This is just pain ignorant ... yeah, there are plenty of fast food restaurants,
so where does all that oil come from? And what is the maximum amount
of oil that it can create ... it is not an answer to energy independence.
Yes, because the writer/director/main character was suggesting that the only source of oil to produce biofuel comes from fast food places. I don't think that he was implying that it will provide energy independence. What he was saying was that we could greatly reduce our dependence on foreign oil if we shifted our means of transportation to biodiesel. If that were the case then I can imagine corn production would go up even more than it is now. You act like we have a finite amount of resources to produce biofuel. Unlike traditional oil, you can grow the products necessary to produce biofuel.

I think most believe that using foodstuffs to make oil is very wrong, and inefficient.
There was scientists who are working on bacteria that produce biodiesel with seems
like a good idea, but again, it is still creating CO2.
We do have have a finite amount of resources to produce biodiesel, there is a finite
amount of farmland, and what is used as biodeisel takes away from food.
Corn production is very oil/gasoline intensive a well.
There is no way to replace foreign oil with agriculturally grown biodiesel.
Please think before you post.
Really? So you know exactly how much farmland we have in this country? You know for sure that we don't have enough? The difference between biodiesel which can be produced on top of materials for food and regular oil is that we can harvest the biomaterials and then regrow them, and we can't regrow oil. On top of that, they even discussed the use of algae to make biodiesel. Algae actually consumes CO2. Corn production is very gasoline intensive because of the gas used in the farm equipment. Since they already have diesel engines, they could actually use the biodiesel that comes from what the machines are actually harvesting. You have no idea if it is possible to replace foreign oil with agriculturally grown biodiesel. Strictly dismissing the idea on the face of it is beyond ignorant. Did you even watch all of this movie?

Follow your own suggesting m-on
Research into algae for the mass-production of oil is mainly focused on microalgae; organisms capable of photosynthesis that are less than 0.4 mm in diameter, including the diatoms and cyanobacteria; as opposed to macroalgae, such as seaweed.
I love it. Twice now you've suggested I follow my own signature, yet I haven't said anything at all which does not demonstrate an understanding of what you wrote. Give it up.
On the note of your actual comment, I'm failing to see how that matters. Research might be in microalgae right now, but have all macroalgae been deemed impossible to use for biofuel? Note in my previous comment that I didn't say that algae was automatically the solution if corn, etc doesn't fully satisfy. I wrote, "On top of that." Why is it that you found it necessary to falsely focus on one part of my comment?

--Fuels made from biomass are a lot like the nuclear powered airplanes the Air Force tried to build from 1946 to 1961, for billions of dollars. They never got off the ground. The idea was interesting -- atomic jets could fly for months without refueling. But the lead shielding to protect the crew and several months of food and water was too heavy for the plane to take off. The weight problem, the ease of shooting this behemoth down, and the consequences of a crash landing were so obvious, it’s amazing the project was ever funded, let alone kept going for 15 years.
--Fertile soil will be destroyed if crops and other "wastes" are removed to make cellulosic ethanol.
"We stand, in most places on earth, only six inches from desolation, for that is the thickness of the topsoil layer upon which the entire life of the planet depends" (Sampson 1981).
--Loss of topsoil has been a major factor in the fall of civilizations (Sundquist 2005 Chapter 3, Lowdermilk 1953, Perlin 1991, Ponting 1993). You end up with a country like Iraq, formerly Mesopotamia, where 75% of the farm land became a salty desert.
