hydrogen focused FreedomCAR initiative. The focus of the FreedomCAR initiative was to fund research that is considered high risk for the private sector to engage in. The long term purpose of which is the development and production of petroleum emission.
The success of hybrid vehicles in terms of mass production however, became a reality, when the Japanese car manufacturer entered the American market. This is when the history of hybrid cars finally took its modern development. Honda Insight and Toyota Prius became the modern progenitor of modern day hybrid vehicle available today in the market.

Biodiesel Testing - Quality and Purity Testing Increase Confidence And Assure Results
By Andrew Stratton
Biodiesel and biofuel production is growing at an ever growing rate as new production facilities appear across Europe, Asia, and the Americas every month. Manufacturers of biodiesel testing equipment are responding to these growing demands to supply the market at every level.
Biodiesel and biofuel production is growing at an exponentially increasing rate as new test-bed plants and full production facilities are being approved every month across Europe, Asia, and the Americas.
At present, biofuel production is considered experimental, and compared with other fuel production techniques, the total output is still very low. Feedstock supply lines are therefore quite limited, either being sourced from widely distributed waste products of other industries, or from niche crops like canola, a relatively new rapeseed cultivar. This creates a problem for both major and minor biodiesel producers, who have the daunting task of producing homogeneous, high quality fuel sourced from feedstock of varying and ultimately unknown purity and content. The market has responded to the demands of these new industries to supply quality assurance biodiesel testing equipment for every production scale.
Given the climbing public awareness of global warming and strains on global energy output, governments and corporations around the world are fronting the expense of rebates, research grants, and tax breaks for operators in industries which work towards reducing greenhouse gas emissions, making the concept of small, high-tech niche-industry start-ups economically viable. This has attracted big investment dollars in Brazil, the United States, and some members of the EU - most notable among these being Germany, where there are dozens of medium and large-scale alternative energy generation plants.
Biodiesel is defined as a diesel equivalent produced via transesterification of common fats and oils. There are three main avenues of supply of feedstock to biodiesel production plants. The first of these is dedicated crops grown specifically for their organic oils. Examples of these include soy beans, canola (rapeseed), oil palms, and algae. Canola and soy accounts for most of the total biodiesel production feedstock for the world, as it can be grown with conventional farming techniques, with predictable results.
The crop with the potential to produce the most oil is actually a species of algae, Botryococcus braunii, however, there remain serious doubts about its viability as a crop. Medium scale ventures prefer the waste by-products of other farming methods. The woody part of corn plants, left over wood pulp, and other biomass materials can be used as a substrate for biodiesel or ethanol producing bacteria. This supply is desirable for medium-scale producers as it results from otherwise less valuable by-products that can be obtained in reasonably large quantities.
Small-scale and hobbyist biodiesel producers are most likely to make use of waste vegetable oils and animal fats from cooking and commercial food production, as these are ubiquitous, but usually available only in smaller quantities, and hobby users are not likely to need any more raw feedstock than is necessary for a tank of fuel in their car every week. Furthermore, it is impractical for larger producers to collect kitchen waste in the same way an individual can, at least until demand grows enough for such infrastructure to be built.
Large scale producers have ongoing testing requirements for samples from billions of gallons biofuel every year. Due to the experimental nature of the industry, initial investment for such projects is quite expensive, however, due to the mostly uniform content of the feedstock crops used, large biodiesel production plants have run fairly reliably once established. For big biodiesel, the emphasis is on quality assurance: There are stringent requirements put on producers to keep levels of pollutants and various contaminants under tight control. Areas tested can include alcohol content, ester content, sulfur, heavy metal, and water quotas.
Additionally, biodiesel must exhibit certain physical characteristics like viscosity and flashpoint temperature. Small and medium scale producers have slightly different challenges to overcome, as they often do not sell their product, but rather, use it internally to power on-site farming machinery, or in the case of a hobbyist, the family sedan. The challenge here is not in producing product that meets stringent sales requirements (although it is desirable), but rather, ensuring that the higher number of relatively small batches are safe and uniform, so as not to produce content that damages the engines of machinery and equipment.
While this work can be done in-house, it is far more economically viable for producers to contract out as possible. Larger testing enterprises usually have of at least one HPLC (High Pressure Liquid Chromatography) machine or Gas Chromatograph, which are available for less than US$20,000, as well as all the appropriate glassware and apparatus to conduct titrations and other analytic procedures. At the hobby end of the market are self-contained biodiesel reaction vessel kits available for less than $500, and biodiesel testing kits for testing small quantities of product which can be sourced for less than $50.
With the growing public concern over the excess of atmospheric carbon, world peak oil production, and alternative energy solutions, biodiesel is beginning to look like an increasingly appealing stepping stone in between petroleum products and a completely clean implementation of energy storage, like hydrogen. Biodiesel testing requirements factor into the equation for small, medium, and large scale producers to ensure a supply of quality product.

