During the Hurricanes there were diesel powered generators, one of which powered the electricity to a building carrying a CRT projector, without that diesel fuel, the generator would not have powered the building, which would not have powered the CRT Projector which gave images of the hurricane for the building.

Therefore, this is alternative fuels for powering diesel generators which run CRT Projectors, and not OT.

Chickens into Oil

By John Gartner, AlterNet. Posted June 8, 2004.

In the quest for renewable energy sources, anything is fair game -- even fowl. Are chickens the fuel of the future?

The spike in gas prices and the instability in the Middle East are energizing interest in oil alternatives such as biodiesel and ethanol. But one company has seized on a way to capitalize on two seemingly disparate problems: diminishing oil reserves and wasted animal carcasses. Their solution? Turn the animal carcasses into oil. Turkey and chicken waste products (guts, blood, and carcasses) that are discarded by the ton each day are now being turned into a "bio oil" fuel that can be refined as diesel or gasoline.

For decades, scientists have attempted to rapidly turn animal carcasses or other biomass solids into liquid fuel. Researchers have been refining the "pyrolysis" process of using extreme heat, pressure and a catalyst that is akin to the natural occurrence that turned dinosaurs into petroleum, according to Dr. Richard Cohen, the Graduate Studies Chairman in the Mechanical Engineering Department of Temple University.

In May, a processing plant in Carthage Missouri began turning turkey guts, feathers, blood and carcasses into an oil alternative. Renewable Energy Solutions, a joint venture between ConAgra Foods and Changing World Technologies, is each day transforming 200 tons of material not suitable for the Thanksgiving table into 500 barrels of bio-derived oil. The poultry leftovers come from a ConAgra turkey processing plant located next door. ConAgra produces about 75 common supermarket brand name foods, including Butterball, Chef Boyardee, Hebrew National and Marie Callender's, while Changing World Technologies specializes in processes that convert waste products into fuel.

"Anything you can do with petroleum out of the ground in Texas you can do with our product," said Terry Adams, the Chief Technology officer of Changing World Technologies. Adams said the company's first customer is blending the bio oil into home heating oil, and it can be refined into a gasoline or diesel fuel substitute. According to Adams, it costs Changing World Technologies about $16 per barrel to create the bio oil, which is competitive with the expense of locating and extracting petroleum.

Richard Lobb, spokesman for the National Chicken Council, is skeptical of the scheme, and doubts that using animal waste products to create fuel is financially feasible. Lobb said that petroleum is too cheap and animal protein too valuable to create a market. "There is a well-established channel of using animal rendering for industrial products, feed, and fertilizer," Lobb said.

Adams said that unlike other efforts that attempt to convert materials into oil in a single step, his company developed a two-step pyrolysis process that is more cost effective and fuel-efficient. The company's Thermal Conversion Process breaks down the materials so that minerals and other non-organics such as chlorine can be removed, Adams said. Then, the separated liquid organics go to the second stage of thermal processing to produce hydrocarbon oils.

"The basic idea has been around for the some time," Cohen said. The primary challenges are in creating a fuel that has sufficient lubricity (slipperiness) while minimizing the particulate matter that can "gum up" engines and also keeping the cost
