The September 2006 issue of Scientific American is devoted to Energy's Future Beyond Carbon. In it is an article on Fueling Our Transportation Future. Overview The massive use of petroleum-based fuels for transportation releases immense ammounts of carbon dioxide into the atmosphere -- 25 percent of the total worldwide. Options for constraining and eventually reducing these emissions include improving vehicle technology, reducing vehicle size, developing different fuels, and changing the way vehicles are used. To succeed, we will most likely have to fallow through on all of these choices. The only thing I didn't like or understand about the article was the timescales chart on page 62, in which they give the time till a "Market competitive vehicle" as 5 years for a "Gasoline hybrid" and as 5 years for a "Turbocharged gasoline engine". :huh: What's up with that? It cites MIT's Laboratory for Energy and the Environment as its source.
