Bio
Diesel
The fastest way to get off grid is to completely
eliminate your electricity bill. By buying a generator
and powering it with biodiesel or water(yes, it's possible!)
you can generate the electricity needed to power your home
for $0. That frees up money for you to use to build up your
renewable energy system! You can now buy a guide that will
show you exactly how to generate your own bio-diesel. Click

What is Biodiesel?
Biodiesel is a renewable alternative fuel produced from a
wide range of vegetable oils and animal fats. Pure biodiesel
or biodiesel blended with petroleum diesel can be used to
fuel diesel vehicles, providing energy security and emissions
and safety benefits.

Facts
about Bio Diesel
Biodiesel can be made from new or used vegetable
oils and animal fats, which are nontoxic, biodegradable, and
renewable. Fats and oils are chemically reacted with an alcohol
(methanol is most commonly used in the United States) to produce
chemical compounds known as fatty acid methyl esters. Biodiesel
is the name given to these esters when they are intended for
use as fuel. Glycerin (used in pharmaceuticals and cosmetics,
among other markets) is produced as a co-product.
Biodiesel can be produced using a variety
of esterification technologies. The oils and fats are filtered
and preprocessed to remove water and contaminants. If free
fatty acids are present, they can be removed or transformed
into biodiesel using special pretreatment technologies. The
pretreated oils and fats are then mixed with an alcohol (usually
methanol) and a catalyst (usually sodium hydroxide). The oil
molecules (triglycerides) are broken apart and reformed into
methyl esters and glycerin, which are then separated from
each other and purified.
