Today air pollution and global warming are the two most important environmental hazards faced by humankind. Both have a direct link with our current over-dependence on fossil fuels. Pollutants produced from combustion of hydrocarbons now cause even more health problems. The net increase in environmental carbon dioxide from combustion is a susceptible cause for global warming, which is endangering earth? the only known place to support human life. In addition, the import of expensive hydrocarbon fuel has become a heavy burden on many countries, causing political and economic unrest. If we look at the past 2000 years' history of fuels, usage has consistently moved in the direction of a cleaner fuel: wood? coal ? petroleum ? propane ? methane. With time, the fuel molecule has become smaller, leaner in carbon, and richer in hydrogen. The last major move was to opt for methane as a fuel; it is a much cleaner burn than gasoline.
