Ethanol makes good economic sense — and is essential for our national security.
I know it’s widely believed that it takes as much energy to make corn ethanol as it produces, but that’s been disproven mathematically by energy expert Robert Zubrin, author of Energy Victory.
Also, there are many crops that require much less cultivation than corn (e.g. sugar cane, many weeds) and over time those are likely to win out in a competitive market.
Indeed, over time it should be expected that crops that grow wild or easily in tropical climates will be the cheapest fuel sources.
I’m all for nuclear plants and electrical cars, and those are coming — but not as quickly as we need in order to diminish the wealth transfer now underway to the Saudis, the Iranians, Chavez, Putin, et al.
