Not that the alternative fuels ideas were silly. Well, some were, but mostly they were good and just need the right economic conditions for them to come on stream. Hydrogen is no specially good as a fuel, especially as carting it around is hard work. It's better to burn the cheap, easy stuff, such as crude oil. After that runs a bit short [not for a long time yet] then photovoltaic hydrogen is available by the ocean full. CO2 is good stuff. The ecosystem has been starved of it for eons as it got buried by subduction under tectonic plates and in sedimentary layers, coal deposits and tar sands. It's time to get the CO2 back into the ecosphere. Plants are hungry! They want tucker. Why use hydrogen when we can use cheap, safe fuels? Where would the hydrogen come from? If from fossil hydrocarbons, would you just dump the carbon, unburned? Oil can be burned cleanly for transport in cities. Sure, we don't want highly aromatic high sulphur fuels for city use is diesel engines, but turbines are clean-burning. Fuel cells are too expensive and unnecessary for vehicles [maybe buses and other high mileage vehicles could use them economically]. That's all part of the new paradigm which will forestall the great financial collapse and make our lives better. Consumerism is great - we need lots more clean-burning gadgets. The only thing I have against H2 is the cost [safety might be a worry, but with care it could be okay]. Cost is important to nearly everyone on the planet. For example, listen to Californians whining about the government control of electricity causing shortages and high prices. Listen to the SUV owner whining about high gasoline prices. Cost counts! Sure they want clean-burning, but clean-burning and cheap is best. Forget about hydrogen. My ex-boss liked it [in the early 1980s and early 1970s, but it is too expensive]. Crude oil and natural gas remain and will remain the best energy sources for transport [unless econuts get to mess things up]. Natural gas to methanol might be useful in fuel cells. Mqurice
