See what I mean? This article doesn't even mention EROEI one time! And you claim it completely debunks the criticism.
Lets look at the quotes I listed for you from that artical again ....
Quoting the article: "Until we developed this new technology, the chemical makeup of biomass prevented it from being used to make ethanol economically," Ingram said. "Biomass is a much cheaper source of ethanol than traditional feedstocks such as corn and cane syrup.
"The new technology will allow ethanol to become economically competitive with fossil fuels for the first time," he said. "Until now, all the world's ethanol has been produced by yeast fermentation, which converts sugars into ethanol, carbon dioxide and other by-products."
"Instead of using corn or grain to make ethanol fuel, they'll be used to feed people," said BCI Executive Vice President Clinton Norris. "With this new technology, we can provide a source of energy by utilizing waste from farm crops -- not the crops themselves. In this way, we're helping solve the problems of hunger and our endangered environmental resources."
What part of this are you not getting? Is it the part saying used to make ethanol economically competitive? Was it other things in that post like cheaper fuel than gasoline Was it the part showing oil usage is not needed for any of it?
