@av8tor17b there is a food vs fuel problem when there is food scarcity around the world. food comes first to all...then we can drive our cars...

@sardakur ..... if they are growing hemp they will still be using the land for something other than food won't they ,,, land on which food used to be grown ..... unless you want to clear more forests to create new land on which to grow your hemp. There is no free lunch. People keep forgetting the hidden costs as well as the negative side effects.

as George W. was saying - the best way to break this addiction is to get addicted to something else :)

Corn ethanol is energy negative. Making it useless and damaging on a macroeconomic scale.

How about using hemp instead and then your food prices wouldn't be affected. Plus hemp can be used to make more then two thousand other products and will save cutting down trees.

ethanol takes more energy to produce than it contains

this just automatically got into my favs o-O

@machhone not true! the truth is we don't even need to use food products to create fuel. we can create fuel from yard waste, any vegatation waste, even algae which scrubs waste products from other manufacturing and turns that waste into energy that you can use. the food markets don't have to be affected at all. the best thing about it all is that the energy requirements to create the fuel are negligible; the fuel practically creates itself. things will change and soon at that.

I also do not believe the message that there's a WIDESPREAD OR LONG TERM problem of using corn for corn-based ethanol, instead of strictly for food uses. (This does not mean that there are not issues in some communities, but the problem is not as bad or the reason as clear as this video implies). We already use corn for so many things besides food. Corn can be used for hundreds of things.

The most exhaustive study on ethanol’s EROEI, by Isaias de Carvalho Macedo, shows an alcohol energy return of more than eight units of output for every unit of input—and this study accounts for everything right down to smelting the ore to make the steel for tractors.
There is no "food vs. fuel" problem.
We are producing record corn crops on less land, and still exporting as much or more corn than ever before. Byproducts of ethanol include DDG, used for animal feed, and corn oil, for either food or biodiesel use.
You all need to learn more about ethanol before you make yourself look foolish. Corn is the beginning- soon Cellulostic ethanol will grow, as will fuel from algae. All produce ethanol at a reasonable cost.

@pegobuilders Also, fermenting the corn to alcohol results in more meat than if you fed the corn directly to the cattle. We can actually increase the meat supply by first processing corn into alcohol, which only takes 28% of the starch, leaving all the protein and fat, creating a higher-quality animal feed than the original corn.
