Without an engine, steering column or other conventional vehicle components, this concept provides unprecedented design freedom." 1-04
- Hydrogen Fuel Revolution (H2Cars.biz)
"This revolution will be every bit as transformative as the industrial and information revolutions which preceded it. What is really exciting is that no matter what answers we come up with, we are likely only scratching the surface. What will be the environmental impact of a clean, renewable energy source? What will be the economic impact of the cost of energy eventually falling to virtually nothing? What will be the geopolitical impact of devaluation of fossil fuels? The immediate changes are so enormous that it is easy to overlook the ripple effects, which will no doubt be of even greater magnitude. Just thinking about them renews my optimism about the future we are creating for our children and grandchildren," finishes Ms. Alpert." 5-04

- Trans Fats, Partially Hydrogenated Oils (BanTransFats.com)
"Partial hydrogenation is an industrial process used to make a perfectly good oil, such as soybean oil, into a perfectly bad oil. The process is used to make an oil more solid, provide longer shelf-life in baked products, provide longer fry-life for cooking oils, and provide a certain kind of texture or 'mouthfeel.' The big problem is that partially hydrogenated oil is laden with lethal trans fat." 9-05

At the same time, they can pave the way for a transition to fuel cell vehicles by building early demand for hydrogen infrastructure." 08-06
- Contamination With Sulfates or Hydrogen Sulfide (Water-Research.net)
"Sulfates and hydrogen sulfide are both common nuisance contaminants. Although neither is usually a significant health hazard, sulfates can have a temporary laxative effect on humans and young livestock. Sulfates also may clog plumbing and stain clothing. Hydrogen sulfide produces an offensive 'rotten egg' odor and taste in the water, especially when the water is heated."
"Treatment options depend on the form and quantities in which sulfates and/or hydrogen sulfide occur in untreated water- Therefore, it is critical that a comprehensive water analysis be conducted." 12-07
- Hydrogen Sulfide Removal Using Hydrogen Peroxide (Antoine.Forstberg.edu)
"Hydrogen sulfide and sulfur dioxide are waste products of several manufacturing processes, and reaction with peroxide is one fairly cost-effective method of removing them from industrial wastes." 12-07
- Why Hydrogen-Based Fuel Cells Are Not Plausible for Near Future (AlternateFuelsWorld.com)
"As anyone may discern from the briefest perusal of this Website, we believe that the peak of conventional oil production is likely within a few years, and that production from conventional natural gas resources may peak soon after. In as much as most hydrogen is produced from natural gas, and because production from renewables is very costly, fossil fuel scarcities will not prompt a widespread switch to hydrogen fuel in the near or mid term." 02-08

- Trans Fats, Finding (BanTransFats.com)
"Consumers can know if a food contains trans fat by looking at the ingredient list on the food label. If the ingredient list includes the words 'shortening,' 'partially hydrogenated vegetable oil' or 'hydrogenated vegetable oil,' the food contains trans fat. Because ingredients are listed in descending order of predominance, smaller amounts are present when the ingredient is close to the end of the list." 9-05
- -Coal Gasification (DOE.gov)
The United States generates over 50 percent of its electricity from coal plants. The USA is number one in the world in coal reserves.
"A coal gasification power plant, however, typically gets dual duty from the gases it produces. First, the coal gases, cleaned of impurities, are fired in a gas turbine - much like natural gas - to generate one source of electricity. The hot exhaust of the gas turbine is then used to generate steam for a more conventional steam turbine-generator. This dual source of electric power, called a 'combined cycle,' is much more efficient in converting coal's energy into usable electricity. The fuel efficiency of a coal gasification power plant can be boosted to 50 percent or more."
"Higher efficiencies translate into more economical electric power and potential savings for ratepayers. A more efficient plant also uses less fuel to generate power, meaning that less carbon dioxide is produced. In fact, coal gasification power processes under development by the Energy Department could cut the formation of carbon dioxide by 40 percent or more compared to today's conventional coal-burning plant."
"The capability to produce electricity, hydrogen, chemicals, or various combinations while eliminating nearly all air pollutants and potentially greenhouse gas emissions makes coal gasification one of the most promising technologies for the energy plants of tomorrow." 10-05

- Bio-Fuels From Genetics (MSN.com)
"J. Craig Venter, who gained worldwide fame in 2000 when he mapped the human genetic code, is behind a new start-up called Synthetic Genomics, which plans to create new types of organisms that, ideally, would produce hydrogen, secrete nonpolluting heating oil or be able to break down greenhouse gases." 11-05
- Bio-Fuels From Genetics (VenterInstitute.org)
"According to the U.S. Department of Energy approximately 80 percent of all human-caused carbon dioxide emissions currently come from fossil fuel combustion. The DOE also estimates that world carbon dioxide emissions are projected to rise from 6.1 billion metric tons carbon equivalent in 1999 to 7.9 billion metric tons per year in 2010 and to 9.9 billion metric tons in 2020. This continued consumption of fossil fuels is ample evidence that there is a growing need to eliminate carbon dioxide output into the environment and if possible capture back some of the carbon dioxide associated with global warming. The Biological Energy group is developing and using biological pathways and microbial metabolism to produce new fuels with higher energy output in an environmentally sound fashion. The team uses microbes, microbial genomics, microbial pathways, and plants as potential solutions to carbon sequestration and clean energy production. Current projects include: development of better understanding and reengineering of the photosynthetic pathway to divert the sun’s energy into more hydrogen production as well as reengineering cellulase pathways in certain bacterial to produce ethanol." 11-05
- Coal Gasification: FutureGen (DOE.gov)
