Taking a close look at a typical BioDiesel molecule represented by a Fatty Acid Methyl Ester (FAME) structure, where R stands for a general oleaginous hydrocarbon section:

R-OC-O-CH₃

If the formula is rewritten using parentheses you realize how much real CO₂ is actually hiding in each molecule of FAME:

R-(OC-O)-CH₃

In the above formula there is only one useful type of carbon, meaning the hydrocarbon found in “R” and “CH₃”, while the rest is plain POLLUTING DEAD WEIGHT.

R-(OC-O)-CH₃ = R-CH₃ + CO₂

This pollutant, one whole CO₂ molecule, is already built into FAME molecules, and you are stuck with it! A typical FAME blend carries between 14 to 20% of CO₂ as ballast, all going straight into the environment without rendering returns in heat, useful work, or in mileage. A vehicle making 25 miles per gallon with petroleum diesel, with FAME makes 21 mpg. The CO₂ in FAME is practically pre-formed and has no energy value, yet it certainly pollutes the environment giving plenty of carbon redundancy.

FAME can mean buying 14 to 20% less fuel for your dollar. All the CO₂ that is released to the atmosphere, arising from energy-depleted carbon amounts to redundant emissions. By the same token, this carboxo (OC-O) part of FAME biodiesel should not be taken into account when figuring CARBON CREDITS.

Redundant emissions result from a lesser efficient fuel, which promotes more production of FAME.

More production of FAME requires more use of fossil methanol. With increased generation of non-fuel side products, additional purification procedures are required and increase the risk of additional pollution. In other words, carbon credits should not be given to any energy-depleted carbon. Carbon credits should not take redundant emissions into account.

In FAME the dead weight should be subtracted, and carbon credit adjusted so that benefit is given only to those carbons contributing to the true heat value of the BioFuel.

As opposed to FAME, which contains ester structures bearing the carboxo (OC-O) group, HEBD are fuels derived from HEBF Technology, which do not involve any esters or energy-depleting oxygen groups. HEBD is a fuel involving energy-rich compounds, characterized by the nitrile functionality, represented by the following structure:

R-CN

This fact has been proven through calorimetric studies, where HEBD competes at the same energy levels as commercial petroleum fuels.

This is sample text describing the linkblog entry. In most cases however, you'll want to leave this blank, providing just a Title and an Url for your linkblog entries (favorite/related sites).

b2evolution uses old-style permalinks and feedback links by default. This is to ensure maximum compatibility with various webserver configurations.

Nethertheless, once you feel comfortable with b2evolution, you should try activating clean permalinks in the Settings screen… (check ‘Use extra-path info’)

In the /blogs folder as well as in /blogs/admin there are two files called [sample.htaccess]. You should try renaming those to [.htaccess].

This will optimize the way b2evolution is handled by the webserver (if you are using Apache). These files are not active by default because a few hosts would display an error right away when you try to use them. If this happens to you when you rename the files, just remove them and you’ll be fine.

By default, b2evolution blogs are displayed using a default skin.

Readers can choose a new skin by using the skin switcher integrated in most skins.

You can change the default skin used for any blog by editing the blog parameters in the admin interface. You can also force the use of the default skin for everyone.

Otherwise, you can restrict available skins by deleting some of them from the /blogs/skins folder. You can also create new skins by duplicating, renaming and customizing any existing skin folder.

To start customizing a skin, open its ‘_main.php‘ file in an editor and read the comments in there. And, of course, read the manual on evoSkins!

By default, all pre-installed blogs are displayed using a skin. (More on skins in another post.)

That means, blogs are accessed through ‘index.php‘, which loads default parameters from the database and then passes on the display job to a skin.

Alternatively, if you don’t want to use the default DB parameters and want to, say, force a skin, a category or a specific linkblog, you can create a stub file like the provided ‘a_stub.php‘ and call your blog through this stub instead of index.php .

Finally, if you need to do some very specific customizations to your blog, you may use plain templates instead of skins. In this case, call your blog through a full template, like the provided ‘a_noskin.php‘.

You will find more information in the stub/template files themselves. Open them in a text editor and read the comments in there.

Either way, make sure you go to the blogs admin and set the correct access method for your blog. When using a stub or a template, you must also set its filename in the ‘Stub name’ field. Otherwise, the permalinks will not function properly.

By default, b2evolution comes with 4 blogs, named ‘Blog All’, ‘Blog A’, ‘Blog B’ and ‘Linkblog’.

Some of these blogs have a special role. Read about it on the corresponding page.

You can create additional blogs or delete unwanted blogs from the blogs admin.
