Nature and Spiritism: BIODIESEL

Biodiesel fuel is a clean burning alternative fuel that is made from 100% renewable resources. It is considered the fuel of the future. Sometimes it is also known as Biofuel. Biodiesel does not contain petroleum, but can be mixed with petroleum to produce a biodiesel blend that can be used in a number of vehicles. Pure biodiesel fuel, though, can only be used in diesel engines. Biodiesel is biodegradable and non-toxic, making it so safe that common table salt has been proven more toxic.

Biodiesel is not like vegetable oil alternative fuels. Biodiesel can be used in its unaltered form in diesel engines. Vegetable oil fuels must be modified and used only in combustion- ignition engines. This makes biodiesel one of the easiest alternative fuels to use. In fact, it is a great option for use on farms in farm equipment.
Biodiesel fuel is made through a process called transesterfication. This process involves removing the glycerin from the vegetable oil or fat. During the process byproducts are left behind, including methyl esters and glycerin. Biodiesel is free from such substances as sulfur and aromatics which are found in traditional fuels.

Apparitions

Apparitions
An apparition is defined as the supernatural manifestation of the soul of a decease person or animal, typically referred to as a ghost. Apparitions are visual experiences. Throughout history human beings have seen ghosts. Despite research efforts there is still very little known about apparitions. They are the most compelling part of the supernatural field. The one thing that is known about apparitions is that no two are exactly alike. They are as complex and diverse as each living person. Every apparition will have it's own cause, origin and meaning. It's up to the ghost hunter to analyze the facts of each case and develop solid conclusions. To help the ghost hunter acquire a better feel for the kind of apparition they are dealing with, apparition categories have been created. You will find that most apparitions will fit into at least one of these categories or share characteristics with a couple different categories.
