I've been making a mental list of all the things I've seen touted as being the potential "fuel of the future" -- you know, the thing that will finally wean us off our oil addiction. Now seems like a good time to download. So, off the top of my head (and scattered in notes around my desk) here goes: Corn, corn stover, soybeans, oil palm, sugar cane, bagasse, switchgrass, jatropha, goldenrod, karanj (pongam), ragweed, rapeseed (canola), flaxseed, hemp, filbert (hazelnut), poplar, willow, castor bean, miscanthus, milo, mustard seed, poultry fat, beef tallow, wood chips, bamboo, yucca (cassava), fryer grease, saltbrush, cassava, citrus peels, milk plasma (whey), algae.

What am I forgetting? No, coal doesn't count.
