how do you make the fuel? do you work specifically with one restaurant? i'm curious to see how you go about doing that, that definitely sounds intriguing and green!
Our grease comes from our friend's sushi restaurant so it's all from tempura which is really clean and clear. True it doesn't do a great job in winter when it's cold, there's a slight mod for a fuel warmer but it doesn't do well when it's cold and needs time to warm up-usually it's half diesel and half bio then.
Some history of biofuels.. from
http://www.arborbiofuels.com/bio_history.htmlIn 1898, when Rudolph Diesel first demonstrated his compression ignition engine at the World's Exhibition in Paris, he used peanut oil - the original biodiesel. Diesel believed biomass fuel to be viable alternative to the resource consuming steam engine. Vegetable oils were used in diesel engines until the 1920's when an alteration was made to the engine, enabling it to use a residue of petroleum - what is now known as diesel #2.
Diesel was not the only inventor to believe that biomass fuels would be the mainstay of the transportation industry. Henry Ford designed his automobiles, beginning with the 1908 Model T, to use ethanol. Ford was so convinced that renewable resources were the key to the success of his automobiles that he built a plant to make ethanol in the Midwest and formed a partnership with Standard Oil to sell it in their distributing stations. During the 1920's, this biofuel was 25% of Standard Oil's sales in that area. With the growth of the petroleum industry Standard Oil cast its future with fossil fuels. Ford continued to promote the use of ethanol through the 1930's. The petroleum industry undercut the biofuel sales and by 1940 the plant was closed due to the low prices of petroleum.
Despite the fact that men such as Henry Ford, Rudolph Diesel, and subsequent manufacturers of diesel engines saw the future of renewable resource fuels, a political and economic struggle doomed the industry. Manufacturing industrialists made modifications to the diesel engines so they could take advantage of the extremely low prices of the residual, low-grade fuel now offered by the petroleum industry. The petroleum companies wanted control of the fuel supplies in the United States and, despite the benefits of biomass fuel verses the fossil fuels, they moved ahead to eliminate all competition.
