| Successful solar cookers were reported in Europe and India as early as the 18th century. The increased use of glass during that period helped inventors to trap heat & hot air. In 1870, Augustine Mouchot invented a fairly portable oven for the French Foreign Legion. It could bake a pound of bread in 45 minutes or 2 pounds of potatoes in one hour.
Around the same time, W. A. Adams developed an eight-sided mirrored oven which reflected light through a glass cone located in the center of the oven. This oven could cook a 12 pound turkey in 4 to 5 hours. This is still a popular design today. We actually use a large model, very similar to Adam’s oven. In this oven we can cook 60 pounds of food at a time |

Welcome to the wonderful world of Biodiesel. It is a fun and rewarding hobby in which you can make your own fuel to run in diesel engines. Biodiesel is most commonly made by chemically altering an organic oil through the use of a catalyst and an alcohol, typically Methanol. The chemical reaction that occurs through this process breaks down the oil molecules and replaces the glycerine portion of the molecule with an alcohol molecule. The glycerine falls to the bottom and is drained off resulting in Biodiesel. The Biodiesel is then typically washed, to remove any extra impurities and is then used as a fuel in a diesel engine without making any modifications to the engine. |

Biodiesel is known chemically as a ‘fatty acid methyl ester’. Which is just a fancy way of saying it’s a product made from Methanol and an organic oil with fatty acid chains in it. It is easily made and has many benefits, including environmentally friendlier tailpipe emissions and improved engine performance. To get started making Biodiesel, there’s a few things you need to know. |