How Can I Benefit from BioDiesel?
By Steve Dolan
If you have an interest in being environmentally friendly, then no doubt you're aware of the damage fossil fuels are doing to our environment. Not only that, but at some point they will run out. Add in the recent jump in gas prices, and it's hardly surprising that more people are talking about making their own biodiesel fuel. Although it sounds like a great idea, you need to consider a few points before going ahead and making your own biodiesel fuel.
What Is Biodiesel?
To start with, let's take a look at what biodiesel fuel actually is. At its most simple, biodiesel fuel is made from either vegetable oil, animal fat, or mixture of the two. It's a clean burning fuel that is made from renewable resources hence the name biodiesel.
Generally, biodiesel fuel is made from straight vegetable oil, sometimes referred to as SVO. So if you want to make your own biodiesel fuel, you'll need to have an adequate supply of the basic ingredients. Unfortunately, most households don't produce enough waste animal fat or vegetable fat to come anywhere close to making enough biodiesel fuel to keep the family car running.
Using Recycled oil
This has led to a whole new industry, with the basic aim of sourcing much larger quantities of raw product. They get together with restaurants, bakeries, and any other business that uses a deep fryer, so that they can collect the used oil for recycling. The oils are then blended and used as the basis for biodiesel fuel. The processes are the same as you'd use to make biodiesel fuel at home, but by having access to a much larger supply of raw products, these companies can produce biodiesel in quantities that are more viable.
Can I make it at Home?
One thing to remember is that it's not quite this simple! Used vegetable oil needs to be mixed and stored, which can be quite a problem if you have large amounts of it. You also need to dewater, filter and deacidify the waste oil before it can be used for making biodiesel. This makes the production of biodiesel fuel at home a lot more complicated.
Having said that, it's certainly still quite possible to make biodiesel fuel at home, simply by buying straight vegetable oil, rather than using waste products. Even though it will cost you a lot more, when you compare it to the cost of buying the necessary amount of gas to run your car for a year, you can still save an enormous amount - somewhere around 75 percent. Even better, you're saving the environment too.
Can I mix it with Petroleum?
The short answer is yes! It can be blended with petroleum in any percentages and used as fuel. There is a fuel called B20 which is 20 percent biodiesel that has shown significant environmental benefits. It can be used in an existing diesel engine with either little or no modifications. The only thing to be aware of is that biodiesel acts as a solvent and can remove old deposits on on your fuel tank walls and your fuel lines. This may lead to a clogging of your filters so care should be taken. But hey - then you have a clean system!!
So if you're interested in saving money and helping out the environment, look at the option of making biodiesel fuel at home. It takes a little bit of effort, but the rewards are definitely worthwhile.

11 Most Frequently Asked Questions on Converting Your Car to Biodiesel
1. OK, So what do I need to do to convert my car to biodiesel?
First and foremost, you need to have a diesel engine car. Biodiesel CAN NOT be used in a gasoline engine. Having said that, any engine that runs on #2 diesel can also be run on biodiesel. This means, home furnaces, generators, semi-trucks, farm equipment, fishing boats, etc. There is really nothing you need to do and nothing you need to convert. Just use it the same as any other fuel. “Conversion” becomes necessary when you want to run your diesel engine on Straight Vegetable Oil (SVO) For some pre-1994 model vehicles it is said that you need to replace your rubber hoses with synthetic ones. But truthfully, unless you have a leak, I wouldn't bother.
2. How much money will I save?
It really depends on you, and how you decide to make your own biodiesel. For example, if you are using waste vegetable oil from restaurants, (free feedstock) and buying other ingredients in bulk, your savings are going to be substantial. Say, around $2.00 or more per gallon.
3. Is it true that a gradually increasing the amount of biodiesel in my diesel fuel is the best way to start using biodiesel in my vehicle?
Not necessary. There is no mechanical reason that I know of to support this. Any blend of biodiesel, from 100% biodiesel (B100) to 100% diesel can be used in any diesel engine.
4. Should I replace my fuel filter before using biodiesel?
Not necessary. Biodiesel is a solvent and as such will also start cleaning your diesel engine and your fuel system. What it is going to clean is the sludge left behind from regular diesel fuel. Over time, this sludge can clog your filters. The truth is, biodiesel will keep your car's fuel system very, very, clean. The degreaser cleaning properties of biodiesel will clean the system of the accumulated diesel sludge/debris first. It might take weeks, months or years, who knows? Engines are funny. After a while, you may need to change your fuel filter, but you'll need to change them anyway as a normal maintenance procedure. If it clogs up, or you are having a problem (loss of power, smoking, coughing, trouble starting, etc.) and you suspect it could be related to the fuel filter, then by all means, switch it out, they are fairly cheap anyway. Simply change out the filter and chances are your problems will go away. It's not a bad idea to keep an extra fuel filter on hand anyway...just in case. The good news is, once your engine's fuel system has been cleaned, it will stay incredibly clean from then on.
