RFOL, I wish I had more of those days at work. They block a lot of stuff at work too. So I mostly just read the news and google stuff. Just found this interesting article in Rolling Stone about ethanol. I have heard that ethanol wasn't the answer but I didn't realize it was so bad.

Ethanol Scam: Ethanol Hurts the Environment And Is One of America's Biggest Political Boondoggles : Rolling Stone

But as a gasoline substitute, ethanol has big problems: Its energy density is one-third less than gasoline, which means you have to burn more of it to get the same amount of power. It also has a nasty tendency to absorb water, so it can't be transported in existing pipelines and must be distributed by truck or rail, which is tremendously inefficient.


Nor is all ethanol created equal. In Brazil, ethanol made from sugar cane has an energy balance of 8-to-1 -- that is, when you add up the fossil fuels used to irrigate, fertilize, grow, transport and refine sugar cane into ethanol, the energy output is eight times higher than the energy inputs. That's a better deal than gasoline, which has an energy balance of 5-to-1. In contrast, the energy balance of corn ethanol is only 1.3-to-1 - making it practically worthless as an energy source. "Corn ethanol is essentially a way of recycling natural gas," says Robert Rapier, an oil-industry engineer who runs the R-Squared Energy Blog.
