GM rethinks hydrogen fuel cells (http://www.usatoday.com/money/autos/2002-12-29-hybrid_x.htm)

Now we need to equip those hybrids as Flexible Fuel Vehicles (http://www.ccities.doe.gov/vbg/consumers/e85.shtml) that can burn either gasoline or ethanol, or any combination of the two fuels. Then we need a genome project to produce a saltwater seaweed with a high cellulose content, that can be used to produce unlimited supplies of ethanol, as in my essay entitled "Benthic Energy", near the bottom of my Starship Generations (http://geocities.com/womplex_oo1/StarshipGenerations.html) website.

Personally I prefer biodiesel. It smells good.

You would need to do some fancy synthetic chemistry to convert the cellulose into glucose if you want to make ethanol from it.

No, it's nothing fancy. Just a weak sulfuric acid solution should do the trick. Then add yeast to ferment the glucose into ethanol.

I wish it wasn't so dangerous to refine yourself, otherwise I'd be free of the diesel pump now. I'm hoping that the availability in my area grows, because it not only smells better and pollutes less, it better for the engine as well.
