The Environment

You may be right about the hybrid vehicles. But the public transportation may only make sense in densely populated city areas. Interestingly, I just saw the documentary film, "Who Killed the Electric Car?" It's disheartening to see big business moth ball a viable technology to further a profit seeking agenda. GM actually built a production model electric car that had zero emissions; but the whole program was killed due to a big industry propped by the oil interests. Opponents backed by big oil companies claimed that the indirect emissions from coal-burning plants that would produce the required electricity for the electric cars would dwarf the current pollution spewed out by internal combustion engines. Whether that is true or not is left to the imagination since we can't even get a hold of a zero-emission electric vehicle anymore; so, there is no way currently to make accurate measurements. Good points about alternative fuels. I think in the long run, it won't be a single technology that will be the panacea for our environmental woes. It'll take a variety of alternatives based on need and practicality that will help fix the environment; technologies ranging from solar, electric, wind, wave energy (from oceans), hydrogen...
