Biofuel
Biofuels are a source of energy derived from living organisms that have not been extracted from sequestered reserves in the earth and whose natural emissions have a neutral impact on the environment.

How do you make Bio-diesel fuel?
It is made by taking vegetable oil and mixing it with an alcohol eg. methanol, and a catalyst, usually potassium hydroxide [cuastic soda] at a temperature of 140F or 55 deg C to cause a chain reaction known as transerification, whereby the free fatty acids are made into esters. The byproduct is a crude form of glycerine that can be cleaned up and made into soap etc, or composted. The process can can also be done using waste veg oil and therefor helps with waste recycling. The resulting biofuel gives off far less emissions than mineral fuel and is classed as Co2 neutral, as it only gives off the same amount of Co2 as the plant took in while in growth. The fuel can be used in most diesel vehicles without modification, and mixes readily with conventional fuel. Power and mileage are little different, but its lubricity is far greater than low sulpher diesel, and it is used by many countries at a level of about 5% in forecourt fuel to help with lubrication and the environment. UK will have 2.5% in2008 and 5% added in 2009. Production costs mean it is only slightly cheaper than mineral diesel at the pumps, but with care and understanding it can be produced in your workshop for private use. the cost of this is considerably less. In the UK you can currently produce up to 2500 litres a year for your own use without having to pay road fuel duty. There is a Yahoo group that dry washes that makes it a lot easier. http://tech.groups.yahoo.com/group/biodieselhouston
Is biodiesel and biofuel the same?
Biodiesel is one kind of biofuel. There are other kinds of biofuels too.
What is the definition of non-mechanical energy?
energy that is produced by non-mechanical means, meaning nothing to do with machines.
it is a device that consisting of immobilized layer of biological materials like enzymes,antibody,hormone,nucleic acid,organelles or a whole cell and its contacts with a sensor. The sensor converts the biological signals into electrical signals. It is used medicine and industry.
For example:blood glucose level can be detected using biosensor
Yes it is , mainly comes from methane gas also known as farts
What are the pros and cons of bio diesel?
Bio diesel is fuel that will run a diesel engine that is made from used oil or fat usually from deep fryers or even liposuction. pros are that is is cheap to make ( most resturants will gladly give it away), and it burns clean ( except for the smell of french fries), and you are recycling something that is normally disposed of ( very un-green). The only cons that I can think of are the amount of time it takes to refine it, and the space it takes up. Glycerine is the only real by-product and even that can be further refined into soap.

AnswerBio diesel and cold weather dont get along. Below freezing temperatures are very risky because bio diesel will freeze in your car and then your stranded in the cold. It is not fun changing fuel filters in -10 deg F. weather, trust me on that one.

1853 by scientists, E. Duffy and J. Patrick, conducted the first transesterification of a vegetable oil, many years before the first diesel engine became fully functional.
What plants are used for making Bio fuel?
Any plant that produces fat can be used to produce biofuel. The most common plants used are the oil seed plants such as corn, rape, sunflour soybean, palm etc.
What is the mpg of a biodiesel Ford f-250?
The only biodiesel capable Ford engine is the new 2011 6.7L Powerstroke Turbo Diesel V8. With conservative driving, people have achieved 28mpg highway and 21mpg city. If you drive unconservatively and normal, you're looking at 21mpg highway and 16mpg city. Ford has really stepped it up. They are killing the competition now days.
How did bio fuel affect food supply?
More farmers started to make bio fuel crops rather than food crops. The bio fuel crops take resources such as land and water away from food crop production, which means that food crop prices may rise as demand rises.
What is the future of biodiesel?
Biodiesel has big potentials as alternative fuel such as eolic and sun energy.
A big obstacle for biodiesel is land productivity of actual plantations of vegetable oils.
Palm oil gives the best productivity but it is far too little to cover whole world population needs.
There are researches in algae oil production because algaes has an enormous productivity (per occupation of land) but production costs are far too high.
The history is a little vague; but the two prominent people who first "discovered" and applied bio-diesel were George Washington Carver and Rudolf Diesel.
Rudolf Diesel was the creator of the Diesel Engine and he ideally envisioned the diesel engine being used with a bio-fuel source. On a side note, he actually presented a diesel engine running on peanut oil in the Paris Exhibition in 1889.
George Washington Carver worked with Henry Ford to create a bio-diesel engine; however, at the time petrol-diesel was more easily accessible and cheaper than to produce a bio-diesel fuel source.
Where does biofuels come from?
Biofuel comes from petroleum products which come from below the ground. Ethanol, however, the "bio" part of biofuels, comes from corn.
bio kerosine is made from the catalytic cracking of bio diesel
Why are biofuels considered to be carbon neutral?
Bio fuels are considered carbon neutral because they give off the same amount of carbon when burned that they absorb while growing. So, unlike fossil fuels (coal, oil and natural gas), they don't pollute the environment by adding extra CO2 to the atmosphere.
As long as we choose to continue to grow the feedstocks involved, or until a better technology is invented.
What are two advantages of using biodiesel rather than normal diesel?
1) It is environmentally friendly
2) It is made from renewable resources
What are the advantages of switching to biodiesel equipment?
Biodiesel fuel is biodegradable, non toxic, is a renewable resource, emits less pollutants and fumes, and is economical. Because of the advantages it is easier on the environment and because it is non toxic with fewer fumes and pollutants it is safer to use around children.
