Ethanol is for drinking. « Blogging »

Seriously.

Ethanol fuel for cars sounds nice, but there are significant problems with it as a motor fuel. Biomass waste doesn't give enough energy, only foodstuff biomass, and then you are switching cropland from growing food to growing fuel. It doesn't make sense economically or ecologically.

That's why I like the functional electric car (i.e., what Tesla Motors is developing). No sacrifice in driving pleasure, AND it provides more distance per penny than other propulsion methods. Hydrogen can't replace energy use, it just uses a different medium to deliver energy that still needs fossil or hydro fuels to produce (since the Greens won't allow nuclear), and since it is a medium, rather than a direct transfer, you lose energy in the transactions. An electric car wastes less energy by being a direct electric transfer. Not to mention I could have solar cells on the roof of my garage and house, further reducing the cost/carbon footprint/energy waste/use of the Tesla cars.

Also, the projected Honda Accord diesel is expected to be a fuel-sipper, and ultra-clean to boot. I expect bio-diesel could be in the works for regular diesel cars in another decade, making ultra-efficient, ultra-clean diesels a better choice than ethanol OR hydrogen cell OR hybrid.

Why do US carmakers miss the boat on these sort of issues so often?
