The real problem with ethanol...
Observe this graph. Now listen to this outstanding, straightforward explanation* why corn-based ethanol is not the answer to our energy problem.
I'm not saying it isn't the answer to our farm income problem (short term), it's just not a faintly viable alternative to oil.
It's not oil price. It's not government policy. It's not bad guys in the MidEast.
It's too much effort for too little reward.
Oil is like nothing else in the world. We just don't appreciate how much good living is packed in every barrel.
*Actually the whole "Crash Course" is very well done.