5. I have heard that biodiesel will eat or degrade the rubber in my fuel system?
Biodiesel is a solvent and a degreaser (a good one) and as a solvent, yes, it will eat rubber over time. The truth is, petroleum diesel with a high sulfur content does this too, only slower. Biodiesel acts a lot like Ultra Low Sulfur Diesel (ULSD) that is now fast becoming the diesel standard. Also, since 1993, diesel engines and equipment have been reworked and redesigned, using synthetic rubber with ULSD in mind. The auto makers have been phasing out rubber from the fuel systems themselves. This is resulting in fewer fuel leaks for diesel and biodiesel users alike. If you have a pre-1994 vehicle with rubber fuel hoses and are experiencing leaking problems, then yes, you should replace them with ULSD compatible hoses.
6. If I switch to biodiesel and don't like it, are there any problems with switching back to diesel again?
No problems at all. You can switch back and forth as much as you like.
7. How are automobile makers, and specifically their warranties, responding to biodiesel usage?
It's kind of interesting to watch, truthfully. As the biodiesel industry gets older and wiser, more and more OEMs (Original engine Manufactures) are warming up to this idea and making positive statement about 100% biodiesel and this is reflected in their warranties. The truth is, it's kind of tough for them to argue the fact. The diesel engine, after all, was designed for this. Caterpillar, John Deere, and New Holland all accept and explicitly warrant B100 biodiesel in their engines. Others are taking a more "wait and see" attitude. They are warranting blends like B20, or B5 but stop short of wholeheartedly endorsing the idea. Other say they "neither oppose nor endorse" the use of bio-fuels.
This is where it gets interesting; Mercedes and Volkswagen both sell cars in Europe and the USA with diesel engines and there is no problem with warranty issues in Europe, but here in the good ol USA, they don't/won't support the use of biodiesel or the biodiesel industry. So bottom line? One, check your warranty. Two, if a OEM wants to deny a warranty based on biodiesel use, they can. But legally, they have to show a compelling reason that biodiesel hurt the engine. Which would be very hard to do. This is a very good reason to use ASTM (Commercial biodiesel) fuels, especially in newer cars or trucks.
8. What is biodiesel made from, besides vegetable oil?
Because modern diesel engines have been modified to meet diesel #2 viscosity standards, straight vegetable oil like the kind Rudolf Diesel used in 1912, is much thicker. This is the thing which kept biodiesel out of the energy/fuel playing field for so long. What has happened recently is a process called "transesterification." This process is used to thin the vegetable oil and remove the glycerol molecule from the vegetable oil and replaces it with methyl alcohol , or methanol. In order to do this, the methanol is mixed with sodium or potassium hydroxide (Lye) before being mixed with the vegetable oil. This is the basic process. Commercial production requires more ingredients and more refining processes, but you get the picture.
9. Should I worry about residual methanol, lye, or glycerol?
For home-brewers, the possibility of residual ingredients or by-products in the brewed biodiesel is a compelling reason to "wash" then test the biodiesel. Biodiesel that is commercially sold, is regulated and made to the ASTM standard, does not allow for residuals to be present. Therefore, you should have little worry with commercial biodiesel .
10. I'm thinking about converting my car/truck to run on straight vegetable oil (SVO) because it does not involve all the chemicals, and is cheaper. Why doesn't everyone just convert to SVO?
As we have said, just because the first diesel engines were designed to burn vegetable oil, a lot has changed in the engine world since 1912. Biodiesel fuel, to work efficiently in a modern diesel, we need to lower the viscosity (thickness) of the vegetable oil. we accomplish this through the biodiesel production process. It can also be accomplished by modifying the engine with a SVO Conversion kit. But additionally, there are other reasons not to use straight vegetable oil. One, it still contains glycerol which doesn't burn as cleanly as biodiesel and can leave deposits behind in the injection chambers. Two, SVO still needs to be de-watered, filtered and heated prior to introducing it into your tank. Also, filtering SVO can be very tedious to say the least, needing lots of time and energy, not to mention equipment and tools
11. Will biodiesel work in kerosene heaters and/or oil furnaces?
The short answer is...yes. Biodiesel is 100% compatible with diesel #2. There are no worries in that regard. One of the compelling reasons to buy a biodiesel kit in my opinion is to get rid of that financial albatross, called "heating oil" in colder climates. A biodiesel kit can pay for itself in a matter of months, one winter definitely. Kerosene, which is also known as diesel #1, or heating oil #1, is thinner than diesel #2. This, of course, requires a bit more experimentation, but generally, if a heater is designed for kerosene, then it will work with a biodiesel blend. (meaning a higher percentage of kerosene and a lower percentage of biodiesel).
