A while back I was in a place where two libs were going on about how ethanol is a great fuel, saving the earth and all that.
I told them ethanol is a horrible fuel unless you were talking about some fondue pot or a modified Bunsen burner.
After the ranting and blubbering subsided, I managed to say that at least in the case of internal combustion engines, the quality of any fuel is measured by the heat that can easily be released from a given quantity. I suggested they get a thimble of ethanol and a thimble of gasoline and stick a match to each one. Easy science project with easily noticeable results.
They were not persuaded, my argument did not fit the lib logic.

Tell them to drink the alcohol and pour the gasoline in their hair.

In other words, to quote Walter Matthau and Jack Lemmon in Grumpier Old Men--

Lemon: C'mon, Max, let me in, it's cold out here.

Matthau: Here's a box of matches, set yourself on fire.

Cheers!
